If you’re considering purchasing an air purifier, you might feel overwhelmed by all of the choices out there. It can be tough to navigate the market, especially with so many companies claiming to have the best product. Below, we’ll take a look at how air purifiers work and what factors might mean the most to you. One thing that many folks tend to do is overestimate the abilities of any air purifier. Even the highest-quality air purifiers are just that–air purifiers. They can’t replace vacuuming or sweeping. They can’t remove dust, dirt, and other allergens and pollutants from surfaces, though they can help keep some of those particles from settling on surfaces.
In a nutshell, air purifiers clean the air by removing various pollutants like dust, pet dander, and odors. The motor powers a fan, creating a vacuum that draws air in. Next, the air is passed through one or more filters. The filters capture pollutants, and the clean air is sent out through an exhaust port. There are even models now that employ UV lights and/or electronic means of cleaning the air, either with or without filters.
The first thing you should do is decide on your max budget. There are models that come in at around $50 and some that can exceed $1,000. While you certainly are bound to find superior performance at the higher end, there are also some excellent models available on the lower end of the price spectrum, though $200 should probably be as low as you go since the cheapest models are too often less effective than advertised and tend to be poorly constructed. You might find exceptions to this rule of thumb if you have less than 500 square feet to cover, don’t plan to run the unit around the clock, and only have minimally “dirty” air.

Next, you need to know how large an area you want to cover. There are models designed to cover anywhere from a few hundred square feet to over 1,000 square feet. Models built to handle the largest areas are usually the most expensive, so you might find it more cost effective to go with two or more smaller models if you want to clean your whole home. Unless you have a completely wide-open floor plan, multiple units will likely be more effective since you’ll be drawing in air from multiple points.
When it comes to filtration methods, your needs should guide your decision. HEPA filters are rated as being able to remove at least 99.97% of particles 0.3 microns or larger. This includes most airborne allergens and dust, including most pet dander. If pet allergies are a significant issue for you or anyone in your household, a filter rated for 0.2 microns or smaller is certain to handle all pet dander, since pet dander typically runs 2.5 to 3 microns. Some air purifiers use an ionization process to clean air, alone or in addition to a more traditional mechanical filter. Incoming particles are ionized, creating a charge. Metal plates inside the unit are oppositely charged, thereby attracting these ionized particles. If you opt for one of these models, you must clean the metal plates frequently, as they lose effectiveness much quicker than traditional filters. A few models employ a UV light in addition to a filter. The UV light emits ozone into the room, which reacts with gases and odors in the air and breaks them down chemically. There’s not a lot of hard evidence to suggest true superiority of ionizing or UV models over quality models with mechanical filters, meaning these “fancier” models might not be worth the extra cost.
