LEVOIT Smart Wi-Fi Air Purifiers for Home Bedroom 83㎡(CADR 400m³/h) with HEPA Filter, Air Cleaner for Allergen and Pollen, Pets, Dust with Smart Sensor, Auto Mode, 1-12 Hour Timers, LV-H133

I have had a Levoit EVOIT LV-H133-RF for a while and it has been great. It started making a noise and I think the bearings were wearing which can happen. Levoit customer service replaced the unit with a new one within 2-days. These highly efficient air purifiers and the large capacity filter drum, readily available on Amazon, has a 3-stage true HEPA Filter. It filters air free of 99.97% of pollutants as small as 0.3 µm such as dust mites, pet dander, and pollen trapping dust and micro particles and passes air through a final carbon filter. One of these towers works in a room up to 83m² which great for a large room. The best thing about this is it uses a small internal detector to monitor air quality and will adjust itself automatically to clean the air. I use mine in the bedroom on low speed and it is silent. Even on high speed the fan is quiet, I have a second Levoit in the living room and a Levoit automatic humidifier. I recommend Levoit for excellent quality products and the best customer service there is which is why I only buy from them. Cannot fault them.

I looked at at least 10 different air purifiers and even made a spreadsheet comparing features before I chose this air purifier. I spent a little more than I was planning to spend, but it was on a discount when I bought it. It's much bigger than what I was imagining I'd end up with, but for the space I'm in, it's the right size.*I'm noise sensitive and it is really quiet. I keep it on the night setting all the time unless there's a reason not to.The light will show the air quality which is a nice feature but I normally keep it turned off.I sleep better at night - I was struggling with sleep and for some reason, this genuinely helps.I've come off my asthma medication and I seem to be fine (I don't recommend that everyone does this though, I only have mild asthma).I chose this one because it's got a HEPA and activated carbon filters. This deals with both allergens and smoke.I've only had it a couple of months, but so far, so good :)*I learnt you need to look at the Clean Air Delivery Rate (CADR) to check between the models what size room they are good for. Some manufacturers will say that an air purifier will be good for a really big room but it would only filter the air 3 times an hour. It's better if you can get an air purifier that filters the air for the room size 5 times an hour. So it's better to look at the CADR rather than just trust what the manufacturer says the room size ought to be.

Have been using for a week and it's working well,Very quiet, no problem sleeping while turned on.But it's heavy and probably not made to be moved around.

Not the cheapest purifiers on the market, although I believe it's worth it. Rooms cleared within minutes and back to fresh air in no time. Highly recommend.

This is amazing, I don’t know how I’ve gone so long without one. It clears the air perfectly, leaves no lingering smells and I don’t think I’ve ever been able to breath in so well. The air feels so pure you really do notice a difference. I’m a smoker and it gets rid of all the smell and smoke after about 10minutes. I love the light indicator at the top that shows how good the air is and changes colour when it’s having to clear the air more. Also I love the design, it’s not too big and not too small I also find it lighter than I expected and I’m able to carry it up and put it in the bedroom with me at night. Everyone that has visited has noticed a big difference and compared it to being better than outside, which I do agree. If your going to buy a Air Purifier. I would recommend this one it may be a bit more expensive, however it does what it says and worth every penny. To me now you can’t put money on fresh air. So highly recommended 10/10

Absolutely love this HEPA air filter. The large, cylindrical filter makes it super quiet. Never buying another brand air filtration unit!My only small criticism is that its easy for kids to thin/tiny stick things like papers into the fan at the top, and once a playing card got in that was really tricky to remove, but eventually we fished it out, eplained to the kids why we mustnt do such things, and haven't had a problem since.

I've found the air purifier to be pretty effective, the amount of cat fur it pulls out of the air in my house is frankly slightly horrifying.There are three power settings, on the quietest it is almost inaudible, the middle one is noticeable but not intrusive, while the top one is fairly loud (obviously it clears more air that way, so I tend to preload it in the room a while before on full power and then reduce it when I'm in there).The air quality sensor seems pretty good, it can tell when we're cooking a couple of rooms away for example, and the LED ring on the top lights up to tell you how badly you're burning the food.Having said all that, I can only give it a single star overall for the very simple reason you cannot buy replacement filters for it, meaning after 3-6 months you have a very expensive ornament.I would rank it higher if the replacements were available, but don't make my mistake.

Suffer from Allergies and the latest dog we’ve acquired did not help. Already had a more expensive air purifier for use in bedroom which I still use. However to cover the open plan kitchen dining area would have cost 2 to 3 times the cost of the Levoit If I’d bought my original make. Needed a quiet model which would work while watching TV or listening to music. Took a chance that this cheaper option would work and glad I did as it runs very quietly on the auto setting. Wondered if it was really working but it kicks in if my cooking skills not up to scratch and although noisier doesn’t take long to revert back to the quieter mode. Also shows a colour change when it comes across anything Smokey or Smelly. Tempted to maybe consider and get another one for the bedroom as much quieter than my other one. Impressed by this companies products as recently bought their humidifier which also does a great job.
