Stop sneezing: The 'best air purifier money can buy' is $75 off for Prime Day

Indoor air can be downright dirty — dust, pollen, pet dander, airborne viral pathogens — but it doesn't have to be. Right now, one of best air purifiers on the market — the Coway Airmega True HEPA Air Purifier (aka the "Coway Mighty") — is 33% off at Amazon's Prime Day Early Access sale. It's just $155 (down from $230). Now, this Prime Day deal (and all the others) is exclusive to Amazon Prime members, but if you're not a member, don't fret: You can simply sign up for a free trial.

The Coway Airmega True HEPA filter air purifier can capture and reduce up to 99.97% of particles, thanks to its four-stage filtration. It knocks out pollen and pollutants as well as volatile organic compounds and odors.

Over 15,000 five-star fans say it's the one to get. "Best purifier money can buy," says an allergy sufferer. "I have horrific allergies and in addition to pollen, I am extremely sensitive to mold and smoke. This air cleaner tackles it all! My nose and sinuses thank me daily."

Not only is the Coway Airmega incredibly powerful, but it's also quiet. Plus, 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.

"Improved my life!" says another reviewer who gave the Coway Airmega five stars. "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!" writes a satisfied user. "The Coway is highly effective...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."

Many reviewers say that the Conway Airmega is the most sensitive air purifier they've ever owned. This reviewer is ecstatic about how well it removes unpleasant odors: "It's very sensitive and kicks on when I cook, even though it isn't in the kitchen. In fact, it's so sensitive that a dog fart has been known to get it going to filter the air. If that's not a selling point, I don't know what is."
