3.0 out of 5 stars Used for 5 months, here's my review
Reviewed in the United States on 1 November 2021
I have used this for 5 months. I’ve used it 2.5 months in my 350 square foot bedroom, and another 2.5 months for my 650 square feet living room. Yes, I know this is rated for like 400 square feet, but here’s my review anyways.

So here are the summary PROS and CONS, if you’d like to skip all the extensive details I will be going into…

- Has auto sensors
- Has quick timers on it that include 1h, 2h, 4h, and 8h
- Has 4 fan levels
- High CADR of 403, which means it is for large spaces and performs at 5x air changes per hour (ACH) at max of 403 sq ft.
- Carries easily from room to room
- Turn on/off display
- Design/aesthetics
- Price point with its features are incredibly competitive compared to products in the same exact level (as in, this would have been a lot more expensive because of its features)
- Filters quite well
- Keeps smoke and odor at bay
- We love fan setting 2 to use for sleep
- Vesync integration (Levoit’s app that controls everything by Levoit)
- Alexa integration
- Apple’s Home integration
- Along this line, pretty sure it will connect with many other smart homes, like Google
- Vesync app itself is probably in a whole other category of PROs because it’s actually really great
- Vesync app tracks both indoor AND outdoor PM2.5, so you can see a history of air quality both inside and outside your house.
- Vesync app lets you set up smart scenes from within the app, so you can program it to do anything when any condition is met
- Vesync app has been frequently updating to be better and to support more, so there’s ongoing improvements beyond what I consider to be really great already.
- No deceptive ads for this listing; it tells you exactly how many sq ft it covers based on industry standards of 5x air changes, and not based on 1x air change.

- Doesn’t filter allergens as well as some other brands do, like Coway.
- Another brand may be much better for people who suffer from pet allergens.
- The bottom comes off sometimes when moving it around.
- Vesync app does not always update air purifier immediately.
- Vesync programming scenes can be finicky and not always work as intended.
- Noise level on the highest setting is very loud (but so are pretty much ALL air purifiers set on highest).

NEITHER Pros nor Cons:
- Price of replacement filters (costs about $49.99/6-12 months)

I REALLY wanted to love this air purifier. For the price, it had absolutely everything I wanted, especially the auto sensors and app integrations. It honestly did extremely well in almost all areas, except for the fact that as allergy-sufferers, this just did not work as well as I thought it would. My wife is the one who suffers from pet dander, pollen, and dust, and gets asthma from extremely bad air. For her, the air purifier didn’t make a difference at all. I’m pretty okay and just suffer the occasional seasonal allergies, so I couldn’t really tell if it was making a difference for me or not. All I could tell was that from the filters, I could see that fur and dust was getting sucked up. When I cleaned it every month, it collected a lot of stuff. So that’s good! On that note though, no, air purifiers are not meant for fur and won't help with fur. I used to think air purifiers helped keep the fur at a minimum, but nope, doesn't help at all. I have a husky... I still gotta vacuum every day cuz the fur is still everywhere. Anyways, the purifier would also automatically kick on when we fried food in the house or stir fried anything on a skillet. On very rare occasions, the forest fire smoke would come all the way from the next state over and the purifier would sense this smoke and also kick on. I was very happy with that. I tried this Levoit’s air purifier for a total of 5 months. 2.5 months in my 350 square foot bedroom, and another 2.5 months in my 650 square foot living room. It worked pretty much the same in both areas. I couldn’t tell much of a difference at all.

However, I also tried Coway’s Airmega AP-1512HH for the same amount of time. I alternated between these two air purifiers for 2.5 months at a time in the bedroom and living room as well (total of 5 months). And Coway’s air purifier was the one that actually made a difference for my allergies. For my wife, it only helped a little, but for me, I could tell a difference in as little as 10-15 minutes when Coway’s was turned on high. Even though the Airmega was rated for 350 square feet, it still made a difference in my 650 square feet living room. The airflow on this thing is amazing as well; I could feel it's airflow on high from across the room! I have so many good things to say about Coway's Airmega, but the huge tradeoff is that it isn't Wi-fi enabled. Levoit's Wi-fi capabilities plus the app made such a big difference in convenience and scheduled cleanings, that I really wanted to hate Coway's Airmega. I can't, however, deny that Coway's helped my allergies. One day after coming home from an incredibly windy day out, we both started feeling increasingly stuffier (with headaches and migraines coming on) as the evening came to a close downstairs in the living room where the Levoit air purifier was. The sensor on the Levoit shows the air was still excellent, so we just thought we were exhausted from being outside for too long. We did not take any meds. We just headed upstairs to go to bed, where the Coway air purifier was. Pretty much in 15-20 minutes with Coway purifier on high, our stuffiness eased and we could finally breath without straining, and our headaches and migraines lifted. Like magic. Allergy meds don't even work that fast sometimes. That was probably one of the very few times that we could actually compare the two air purifiers because it made such a huge difference. All the other days, our air upstairs and downstairs were usually both very equal and neither purifiers made much difference (to the point that made me feel like air purifiers are just myths sometimes, but obviously isn't).

So, after 5 months of trying BOTH these products where both have very similar CADR, I came to the conclusion that I will be sticking the Levoit in an area that has the least traffic since it doesn’t help much for allergy-sufferers. As a purifier for smoke and odor, this is actually a pretty good one though. When I cook and this turns on, my house smells less – although it doesn’t completely eliminate the smell. In fact, neither the Coway nor the Levoit was able to completely eliminate smells (but that was not my concern at all). The best thing about the Levoit, and I feel is the biggest selling point, is that it’s Wifi-enabled for an amazing price. The app is so dang good and useful that you can set this to turn on 4 times a day at 1 hour every time (or however many times a day for however many hours you want!), or control it from across the world, or set it to turn on and clean the air right before you come home. It is so handy! Plus, it works really well with Alexa. And the auto sensors do actually work really well.

At the end of the day though, my purpose for buying this were for allergies. Coway won in the area of purifying enough to help allergy-sufferers and auto-sensing. I don’t know how, but the sensors on the Coway are much more sensitive than Levoit’s; so sensitive, that opening a door activates Coway’s, while Levoit's sensors tells me that the air quality is still excellent. Now, I wasn’t here to review Coway at all, but I couldn't give a review of Levoit's air purifier without comparing the two. Looking at other people's reviews about how Levoit's air purifier helped with their allergies and such though, made me feel like either I got a defective device from Levoit, or our allergies are actually much more severe than the regular folks with allergies. Anyways, given that Levoit gave me no relief from my somewhat allergies in comparison to the other brand that I bought and tried at the same time, I will admit that I would probably not buy Levoit’s purifiers for myself ever again. If I had a friend that just needed something to keep the air clean and somewhat help with odors, AND really wanted one that’s Wifi-enabled, I’d definitely recommend this though. The app is a game-changer, and should be given an award – it’s so good and it’s always being updated; Levoit has a ton of Wi-fi-enabled products as well and all controlled with this one app. In fact, I have a Levoit humidifier, AND I also have a different small Levoit purifier for the cat’s bathroom that works extremely well too when it comes to keeping the odor at bay (so Levoit for fighting odors seems to be working pretty well in that department). Both are Wi-fi-enabled and just a game-changer. I just wish Levoit’s purifier for my living room worked better for allergies as well, but sadly, this model just didn’t and couldn’t. Pretty disappointed.
