Grab This Top-Rated Air Purifier For $75 Off During Amazon Prime Day - Forbes

The Prime Early Access Sale is halfway through, so if you've had your eye on air purifiers, your time to save may be running out. With winter just around the corner—and with it, lots of imposed indoor time—now is a great time to invest in something that can help clean the air that you breathe. One top-notch pick that's up for the task? The Coway Airmega, a sleek little unit that's amassed almost 16,000 5-star reviews on Amazon. Better yet, this October Prime Day, the white model (it also comes in black) is currently 33% off for a savings of $75.

The Coway Airmega features HEPA filtration, the gold standard in air purifier technology. Additionally, it has two other filters—a pre-filter and deodorization filter—that work together to eliminate 99.99% of particles down to 0.01 microns and 99% of volatile organic compounds from the air. (To put this into perspective, a HEPA filter on its own eliminates 99.97% of air pollutants down to 0.3 microns.) Simply put, this powerful purifier can eliminate allergens, irritants, chemicals and stuffy odors from your home so you can breathe in cleaner, healthier and fresher-smelling air.

What we love most about this unit, though, is how petite it is. While dutifully compiling our list of the best air purifiers currently on the market, we determined the Coway Airmega to be the absolute best compact model you can buy. While it certainly isn't the tiniest unit out there, it's mighty for its small size—17 x 18 x 10 inches. And though the Coway can't purify your entire home's breathing air, it covers up to 361 square feet of space. For reference, the average bedroom is between 130 and 200 square feet; master bedrooms, on the other hand, typically measure between 200 and 350 square feet.

While you could run this unit in a living room, we mention bedrooms for a reason. With a decibel rating of 24.4 dB to 53.8 dB, the Coway Airmega is hush quiet, making it a great model to run while you sleep. But that's not to imply this mighty machine isn't great during the day, too. Through a colored LED display, the unit communicates your air quality in real time; if it ever senses that your air is as clean as it can get, the fan will automatically stop to save energy.

All that, for the reasonable price of $155—certainly not a bad deal for cleaner breathing air.
