The main things to consider when purchasing an air purifier are the purifier’s range, its noise level, and ozone concerns. Some air purifiers produce ozone (either in low or higher amounts depending on its intended function) as a deodorizing method.
While effective, ozone can irritate the respiratory tract and causes breathing difficulties in some people. People with breathing disorders such as asthma or COPD should avoid purifiers that produce ozone and instead choose purifiers that use carbon filters to trap odors. Air purifiers and filters are perfect for indoor allergy sufferers.
Best Air Purifiers in 2022
Common household allergies include dust and mold, which most air purifiers are designed to handle. These purifiers also handle pet dander (and the resulting unpleasant odors), and cigarette smoke. Some also come with germ-killing features, such as UV light, for an overall healthier home.

The Details
This air filter and purifier are available for $39.95 with Prime on Amazon. It has a permanent dust collector rode that can be cleaned with a damp cloth and a washable charcoal filter. This filter uses ions rather than mechanical filters: it releases negative ions into the air that then attach to unwanted particles like germs and allergens and make them too heavy to remain airborne.

Conclusions
The air purifier that probably jumped out at you was the $40 unit coming in at #2 on this list. It’s an amazing little appliance for its price and would be great for anyone looking mainly for better smells and fewer airborne pathogens. However, for people with allergies, a purifier with a mechanical filter (such as the True HEPA filter used in most of the purifiers listed) is a superior choice.
So, if you want an air purifier with a mechanical filter, which is your best option? Well, note that only #8 on the list comes with a remote. Not all of these units come with dimming options, which is something to consider for a bedroom air purifier. The Honeywell 50250-S is the only purifier to make the list that has a long-life filter, while the Honeywell HFD-120-Q actually has permanent filters.
Before buying an air purifier, check out the price of the replacement filters–for instance, the Winix Plasmawave WAC5500 replacement filter costs $64.99. That’s a filter you’ll be buying about once a year for the life of the product. Meanwhile, the Honeywell HPA300 has a value pack option that costs notably less.
Whether you want a cleaner, fresher home (or business, as the #10 air purifier is ideal for) or a safe haven from allergies, a variety of air purifiers may work for you. The minimalist might not want the germ-fighting power of the UV light technology, but that same technology might come in handy for a family with young children. The air purifiers on this list have been shown to be worth the investment.
Great list! Air purifiers should be a staple in your home. Thanks for sharing your information.
