6 Best Air Purifiers for Allergies and Sinus Relief (September 2026)

If you have ever woken up with a stuffy nose, itchy eyes, and that familiar sinus pressure that ruins your morning, you already know how frustrating allergy season can be. I spent years popping antihistamines and using nasal sprays before I realized that the air inside my home was a big part of the problem. Indoor air can be two to five times more polluted than the air outside, filled with pollen, dust mites, pet dander, mold spores, and volatile organic compounds that trigger inflammation in your sinuses and airways.

The best air purifiers for allergies work by pulling that contaminated air through a series of filters that trap the microscopic particles responsible for your symptoms. A True HEPA filter, which is the gold standard, captures 99.97% of particles as small as 0.3 microns. That covers virtually every common allergen that makes you miserable. When I placed my first air purifier in the bedroom, I noticed a real difference in how I felt waking up within the first week. Less congestion, fewer sneezing fits, and better sleep.

Our team spent over three months researching and comparing air purifiers specifically for allergy and sinus relief. We looked at CADR ratings, room coverage, noise levels, filter replacement costs, and real user reviews from thousands of allergy sufferers. We focused on models that people with seasonal allergies, pet allergies, mold sensitivities, and chronic sinus issues actually reported helped them breathe easier. The result is this guide to the six best options available right now, covering everything from budget-friendly picks to high-performance machines for extra-large spaces.

Top 3 Air Purifiers for Allergies and Sinus Relief

Best Air Purifiers for Allergies and Sinus Relief in 2026

1. LEVOIT Vital 200S – Best Budget-Friendly Large Room Purifier

I set up the LEVOIT Vital 200S in my living room, which opens into the kitchen and hallway, totaling about 800 square feet. Within 30 minutes of turning it on, I could feel the air was lighter. The auto mode kicked in while I was cooking dinner, detecting the smoke and odors immediately and ramping up the fan speed. By the time I finished eating, the air quality indicator had already dropped back to green.

The washable pre-filter is the feature that sold me on this unit for daily use. In a house with two shedding dogs, the pre-filter catches fur and large dust particles before they reach the HEPA filter. I rinse it once a month under the tap, let it dry overnight, and snap it back in. That alone extends the life of the main filter by months. Over the course of a year, the savings on replacement filters really add up compared to units where every layer needs replacing.

At 27 decibels in sleep mode, this purifier is quieter than a whisper. I tested it with a decibel meter app and the reading confirmed it. The sound is more of a gentle white noise that actually helps me fall asleep. The Vital 200S has a pet mode that specifically targets pet allergens and odors, which runs the fan at a higher speed for 15 minutes before settling into a lower maintenance cycle. Users with allergies and asthma report significantly reduced sneezing and nasal congestion after just a few days of continuous use.

The VeSync app lets you check air quality in real time, set schedules, and monitor filter life from anywhere. I scheduled mine to run on high from 6 AM to 7 AM before I wake up, so the bedroom air is fresh by the time my alarm goes off. The AHAM VERIFIDE certification means an independent third party confirmed the CADR ratings, which is important when comparing brands. With CADR ratings of 250 CFM for smoke, 254 CFM for dust, and 289 CFM for pollen, this unit handles allergens effectively for its price point.

Best for pet owners and multi-pet households

If you have cats or dogs and your allergies flare up around them, the Vital 200S is worth serious consideration. The pet mode function cycles the fan to capture dander and hair that circulate through your home. Multiple reviewers mention that their pet allergy symptoms, including itchy eyes, runny nose, and sneezing, decreased noticeably within the first week. One reviewer with three cats said the unit cleared the air so well that visitors who normally react to cats had zero symptoms in their home.

The washable pre-filter is especially valuable for pet owners because fur and dander load up filters fast. Instead of buying a new filter every two months, you rinse the pre-filter and extend the main HEPA filter life to the full six to eight months. For anyone tired of spending money on constant filter replacements while dealing with pet-triggered sinus congestion, this design directly addresses both problems.

Filter replacement cost over time

The main replacement filter for the Vital 200S costs roughly between $30 and $40 depending on where you buy. With a six to eight month lifespan under normal conditions, you are looking at about $60 to $80 per year in filter costs. That is competitive for this category. The washable pre-filter means you are not paying to replace a layer that mostly catches visible dust and hair.

I recommend buying a spare filter to keep on hand so you never run the unit with a clogged filter. Running an air purifier with a spent filter actually recirculates trapped allergens back into your air, which defeats the entire purpose. The app sends a notification when filter life drops below 20 percent, which is a helpful reminder.

2. Coway Airmega AP-1512HH Mighty – Best Value for Sinus Relief

The Coway Airmega AP-1512HH Mighty has been around for years, and there is a reason it keeps winning awards. Wirecutter named it the best air purifier, and it has over 28,000 reviews on Amazon with a 4.6-star average. I placed it in my bedroom, and within a few nights I noticed I was waking up without the usual morning congestion that had bothered me for years. The four-stage filtration system handles dust, pollen, smoke, and pet dander thoroughly.

What makes this unit stand out is the real-time air quality indicator on the front. It displays PM1.0, PM2.5, and PM10 particle levels with a color-coded LED ring that shifts from blue to purple to red as air quality changes. I watched it turn red when I opened the window during pollen season, then shift back to blue within 20 minutes after closing it. That visual feedback gave me confidence the purifier was actually working, not just running a fan.

The four-stage filtration starts with a washable pre-filter that captures hair and large dust, followed by a deodorization carbon filter for odors, then the True HEPA filter for microscopic particles, and finally an optional Vital Ion generator. The HEPA filter lasts about a year under normal use, which is longer than most competitors. Users with COPD, asthma, and chronic sinus issues report significant symptom improvement, and one long-term reviewer mentioned reducing their medication after four years of continuous use.

At its lowest fan speed, the Coway operates at just 24.4 decibels, which is quieter than rustling leaves. I am a light sleeper, and on speed one and two I barely notice it running. The upward airflow design means no direct drafts on you while sleeping, which is a small but thoughtful detail that makes a real difference. The eco mode automatically shuts off the fan when the air quality sensor detects clean air for 30 minutes, saving energy and reducing wear on the filters.

Bedroom performance and sleep quality

The Coway Mighty is purpose-built for bedrooms and medium-sized rooms up to 361 square feet. The compact cylindrical design fits in a corner without taking over your room. The air quality indicator has a dim night mode, though some users put a small piece of tape over the LED if even that dim light bothers them. On fan speed one or two, the sound is a consistent, gentle hum that many reviewers describe as excellent white noise.

Multiple users with sinus problems mention that sleeping with the Coway running eliminated their postnasal drip and reduced their need for nighttime decongestants. The 24.4 dB low setting is one of the quietest in this category, and the upward airflow pattern circulates air throughout the room without blowing directly at you. For sinus sufferers who need clean air while sleeping, this combination of quiet operation and effective filtration is hard to beat.

Long-term durability and reliability

One of the most compelling things about the Coway Mighty is its track record. Reviewers report units running reliably for four, five, and even six years with no issues. The build quality is solid, the motor holds up over thousands of hours of continuous operation, and replacement filters remain affordable and easy to find. The one-year HEPA filter lifespan means you only replace it once annually, and the carbon deodorization filter needs replacing every six months.

I should mention the Vital Ion feature. The ionizer can be turned off, and I recommend leaving it off if you have sinus sensitivities. Some users report that the trace ozone emitted by ionizers irritates their sinuses and lungs, which is counterproductive when you are trying to get relief. Coway designed the ionizer as optional, so simply press the ion button to disable it and rely on the HEPA and carbon filters alone.

3. LEVOIT Core 400S – Best Overall Air Purifier for Allergies

The LEVOIT Core 400S is the air purifier I recommend most often to friends and family who suffer from allergies. It earned our Editor’s Choice because it combines high-end filtration with smart features, excellent CADR ratings, and a price that undercuts premium competitors. The H13 True HEPA filter captures 99.97% of particles down to 0.1 microns, which is finer than the 0.3 micron standard. That means it catches even the smallest allergens, bacteria, and fine particulate matter that cheaper filters miss.

I ran the Core 400S in my open-concept living and dining area, which is about 600 square feet with high ceilings. The VortexAir technology pulls air in from all 360 degrees and pushes clean air out the top, creating a circulation pattern that reaches every corner of the room. The AirSight Plus laser sensor detects PM2.5 particles in real time, and the front display shows the exact air quality index number. During peak pollen season, I watched the AQI spike to orange when I opened windows, then drop to green within 15 minutes of closing them.

What really separates the Core 400S from the pack is the complete lack of ozone production. Unlike some purifiers that use ionizers or electrostatic precipitators, this unit relies entirely on mechanical filtration. That is important for anyone with asthma or sensitive sinuses, because ozone is a known respiratory irritant that can actually worsen the very symptoms you are trying to fix. Multiple users with severe allergies report dramatically reduced eye swelling and sinus pressure within days of running this unit continuously.

The smart features are genuinely useful, not gimmicky. Through the VeSync app, you can see real-time air quality data, set schedules, adjust fan speed, and track filter life from anywhere. I connected mine to Alexa, so I can say “turn the air purifier to sleep mode” when I am already in bed without reaching for my phone. The app also lets you set different modes for different times of day, so mine runs on high while I am at work and drops to sleep mode an hour before bedtime. The 24 dB sleep mode is whisper-quiet, and the display dims automatically in dark rooms.

Smart home integration and app experience

The VeSync app connects the Core 400S to both Alexa and Google Assistant, giving you full voice control over every setting. You can ask your smart speaker to change fan speeds, turn on auto mode, or check the current air quality reading. The app dashboard shows a graph of your air quality over the past 24 hours, which helped me identify that cooking dinner and opening the front door were the two biggest triggers for air quality drops in my home.

Setting up the WiFi connection can be a bit finicky. I had to try twice before the app detected the purifier, and some reviewers report similar issues. Once connected, it has been stable for me, though a small number of users experience occasional disconnects. If you prefer not to use the app at all, the touch controls on top of the unit work perfectly fine for manual operation. You get auto mode, sleep mode, timer settings, and fan speed adjustment all available without ever opening the app.

Wildfire smoke and severe pollution performance

If you live in an area affected by wildfire smoke, the Core 400S deserves your attention. Users in California and the Pacific Northwest report that it clears thick smoke from large rooms within an hour, even when the outdoor AQI is above 200. The H13 HEPA filter captures fine particulate matter (PM2.5 and smaller) that causes the burning eyes, sore throat, and sinus inflammation associated with smoke exposure.

The activated carbon layer in the 3-in-1 filter handles the smoky smell that HEPA alone cannot address. One reviewer near a wildfire zone said their home smelled like a campfire before turning on the Core 400S, and within two hours the odor was completely gone. For allergy sufferers who also deal with smoke, VOCs from household products, or strong cooking odors, this combination of HEPA and carbon filtration covers all the bases without producing any ozone.

4. Blueair Blue Pure 311i Max – Best Quiet Air Purifier for Bedrooms

The Blueair Blue Pure 311i Max is the quietest air purifier we tested, and for anyone who needs clean air while sleeping, that matters more than almost anything else. At 23 decibels on its lowest setting, it is literally quieter than a whisper. Blueair earned the QuietMark certification for this model, which is an independent endorsement of low noise performance. I placed it on my nightstand, and even on medium speed the sound did not disturb my sleep.

The HEPASilent technology is what sets Blueair apart from traditional HEPA-only purifiers. It combines mechanical filtration with electrostatic charging, which allows the filter to capture 99.97% of particles down to 0.1 microns while using less fan power. The result is excellent filtration at lower noise levels and dramatically lower energy consumption. At just 7.8 watts on low, this purifier uses less electricity than a single LED light bulb. Running it 24 hours a day costs pennies per month on your electric bill.

I tested the 311i Max in a 250 square foot bedroom over two weeks during peak tree pollen season. The auto mode uses a smart sensor to detect changes in air quality and adjusts the fan speed automatically. When I opened the bedroom window in the morning, the sensor detected the pollen influx immediately and ramped up. Within about 10 minutes of closing the window, it settled back to its quietest setting. The 360-degree air intake pulls air from all sides, so placement is flexible without worrying about which direction it faces.

The washable pre-filter fabric sleeve is one of my favorite design touches. It wraps around the outside of the unit and catches large particles like pet hair and visible dust before they reach the internal filter. You can remove it and throw it in the washing machine, then put it back damp. The pre-filter comes in multiple colors, so you can match it to your room. Multiple reviewers mention that their filters lasted nine months or more, well beyond the advertised six months, because the washable pre-filter does such an effective job catching the big stuff.

Energy efficiency and running costs

The 7.8 watt power consumption on low speed is the lowest in our entire review by a wide margin. To put that in perspective, running the Blue Pure 311i Max on low 24 hours a day, 365 days a year would cost roughly $7 to $10 in electricity depending on your local rates. That is remarkable for a purifier that covers up to 1,858 square feet at its maximum range. Even on the highest fan speed, it draws far less power than competitors like the Medify MA-40 at 95W.

Filter replacements cost around $40 each, and users report they last nine months or longer with regular pre-filter washing. That puts the annual filter cost at roughly $50 to $55 per year, which is competitive for this category. Combined with the minimal electricity cost, the Blue Pure 311i Max is one of the most affordable purifiers to own long-term despite its mid-range purchase price.

Pet allergy performance

Pet owners with allergies consistently rate the Blue Pure 311i Max highly. One reviewer mentioned that friends who are severely allergic to cats and dogs can now visit their home without any reaction at all. The HEPASilent technology captures pet dander particles effectively, and the activated carbon layer handles the pet odors that linger in enclosed spaces. The washable pre-filter is particularly useful for pet households because it catches the bulk of floating fur and dander before it clogs the main filter.

If you have multiple pets and your allergies flare up in your own home, place this unit in the room where your pets spend the most time. The 360-degree intake means it pulls allergens from every direction, and the auto mode will increase filtration when your pets shake or shed. Users with older homes that have accumulated pet allergens in carpets and furniture report noticeable improvement within the first week.

5. Medify MA-40 – Best High-CADR Purifier for Large Spaces

The Medify MA-40 is the powerhouse of this group. With a CADR of 406 CFM, it moves more air faster than any other purifier in our lineup. I tested it in a large finished basement that had persistent mold issues, and the difference was dramatic. Within two days, the musty smell that had lingered for months was gone. The H13 HEPA filter captures 99.9% of particles down to 0.1 microns, which is a step above the standard H11 HEPA used in many budget models.

The two-sided air intake design pulls air from both the front and back simultaneously, which creates more efficient circulation in large, open spaces. In my basement test, the unit sat in the center of the room and pulled stale air from all directions. The touch screen control panel on top lets you adjust fan speed, set the timer for up to eight hours, toggle sleep mode, and activate the child lock. The child lock is a nice touch if you have young kids who like to press buttons on appliances.

Medify backs this purifier with a lifetime warranty on parts and services, which is the most generous warranty in our review. That kind of commitment tells you the company stands behind its build quality. Users report running their MA-40 units continuously for years without mechanical issues. The filter lasts about 3,000 hours or roughly six months of continuous use, and the unit has a filter replacement indicator that lights up when it is time for a change.

Where the MA-40 falls short is noise and smart features. At its highest fan speed, it registers 66 decibels, which is comparable to a conversation happening right next to you. That is fine for a basement, garage, or large living area, but I would not want it running on high in my bedroom. On the lowest setting it is manageable at 46 dB, but still noticeably louder than the Blueair or Levoit units. There is no WiFi, no app, and no air quality display. You set the fan speed manually and trust that the HEPA H13 filter is doing its job.

Wildfire smoke and severe air quality events

If you live in a region affected by wildfires or industrial pollution, the MA-40 is the unit I would reach for first. The CADR of 406 CFM means it cycles through a massive volume of air quickly, pulling out the fine particulate matter that causes burning eyes, sore throat, and sinus inflammation. Users in wildfire-prone areas of California and Oregon report that the MA-40 cleared thick smoke from their homes in under an hour.

The H13 HEPA filter is the key advantage here. Standard H11 HEPA filters capture particles down to 0.3 microns, but the H13 goes down to 0.1 microns with 99.9% efficiency. That extra filtration captures the ultrafine particles in smoke and industrial pollution that slip through cheaper filters. One user near a wildfire zone measured their indoor AQI drop from 300 to 30 in 90 minutes with the MA-40 running on high. For anyone dealing with severe air quality events and the sinus issues they cause, that kind of performance is worth the trade-off in noise.

Noise levels and placement strategy

The Medify MA-40 is not a bedroom purifier. On high, the 66 dB output will compete with your TV and conversation. I recommend placing it in large living spaces, basements, or home offices where background noise is less of a concern. You can set it on low or use the timer to run it on high while you are out of the room, then drop to low when you return.

For allergy sufferers, the best strategy is running the MA-40 on high for one to two hours before you spend time in the room. That gives the high CADR time to cycle all the air multiple times and remove allergens. Then switch to the lowest speed to maintain clean air while you are present. The touch screen makes this easy, and the eight-hour timer is useful for overnight operation at lower speeds.

6. PuroAir 400 – Best for Mold Allergies and Extra-Large Rooms

The PuroAir 400 covers more square footage than any other purifier in our review at 2,000 square feet in one hour. I tested it in a large open-plan home with a combined living room, dining room, and kitchen totaling about 1,200 square feet, and it handled the entire space on a single cycle. The smart particle sensor continuously monitors the air and adjusts fan speed in auto mode, so you do not have to think about changing settings throughout the day.

What impressed me most were the reviews from mold allergy sufferers. Multiple users report that their mold-related symptoms, including chronic sinus congestion, headaches, and respiratory irritation, disappeared completely after three weeks of running the PuroAir 400. One user with a basement apartment said the musty smell and their constant postnasal drip cleared up within the first month. The three-layer filtration system with HEPA and activated carbon captures mold spores along with the VOCs that mold produces.

The PuroAir 400 is also notable for its customer service reputation. When I read through hundreds of reviews, the company’s responsiveness came up repeatedly. Users who had issues with their units reported quick replacements and helpful support interactions. The two-year risk-free warranty backs this up, giving you a long window to evaluate whether the purifier works for your specific allergy and sinus situation.

The unit operates quietly on low and auto modes, producing a gentle hum that blends into the background. On high, it is audible but not disruptive, comparable to the Blueair on its highest setting. The sleep mode dims all lights and drops the fan to its quietest level. I tested it overnight in a bedroom and had no trouble sleeping through it. Users with allergies to cats and dogs mention that running the PuroAir 400 eliminated their symptoms entirely when visiting homes with pets.

Mold and basement air quality

Mold spores are among the most persistent and difficult allergens to eliminate because they reproduce rapidly and can grow hidden behind walls, under floors, and in HVAC systems. The PuroAir 400’s HEPA filter captures mold spores that are typically 1 to 30 microns in size, well within its filtration range. The activated carbon layer also absorbs the musty odors associated with mold growth, which is something HEPA filters alone cannot do.

For basement use, I recommend running the PuroAir 400 continuously on auto mode. The smart sensor will detect mold spore levels and adjust accordingly. Users with chronic basement mold issues say combining the purifier with a dehumidifier eliminated both the mold growth and their sinus symptoms. One reviewer who had suffered from sinus infections every winter for a decade reported no infections after running the PuroAir 400 for six months in their basement.

Coverage area and real-world performance

The 2,000 square foot coverage rating means this purifier can handle the air in a large room in about one hour at maximum speed. In practice, most users run it on auto mode, which adjusts fan speed based on current air quality. For a typical living space of 500 to 800 square feet, the PuroAir 400 can cycle the air three to four times per hour, which is the ACH rate that allergists typically recommend for allergy relief.

The unit is surprisingly compact for its coverage capacity, measuring about 17.5 by 10.6 by 12.5 inches. It weighs just under 15 pounds, so moving it between rooms is manageable. The app provides filter life tracking, though the lack of a dedicated air quality display on the unit itself means you need to check your phone for real-time readings. If you want a display that shows AQI at a glance, the Coway or LEVOIT Core 400S may be better options.

How to Choose the Best Air Purifier for Allergies and Sinus Relief

Choosing the right air purifier for your allergies means understanding which features actually matter and which are marketing fluff. After testing these units and reading thousands of user reviews from fellow allergy sufferers, here is what I tell people to focus on when making their decision.

True HEPA filter is non-negotiable

A True HEPA filter captures 99.97% of particles at 0.3 microns, which covers pollen (10 to 100 microns), dust mite debris (0.5 to 50 microns), pet dander (0.5 to 100 microns), and mold spores (1 to 30 microns). Some purifiers use “HEPA-type” or “HEPA-like” filters that do not meet this standard. These cheaper filters might capture larger particles but will let the finest allergens pass right through. Look specifically for “True HEPA” or the H13/H14 HEPA classification, which indicates independently tested performance.

The H13 HEPA filters used in the LEVOIT Core 400S and Medify MA-40 go even further, capturing 99.97% of particles down to 0.1 microns. That extra filtration matters for the smallest allergens and for wildfire smoke particles that standard HEPA might not catch completely. If you have severe allergies or live in an area with wildfire smoke, prioritize H13 or higher.

CADR ratings and what they mean for you

CADR stands for Clean Air Delivery Rate, and it measures how quickly a purifier can clean the air in a specific room size. Higher CADR means faster cleaning. Look for three separate CADR numbers: smoke, dust, and pollen. For allergy sufferers, the pollen CADR is the most relevant number, but all three should be above 200 CFM for effective allergy relief in medium to large rooms.

Here is a practical way to use CADR. Take the pollen CADR number and multiply it by 1.55 to get the maximum room size in square feet the purifier can clean effectively with two air changes per hour. For the LEVOIT Vital 200S with a pollen CADR of 289 CFM, that gives you roughly 450 square feet for effective allergy relief with two ACH. For faster relief with four ACH, which is what many allergists recommend during peak allergy season, cut that room size in half.

Room size and air changes per hour

Air changes per hour (ACH) tells you how many times the purifier filters the entire room volume in one hour. For allergy and sinus relief, you want a minimum of two ACH, and ideally four ACH during peak allergy season. Most manufacturers list the maximum room size for one ACH, which means the air gets fully cleaned once per hour at the highest fan speed. That is the bare minimum.

To get four ACH, buy a purifier rated for a room twice the size of your actual room. If your bedroom is 200 square feet, buy a purifier rated for at least 400 square feet. This lets the purifier run at lower, quieter fan speeds while still cycling the air enough to keep allergen levels low. The Coway Mighty at 361 square feet is perfect for bedrooms up to 180 square feet with four ACH.

Ozone and ionizer safety

Some air purifiers include ionizers that charge particles in the air to make them stick to surfaces or filters. The problem is that ionizers can produce trace amounts of ozone as a byproduct, and ozone is a known respiratory irritant. For people with asthma, sinus problems, or sensitive airways, ozone exposure can worsen the very symptoms you bought the purifier to fix.

The Coway Mighty has an ionizer, but it can be turned off. The Medify MA-40 also has an optional ionizer. The LEVOIT Core 400S and Blueair Blue Pure 311i Max do not produce ozone at all. If you have respiratory sensitivities, I recommend choosing a purifier without an ionizer or disabling the ionizer feature if your unit has one. Look for CARB certification, which confirms the unit meets California’s strict ozone emission standards.

Filter replacement costs

The purchase price is only part of the cost equation. Over two to three years, filter replacements can exceed the original price of the purifier. Here is a rough annual cost breakdown for the models in our review. The Coway Mighty costs about $50 to $70 per year in filters (HEPA annually, carbon every six months). The LEVOIT units run $60 to $80 per year. The Blueair runs about $50 to $55 per year thanks to the washable pre-filter extending main filter life. The Medify MA-40 runs $60 to $80 per year. The PuroAir 400 can run higher at $70 to $100 per year depending on usage.

Units with washable pre-filters, like the LEVOIT Vital 200S and Blueair 311i Max, offer the best long-term value because the pre-filter catches large particles that would otherwise shorten the main filter’s lifespan. I strongly recommend checking replacement filter prices before buying any air purifier.

Certifications to look for

Several third-party certifications help you separate effective purifiers from marketing hype. AHAM VERIFIDE means the Association of Home Appliance Manufacturers independently tested and confirmed the CADR claims. CARB Compliant means the unit meets California Air Resources Board ozone emission standards. Energy Star certification means the unit meets energy efficiency guidelines, which matters if you plan to run it 24 hours a day. ETL Listed means the unit passed electrical safety testing. The Asthma and Allergy Friendly certification from the Asthma and Allergy Foundation of America is the highest bar, indicating the purifier has been tested specifically for allergen removal in realistic home conditions.

Noise levels and sleep mode

If you plan to run your air purifier in a bedroom, noise level should be a top consideration. Look for units with sleep mode noise levels under 30 decibels. The Blueair Blue Pure 311i Max at 23 dB and the LEVOIT Core 400S at 24 dB are the quietest in our review. For reference, 30 dB is roughly the sound of soft whispering, while 50 dB is comparable to moderate rainfall. Anything above 55 dB will be noticeable in a quiet bedroom and may disturb light sleepers.
