MFRESH Mini White AT50 Adjustable Air Purifier Air Cleaner Air Ionizer Ozone Ionizer With 30 Minutes Auto Off Feature

This could have been a great product, as ozone is a very effective oxidizer of room odors. The AT50 is effective in that regard, and the 30-minute auto shutoff feature is nice to have. However, the product was advertised as 'adjustable' which it is not. The output of ozone is constant while the unit is on. This is a problem because when used in small to medium sized rooms, the smell of ozone is always present. For some, this might not be a problem, but when I walk into a room I don't want to smell either ozone or room smells. I would like to be able to adjust the output of the machine so the ozone smell is slightly below what is detectable by nose. It's false advertising on the company's part to claim that the AT50 can be adjusted. There is no control for that purpose.

In the past, I was dubious on any non-natural air refreshing method. And I am very sensitive to perfume or fragrance. Therefore, I never have any scented air refresher or scented candle at home. However, having a no nature air flow and no window master bathroom in a high rise condo, I have trouble to handle the smell of the bathroom since I moved in to my condo. But, until I was given a gift of this compact air purifier, I realized that I should've considered it long time ago. The bathroom smells so refreshed even after the auto program given my master bathroom is doubled than the regular condo bathroom. The 30-minutes auto shutoff program is convenient so that it shuts off before I go to sleep. The operation is relative quiet and stand-able. The manual needs a bit sharpened to be clear why you can't turn on during sleep. Not everyone is a scientist understanding the mechanism and hazardous. But overall, it's a good product. It will be much better if it doesn't take up much outlet space, aka, much better if its much more compact.

We run this in a room that has limited air circulation and it really works after 30 min. It takes out the stale air.

works great

work well

DO NOT BUY. ORDERED 6. 4 HAVE NOT MADE IT A YEAR. SELLER WILL NOT RETURN EMAIL TO COVER WARRANTEE.

Should buy it earlier, make you want to stay in the restroom longer.

Worthless, in my opinion.
