The air inside your home can get stale — or worse, it can become permeated with dust, pollen, pet dander and various pollutants. And, of course, if it's allergy season or bitterly cold out, you probably don't want to open your windows. Out advice? You should consider getting an air purifier. You don't need to suffer from allergies or asthma to benefit. Besides removing indoor pollutants, air purifiers capture many airborne viral pathogens, meaning you're less likely to get sick. Experts often recommend that you have one in your bedroom. You should also consider another in a common area like the living room or kitchen (an air purifier is excellent for eliminating cooking smells). Below are shoppers' favorite models so you can make the best choice for your house.

$147 at Amazon

Right now, you can score this Veva air purifier for less than $150. Air purifiers are only designed to cover a certain range, the Environmental Protection Agency points out — getting more than one allows you coverage in different rooms at once. But you'll want to act fast, because this deal won't last long!

Shoppers find that big things come in small packages when it comes to the purifying power of the Veva. "Don’t let the compactness of this unit fool you! The Veva ProHEPA 9000 Air Purifier is absolutely the real deal," one owner exclaimed. "I noticed a major air improvement in the back rooms of my home within only the second day of use. Bravo, Veva!"

Pure Enrichment PureZone Air Purifier

$100$130Save $30

This beauty of a beast can trap over 99.97% of odors, smoke, dust and other allergens.

$100 at Amazon

It uses a three-stage filter to trap the nasty stuff — a pre-filter, an activated carbon filter and finally, a true HEPA filter. A built-in UV-C light provides an extra layer of sanitation. It’s energy-efficient, too, so your bill won’t suddenly skyrocket. Did we mention it has over 13,000 five-star reviews on Amazon?

Not surprisingly, the whisper-quiet gadget has plenty of fans among the snoring community. "Love the sleek appearance, easy operation and instructions," one shopper noted. "I can breathe much better too. Stopped my hubby from snoring at night and it's whisper quiet! I do love the fact that it blows air from the top and not the sides like most purifiers. This is a definite keeper. I love it!"

Coway Airmega AP-1512HH

Coway Airmega AP-1512HH True HEPA Air Purifier

$193$230Save $37

Designed for spaces up to 874 square feet, this little air purifier is perfect for use in a bedroom or smaller living room. 

$193 at Amazon

Coming in with over 18,000 five-star reviews on Amazon is the Coway Airmega AP-1512HH (aka the Coway Mighty). There is good reason for its popularity. Its four-stage filtration system can capture and reduce up to 99.97 percent of particles, which includes volatile organic compounds and odors in addition to the standard pollen and pollutants. The pre-filter is washable, while the True HEPA filter is replaceable. The LED glows different colors depending on the air quality, and the auto mode automatically optimizes the fan speed according to that quality level.

“This is incredible,” one shopper said. “How did I ever live without it before? The auto mode really works! We have an open-floor-plan 1600-square-foot home. The kitchen, living room, dining room, foyer and breakfast area are all open...We no longer come home to a house smelling like what we've been cooking.”

Coway Airmega 200M True HEPA Air Purifier

$197$230Save $33

Perfect for a home office or smaller space, this air purifier can keep you breathing easy even in the muggiest summer air. 

$197 at Walmart

If your aesthetic runs more retro than contemporary, you'll want to consider the Coway Airmega 200M. It has all of the same performance features as the Coway Airmega AP-1512HH, but the design isn't as slick and modern. The Airmega 200M can accommodate rooms up to 361 square feet, and it has a 4-stage filtration system and LEDs that indicate the indoor air quality.

"Absolutely obsessed with it already. Only have had for a few weeks, but have already seen a difference! I suffer from severe allergies, mainly from dust. The unit sits next to my chair when we watch TV. On Echo mode, it senses when the air quality is poor. When it was first plugged in, it ran almost constantly! Now, a few weeks later, it runs very occasionally. An improvement already! Very quiet. Love it. Highly recommend it!"

Coway Airmega 400(G) Smart Air Purifier

$600$749Save $149

You can rest now — your search for a whole-home air purifier is over. This beast can cover up to 1,560 square feet in just half an hour, reducing 99% of odor from a room. 

$600 at Amazon

For those with larger homes and open floor plans, we recommend the Coway Airmega 400. It works with rooms up to 1,560 square feet, and it cleans the air at least twice an hour even in the biggest spaces. The Max2 filter system, which combines both an activated carbon filter plus a True HEPA filter, is able to capture and reduce 99.97 percent of the minuscule particles that comprise dust, pollen, and harmful volatile compounds. This model features five fan modes and an LED ring that changes color depending on the air quality.

“I purchased this for the sole purpose of allergies. Starting the day after I turned it on, I have not sneezed one time and the allergies have basically gone away. I cannot believe how much better I feel. I honestly feel the difference in the air in my house,” wrote one shopper. “If it weren’t for the indicator lights, you wouldn’t even know it was running 99 percent of the time. On medium fan speed you can barely hear it, and on high speed, you can hear it but it’s much quieter than a standard fan running in the house.”

Those who equally value form and function are sure to love the Blueair Blue Pure 311. Its Scandinavian-modern good looks match its impressive performance. The Pure 311 is recommended for medium-sized rooms, which makes it ideal for many bedrooms, kitchens, and family rooms. It eliminates odors and removes 99.97 percent of airborne pollutants, including viruses and fine particles from wildfires. In addition, the fabric pre-filter cover is washable and is available in five colors (colors other than dark gray are sold separately).

“I bought this air purifier before taking on a home remodel/addition project in anticipation of increased dust,” said one reviewer. “In addition, I have cats and dogs in the house, so figured it would be useful in general. After some thorough research on purifiers, I went with Blueair and am happy I did!”
