Review on Wein Minimate AS150MM Air Supply Minimate: The Ultimate Personal Air Purifier by Rick Pickering

I have owned this product for several years which I bought from one of the electronics stores in the mall and it has been flawless! It was recently stolen and I have ordered a replacement here at Revain. The ONLY difference from the original was that the battery was swapped for installation. This confused me and I sent the first one back as defective. When the second one arrived before the first one had even returned I took a close look when it didn't work either only to realize the problem was me! I apologize for my inability to SEE and not assume they were the same just because they looked the same. In fact I think this one is much stronger than the first one which costs more. I've always used this on flights as I fly a lot internationally and recycled air is terrible for my sinuses." It works like a gem. NO I don't use lithium batteries in flight but they work fine with a camera battery of the same size, which is approved for flights.When I returned the first unit as defective they called from the company and were understanding when I explained that after the inspection the defect was NOT theirs but mine.I would highly recommend this product to anyone recommend to anyone who needs air purification, be it on an airplane, at home or anywhere else.GOOD PRODUCT!
