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.

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!

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.

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.

We purchased our air purifier last year. It has been doing a great job. Since we bought our purifier at Best Buy, we were pleased we could also purchase the new filter there also,

The filter is well made but be careful who ships it because mine was a shipped in a flimsy box and was smashed when I received it. All that aside the filter is nice and good quality.

If it’s as full of matter when I do change the filter for the first time, I won’t be surprised! I am amazed at how quiet the LEVOIT Hepa Air unit is while in operation & how well the unit performs

quiet and effective. i know it works b/c when i cook and there's more smoke than normal, it turns up the filter and it works harder. good for me in Central Oregon too, w/ the smoke from forest fires. i breathe easier. i also keep it on at all times and it never distracts from my life.
