LEVOIT Air Purifier for Pets, Home, Large Rooms, and Bedrooms, HEPA Sleep Mode, AHAM VERIFIDE, Efficient Filter for Pet Dander, Odors, Captures Smoke, Dust, Mold, Pollen, Pet Lock, Core P350-P, Grey

Have the non-wifi model. Got it in October 2019 and it still (knock on wood!) works perfectly.We have 3 indoor pets, and what I think is an above average amount of household dust. I mostly blame the two cat litter boxes - despite using supposedly 99% dust-free litter.Anyway, we run it on the Low speed 24/7 in the master bedroom (approx 200 sq ft). It definitely helps with my allergies, especially when I'm sleeping. (we also have a larger Levoit in the main living area)I love the "change filter" indicator. The filters have consistently lasted 3.5 to 4 months, and the amount of brownish-gray dust that coats the filter by the time the indicator light comes on is mind-blowing! Looks exactly like the photos of dirty filters others have posted.And whenever either of us happens to have a cold or flu we run it on Medium while sleeping, and High (too noisy for us to sleep) during the day since it can also supposedly filter out viruses. (Personally I'm a little skeptical of that claim, but figure it can't hurt)**Side Note: I recently read you can vacuum the outside of the filter to remove that layer of dust/dirt to help extend the life of the filter. I did that for the first time a few days ago with my handheld vac, so we'll see how it goes. I'm down for any hacks to cut expenses, even in small ways.As for replacement filters, for the first couple of years I used genuine Levoit filters. Then I switched to an off-brand, "Flintar". I get them here on Amazon. They're all I use now. They come in a 2-pack and the price is a good deal compared to one Levoit filter. I can't tell any difference in quality or performance.Last thing - when I replace the filter I write the date on a little sticky note and stick it on the plastic bottom of the new filter. Even though I wait for the change filter light to come on, for my own curiosity I like to see exactly how long it's been since the last filter change.

I’ve been using the LEVOIT Core300-P for a few weeks now, and the difference in air quality is noticeable — especially in my bedroom where I also have pets. I wake up with less congestion and no longer see as much dust settling on surfaces.Why I love it:True HEPA filtration: Captures dust, pet hair, and even cooking smells. It’s perfect for allergy season!Quiet sleep mode: Runs almost silently at night — I forget it’s even on.Compact yet powerful: Don’t let the size fool you. It covers a large area and works fast.AHAM Verified & Energy Efficient: Peace of mind knowing it's certified and won’t spike my power bill.Sleek design: The black version blends into any room without looking like an appliance.I highly recommend this purifier for allergy sufferers, pet owners, or anyone wanting fresher indoor air. It’s worth every penny.

This air purifier is wonderful! I have noticed such a difference in air quality, particularly regarding the diminution of dust in my home. I have a small home, just 1100sf, and this unit placed centrally seems to take care of my entire home. It is well built, very easy to use and very quiet. I also purchased the Levoit replacement filters...while more expensive than the knock-offs, I do not want to risk using a filter of a lesser quality or effectiveness.

An air purifier is not a complicated device. It is a fan, and an air filter. The fan pulls air through the air filter, and catches various particles and impurities in the air. As long as you have a decent HEPA filter, and a fan that has enough velocity to circulate the room air through the filter effectively, it will work to clean the air. You can build one yourself with a box fan and some high quality furnace filters and duct tape if you have to.So what distinguishes this one from the hundreds of others out there, why is it so popular?(1) Low up front costs - this has enough power to handle a small room effectively and a true HEPA filter at a pretty low initial cost.(2) Easy to live with - the fan is very quiet except on high, and even on high it isn't obnoxiously loud. Changing the filter takes about 10 seconds and is easy to do. There is a pre-filter to catch large dust/animal hair and the like which you can vacuum to extend the life of the HEPA filter for small particles. The unit itself is not huge or ugly, so it can sit in the corner of most rooms without being objectionable.(3) Available filters - this unit's extreme popularity means that there will likely be filters available for many years.(4) It does work - I bought an air quality meter after the recent wildfire smoke episode, and it shows me that this thing does a pretty good job in small rooms. In bigger rooms it will still provide some benefit, but it is really not able to move enough air quickly enough to clean a large room.Downsides:The filters are relatively small, so they will have to be changed fairly frequently if you run the unit constantly. How frequently? I don't know, your mileage will vary depending on how many pets you have, how much wildfire smoke is in your area, etc. But I would expect to buy at least two a year if comparing this to other units that may have larger filters you need to change less often. So think about the total running costs and not just the up front cost when comparison shopping here. If you are thinking about saving money by trying to run this in a bigger room than it is designed for, don't go down that road. You do need to size your unit to the area you are trying to keep clean. A large room needs a larger unit with a bigger fan and a bigger filter. Also, all of these things are quieter if not running on high. So it is better to get a bigger unit even one that handles more than you are asking it to, and then run it slower and change the filters less often versus trying to save money up front and then driving the thing as hard as it will go to barely get any benefit.

I love it! I bought it for my bedroom. I have chronic sinus & would get a dry cough at night. The cough is gone! It has 3 speeds. I usually leave mine on #1 which sounds like white noise. I live close to the interstate & sometimes hear the traffic at night. I don't hear anything anymore! Speed 2 & 3 are a little louder but not too loud or annoying. I'll probably buy another one for my family room. I bought the black & It looks great in my bedroom.
