I can't wait to try this. Tried it, loved it!

Wow, what a difference in just one day. It was so easy to set up. I like its size because it easily fits on my desk and makes life easier with a heavy smoker if you are allergic to tobacco. One of my colleagues said she also found a big difference since we didn't have to sneeze all day.

Pros
  • High marks for support and durability from testers
Cons
  • I vaguely remember

But great air purifier.

The air purifier is working properly. However, you will receive a card with your purchase to qualify for a free gift. Either a replacement filter or a $20 Revain gift card. Don't fall for this or the warranty like I did. They ask for your address so they can mail it to you. They'll then send you a Facebook message to let you know they're out of stock and need your email address to send you a code for a free Amazon gift card. They also asked for my PayPal account information. I wish I had known…

Pros
  • Acceptable
Cons
  • Not fashionable

Some 5 star ratings are ruined but good HEPA filter

1st discount Give a 5 star rating and upload a picture and you will get a free filter. I don't care about your ethics. but a good filter, cleans the air well, the filter is easy to change. It took a few hours in a closed room to clean the air (no smell) who said the charcoal filter looked a bit cheap. I chose this one because of the price. This one has two speeds and when you press the button a third time the light goes out and it runs at low speed. Big. I smoke cigars and need something bigger

Pros
  • Nice to use
Cons
  • Weight

Beware of this manufacturer

The quality of the support/service is as important to me as the quality of the product. I bought it in late 2018 and it worked fine for about 4 months and then started making a clicking noise. I disassembled it to clean but that didn't fix the problem. I contacted their support team and they initially responded with an incomprehensible very broken English response and I cannot get any further response from them. I'm throwing it away and buying a GermGuardian device. I don't know how they get so

Pros
  • Fingers crossed
Cons
  • Can I add something

Excellent purchase! on Air Purifiers

There are many things I like about this air purifier, most notably the price. This fall our area was inundated by a storm and I was concerned about what my young son would be breathing if the water receded and we could return. I bought this air purifier hoping that the air quality would improve and I have a feeling it will. He makes noises, but it's a good white noise that makes it easy for him and I to fall asleep. There are two settings and I have it on the louder setting. The size is…

Pros
  • Confident
Cons
  • Good but not great

Only 20 CFM and no charcoal

I wish I had done more research on CFM and CADR. This little device purifies the air at a painfully slow rate of 20 cubic feet per minute. This may be enough for light work in a VERY SMALL room (closet), but do the math first. (To remove pipe smoke from a well-ventilated 165 square foot room, I need at least 220 cfm!) I also noticed that the filter image shows the pre-filter, HEPA, and "charcoal" layers as three separate layers with a charcoal layer . has multiple honeycomb design. In fact…

Pros
  • Nice
Cons
  • Approximately

Stay away if you don't like disappointments and waste of time

I have updated my review. Unfortunately it broke and the seller asked for a video which I sent but didn't reply. Since it does not turn on and the seller has been missing for several weeks, I do NOT recommend it! Attention Sellers: Don't disappoint us by wasting our time with a replacement if you really plan on ignoring us. Your guarantee is worthless. If I receive a replacement that I am entitled to, I will update this part. Original review: I love it! I don't think you can do better for small

Pros
  • Many will do
Cons
  • Some difficulties

terrible customer service and a false claim about their freebie offer.

Normal product for a small home, two air speed settings, quiet mode is good, but the other speed is too loud to sleep at night. But in the worst case, the manufacturer offers a free add-on filter and a Revain gift card, as well as a 2-year guarantee, which they never want to redeem. Their customer service continued to urge customers to get them through Amazon, even though Amazon didn't offer these freebies and gift cards along with a two-year warranty. In any case, this was not a complaint by…

Pros
  • Free for educational purposes
Cons
  • Not sure
