I recently purchased the Levoit Everest Air, and it has completely exceeded my expectations! Living in a smaller space, I needed an air purifier that could quickly detect and clean the air without being too noisy—this one does the job perfectly.One of the most impressive features is how intelligent and responsive it is. The first time I cooked, it immediately detected the drop in air quality and kicked into high gear to clean the air. But the best moment? When I was blow-drying my hair, and the air quality reading dropped to zero—the purifier immediately worked to clear the bad air, bringing it back to a healthy level in less than 20 minutes. It even prevented my smoke detectors from going off, which usually happens when I straighten my hair!Not only is this purifier highly effective, but it’s also whisper-quiet in normal mode, making it perfect for daily use. If you need a purifier that’s powerful, smart, and truly makes a difference, the Levoit Everest Air is 100% worth it. Highly recommend!

I've only owned this for a day, but I am so impressed already. I got it to help reduce eczema aggravators in the air since my daughter suffers with eczema. Anyways, tonight I was baking something in the oven. The air purifier always says air quality at 98%-99%. When I opened the oven the percentage slowly went down all the way to 87%. This purifier detected the reduction in air quality in SECONDS and automatically started working harder to get the air clean again. It took 15 minutes to get the quality back up to 99%. This is incredible.

When I'm exposed to pollens and other air kinds of air pollution, my respiratory system goes in revolt. I'm congested and I do not sleep well. Years ago, I upgraded my HVAC system with improved filtration which was a big help. Recently my pulmonologist suggested adding air purification. He recommended levoit (which is the brand he uses at home). Making decisions about purifier size and style (air intake path / exhaust path) takes some thinking and absolutely depends on space and intended use. [Choices are not necessarily intuitive.] I selected Everest Air for my bedroom even though it is oversized primarily because it will deliver a very decent volume ( ~ 60 CFM) silently in sleep mode, which will deliver really clean air at night. With this unit, I sleep better and wake up with less congestion. I was really impressed with the build quality, fit and finish of Everest. The range of control options seem like they could cover a wide range of use cases. Based on my experience with Everest, I'm in the process of adding 4 additional levoit purifiers (different sizes / styles based on use case) to my home. My second unit (Core 600s) is in place already. These units deliver solid value. Per Deming - Buy Quality and Save Money.

FINALLY!!! I have purchased "high end" several purifiers that promise to reduce dust yet never make much of a difference. This is REMARKABLE and the dust in my home has been reduced by at least 85%. I was skeptical to try it, but with the return policy why wait to try it? I cannot recommend this unit more highly.

1-Year Update:I've had 2 Everest Air units in my 1-bedroom apartment for a little over a year now and thought I'd come back to update. All in all, I can say this is still a 5-star product and still one of the best on the market. Everything I said originally still is true to this day. No issues whatsoever to report with either unit. The one and only negative thing I can possibly find is the cost of the replacement filters, which are $99 each, and never seem to go on sale. I have to change both filters pretty much twice a year. The first change I did I tried an off-brand that was less than 1/2 the price, but they did not fit the unit quite right and left a gap, and noticeably did not perform as well. When I just changed them a few days ago I bit the bullet and spent the $200 on the real filters and it was nice to have them fit snugly into the machines.---Original Review:Love my Levoit EverestAir! I researched air purifiers for over a month, trying to determine which had the best performance, quality filter, and lots of modern features. I watched hours of video reviews, sorted through articles, and evaluated each, including Levoit, of course, Dyson, Mila, Molekule, Coway, and Blueair, just to name the most popular that I looked at. When it came down to it, the Levoit EverestAir has the best of what I was looking for – so much so that I just ordered a second one to put in my bedroom!FILTRATION: Like another reviewer mentioned, starting at the filter and then working your way back is best, and the filter on this thing is a beast! It is massive and has a large amount of carbon pellets that you can actually see. Many other brands use a tiny sheet of carbon that does almost nothing to capture VOCs or odors, but Levoit packed a ton of carbon pellets into this filter. Plus, the laser air quality monitoring is the best you can get. It reacts almost immediately, maybe a 5-10 second delay, to any change in the air quality. I notice that it kicks up right when I expect it to.DESIGN: It is definitely not a "small" machine, but it also isn't the largest. It is sleek and looks nice in my living room, considering it is powerful enough to clean my entire 900 sq.ft. apartment. The display gives you all of the information you need without being an obnoxiously bright touchscreen monitor. I really like that you can control the display or enable the "light detection" mode which would be great for a bedroom as it automatically lowers the fan speed and turns off the display when it gets dark.APP: The app is great, I have had a Levoit Core 200 for several years and it is still running perfectly to this day, which also uses the same app as the EverestAir. However, the main difference is the EverestAir app is PACKED with features. You can view everything you can on the machine itself, like air quality %, PM1.0, 2.5, and 10, change the fan speed or place it in auto mode, view the filter life, and turn the display on or off.PRICE: Considering some of the competitors like Dyson and Molekule can reach $800 after tax, the EverestAir is a great value! Of course the sticker shock can be a bit jarring, but overall it is 100% worth it.DOES IT HELP PURIFY: It sure does! I suffer from severe seasonal allergies in both the spring and fall, and when I was home, I did not have to take any allergy medications, eye drops, or nose sprays whatsoever and I have EverestAir to thank for that! I sleep better and my furniture stays cleaner with the particulates being filtered out of the air before they have a chance to settle. My apartment is brand new and there was a bit of construction dust still in the air, in the carpet, and on the walls, and I am confident this is keeping that at bay, too, while the carbon is absorbing any Formaldehyde offgassing from the fresh paint.THE BOTTOM LINE: If you're on the fence about ordering the EverestAir and are looking at any of the brands I mentioned, absolutely buy the EverestAir! You will not regret it.
