I bought a Levoit Core 400S for Mother's Day and just set it up. My mom has been having bad allergies and sometimes has coughing fits, so I thought it could help with that. But apparently our PM2.5 is already very good (5 when I turned it on, then dropped to 1-2 after a while). We don't have any pets and clean the house once a month.

Lighter than other Levoit large room Air Purifiers BUT be careful of the bottom of this thing.
First off I have two large room Levoit Air Purifiers and I've used them for a few years. They work good when the filters are clean but not so good when they are bad. The lights don't turn off on the so I had to put gaff tape on them for night as it bugs me. The older ones are easy to change filters ...

So far so good!
I have owned this product for less than 24 hours as of this writing. More updates as I have more to say/remember to do them. Also, I will be very verbose, the sort of in-depth information I want when I am researching products over $99 for purchase, so you really know what's going on. Hopefully it he...

Used for 5 months, here's my review
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 exte...

Outstanding device, smart app wants too much phone access
The noise level is pretty quite for the amount of air it moves. It is pretty big, but not heavy enough to be difficult to move. Does a great job filtering the air. I liked it so much I bought a second one a few days later for my mom when she complained about her allergies. When you unpack it, make s...

For the money this is the best air purifier on the market
I haven't found anything YET that I dislike about the Levoit Core 400s. Some people complained about the noise, but it's as quiet at my now deceased times 2, yes it died twice in 5 years, 5 year old Honeywell; the Levoit Core 400s is about as loud on high as the Honeywell was on low, and when you pu...

Initial thoughts.
I read a ton of reviews and did a lot of research before making this purchase. I suffer from horrific allergies and for some reason they are not abating this year. I’m allergic to just about everything. My last air purifier conked out on me after many, many years. It was still running but the fan mo...
