• Fresh, clean air. You need it, but the environment doesn’t always provide it.

• If you’ve suffered long enough with sinus problems, allergies, or headaches due to pollutants in the air, it’s time for an air purifier. Our top pick is the Coway Mighty Air Purifier.

You can go up to three weeks without eating. You’ll survive three to four days, on average, without fluids. But it only takes six minutes without air to damage your delicate brain, and survival beyond that is unlikely. The air you breathe is the most pressing life necessity, so why not take as many breaths as possible of pure, clean air?

To accomplish that, you’ll likely need an air purifier. Far too many of us live in areas with polluted outdoor air, and according to the Environmental Protection Agency, the air inside our homes can be even dirtier.

Common pollutants inside your home can include molds and fungi spores, bacteria and viruses, pollen, cigarette smoke, volatile organic compounds (VOCs emitted from carpeting, paint, and other construction materials), dust and pet dander, and fumes from air fresheners and other cleaning supplies.

Air purifiers remove some or most of those pollutants from your indoor air. They work by drawing room air in and through a filter or combination of filters, then blowing out fresh, clean air.

A good air purifier removes allergens, dust, gases, and other pollutants from the room air, leaving behind clean air for your lung’s benefit. There are a lot of air purifiers on the market, though, and that’s why we did the hard work for you. We’ve done our research, and gathered up the eight air purifiers we think do the best job of cleaning your air.

Here are the best air purifiers you can buy:

The best air purifier overall

Conway

Why you'll love it: Highly effective against indoor air pollution and reasonably attractive to boot, the Coway Mighty Air Purifier knows when your air is in serious need of cleaning.

The Coway Mighty Air Purifier doesn’t fool around. It has four levels of filtration: a pre-filter that captures the largest particles, an activated carbon filter that grabs onto smoke, gases, odors, and other air pollutants, a HEPA filter that catches up to 99.97% of tiny particles, and an ionizing function to increase the air purifier’s ability to freshen the air.

Its ionizing function is approved by the California Air Resources Board (CARB), which means it’s certified to release less than 0.050 parts per million of ozone, making it safe for use even if you have respiratory sensitivities.  It's best for rooms up to 350 square feet.

But that’s not the best part. The air purifier has particle sensor technology to check your room air’s quality. The device will automatically kick into high gear when excessive indoor pollution is detected, and once 30 minutes pass with air in the acceptable level, it will shut off the fan to conserve energy.

The Wirecutter named it the best air purifier, praising not only its superior performance but also its reasonable price both at initial purchase and over the years as filters need replacement.

Pros: Four types of filtration for superior performance, air quality sensor technology, three speed settings, filter replacement indicator, timer

Cons: None to speak of

The best air purifier if you’re concerned about germs

Germ Guardian

Why you'll love it: The GermGuardian 3-in-1 Air Purifier uses UV-C light technology to kill most viruses, bacteria, and mold spores.

If you are highly concerned about bacteria and viruses — perhaps you or a family member have a compromised immune system or respiratory illness — the GermGuardian 3-in-1 Air Purifier might set your mind a bit more at ease. This device has an activated charcoal filter to catch and remove smoke, smells, and gases from your room air. It also uses a HEPA filter to filter out up to 99.97% of small particles.

Best of all, this purifier has an ultraviolet light function that combines with titanium dioxide to kill most bacteria and viruses, including those that cause colds, flu, and staph infections.

There’s a filter change indicator light, and conveniently enough, the filter for this device combines the HEPA and carbon portions in one filter, so you only have one piece to change.

It works best for rooms up to 155 square feet.

Pros: UV-C light function for killing germs, only one filter to change, three speeds, relatively quiet performance

Cons: Some owners complain that the device is noisy, the combo filters are rather expensive

Buy the GermGuardian 3-in-1 Air Purifier on Amazon for $76.99 (originally $149.99)

The best air purifier for allergies

Dyson

Why you'll love it: With the smarts to analyze your air before it gets to work, the Dyson Pure Cool will make your allergies disappear. 

If allergy season has you living your worst life, then fear not: Dyson's Pure Cool Air Purifier is here to save the day. It’s capable of actually calculating the amount of pollutants in your home, and then automatically adjusting itself to filter them out. Because let’s be honest — you literally can’t do that yourself.

While other air purifiers try to capture most allergens and pollutants, the Dyson Pure Cool ups the ante by removing up to 99.97% of the stuff that’s making you sneeze and your eyes water. As a result, you’ll likely notice considerably fewer symptoms after letting this purifier do its job for awhile — I certainly did, and so did my colleague Mara Leighton.

Thanks to the 350-degree oscillation of the Pure Cool, purified air won’t be relegated to a single corner of your room. Rather, you’ll get practically comprehensive filtration, which likely contributes to its 99.97% cleansing rate. For easier control, the purifier connects to both the Dyson Link app as well as Amazon Alexa, so you can tell the machine what to do either with the tap of an app or with the sound of your voice.

When it’s time for you to go to sleep, the night-time mode ensures that the purifier is quieter, and its LCD screen is dimmed.

Not only is the Pure Cool particularly effective, but it’s also extremely well-designed. This is certainly one air purifier that you won’t be inclined to hide from your guests. — Lulu Chang

Pros: Automatically adjusts to the level of pollutants in your home, great design, 10 fan speeds for variable volume

Cons: At $450, it’s quite expensive

Buy the Dyson Pure Cool Air Purifier on Amazon for $415.15 to $450
