Customer Ratings & Reviews

Easy to operate and connect to the phone. Great looking design. No good odors after cooking. Highly recommended

Filter life is outstanding. Silent operation but plasma setting is beginning to become audible.

Compact and effecient HEPA filter system, reduction of dust, freshens air, removes odors. Bought 2 - upstairs master bedroom and downstairs for great room and kitchen area. Easy to move and timer to set run time 1 to 12 hrs a day.

I couldn’t be happier with this purchase. It’s extremely pleasant-sounding at full speed and has replaced my sound machine. It is also near silent at lower speeds. I control it from my cell phone. It’s also beautiful solid. I love it so much that i carry it back and forth from the bedroom at night and to the living room in the daytime. It’s the most expensive option i was considering and I’m so happy i splurged in this one.

Purchased this air filter for a 800 sq ft apartment to help contain kitchen scents after cooking. Immediately after the easy setup, i tuned on the oven and it sensed the residual smoke as the oven was heating up. It cleared out the oven smell quickly and then .Shifted back to clean air mode. First impressions i was blown away by how quickly it can remove the particles. Highly recommend.

Works well, we have 3 dogs and 3 cats and it has noticeably decreased the amount of fur in the air.

This is a great product. Very quiet and efficient. Works with Alexa. I have this set to come on and off during the day and set to auto which will change air speeds based on the air quality. This does its job with out me needing to do anything. Cycles air in a large room within a half an hour.

Excellent air purifier. Does a great job getting rid of pet and food smells. IOS app also works great on iPhone.

House air is much cleaner and noticed I don't have to dust as often. Great help for controling allergies!

I purchased this in November 2022 during the Black Friday sales event. I absolutely love not only how the machine cleans the air but how rapidly and efficiently it does. It is very easy to use especially remotely via the VeSync app — I am able to set schedules, timers, turn on/off the device, check statistics pertaining to PPM and run times, and the option to set plasma pro mode. I find the unit's filter very easy to remove and clean. The exterior of the unit is also very easy to clean with a microfiber cloth. The 400S PlasmaPro is a very powerful purifier for the price range. It performs amazingly with pets — I have two cats. It sucks in the fur and dander and I don't suffer nearly as bad from allergies as before. I am very humored to say that both of my cats LOVE the 400S PlasmaPro and I always find them sleeping near it and the 200S (another Levoit model). They must love it and the clean air it gives them too as I have noticed they sneeze way less. Overall, I most definitely love the 400S PlasmaPro. It has my utmost recommendation for any allergy/asthma sufferer, pet owner, health-conscious individual, and anyone else looking for overall cleaner air. I love Levoit products and especially the 400S PlasmaPro. I would buy 14 more if I could because that is how much trust and confidence I have in the 400S PlasmaPro.

Seems to work well. Gives us better night sleep. One thing I wished I had noticed early on was that the button that looks like the sun turned off the very bright display. That was making me unhappy for about a week until I got to messing around with features. I like the noise but some people might think it's too loud.

This air purifier is amazing my room is so fresh and it helps with my allergies.

One of the quietest air cleaners I have purchased. Mobile app is great to review settings and make adjustments. The fans ramp up sometimes when we are cooking but otherwise are barely audible.

Works great, if it detects low air quality like when the house was filled with smoke from me cooking to many burgers in the air fryer you get a notification on the app to turn it on, it also provides a nice background noise to help you fall asleep, it’s a win win

Had this for well over a year and it’s worked as it should. I do have he filter subscription through the manufacturer and I never have to worry about it.

This air purifier works wonders. Bought it for my daughter's apartment. She has cats, and I went for my first visit, let's say I didn't walk into a room of roses. Bought this and within 24 hours the apartment smelled so much better. Most of the smell was gone and the air just felt better. Very quiet when on automatic mode. Highly recommend!!

Looks great and more importantly, works very well and is silent on the lower fan speeds. I also have four Dyson HP01s and bought this to supplement them ahead of allergy season. The 400S is noticeably quieter than my Dysons (but I also use the Dysons as space heaters). Great price and features. App is very easy to use and no issues with connection or setup. Only wish the information regarding filter replacement was clearer as I assume the normal 400S filter should work (this model appears to just be a Core 400S with a "PlasmaPro" function) but I do wish the Best buy or Levoit product pages were clearer on this. Best Buy does sell replacement filters but I would prefer having multiple sources given the supply chain issues we are currently experiencing globally. I guess I will find out in a few months when it is time to change the filter.

I bought this air purifier hoping it would help clean the air and keep the dust down inside our home - and it works perfectly. The difference is unbelievable. An added bonus is that the purifier is soooo quiet that I often check to make sure it's on. I am extremely happy with my PlasmaPro 400s.

Works great. So quiet. Helps keep our air quality great.

Left my apartment with fresh air in minutes after putting it together and messing with the settings which are very easy to use. Is a must have for anyone that want to reduce dust and allergens.
