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.

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, the best dehumidifiers for basements, and the best dehumidifiers for bedrooms.

Best Air Purifier For Mold
Particle Filtration Rate8.6Particle Concentration7.9Air Cleaning Rate405 m³/HourAverage Final 0.3 µm Concentration77 particles/LSee 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 instead of disposable 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 HEPA/activated carbon filter, 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. You can also use the app to set operating schedules or change the device's settings.
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 Budget Air Purifier For Mold
Particle Filtration Rate8.0Particle Concentration9.6Air Cleaning Rate268 m³/HourAverage Final 0.3 µm Concentration13 particles/LSee all our test resultsFiltration Layers3 StageCheck out the Levoit Vital 200s if you're looking for an air purifier that can easily deal with mold spores without totally breaking the bank. While its clean air delivery rate falls behind the NuWave, it's still well-suited to medium-sized rooms. Its filtration system has no trouble dealing with particles like mold spores, and it features a built-in particle sensor that allows it to change its fan speed depending on ambient air quality, so you won't have to babysit the device too much. You can check an estimate of live air quality using the VeSync companion app, too. Its main filter isn't HEPA-certified, but in terms of real-world performance, it's broadly similar to units that are.
As far as downsides go, the unit does have a slightly bulkier shape than the cylinder-shaped Levoit Core 400S, though it does lack the Vital 200S' washable pre-filter for trapping larger particles that would dirty the main filter. Still, the Core 400S is worth a look if it can be found for a lower price, as overall performance is pretty similar between the two units.

Best Compact Air Purifier For Mold
Particle Filtration Rate6.7Particle Concentration7.9Air Cleaning Rate99 m³/HourAverage Final 0.3 µm Concentration80 particles/LSee all our test resultsFiltration Layers3 StageIf you want a 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 Levoit Vital 200S 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 Winix model 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 Winix, 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 Levoit Vital 200S, 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 Levoit Vital 200S. 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 Levoit.
