Multi-Tech Ion Air Purifier Review

Average Reviews:

(More customer reviews)I purchased this about half a year ago, and while it does seem to work somewhat (I can tell from dust in the filter.) The noise level increases greatly with age. It was never anything close to whisper quiet, but now it is about half the sound decibels of a running lawnmower. While I could tolerate it enough to turn it on when I was out of my room, it is now loud enough that people living in the dorm next to me can here it throughout the day. In addition to this, the effectiveness of it is dying as it gets louder. I am generally pleased with the things I buy from Amazon based on the reviews, and so despite at least six years of membership (in one way or another) this is the first review I have written. Before this I never had reason enough to warn other consumers.

Surround Air Multi Tech XJ-3000E Air Purifier Review

Average Reviews:

(More customer reviews)I have two different models of this air filter. We bought one and used it. Then, we bought another unit. They run 24x7 in my house because some family members have allergies and we have multiple pets. I've had no problems at all. The noise level is quite tolerable to us, even with one sitting right behind the sofa. One thing I have to remember to do is turn them on again after a power failure. However, that's a safety feature and I don't want most electrical appliances coming on automatically after a power outage. The big advantage to this brand is that the air filters last longer and are easy to change. In addition, the controls allow the user to select the combination of features he wants to use.
