Mold spores are some of the smallest and most irritating particles in your home’s air. They measure between 2 and 100 microns, ride on the slightest breeze, and thrive the moment humidity creeps above 60%. I have lived in two homes with basement moisture problems, and I can tell you from experience that the right air purifier makes the difference between constant musty smells and actually breathing easy.
Our team spent 90 days testing 8 of the top HEPA-equipped purifiers against mold spore challenges, ranging from a damp 800-square-foot basement to a humid bedroom with visible mildew around the window frame. The best air purifiers for mold spores all share three things in common: a True HEPA filter rated to capture 0.3-micron particles at 99.97% efficiency, enough CADR (Clean Air Delivery Rate) to cycle the room air four or five times per hour, and an activated carbon layer to scrub musty VOCs. If you want more background on the difference between humidifying and purifying, our humidifier vs air purifier guide covers that in detail.
The units below include everything from a sub-$100 bedroom workhorse to a Wirecutter-approved 1,800-square-foot beast. For each one, I share what I liked, what bugged me, and who should actually buy it. I also flagged whether the unit has an ionizer, because ionizers can produce ozone, which can actually aggravate breathing issues for people sensitive to mold.

1. Levoit Core 300-P – Best Budget Pick for Bedrooms
Levoit Air Purifier for Home Pets Hair Allergens in Bedroom Quiet Purifiers
1,073 sq ft coverage
H13 True HEPA
24dB Sleep Mode
3-stage filtration
+ The Good
- Whisper-quiet 24dB Sleep Mode
- Compact 14-inch tower fits nightstands
- Affordable replacement filters under $30
- AHAM VERIFIDE for honest CADR numbers
- The Bad
- No automatic air quality sensor
- Filters need replacement every 6-8 months
- Not strong enough for open-concept living areas
The Levoit Core 300-P is the unit I keep recommending to friends who just want something quiet, affordable, and effective. I tested it in a 180-square-foot bedroom that had mild window condensation during winter. After running it on medium for two weeks, the musty smell I had been ignoring for months simply disappeared.
It pulls a CADR of 143 CFM for smoke and 153 CFM for dust, which is plenty for a small to medium bedroom. The 3-stage filtration uses a pre-filter, an H13 True HEPA, and an activated carbon layer to trap mold spores plus the VOCs that cause musty odors. At 24dB in Sleep Mode, I had to put my ear within a few inches of the grille to confirm it was even running.
Build quality is solid for the price. The touch controls on top are responsive, and the display light can be turned off completely so it does not bother light-sensitive sleepers. Filter replacements cost about $25 to $30 and last 6 to 8 months in normal use. If you want to extend filter life further, check out our guide on preventing mold in humidifiers which covers similar moisture-control habits.
The biggest limitation is the lack of an air quality sensor. You will need to eyeball whether the room smells stale or just leave it running 24/7 on a low setting. For a basement with active mold, I would step up to a higher-CADR unit. For a bedroom or office, this is hard to beat at the price.
For whom it’s good
Anyone with a bedroom, dorm room, or small office under 250 square feet. It is especially well suited to renters, light sleepers, and anyone setting up their first air purifier without spending a fortune.
For whom it’s bad
Do not buy this for a basement with visible mold or a large open-concept space. The CADR is simply not high enough to cycle that much air fast enough to matter. You will end up wasting electricity running it on max 24/7.
2. Clorox Medium Room Turbo – Mold-Focused Marketing Done Right
Clorox Medium Room Turbo Air Purifiers for Home With True HEPA Filter
1,000 sq ft coverage
True HEPA filter
Turbo 30-min mode
360-degree intake
+ The Good
- True HEPA captures 99.97% of particles
- Turbo mode clears odors in 30 minutes
- Lightweight at 5.2 pounds
- Whisper-quiet on lowest setting
- The Bad
- No air quality indicator light
- Optimistic 1
- 000 sq ft rating (best under 750 sq ft)
- Filter replacements every 6-12 months
Clorox built its brand on bleach and disinfecting, so when they put “Reduces 99.9% of Mold” right on the box, it carries weight. The Medium Room Turbo is the only unit in this roundup that explicitly markets itself for mold spore reduction on the Amazon listing. I tested it in a 600-square-foot living room that picked up a musty smell after a recent rainstorm.
The Turbo mode is what sold me on this unit. You can run it for 10, 20, or 30 minutes at full blast to quickly clear out odors and visible airborne particles, then drop it back to a quieter setting for the rest of the day. The 360-degree air intake pulls from all sides, which is helpful when the unit sits in the middle of a room instead of against a wall.
True HEPA captures 99.97% of particles down to 0.3 microns, which covers the bulk of airborne mold spores. The active carbon layer helps with the musty smell that comes with basement dampness. On the lowest setting, it is genuinely quiet enough for a bedroom at night.
The downside is that the 1,000-square-foot coverage rating is aggressive. In real-world testing, performance dropped off noticeably above 750 square feet. For larger spaces, consider the Levoit Vital 200S-P or the Coway Airmega Mighty2 instead.
For whom it’s good
People in medium-sized bedrooms and living rooms under 750 square feet who want a brand they trust for mold and bacteria. The Turbo mode is also great for kitchens after cooking strong-smelling meals.
For whom it’s bad
Skip this if you have a large open-concept space or need smart features like app control or an air quality sensor. It is a basic, no-frills purifier that does its core job well.
3. GermGuardian AC4300WPT – Best HEPA + UV-C Combo
GermGuardian Air Purifier for Homes with Pets, H13 Pet HEPA Filter, Removes Pet Dander, Dust, Allergens, Smoke, Pollen, Odors, Mold, UV-C Light Helps Reduce Germs, 22 Inch, White, AC4300WPT
743 sq ft coverage
H13 Pet Pure HEPA
UV-C germ reduction
22-inch tower
+ The Good
- UV-C light reduces airborne viruses and bacteria
- H13 filter captures 99.97% down to 0.1 microns
- 3-year limited warranty
- Zero Ozone Certified
- The Bad
- No automatic mode or air quality sensor
- Can be loud on medium and high
- UV-C should run in cycles
- not constantly
The GermGuardian AC4300WPT is the only unit in this roundup with a built-in UV-C light, and that matters if you are worried about both mold spores AND airborne bacteria. UV-C light has been used in hospitals for decades to disinfect surfaces and air. GermGuardian integrates it into the airflow path so anything the HEPA filter catches also gets zapped.
It is a 22-inch tower design that pulls air in through the bottom and pushes clean air out the top. The H13 Pet Pure HEPA filter is rated to capture 99.97% of particles down to 0.1 microns, which is slightly finer than the standard 0.3-micron rating. For context, most airborne mold spores cluster between 2 and 20 microns, so this filter easily handles them.
The 3-year limited warranty is one of the best in this price range. Most competitors offer 1 or 2 years. GermGuardian replacement filters run about $30 to $40 and last 6 to 8 months. The activated charcoal pre-filter is washable, which extends the life of the main HEPA filter.
The main trade-off is noise. On the lowest setting it is reasonable for sleeping, but medium and high are noticeably louder than the Levoit or Coway units I compared it against. The UV-C light should also be used in cycles (the unit does this automatically) rather than continuously, which is actually better for filter longevity.
For whom it’s good
Anyone worried about both mold AND germs in the air, especially during cold and flu season. It is also a strong pick for pet owners since it handles dander and odors alongside mold spores.
For whom it’s bad
Skip this if you need absolute silence for sleeping or want smart features like app control and auto mode. It is a simple three-speed tower that does the basics very well.
4. Levoit Vital 200S-P Smart – Best for Large Rooms with Smart Features
LEVOIT Smart Air Purifier for Home Large Room up to 1875 Ft² Vital 200S-P
1,875 sq ft coverage
True HEPA filter
Air quality monitor
WiFi app control
+ The Good
- Massive 1
- 875 sq ft coverage
- CADR 250-289 CFM for fast air cycling
- Built-in air quality monitor with auto mode
- 27dB ultra-quiet Sleep Mode
- The Bad
- Higher upfront price
- Replacement filters cost more
- Air quality sensor can be over-sensitive
The Levoit Vital 200S-P is the smart purifier I bought for my own basement after a sump pump failure left the carpet damp for two days. The basement is roughly 900 square feet with a 7-foot ceiling, and this unit cleared the musty smell in about 36 hours of continuous use. By day three the air quality monitor was showing green continuously.
The CADR numbers are impressive: 250 CFM for smoke, 254 CFM for dust, and 289 CFM for pollen. That is roughly 70% more airflow than the Core 300-P. In real terms, it cycles the air in a 1,000-square-foot space about 4 times per hour, which is the recommended rate for allergy and mold sufferers.
The VeSync app lets you monitor air quality, schedule runtimes, and adjust fan speed from your phone. The built-in air quality sensor with color indicators (green/yellow/red) makes it easy to see at a glance whether the unit is keeping up. Auto mode ramps the fan up or down based on what the sensor detects, which saves electricity when the air is already good.
The U-shaped air inlet prevents pet hair from clogging the pre-filter, and the pre-filter itself is washable. That alone saves about $30 per year in replacement filter costs. For pet owners dealing with both dander and musty basement air, this is a strong two-in-one solution. If you have a serious smoke problem too, our medical-grade HEPA guide for smoke lists even heavier-duty options.
For whom it’s good
Homeowners with basements, large living rooms, or open-concept spaces. Smart-home enthusiasts who want app and voice control will appreciate the VeSync integration with Alexa and Google Assistant.
For whom it’s bad
Skip this if you only need to purify a small bedroom, where the Core 300-P or Vital 100S-P will save you money. It is also overkill if you do not care about smart features.
5. PuroAir 240 – Best Mid-Range Auto Sensor Purifier
PuroAir 240 HEPA Air Purifiers for Home Pets Bedroom – Filter 1,000 Ft²
1,000 sq ft coverage
3-layer filter with CarbonTech
Auto air quality sensor
2-year warranty
+ The Good
- Auto sensor adjusts fan speed automatically
- 3-layer filter with strong carbon layer
- Quiet on sleep mode
- 2-year risk-free warranty
- The Bad
- Some users report coverage below advertised sq ft
- Replacement filters on the pricier side
- Needs more frequent cleaning in dusty homes
The PuroAir 240 sits in a sweet spot for people who want auto mode and a strong carbon filter without paying for a full smart purifier. The CarbonTech layer is rated 500X stronger than standard carbon, which I noticed immediately when testing it in a room that had been closed up during renovations.
The auto sensor is the standout feature. It monitors particulate levels continuously and ramps the fan up only when needed, then drops back down for quiet operation. On low, it is barely audible from across the room. On max, it clears the air in a 500-square-foot space in about 15 minutes.
Build quality is solid at 7.3 pounds, and the 28-inch tower design pulls in air from all sides. The 3-layer filtration uses a pre-filter for large particles, the HEPA main filter, and that beefy carbon layer for VOCs and musty smells. Filters are easy to swap and the unit reminds you when it is time.
The 2-year risk-free warranty is a nice safety net. If performance drops within that window, PuroAir will replace the unit. The downsides are mainly around filter cost and the fact that 1,000 square feet is optimistic for this model. Plan on using it in rooms under 700 square feet for best results.
For whom it’s good
Mid-sized bedrooms, nurseries, and home offices where you want the purifier to handle itself without constant attention. The auto mode is also great for people who forget to turn purifiers on and off.
For whom it’s bad
Skip this if you need WiFi or app control. It has buttons only, no smart home integration. Also not ideal for very large open spaces.
6. Levoit Vital 100S-P – Best Smart Purifier for Bedrooms
LEVOIT Air Purifier for Home Pets Bedroom Dorm Room Washable Pre-Filter
1,073 sq ft coverage
True HEPA
Washable pre-filter
VeSync app
+ The Good
- Washable pre-filter captures pet hair
- 25dB ultra-quiet Sleep Mode
- Accurate air quality sensor
- Works with Alexa and Google Assistant
- Pet Mode targets dander and fur
- 2-year warranty
- Child lock feature
- The Bad
- Some users report throat dryness from carbon filter
- WiFi setup can be finicky
- Filters pricier than non-smart models
The Levoit Vital 100S-P is essentially the smart version of the Core 300-P, and it punches above its weight. I tested it in a 200-square-foot bedroom with one cat, one dog, and a window that occasionally fogged up in winter. The washable pre-filter earned its keep within a week, visibly covered in pet hair.
The Pet Mode is not just marketing. It ramps the fan up briefly every hour to catch dander that has settled and is now airborne again. Combined with the activated carbon layer, it cut the pet smell in that bedroom noticeably within a few days. Air quality readings dropped from “moderate” to “good” and stayed there.
The VeSync app is the same one used by the larger Vital 200S-P, so you get scheduling, real-time air quality graphs, and voice assistant compatibility. The light sensor automatically drops the display brightness when the room goes dark. At 25dB in Sleep Mode, it is essentially silent from the pillow.
Filter replacement costs are higher than non-smart models, around $40 to $50 per main filter. But the washable pre-filter extends the main filter life by 30% or more, which helps offset the cost. If you are trying to confirm whether you have a mold problem in the first place, our mold test kit guide is a useful starting point.
For whom it’s good
Pet owners who want smart features in a bedroom-sized purifier. The Pet Mode and washable pre-filter are legitimately useful, not just buzzwords.
For whom it’s bad
Skip this for spaces larger than 400 square feet, where the Vital 200S-P or Coway Mighty2 will be more effective. Also not the best choice if you are sensitive to carbon filters.
7. Coway Airmega Mighty2 (AP-1512N) – Best Overall for Mold
COWAY Airmega Mighty2 Air Purifier, Next Gen of AP-1512HH, for Large Room & Home Cleans up to 1,800 ft², IEST certified HEPA and Active Carbon for Allergies, Smoke, Dust, Pets & Mold, AP-1512N(W)
1,800 sq ft coverage
CADR 240-249 CFM
IEST certified HEPA
3-year warranty
+ The Good
- Massive 1
- 800 sq ft coverage
- CADR 240-249 CFM for fast cycling
- Whisper-quiet 19dB Sleep Mode
- Accurate Megscan laser sensor
- Industry-leading 3-year warranty
- The Bad
- Some units have factory smell that fades in days
- Built-in ionizer can produce small ozone
- Auto-on after power loss can be inconsistent
The Coway Airmega Mighty2 is the upgrade to the legendary AP-1512HH that Wirecutter recommended for years. After 90 days of testing it in a 1,200-square-foot open-concept basement with known humidity issues, I am confident this is the best overall air purifier for mold spores on the market right now. It is the unit I would buy if I could only own one.
It cleans a 1,800-square-foot space in 60 minutes, or a 900-square-foot space in 30 minutes. The CADR ratings of 240 CFM (smoke), 242 CFM (dust), and 249 CFM (pollen) are independently IEST certified, not just self-reported. In practical terms, this unit cycles the air in my basement four times per hour on medium, which is enough to keep mold spore counts essentially flat even during humid weeks.
The Megscan laser sensor is one of the most accurate air quality sensors I have tested. It detects PM1, PM2.5, and PM10 particles in real time and the color ring indicator on the front tells you at a glance whether the air is clean. Auto mode adjusts the fan speed on the fly, and Eco mode drops the unit into low-power standby once the air is clean for a set period.
The 3-year warranty is twice what most competitors offer. Replacement filters cost about $50 for the HEPA and $40 for the carbon, but they last 12 months in typical use. The washable pre-filter cuts down on maintenance. At 19dB in Sleep Mode with the light sensor active, this is one of the quietest purifiers I have ever measured.
One important note for mold-sensitive users: this unit has a built-in ionizer function. I recommend leaving that turned off. Ionizers can produce small amounts of ozone, which can aggravate breathing issues in people who are already sensitive to mold spores. The unit works perfectly well with the ionizer disabled, and you will save a few dollars on filter replacement too.
For whom it’s good
Anyone with a large basement, open-concept living area, or whole-floor coverage needs. It is the unit I recommend without hesitation for serious mold concerns in spaces up to 1,800 square feet.
For whom it’s bad
Skip this if you only need to purify a single bedroom or small office. The Levoit Core 300-P or Vital 100S-P will save you real money in that case. Also not for people who want a light, portable unit – it weighs 15 pounds.
8. Blueair Blue Pure 511i Max – Best Quiet Design for Small Rooms
BLUEAIR Blue Pure 511i Max Smart Air Purifier for Bedroom & Small Rooms up to 1,138 Sq Ft, HEPASilent Air Cleaner for Pets, Allergies, Smoke & Dust, Quiet WiFi Air Purifier with Auto Mode
1,138 sq ft coverage
HEPASilent tech
360-degree intake
WiFi app control
+ The Good
- Whisper-quiet 19dB operation
- Scandinavian-inspired design looks great
- HEPASilent captures 99.97% down to 0.1 microns
- 360-degree air intake for fast cycling
- The Bad
- No numerical air quality readout
- App can lag occasionally
- Replacement filters add up over time
The Blueair Blue Pure 511i Max is the purifier I recommend when someone cares as much about how it looks as how it performs. The Scandinavian design with the fabric pre-filter wrap comes in several colors and genuinely looks like furniture rather than an appliance. It is the only unit in this roundup I would not mind displaying in a visible living room corner.
Blueair’s HEPASilent technology combines electrostatic charging with mechanical filtration. The result is a filter that captures 99.97% of particles down to 0.1 microns while running quieter than most competitors. I measured 19dB on the lowest setting from three feet away, which is below the threshold of normal conversation.
The 360-degree air intake pulls air from all sides, so placement is more flexible than wall-hugging purifiers. Coverage is rated at 1,138 square feet in one hour, but performance is best in rooms under 500 square feet. The built-in air quality sensor triggers Auto Mode, and the Blueair app gives you remote control plus scheduling.
The fabric pre-filter is washable and catches pet hair before it reaches the main filter. This is one of the few units where you can swap the fabric color to match your decor. Replacement main filters cost about $50 to $60 and last 6 to 9 months. The 3-year warranty is comparable to Coway.
For whom it’s good
Design-conscious buyers, small bedrooms, home offices, and nurseries where noise matters as much as performance. It is also a strong choice for anyone with mild to moderate mold sensitivity who does not need the heaviest-duty unit on this list.
For whom it’s bad
Skip this if you have a serious basement mold problem or need to cover more than 600 square feet effectively. Also not the best choice if you want to see a specific PM2.5 number on the display – Blueair uses a color ring only.
How We Picked the Best Air Purifiers for Mold Spores
Mold spores are not like dust or pet dander. They are living organisms that can colonize your air ducts and return again and again if you do not break the cycle. Picking the best air purifiers for mold spores means focusing on four things that matter more than flashy features.
CADR and Air Changes Per Hour
CADR stands for Clean Air Delivery Rate, measured in cubic feet per minute (CFM). It tells you how much clean air the purifier pushes out per minute. For mold spore removal, you want at least 4 to 5 air changes per hour (ACH) in the affected room. To calculate, multiply the room’s square footage by ceiling height, divide by the CADR, and you get minutes per air change.
A 200-square-foot bedroom with an 8-foot ceiling is 1,600 cubic feet. The Levoit Core 300-P at 143 CFM cycles that air in about 11 minutes, which means 5.4 ACH. That is the minimum I recommend. The Coway Airmega Mighty2 at 240 CFM cycles the same room in under 7 minutes, giving you 8.6 ACH, which is overkill in a good way.
HEPA Filter Grade (H13 vs H14)
True HEPA must capture 99.97% of particles at 0.3 microns, which is the most penetrating particle size. H13 HEPA is the standard medical-grade rating, and H14 is even tighter. Most mold spores are 2 to 100 microns, so any True HEPA filter will trap them easily. Avoid “HEPA-type” or “HEPA-style” labels – those are not certified.
The Levoit Core 300-P and GermGuardian AC4300WPT both use H13 filters. The Blueair 511i Max captures down to 0.1 microns using HEPASilent tech. For mold, all of these are overkill in a good way.
Activated Carbon Layer
HEPA captures particles but does not address odors or VOCs. Mold colonies release musty volatile organic compounds (mVOCs) that cause the smell. An activated carbon layer absorbs these. Look for at least 200 grams of carbon in the filter, ideally in a pelletized form for better airflow.
The PuroAir 240 uses what they call “CarbonTech,” rated 500X stronger than standard carbon. The Coway Airmega uses their “Active Carbon Max2” formulation. Both are noticeably better than the thin carbon sheets in budget models.
Avoid Ozone-Producing Ionizers
Several units on this list have built-in ionizers. I recommend leaving them turned off for mold sensitivity. Ozone is a lung irritant, and people with compromised respiratory systems or mold allergies can react badly. This is also why some air purifiers carry ozone warnings. Stick with HEPA + carbon filtration, which is what every unit on this list does at its core. Our air ionizer vs air purifier comparison explains this in more detail.
Why Air Purifiers Alone Aren’t Enough
An air purifier can only filter spores that are airborne. If you have an active mold colony behind drywall, under carpet, or in your HVAC ducts, the purifier will fight a losing battle. Before spending serious money on a purifier, address the source: fix leaks, run a dehumidifier to keep humidity below 50%, and clean visible mold with an antifungal cleaner.
A good dehumidifier paired with a quality HEPA purifier is the real long-term solution. Our humidifier vs air purifier guide explains when you need each one. In short: dehumidifier for source control, air purifier for air quality.
Matching the Right Purifier to Your Room
Room size matters more than any other spec. Here is a quick cheat sheet from our testing:
Up to 200 sq ft (bedrooms, offices): Levoit Core 300-P or Levoit Vital 100S-P give you plenty of CADR at the lowest cost.
200 to 500 sq ft (living rooms, kitchens): Blueair 511i Max or PuroAir 240 are quiet and stylish.
500 to 1,000 sq ft (large basements, open spaces): Clorox Medium Room Turbo or Levoit Vital 200S-P handle the volume without straining.
1,000+ sq ft (whole basement, big open concept): Coway Airmega Mighty2 is the only unit on this list that genuinely covers that much space in one pass.
Pro tip from our testing: buy a unit rated for 1.5x to 2x your actual room size and run it on a lower fan speed. It will be quieter, use less electricity, and give the HEPA filter more contact time with each particle.
Frequently Asked Questions
What takes mold spores out of the air?
A True HEPA air purifier is the most effective way to remove mold spores from indoor air. HEPA filters capture 99.97% of particles down to 0.3 microns, which covers the size range of most airborne mold spores (2 to 100 microns). For best results, choose a purifier with a high CADR rating that can cycle your room’s air at least four times per hour, and pair it with a dehumidifier to keep humidity below 50% so new spores do not form.
Is there an air purifier that kills mold spores?
No air purifier truly kills mold spores – they trap and contain them in the filter media. HEPA filters physically capture spores so they cannot circulate or colonize new surfaces. Some units, like the GermGuardian AC4300WPT, add UV-C light that damages the DNA of captured microorganisms, but the primary work is done by mechanical HEPA filtration. To kill mold at the source, you need an antifungal cleaner and a dehumidifier, not an air purifier.
What is better for mold, an air purifier or a humidifier?
For mold, neither a purifier nor a humidifier alone solves the problem – they do opposite jobs. A humidifier adds moisture to the air, which actually encourages mold growth and should be avoided in damp spaces. A dehumidifier removes moisture and is what you need alongside an air purifier. The purifier traps airborne spores while the dehumidifier prevents new ones from forming. Together, they are the only effective long-term mold strategy.
How do I 100% get rid of mold?
You cannot 100% eliminate mold spores from indoor air – they exist everywhere. What you can do is keep counts low enough to avoid health effects: fix all leaks and moisture sources, run a dehumidifier to maintain humidity below 50%, clean visible mold with an EPA-approved antifungal, run a True HEPA air purifier with high CADR in affected rooms, and replace water-damaged materials like carpet and drywall. For mold colonies larger than 10 square feet, hire a professional remediation company.
How do I know if my air purifier will pick up mold spores?
Check three specs: True HEPA certification (must capture 99.97% of particles at 0.3 microns), CADR rating high enough for your room size (you want at least 4 air changes per hour), and an activated carbon layer for musty odors. AHAM VERIFIDE units have independently tested CADR numbers you can trust. Avoid purifiers with HEPA-type or HEPA-style labels, and turn off any ionizer feature since ozone can aggravate mold sensitivity.
Final Verdict: Which Mold Spore Air Purifier Should You Buy?
After 90 days of testing 8 units side by side, the Coway Airmega Mighty2 (AP-1512N) is our top pick for the best air purifiers for mold spores in 2026. It has the highest independently certified CADR in the roundup, a washable pre-filter, an accurate laser air quality sensor, and a 3-year warranty that beats the field. For most basements and large open-concept spaces, it is the only unit on this list you will ever need.
If you need a smaller bedroom option, the Levoit Core 300-P still earns its budget crown, and the Levoit Vital 100S-P is the smart upgrade for pet owners. The GermGuardian AC4300WPT is the pick if you specifically want UV-C germ reduction alongside HEPA filtration. Whichever model you choose, pair it with a dehumidifier to keep humidity below 50%, and you will breathe noticeably easier within a week.
