www.filterstream.com review: Their air purifiers didn't work and you waste only money

I bought home air purifier from the company www.filterstream.com. I read the instruction and used it as it was written in it, but after 3 days I haven’t seen any results or any differences. I was upset, because it was written that it would clear the air. Total scam and waste of money. I won’t buy from them again and won’t recommend it to my friends and relatives.
