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 25 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 Rate8.8Filtration Layers3 StageNoise @ Highest Fan Speed61.2dBANoise @ Lowest Fan Speed33.7dBASee all our test resultsRecommended Room Size @ Max Fan Speed52.7 m² (567 ft²)For those who don't need all the extras the NuWave OxyPure brings to the table, the Levoit Core 600S offers capable mold filtration at a more accessible price. Its three-stage filtration system handles large airborne particles like mold spores with ease, and its strong overall air-cleaning performance makes it a solid choice for spaces up to 567 ft² (52.7 m²). That gives it enough coverage for larger living rooms, open-concept spaces, or damp basements where musty smells and recurring moisture issues are more common. It also delivers impressive air-cleaning performance at quieter fan speeds, making it a great fit for bedrooms or other spaces where you want to keep noise levels lower while still filtering the air effectively. Wi-Fi connectivity makes it easy to adjust settings or check real-time air quality estimates without needing to walk over to the unit, rounding out a well-equipped package for the price.
While more compact than the NuWave, this unit is still a fairly large purifier, which can make placement tricky in tighter spaces. It also runs a little louder than the NuWave at its lowest fan speed, though its quietest setting sits around 33.7 dBA, quiet enough to blend into most bedrooms or offices. At its highest fan speed, noise levels climb to roughly 61.2 dBA, about as loud as a running dishwasher or a normal conversation nearby.

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 Levoit Core 600S, 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 Levoit 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 both the Levoit and 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 tradeoff 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.

Corsi-Rosenthal Box:
A Corsi-Rosenthal Box is a homemade air purifier made from a quartet of 3M Filtrete air filters and a box fan; we built our own using this guide. This setup delivers good air filtration performance but is also loud and very bulky, making it best suited to unfinished basements or garages.

Levoit Vital 200S:
The Levoit Vital 200S is a good alternative to the Coway Airmega 200M if Wi-Fi connectivity is a must-have feature. That said, its max CADR is slightly lower than the Coway's, making it less suited to larger areas.
