AIRTOK HEPA Air Purifier for Home Bedroom with Fragrance Sponges | 4-In-1 H13 True HEPA Air Filter for Smoke Dust Pollen Pet Dander Odors,99.97% Removal to 0.1 Microns | Ozone-Free, Night Light,Black

Three speeds..not super loud..filters wont break the bank. Does a good job.

Yikes!Be lodgical people. A filter can only remove 99% of contaminants from the air that actualy passes through the machine and will work over time…1)my 3 purifiers were brand new at delivery. Some folks need to fully read what they order if they are truly getting used ones.2)on “medium“ you can hear some low white noise but nothing too bad at all. A refrigerador is actually louder. “Low” is silent. I have no clue what people are expecting “not to hear” from a machine that moves air through a filter with a Rotary fan… ( I’m happy with the very low slight sound canceling white noise )3)Replacement Filter packs are easy to find and order right here on Amazon for about $45 in 4 packs or $24 in a 2 pack some do come with more oil pads too.4)no clue why or how oils would work in a purification machine intended to remove smells and odors from a room along with the dust But I had anticipated that idea to not work well anyway and my review didn’t deduct on what shouldn’t work regardless.I bought 3 identical units and may order another unit to cover another area.Over all I can feel the air moving in my home so it’s obviously pulling air and dust through the filter. I woke up far less stuffed up in the morning and breathing feels oddly easier.I bought them to help reduce dusting and cleanning so that’s yet to be discovered because this is just week one on constant medium, I also just spring cleaned like a neurotic madman with OCD before the filters got here.Cleanning and dust Update later.Don’t believe the negative reviews on this one. The reviewers having a bad experience ordered wrong or expect a magical machine that can’t exist. This one is seriously quiet enough on medium and low. High is loud for sure but it’s moving and filtering some serious air quantity.Read the bad reviews with a grain of salt and you will see the errors in anticipation, order making and or redundant review not really on its function of air purification.One woman gave a bad review because her maid tossed out her 12 oil pads. Serious first world problem much?

I wish it stayed on longer than 8 hours but it’s great. I can tell the difference when it’s off and on. I have a large dog that sheds so it really does work at removing the allergens and dust.

I loved this air purifier so much I bought one for each bedroom. We used cedar wood and lavender in the bedrooms and stress away in my home office . We have 3 dogs and the air is so fresh, you would never know. We have a larger one in the main living area

This is the perfect size for a bedroom. It’s nice and quiet and we could tell a difference the first night of using it. I also like they flu can add oil to it to help freshen up the room

Although I do own 3 of these, I gave this product 3 stars because I still see alot of dust in my apartment, especially when I shut it off. Also the sent feature doesn't really work very well. The essential oil that I put on the pads didn’t really last more than a day so I have to keep adding more. I think that if you're looking at this product because of that very feature, your probably better off just buying a small defuser, they seen to work better. Also as many others did commented on, this air purifier is pretty noisy when you run it on the medium and high levels which you almost have to inorder to feel like it's really working properly. Some of the things that I do like about this particular air purifier is that it's small so it can easily fit on a desk or night stand and it's size makes is convenient for traveling. I also liked that it came in black and it does make the air in your room feel cooler. Although I don't really use the nightlight feature, I do think it's pretty neat. I purchased two for my living room and one for my bedroom. Since the living room is slightly larger, I put one on each of my coush and one on my desser in the bedroom. But again, I dont really feel like this air purifier is actually cleaning the air, rather I think that it just blows cool air out from the top which pushes the dust in the room around because whenever I shut it off, the dust in the room seems twice as bad! Pluss there's more dust on my ceiling fans then there is inside of the air filter on this thing... I've also noticed that I'm stills having to wear a mask in my home otherwise I break out in a sneezing attack and wake up with a sore throat. But maybe I'm just expecting too much from this little guy. Either way, it does make the air in my rooms feel cooler which in my mind translates to fresher air even if the evidence says otherwise...

Put this on my desk at work and my co-worker burned some popcorn. Worked well in clearing that funky smell around my desk when I turned the unit on the high setting. My other co- worker had a smelly lunch and it worked well on clearing the air too. Also, the unit is pretty quiet on low and medium settings. The high setting makes noise but, not that distracting to me while I was working on my computer. So far, I am happy with my purchase.

I bought 4 of these for my house. I have very bad allergies and they have helped immensely with them. I no longer use over the counter allergy medication. I run these all the time. It hasn’t effected my electric bill and it’s very quiet. I run them on medium.
