'Clean air ninja': This fan-favorite Coway air purifier is down to $151 — that's almost 35% off

You don’t need to suffer from allergies or asthma to benefit from an air purifier. Indoor air can be a lot dirtier than you think: Depending on where you live, it can be full of dust, pollen, pet dander and other pollutants. Not only are air purifiers fantastic for getting rid of airborne particles, but they can capture airborne viruses, which means you’re less likely to get sick. One of the market's top-sellers, the Coway Airmega True HEPA Air Purifier, is marked down significantly just in time for spring. (If you need a truly heavy-duty air purifier, there are more options on sale too.)

This top-seller has a four-stage filtration system that can capture up to 99.97% of particles, including volatile organic compounds and odors in addition to standard pollen and pollutants.

Why is it a good deal?

This powerful air purifier is marked down to just $151 from its usual price of $230, so you're saving over 30% out of the gate. This is the lowest price of the year so far, and the lowest price you'll find it anywhere on the web. For a brand as well-known as Coway, it's a no-brainer.

Why do I need this?

Not only is the Coway Airmega powerful, but it's also quiet. It features a washable pre-filter and a replaceable True HEPA filter. The LED glows different colors depending on the quality of your air, and the auto mode automatically optimizes the fan speed according to that quality level.

One of our writers swears by this model, calling it "sleek, glossy and a far cry from other bulky air filtration appliances." She went on to say, "At just 12.5 pounds, it's easy to move around my house if needed, and its slim profile fits into small spaces to save some floor space. (It would be great if it had a handle, but that's not a dealbreaker.) It's the perfect size for my home's needs, and I'll often keep it downstairs while I'm working, and upstairs for sleeping."

What reviewers say

"Just purchased our second," raved a repeat buyer. "This brand and model has the best bang for your buck. It's very quiet and efficient at removing pet dander, pollen, and other pollutants in your home, we definitely notice a difference when the air purifier is not running. The first one we bought is nearly three years old and still going strong in the bedroom. Replaced the filter after two years of constant use. The second Coway air purifier we recently purchased was for the living room, and replaced a Winix model which was not as effective as Coway. We love it."

"Improved my life!" wrote a five-star reviewer. "I have never had an air purifier before, but this thing really showed me how much better life can be ... I would wake up with a sore throat and would cough and hack in the morning ... I bought this air purifier and it has drastically changed how I sleep at night and how I feel in the morning. I would snore a lot (according to my wife) and ever since I got this air purifier I don't snore as much. I also wake up feeling better overall."

"Clean air ninja!" exclaimed a satisfied user. "The Coway is highly effective. During the spring when pollen counts are highest, the unit keeps my indoor air noticeably cleaner. I rarely need to take OTC allergy meds, and my dogs no longer have watery eyes. On the low setting, the Coway is silent. I have two units running now on opposite ends of a really large open family room/kitchen space and I can't hear them ... This is an excellent air purifier — the best of many that I have tried."

"Air pollution got really bad and I had been coughing, eyes were watering and I was forced to wear an N-95 mask at home just to breathe," said another buyer. "When the purifier finally arrived, I turned it on and the sensor light went red to indicate the high level of contamination in the air. I opened the doors of every room of my apartment to let it go to work and after a few minutes at full power, the light turned from red to purple, and about five minutes later, it went blue. I took my mask off and the air was pure and fresh. It is an absolute superhero at cleaning a large volume of air very quickly. I was thoroughly impressed."

"My only complaint is the sensor light," shared a final shopper. "I'm not too bothered by it because I don't have this unit in my bedroom, but as others have stated, there should be an option to turn it off completely, as it's very bright, and blue light in general is unfavorable when trying to sleep." (Psst: These affordable blackout LED covers were designed to dim bright lights on electronics.)

Over 20,000 Amazon shoppers — many of them repeat buyers — give this air purifier a perfect rating.
