Customer Ratings & Reviews

These Levoit 400 filters are Excellent.. they clean up fuzz from 3 cats and even dander pick up. I have aergies & asthma and they cant be beat! I wouldnt do without them!

Love the fact that these stay in stock, that’s always a worry of mine when buying something like this expecting it to last!

I love my air purifier and getting the branded air filter makes the world of a difference! The offbrand ones don’t fit and don’t operate like this one! It’s worth every penny for how long they last and how well they operate to make sure you’re comfortably living in a safe and toxin free environment at home! I would suggest investing in the larger air purifier like this one so you can get the most bang for your book because the amount of square footage that it purifies for is incredible!

Very happy with this choice. A noticable difference with my daughter's allergies and over all colds add sick over the months we have had it. When its on the highest setting you can hear it but not real loud the other 3 speeds are just about silent. Wife decided to forget about a pizza box in the oven...it toasted the filter but man did it do its job well. Got the smoky smell out and everything. 100% a good choice for purifier. The only downside to this air purifier is that the filter replacements arnt cheap however, most of the good air purifiers this is unfortunately the case and the 3rd party reusable ones just dont work quite as well.

Very effective filter, super easy to install! Exactly as described.

I replaced the filter in my Levoit Core 400S after the app showed it was due, and the difference was noticeable within a day less lingering cooking smell and the air just feels “cleaner” in the room. Installation was simple: unwrap, drop it in, reset the filter timer, and you’re done. The build feels solid and it fit perfectly (no gaps). The downside is the replacement cost adds up if you run the purifier a lot, and the filter life really depends on your home (pets, dust, candles, etc.). Overall, it does what it’s supposed to do and I’m happy with it just wish replacements were a little more affordable.

This is a truly great filter and worth the money. It is well made and lasts up to a year. Excellent value. It truly is what makes the air system work so efficiently.

With being an animal household, this purifier comes in handy. It clears the dander, loose hairs, the sudden aromas that happen between daily litter box cleanings and the dust in the air that comes with rambunctious cats.

Excellent replacement filter for the 400s. Easy to install, just read instructions

We got the purifier as a gift and replaced the filter recently. The purifier is fantastic. Super quiet, efficient, it's crazy to see the air quality change with the recent smoke or even just from cooking, and how quickly the purifier can get it back to a healthy level. Highly recommend!

I have used the Levoit air filter in my home for several years and appreciate the fact that I can adjust the speed level, It seems very effective. I also like that I can set it so there is no light emanating from the unit at night.

The filter was incredibly easy to change and clean in between to prolong the use. The purifier also works extremely well for my son who has allergies.

The Levoit - Core400S-P-RF PlasmaPro 400s Replacement Filter preforms well.

This product does exactly what it offers and purifies the air in your environment in such a clean manner you often wonder why its so breathable around it.

Works as intended and does it's job. I rely on these filters to keep me allergy free in my own home and these are the brand name made for the exact machines I own. The lifespan on each filter is about 3 months of use nearly 24/7 and the HEPA filter is the standard to be expected with any serious filter product.

Pretty good! I love that you’re able to use it more than once as long as it’s not really dirty and you’re able to see through it. I also wish it had a way to put a scent to it but it’s good.

Great refill, just like the original. Works great in our basement space.

Love this purifier. The filter works great. The purifier lights up with a red ring when it's time to change. The filter was so dirty. It's alarming seeing what we breathe in our own home.

This is aasy to install and there's barely any sound. It gets the job done!
