Mold is an obvious health risk in any home, but investing in an air purifier can help limit your exposure. The best among them will offer HEPA-level filtration, which can trap up to 99.97% of airborne particles down to 0.3 microns in diameter. Beyond that, you may want to look for features that make an air purifier easier and more convenient to use. There's no shortage of units on the market with quality-of-life features like Wi-Fi connectivity and built-in particle sensors. These features aren't strictly necessary, but they can increase efficiency, allow you to control the machine remotely, and, more generally, give you peace of mind that your air purifier is doing its job by helping to decrease mold in your home.
We've tested over 25 units, and below are our recommendations for the best air purifiers to trap 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 take a look at our recommendations for the best dehumidifiers.
We've independently tested over 25 air purifiers, purchasing each one ourselves like the average consumer would: no cherry-picked samples or talking points from manufacturers. 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.

Best Air Purifier For Mold
Particle Filtration Rate8.6Measured PM1.0 CADR548 m³/hr (323 CFM)See all our test resultsFiltration Layers5 StageThe NuWave OxyPure is the best air purifier for mold that we've tested. This unit's main selling point is its multi-stage filtration system that uses washable filters. This system comprises a stainless steel mesh pre-filter that can easily trap dust or clumps of hair, two 'Bio-Guard' filters to trap mold, viruses, and bacteria, an ozone filter, and a combination HEPA/pellet-type activated carbon filter. Except for the latter, which needs replacing every year, these filters have a 20-year lifespan, so while the unit's upfront cost is rather high, you won't have to spend a fortune on replacement filters. As expected for something this expensive, the NuWave is jam-packed with features. You can operate it from your smartphone using the NuWave Connect companion app, which leverages its built-in particle counter to give you an overview of ambient air quality in your home.
Actual air filtration is very good; the OxyPure provides a very high clean air delivery rate (CADR), making it an efficient option for larger rooms. It also does a fantastic job of trapping relatively large particles like mold spores. That said, there's no getting around the fact that this machine is very pricey. If you don't need any of the NuWave model's fancier features, you might be better off purchasing multiple instances of a cheaper model.

Best Upper Mid-Range Air Purifier For Mold
Particle Filtration Rate8.8Measured PM1.0 CADR617 m³/hr (363 CFM)See all our test resultsFiltration Layers3 StageWhile the Levoit Core 600S lacks the NuWave OxyPure's additional 'BioGuard' and ozone filter, it's still absolutely worth a look if you're looking for something a little cheaper. Its three-stage filtration system is easily capable of handling large airborne particles like mold spores, and at its max fan speed, its excellent CADR makes it a suitable option for use in larger basements. It's also Wi-Fi enabled, so you can adjust its fan speed setting or see a real-time estimate of the current air quality regardless of where you are.
While this unit is a little more compact than the bulky NuWave, it's still a somewhat large unit, which can make it a bit of a pain to place in rooms where free space is at a premium. It's also a little louder than the NuWave when both units are set to their lowest fan speed settings.

Best Mid-Range Air Purifier For Mold
Particle Filtration Rate8.0Measured PM1.0 CADR414 m³/hr (243 CFM)See all our test resultsFiltration Layers3 StageCheck out the Coway Airmega 200M if you're looking for an air purifier that can easily deal with mold spores without totally breaking the bank. This mid-range option lacks the Levoit Core 600S' Wi-Fi-enabled features, so you can't do things like change its fan speed setting or view a real-time estimate of air quality from afar, though it does have a particle sensor that allows it to adjust its fan speed setting automatically. Its CADR is more than sufficient for larger rooms, though it does fall short of the Levoit, and it may require a second unit for clearing the air in especially large open-concept living spaces or basements. In terms of footprint, it's shorter and thinner than either the pricier Levoit or NuWave OxyPure, making it a little easier to fit in tighter spaces.
Unlike some of the other options on this list, the Coway is equipped with an ionizer. These systems are intended to reduce airborne pollutants by imparting them with a negative charge, causing them to clump together and fall out of the air, where they can be cleaned up later. However, these systems produce ozone as an operating byproduct, which can irritate the lungs through prolonged exposure, so you might want to turn the system off if that's a major concern.

Best Budget Air Purifier For Mold
Particle Filtration Rate6.0Measured PM1.0 CADR154 m³/hr (91 CFM)See all our test resultsFiltration Layers3 StageIf you want a budget-friendly, compact air purifier for dealing with mold, the Levoit Core 200S is worth a look. While it can't compete with a full-size unit like the Coway Airmega 200M in terms of clean air delivery rate, it still offers a solid performance and will do quite well in smaller spaces, like a bedroom or office. Its main filter technically isn't HEPA-certified, but its filtration performance is still sufficient to trap particles like mold spores. One advantage over the Coway is its integrated Wi-Fi connectivity, which allows you to run the device while you're away from home, set operating schedules, and set up reminders to replace its filters. Unfortunately, unlike the Coway, it lacks a built-in particle sensor that would allow it to adjust its fan speed automatically depending on real-time air quality.

Honeywell HPA300:
The Honeywell HPA300 is a full-sized household air purifier with HEPA filtration. It has a higher clean air delivery rate than the Coway Airmega 200M, but it's much louder and lacks a built-in particle sensor.

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.

Coway Airmega AP-1512HH Mighty:
The Coway Airmega AP-1512HH Mighty is a well-rounded air purifier priced similarly to the Coway Airmega 200M. It offers a similar overall feature set along with a built-in ionizer, but its particle filtration performance and CADR are both slightly inferior to the 200M.

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 a little lower than that of the Coway, making it a little less suited to larger areas.
