The 4 Best Air Purifiers For Dust - Spring 2025

The Honeywell HPA300 is the best air purifier for dust we've tested. This unit provides great overall performance, as it has a two-stage filtration system that includes a carbon pre-filter sheet and a trio of separate HEPA filters, resulting in excellent particle filtration. You'll need to swap out the carbon filter every three months and the HEPA filters every year, which is fairly standard for household air purifiers. Unfortunately, this unit is quite large and gets pretty loud at higher fan speeds. It's also worth noting that this is a pretty basic machine, lacking features like air quality sensors and Wi-Fi connectivity.

If you're willing to spend more in exchange for a broader array of convenience features, including an app that allows for remote control, consider the Levoit Core 600S. Just note that it doesn't work quite as fast in clearing the air of particulate matter compared to the Honeywell.

Check out the Levoit Core 300 for a budget-friendly solution to excess dust. This air purifier has a much lower clean air delivery rate than the Honeywell HPA300, so it works more slowly, especially in larger spaces. That said, it still offers excellent overall filtration as long as you keep its fan on a higher speed setting. It's also cheaper, smaller, and much quieter, so it won't be as disruptive in a living room or bedroom. Like the Honeywell, this air purifier is a simple device, so you won't find WI-FI connectivity or built-in particle sensors, but if you're looking for good filtration at a price that won't break the bank, it's a solid pick.

If you want to customize its performance, you'll be happy to hear that this machine is compatible with specialized Levoit filters meant to capture various types of allergens. You can choose between the 4-Stage Smoke Remover filter, the 3-Stage Toxin Absorber filter, and the 3-Stage Pet Allergy filter. While we haven't tested these filters yet, we expect them to perform similarly.

If you want a compact air purifier for dealing with dust, the Levoit Core 200S is a great choice. While it can't compete with a full-size unit like the Honeywell HPA300 in terms of clean air delivery rate and has a main filter that isn't HEPA-rated, it still delivers impressive overall particle filtration, especially given its compact size. This makes it a good option for bedrooms, offices, dorms, and other small spaces. It has Wi-Fi connectivity and access to the VeSync companion app, allowing you to run the device while you're away from home, set operating schedules, and even give it voice commands through Amazon Alexa or Google Assistant. You can also set up reminders to replace its filters, which you'll need to do every six to eight months.

Like the other options listed here, it lacks a built-in particle sensor that would allow it to adjust its fan speed automatically depending on real-time air quality.

If you're looking for an air purifier to deal with dust and don't mind working with your hands, you could also build your own Corsi-Rosenthal Box. We built ours by following this guide, which uses a set of 3M Filtrete MERV 13 air filters built around a Lasko 20-inch box fan. This DIY solution takes all the benefits and drawbacks of the Honeywell HPA300 to the extreme: it's even bigger and louder than the already cumbersome Honeywell, but it also offers outstanding particle filtration and a sky-high clean air delivery rate. These factors make it a good option for big areas where noise and aesthetics are of minimal concern, like a workshop or an unfinished basement. Unfortunately, operating costs for a Corsi-Rosenthal box can be a little high, as you'll need to swap out all four filters once they've hit the end of their useful lifespan.

Some users have iterated on this basic design by swapping out the large box fan for multiple PC cooling fans, resulting in quieter operation and lower power consumption. However, we haven't built or tested a Corsi-Rosenthal Box using this design yet.
