This has been a year in which we’ve spent a lot of time thinking about viruses, allergens, and air quality—and most of us have spent an unusual amount of time at home, wondering how clean our house’s air actually is. As the year draws to a close, perhaps it’s time to enhance your air quality by taking advantage of a Cyber Monday air purifier deal.

Air purifiers come in all shapes and sizes, but the one thing they all have in common is that they’re designed to reduce the amount of contaminants like dust, smoke, pet dander, organic compounds, allergens and bacteria. They might do that in a variety of ways; most feature one or more mechanical filters. HEPA (high-efficiency particulate air) is considered the gold standard in filtration, designed to remove 99.97 percent of dust, pollen, mold and bacteria, plus all airborne particles 0.3 microns or larger. But there are other kinds of air purifiers as well. Ionic models generate an ionic field that pulls particulates out of the air. (Beware, though, that some of these devices create ozone, which has its own health concerns.)

There are other considerations to keep in mind as well, such as aesthetics, how much air they move her hour and the lifetime cost when you consider replacement filters. If this is your first time buying an air purifier, you can read all about how to choose the right air purifier for your home.

Many retailers and brands are dropping prices with Cyber Monday air purifier deals today and for the next few days. Because air purifiers are a big-ticket item that don’t often go on sale at deep discounts, these will probably sell out fast, so you might want to move quickly.

Is Cyber Monday a good time to save money on air purifiers?

Yes, Cyber Monday—which is happening right now—is an online sale that features a lot of consumer electronics, including both big-ticket and less expensive products. Many air purifiers cost several hundred dollars and certainly qualify as big-ticket items; you can find a lot of deals on air purifiers from major brands like Molekule, Dyson, Morpilot, Samsung, Conway and more.

Do air purifiers actually work?

They do, but not everyone necessarily needs one. Most air purifiers use filters to trap particles like dust, smoke, pet dander, and mold, while others rely on ionic fields to “zap” particulates out of the air. The best air purifiers are so effective that they can remove over 99% of pollutants and contaminants from indoor air—but it’s important to change the filters regularly or your air purifier won’t be as effective.

What is a HEPA filter?

HEPA stands for High Efficiency Particulate Air and designates a kind of filter that traps 99.97 percent of particles that are 0.3 microns or larger. HEPA filters undergo a certification process, which assures you of a standard level of quality for any HEPA air purifier.
