Air purifiers are an essentially utility these days. They not only manage to thoroughly clean the air of all pollutants like viruses and bacteria, but they also remove odors caused by cooking, pets, or smoking. The Honeywell HPA300 (opens in new tab) is our pick for its ability to scrub 99.97% of all allergens from the air, ensuring you're always breathing clean air in your house.

The Honeywell HPA300 is a standout product that does a fantastic job getting rid of allergens and odors. The air purifier is particularly suited for large rooms, and can effectively clean rooms up to 465 square feet, recycling the air up to five times in an hour. It is quite heavy at 17 pounds, but it comes with a handle on the size that lets you move it between rooms should you wish to do so.

The HPA300 comes with filters: a pre-filter with activated carbon that absorbs gases, odors, and other large particles, and a high-efficiency particulate air (HEPA) filter for all pollutants. The air purifier cleans 99.97% of all airborne particles 0.3 microns or larger, including viruses, bacteria, pollen, pet hair, mold spores, and more. It is also great at eliminating odors. You'll have to change the pre-filter once every three to four months, and the HEPA filter once a year.

There are four cleaning modes to choose from — germ, allergen, general clean, and turbo — and there are easy controls at the top that let you switch between modes. You also get LED indicators for filter replacement, and there's a timer feature that lets you choose how long you want the air purifier to run.

Leave it to Dyson to turn one of its tower fans into an air purifier. The Pure Cool TP01 features a HEPA filter in the base that eliminates all pollutants from the air, and that clean air is pushed outward. With Dyson's Air Multiplier tech pushing 77 gallons of air every second, this is the one to get if you want a tower fan that's also an air purifier.

It isn't missing out on any features either — you get an activated carbon layer that reduces odors and gases, and because the TP01 is also a fan, you can choose from a range of oscillation and fan settings. The oscillation feature ensures clean air is delivered across all parts of the room. There's also a magnetized remote that attaches to the side of the air purifier, making it harder to lose.
