I have dogs!!
I have 2 dog a short hair and a long hair dog, so I ordered two of these for different areas of the house. They have been a good investment. I waited several weeks before reviewing because I wanted to see if they really attracted pet hair and dander. Guess what? They do! Normally I change A/C filter every 30 days. At $16.95 per air filter per month that is $203.40 per year, (without tax and shipping).  Between these two air cleaners I now change my A/C filter once a month.
