Living with mold isn't just unpleasant; it can negatively impact your household's air quality and overall comfort. Fortunately, the best air purifiers for mold can help reduce your exposure to airborne mold spores before they spread throughout your home. The best mold air purifiers feature true HEPA filtration, capable of capturing up to 99.97% of airborne particles as small as 0.3 microns. Since mold spores typically range from roughly 1 to 40 microns in size, HEPA filtration is highly effective at trapping them before they reach your lungs. Filtration performance is only part of the equation, though. Many of the best air purifiers for mold also include features like Wi-Fi connectivity, app control, and real-time air quality sensors that help automate day-to-day operation. While these extras aren't strictly necessary, they can make it easier to monitor air quality, adjust settings remotely, and keep the purifier running consistently in the background.
We've tested over 40 air purifiers, and below are our recommendations for the best air purifiers for mold spores. If you're looking for other product recommendations, check out our picks for the best air purifiers, the best air purifiers for dust, and the best air purifiers for allergies. Of course, if you're consistently dealing with mold, you'll need to invest in more than a household air purifier and address the root cause. If the problem is humidity, you can check out our recommendations for the best dehumidifiers.
We buy and independently test air purifiers with no manufacturer samples, sponsorships, or pre-approved talking points. Each unit goes through the same standardized test bench, and the results are validated by multiple teams before being published on our website, so you can accurately compare them side by side.
This is all supported by readers like you, through paid memberships and your purchases through our links.

Best Air Purifier For Mold
Particle Filtration Rate8.6Filtration Layers5 StageNoise @ Highest Fan Speed63.2dBANoise @ Lowest Fan Speed32.3dBASee all our test resultsRecommended Room Size @ Max Fan Speed46.8 m² (504 ft²)The NuWave OxyPure is the best air purifier for mold that we've tested, especially if you need something powerful enough to handle larger spaces. Thanks to its high clean air delivery rate (CADR), it can clean the air efficiently in rooms exceeding 500 ft² (46.5 m²), helping reduce airborne mold spores more quickly and maintain better air quality over time. Its multi-stage filtration system is particularly well-suited for mold concerns, combining washable pre-filters, reusable Bio-Guard filters designed to trap mold spores, and a HEPA filter capable of capturing particles far smaller than the typical size of airborne mold. Most of the filtration system is washable and rated to last up to 20 years, with only the HEPA and activated carbon filter requiring yearly replacement, which helps keep long-term maintenance costs relatively low despite the high upfront price.
Another advantage of the OxyPure is that it maintains strong air-cleaning performance even at quieter fan speeds. This makes it easier to run continuously in bedrooms or living areas without the constant loud fan noise that often comes with high-capacity purifiers. At lower settings, it's still capable of handling airborne contaminants in most average-sized rooms, while its highest setting provides enough airflow to tackle larger, open-concept spaces more effectively. On top of that, the purifier includes plenty of convenience features, including Wi-Fi connectivity, app controls through the NuWave Connect companion app, and a built-in particle sensor that provides a real-time look at your home's air quality. That said, this is a genuinely large device, so you will want to consider less bulky options if you are short on space.

Best Upper Mid-Range Air Purifier For Mold
Particle Filtration Rate9.1Filtration Layers4 StageNoise @ Highest Fan Speed58.2dBANoise @ Lowest Fan Speed31.2dBASee all our test resultsRecommended Room Size @ Max Fan Speed62.2 m² (670 ft²)For those who don't need the NuWave OxyPure's reusable filter system, the Blueair Blue Signature Large is an excellent alternative for tackling mold spores in larger spaces. Its exceptionally high clean air delivery rate allows it to remove airborne mold spores quickly, making it a great choice for damp basements, large living rooms, or other areas where mold is more likely to become an issue. It also maintains strong filtration performance at quieter fan speeds, so you can leave it running continuously without creating much background noise. Wi-Fi connectivity lets you monitor air quality and adjust settings remotely through the Blueair companion app, while its furniture-inspired design helps it blend into your home more naturally than a typical air purifier.
That said, unlike the NuWave, the Blueair relies on its HEPASilent ionization system to achieve its performance, and this feature can't be disabled. While the system is certified to produce ozone within accepted safety limits, it may still be a concern if you or your pets are particularly sensitive to ozone. It also has a fairly wide footprint despite its lower profile, so it isn't the easiest purifier to fit into tighter spaces. At its quietest setting, it's barely louder than a whisper, while its highest fan speed is about as loud as a normal conversation.

Best Mid-Range Air Purifier For Mold
Particle Filtration Rate8.0Filtration Layers3 StageNoise @ Highest Fan Speed61.3dBANoise @ Lowest Fan Speed33.6dBASee all our test resultsRecommended Room Size @ Max Fan Speed35.3 m² (380 ft²)The Coway Airmega 200M is worth a look if you want an air purifier that handles mold spores reliably without breaking the bank. This mid-range option foregoes the Wi-Fi features found on the Blueair Blue Signature Large, meaning you can't remotely adjust fan speed or check air quality estimates on the fly. It does, however, include a particle sensor that automatically adjusts fan speed based on current air quality. At its highest fan speed, it can effectively clean spaces up to roughly 380 ft² (35.3 m²), making it a good fit for larger bedrooms, living rooms, or medium-sized basements, though you may need a second unit for especially large open-concept spaces.
On the noise front, its low-noise filtration performance trails both the Blueair and the NuWave OxyPure. At quieter settings, it handles smaller rooms up to 163 ft² (15.2 m²) well enough, but tackling larger spaces means pushing the fan closer to its max, where noise climbs to roughly 61.3 dBA, comparable to a normal conversation in the same room. On the plus side, it's shorter and thinner than the NuWave OxyPure, making it easier to tuck into tighter spaces. One thing to note is that the Coway comes equipped with an ionizer. These systems work by giving airborne pollutants a negative charge, causing them to clump together and fall out of the air, where they can be cleaned up later. The trade-off is that ionizers produce ozone as a byproduct, which can irritate the lungs with prolonged exposure. It's worth turning the feature off if that's a concern for your household.

Best Budget Air Purifier For Mold
Particle Filtration Rate6.0Filtration Layers3 StageNoise @ Highest Fan Speed54.7dBANoise @ Lowest Fan Speed33.6dBASee all our test resultsRecommended Room Size @ Max Fan Speed13.2 m² (142 ft²)If you want a budget-friendly, compact air purifier for dealing with mold, the Levoit Core 200S is worth a look. While its main filter technically isn't HEPA-certified, its real-world filtration performance is still sufficient to trap particles like mold spores effectively. It can't compete with a full-size unit like the Coway Airmega 200M in terms of overall air-cleaning power, but it still performs well in smaller spaces up to roughly 142 ft² (13.2 m²), making it a good fit for bedrooms, dorm rooms, home offices, or smaller apartments. It simply lacks the airflow needed to clean the air efficiently in larger living rooms or open-concept spaces.
A big upside is that this model is fairly unobtrusive noise-wise. Even at its highest fan speed, it only reaches around 54.7 dBA, roughly comparable to the sound of a household refrigerator running nearby. Its low-noise air-cleaning performance is fairly limited, however, so at quieter fan settings it struggles to clean the air effectively outside of very small rooms, and you'll need to run it at higher fan speeds to get the best performance. One advantage over the Coway is its built-in Wi-Fi, which lets you run the device while you're away from home, set operating schedules, and receive filter replacement reminders. Unfortunately, unlike the Coway, it lacks a built-in particle sensor that would allow it to automatically adjust fan speed on its own, which can be inconvenient if your home's air quality changes overnight.
