Alen BreatheSmart Classic Large Room Air Purifier, Medical Grade Filtration H13 True HEPA for 1100 Sqft, 99.99% Airborne Particle Removal, Captures Allergens & Dust, in Stainless

I ordered two of them to Hong Kong when I moved there end of 2019. One for the office amd one for home. I tested the air quality before and after switching on the purifier with two different air quality monitors, one of which I also bought on Amazon. The air is as clean as it gets when the purifier is on. The best thing about the product is that is whisper quiet on the low setting but peoduces enough air flow to clean the room. My colleagues have small office purifiers and they make too much nouse when they are on. I couldn't work in such an environment. Had the purifiers for three month now and very happy with them. If you look for one, look no further.

I love this product , I have 3 around the house . I can actually smell how fresh the air is. I bought these as I have parrots and I cant believe how much dander and pollution it takes out the air . Fabulous product , if may seem a little expensive but worth every penny , my asthma has improved no end

I bought this for my parents during this pandemic, I feel assured that all airborne particles are being processed

I bought this to combat the smell of cigerette smoke it came with the normal filter and works well.It controls the fan speed needed when in auto mode as it has a sensor on the side.It is a noisy machine when working at full speed but ok when on low.Its light enough to move room to room and has a long power leadMy only gripe is that the filters are not readily available in the uk especially if you want the odorcell filter I am in contact with alencorp regarding this but due to christmas I'm still waiting to hear where I can get this particular filter as they wont ship to ukSo a further note on this issue with filters after speaking with alencorp through email the odorcell filters are available but only from the U.S.A. and the cost is $119 per filter plus $79 post and pack but that's per order not filter.After speaking with amazon it has been agreed to return this item although it works well there is too much work involved when the filter replacement time comes.

Excellent product clears the air you can tell the difference within a couple of hours of use

filter change indicator great.

I purchased 2 Air Purifiers and I love the product, I really see a difference in the air quality when left on 24/7. But the only negative I have is that only one of the Air Purifiers gives of a odour with some sort of vinegar smell which is very strong and bad. This doesn’t seem right but I hope the company reaches out to my to see if there may be a issue with mine. The other is perfect. I feel like the Air Purifier that give of the odour defeats the purpose of having a Air Purifier as it is making the air dirty instead of clean from odour.

Simple to use and set although after a couple of weeks it’s making a slight smell in the air. Perhaps we need to change the filter. Because there is no digital display it’s tough to tell air quality or filter quality in % terms like a Dyson and therefore slightly difficult to know why it’s coming on and off every so often.
