Customer Ratings & Reviews

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.

Filters last a while and are easy to change. Bought it for allergies at night and haven’t had issues since

Ive had mine for about a year now, only needed to replace the filter once slowly approaching my second time. i love this thing! quite is super quite and full blast get air moving! it filters great and i can definitely tell theres been a difference in my air quality. the VOC reading is common now but i find it to be sensitive at times. overall i cant smell my dog when i walk in and theres definitely less dust around

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.

Excellent filtration, low noise and amazing performance

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

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.

App is simple to use, it's easy to set up. Honestly, it has eliminated odors. We have 3 dogs and it doesn't smell bad at all lol. The filter last quite a while too.

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

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.

My wife and i love it. We can really feel the difference in air in the living room. Really does make it feel fresh. We use Scentsy in the house and this purifier doesn’t take the scent away as fast as our okd purifier. Sound quality is great. We can barely tell its in the room.

Great item for quality air that you could breathe after using this item easy to set up in your phone and ready to use in just minutes clean the air and you can feel the difference before and after I enjoy with my family this item I will recommend

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.

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

This is my 3er Levoit air purifier. All of them are still working, other two have 5 years already and this one 5 month use. We have two cats and it has been working very well catching air and controlling odors from my cats. I have all 3 inside bedrooms, I have not try them in the kitchen , planning on buying another one soon for that area. Filters are ok on price and It last me about 7 month to be completely dark dirty. About the month number 4 I remove them and dry clean it out side to remove the amount of dust and particles attached to it and them I put it back until is all blank. They are very easy to handle and very nice looking. I have them in white but they are very easy to clean if they get dirty on the touch. I highly recommend this item, they have worked very well for me.

I love this air purifier! It is quiet and it has a variety of settings. I definitely can tell the difference in my air quality. I run it non stop when the neighbors are burning their leaves and I can tell a difference in my reactions to the smell and smoke when the unit is on. I highly recommend!

Love this purifier! Kind of pricey but well worth it! Love that I can control it and see the air quality and my towns air quality on the app too! I suffer from allergies and also didn’t know till this year I’m allergic to hickory and we just moved into a house with a hickory tree. This thing has saved me from the most excruciating allergies this season!
