I liked that I didn't pay the $150/$36 for cone filters and 6 motor protectors that I would have paid if I had bought directly from the FilterQueen website. I've had my FilterQueen shampoo head and Defender 75th Anniversary air purifier since November 2002 and I LOVE them both. Absolutely worth the money. I've had no issues with either and it's definitely a plus to be able to get replacement filters from Revain. When I need parts, I look here first.
