LEVOIT Core 400S Air Purifier Smoke Remover Replacement Filter, 4-in-1 True HEPA, High-Efficiency Activated Carbon, Core400S-RF-SR (LRF-C401-BUS), 1 Pack, Blue

It filters

Wrong size. My mistake

I just got this filter and the air purifier today, set everything up and the app is saying the filter life is already at 89%. Do I get a 11% refund on my purchase then?

Love that the app notified me when it was getting close to needing a replacement filter. As you can see from the picture the old filter is really dirty meaning its doing its job. I did purchase the air purifier during a wildfire in August so I suspect the replacement filter will last longer.

The purifier was easy to set up and I love I can change it with my phone. It works great and is not noisy! On high it is a little noisy but I very rarely have to use high speed. I cooked salmon and it smelled up my house, but I turned my purifier on high and in less than 30 minutes the smell was completely gone!! I have since bought a second purifier for my bedroom. I love the sleep mode you can’t even tell it is running. I highly recommend this purifier, in fact both my sisters bought one because of my recommendation. My allergies are so much better.

my husband is a cigar smoker and we have 4 cats not in house but in sunroom and we placed the air purifier in there , cleans the air in 10 mins no smell just clean ..filter lasts about 5 months

After researching nearly every type and brand of Air Purifiers for many days, my husband and I decided to order the LEVOIT CORE 400 S AIR PURIFIER for our living room because it had so many positive reviews. Everything was working fine and we were pleased with the results until 6 months later when I ordered the very expensive LEVOIT replacement filter. I put the new filter in a few weeks after it arrived and turned the air purifier onto the AUTO setting which is what we always kept it on. The following day I happened to notice that there wasnt very much air flow coming out of the top of the unit like usual so I turned it onto the highest setting and the RED LIGHT came on that said CHANGE FILTER I couldnt understand why it was telling me that as I had just put the new filter in the day before. I turned it off and back onto auto and it started running at the high (around 244) with the red circle light as if the air quality was bad but there still wasnt much air flow out of the top like there usually was when it would run that high So I shut the unit off and doubled checked to make sure I had removed the plastic covering on the filter even though I had remembered removing the plastic, but I double checked anyway and seen there was no plastic. Put the filter back in and turned it on and the same thing.. It started running on high between 200 and 245ish with the red light and barely any air flow coming from the top. I shut it off. My husband said to just keep it off and he would look at it when he got home. 2 days later, my husband vacuumed every speck of dust off the outside and inside of the unit, turned it on and off a few times and nothing helped.. It was still showing bad air quality and barely any air flow was coming from the top. We figured it must be the new filter doing this because it was working fine until we put the new filter in. So the following day, I got onto the Amazon chat to discuss the issue and they said someone would email me within 48 hours to which they did. They told me beings I was 2 days over the 30 day guarantee , they could not help me. So, after spending $189.99 plus tax on this LEVOIT air purifier 6 months ago and then another $49.99 plus tax on a new filter that we used for 2 days, we have nothing! It now sits in our office closet . We dont even know if the problem is the filter or the unit but I am not about to spend another $50 on a filter to find out that the unit might be bad. UPDATE>>>> I emailed LEVOIT a few days after writing this review because it was really bothering me that $240 was down the drain! Allison, from their customer service emailed me back within a few hours and asked me to take the filter out and turn the unit on. I did and suddenly there was a ton of air flow coming from the unit again which told me (and them) there was no issue with the actual unit and the problem was the filter itself. They immediately sent me a new filter out which we received yesterday and everything is working great again. WHEW! I did ask them if they had ever had this issue before and Allison said they rarely have ever had this issue before and she has no clue what may have caused this. The mystery lives on but the wonderful thing is, LEVOIT stood behind their product and for that, we will remain a LEVOIT customer! THANKS LEVOIT! WE Love our LEVOIT Core 400 S once again!

Ive been using the regular filter for quite some time now. I ordered the pet one this time. Im sure it is just as wonderful as the regular. If youre buying this, I imagine you have the levoit air purifier that matches and already know how easy installation is, and I doubt that I could put anything in here that you dont already know.

I’m using 1 in my bedroom and one in my living room. Big difference in both rooms Love it

I recently moved in with my girlfriends dog. The living room felt stuffy and I believed it was just how the house was. After putting the new filter in and putting it in that room it felt like a breath of fresh air. It’s amazing how well it works. Expensive but worth it.
