I bought two of these but have only had them about a week. So far, they seem to be fine. However, you need to know that the dimensions given in the listing are incorrect. They are actually cylindrical. The correct dimensions are 8.7x8.7x14.2 inches.

I don't have any pets, but I use it in my bedroom. I run it a couple hrs and the air is fresh and clean.

The filter only lasted a month before I had to replace it. I saw another post say their's lasted 2 months while it was on 24/7. Mine wasn't even on all day.

I'll admit I'm a bit of skeptic about air purifiers but when my Midwest winter allergies seemed worse than usual (sneezing, runny nose) even with antihistamines this winter, I thought I'd give this model a try given overall it had good reviews and it had the ability to turn off all the lights at night which was an essential feature for me. I have 2 cats whom I love dearly but even if they are the source of some of my allergies, not having them around is NOT an option! Set-up was easy, just unbox, remove the filter to take off plastic bag it comes in, reinsert filter you're good to go.The night mode is whisper quiet which is great for sleeping but I wonder just how much filtration it can do at such a low speed. Fan speed 1 is a nice white noise sound if you ever need that. 2 sounds like a loud fan to me 3, well, a really loud fan--I can't see me ever using this speed altho if I needed to clear heavy smells, it sounds like it might do that quickly.One problem for me which I would have with any air purifier is that I live in an old house my bedroom is the coldest in the winter ( hottest in the summer) as it's at the v end of the vent runs. So, on cold nights, it's chilly running the air purifier which essentially is running a fan that pushes already cold air around. I've almost consider running a space heater for awhile when the purifier is set at higher speeds--brrr! But, it will prob be a nice addition to my ceiling fan in the summer.I do think my allergy symptoms improved some after I started using this in my bedroom at night. It seems like just a low dose of antihistamines is all I need now to control my symptoms but I've started to get small nosebleeds so I'm wondering if running it all night is drying out the bedroom air too much (I have a whole house humidifier on the furnace) even though I run it on night mode. I may start running it during the day instead for an experiment.It does seem to help odor control altho that is not much of an issue as the cats' litter boxes are not that close to my bedroom.Seems like a quality product. Controls easy to use as mentioned, being able to turn off all the LED lights is fantastic. Does it work? I think so but I don't honestly know--I've been using it about a month the filter has collected some visible material which is a relief as they are expensive to replace. I'd prefer a washable filter.

I bought this device because I've been told I have a variety of allergies. The device works as advertised in that it is quiet and I keep it running 24/7 in our bedroom. It is easy to operate and the sleep mode is not noisy at all. However I cannot attest to its air cleaning power since I don't have an air quality meter and my symptoms have not changed.

It works. I replaced this every 6 months. If you live in a old house 1950s or 1960s with poor ventilation, get this machine ASAP. Reduced my allergies significantly. The replacement filters work as well. I noticed reduced sinusitus and symptoms.

Third brand I've tried and this one will literally refresh a room in minutes it out works 2 of my other brand..I have terrible allergies I use this in my bedroom my allergies are so much better at night now and no puffy eyes of a morming anymore..definitely gonna invest in another one for living room

I originally want to purchase the 400 model and question if there product come with 120-220V and they said yes . But when I bought the product online I purchase the lower model 300 with new added features . But when I got the product and unboxed I was surprised this model do not have the multi voltage . Only 120V I do not have other option but just to buy another step down transformer in order to use it. I do thing this is the down side . But function wise this product is very good and very quite once it's on a sleep mode function .I appreciate if all levoit product could have product both 120v 220V this would be be use on all very the world.

I have this air purifier in my large bedroom. Dust is at a minimum, no longer do I dust every day, room smell fresh. The unit is very quiet, I love it and will buy again!

I've had this for about a month now..I order 2 of them.I have 2 dogs and this seems to really help with the stinky dog smell in the house.While I do keep my house clean..there was no way to really rid the air of dander and dust until I purchased these.I really wished that I could set a timer for each day and if there's a way..I haven't figured it out yet.This product is nice and sleek and not terribly noisy.I'm very happy with this air cleaner.

. had bad sleeping quality because of stuffy nose for years. Before I got Core300, I didn't expect anything happen but have a try. The first night, I felt the difference. I woke up in the morning with one nose hole stuffed only. I feel life is getting beautiful.So I think this product does help to improve the life quality. Today, I researched all details about this product and will put it closer to bed. I believe will get even better result!if you are in the same shoes with me, I suggest have a try.

The noise level is perfectly acceptable. While it is noticeable, even on high, it is not terrible. It will not disrupt conversation or television viewing. I usually set it to low.

I wish I had bought this years ago- I have a smaller apartment approx 550 sf and just got a rescue shih tzu. I wash him once a week but we were hit my the rains in LA- I had my doors/windows open but decided to buy this. My fan I used to circulate air died so I decided to try a filter inside as the fan got pretty dusty being run in my living room 24/7Within 20 minutes my living room smelled clean. Some people have complained about the size but I easily move it between my bedroom and living room as needed every other day or daily. I've even used it in the bathroom which doesn't have a window so can smell damp even if clean. Both larger areas are about 200 sf. I have curtains to block off hallways so the living room air refresh is circulated more. I'm not worried about the $30 Filters as my mom with COPD use to have a HEPA $150 per filter so I know these sound expensive to most people but they aren't for the quality of air being pulled through in this small machine. Will try out pet filter or environmental one next purchase.

Bought this item expecting much more than what was delivered. I figured this could eliminate all the dust that collects in my room, but honestly I haven't seen much of a difference. However it does seem to collect what may collect in the general vicinity of it.

I have really bad allergies. I run my air purifier 24 hours a day. It's not too loud and does a great job. It has helped with my allergies immensely.

We got this to combat the stale air and allergens in our office. We have noticed less sneezing and better breathing almost immediately but for me it's way too loud. My coworker likes it and says it's white noise for her but I find it to be way too loud to concentrate and we can't hear each other speak. It's actually the opposite of white noise for me, the volume of it makes it very difficult for me to have running. I guess different people will feel different about it.

ordered this item at 11 pm with promise of delivery next morning between 7:00am and 11:00am. Package was on porch at 6:00am!! I am a new cancer patient and can smell/taste dust seems like. Hoping this filter will clear up room I spend my time in.

Noise level is great!

I purchased this because it had remote control capabilities, automatic settings, and performance reporting.
