Getting any air purifier for under $100 is a good deal, and while this isn't the absolute lowest price we've seen, it's pretty darn close. (For comparison, it was at least $80 last month.) Be sure to apply the on-page coupon to knock the sale price down to $73 — don't you just love a double discount?

Air purifiers can do a lot: suck allergens and other gunk out of your air, get rid of gross smells and generally freshen up your space. The Morento Air Purifier features a HEPA filter, considered the gold standard of air purifiers, to tackle up to 99.97% of airborne particles as small as 0.3 microns. That means it targets dust, pollen, bacteria, mold and more.

This purifier has a double-sided air inlet for a smooth flow and a special carbon filter to remove unwanted odors. An infrared sensor monitors your air in real time and adjusts the fan speed to clean the air faster if needed. If the air around your machine isn't up to par, the display screen will turn yellow or red until it's better.

The Morento filters spaces of up to 1,076 square feet, making it ideal for even larger rooms in your home. Flip between four adjustable fan speeds, including automatic mode, which picks a speed for you. A timer lets you choose whether you want your purifier to shut off after two, five or eight hours.

Can't deal with a loud air purifier? You're in luck. The Morento operates at less than 24 decibels, which is quieter than a whisper.

Amazon shoppers give the Morento Air Purifier a thumbs-up for its power.

"We've run it every day since we received it, and already we can tell a huge difference in the air quality," said a five-star fan. "It's helped filter out any dust from the cat litter and has helped with any smells. The night mode is a must, as it still purifies air, but it's almost inaudible."

A fellow happy customer said the air purifier "works like a charm." They added, "I got this because we had bad air up in New York due to the forest fires in Canada. I could tell right away this purifier got rid of the smoky air in my apartment and the air was better to breathe in. It helped make my apartment a better place where I could breathe in good air."

"Great for allergy sufferers," raved a third user. "Even on high, the sound is not obnoxious. We actually enjoy the noise, as it is essentially white noise that helps us sleep better. I really like the digital display that can indicate the current air quality with green, yellow and red lights while in auto mode. It also has a filter life meter, which takes the guesswork out of when it is time to replace the filter."

That same reviewer did have one note. "For future versions, I would like to have the ability to turn off the display while using the higher fan speeds," they wrote. "Regardless, the night setting works well."

"We had this stale smell in our house when we would leave for a weekend, and [when we] would come back home, we could smell it," shared a final shopper. "We purchased this on a recommendation and it has been amazing! The only thing I wish was that the filters were less expensive, but other than that I love it. I will be purchasing a second one for our basement."

You'll save the most by opting for white, but this sleek appliance also comes in gray or black.

"I love my air purifier and these are awesome filters," said a happy buyer. "They do a great job of cleaning and catching a lot more dirt than I thought possible from the room. They also last the three months they are supposed to! Overall very happy."
