Let me be the first to tell you that this gadget is amazing! ...

"For the first time in a while, the kids don't wake in the morning all coughs and sneezes. We are no longer taking any allergy medication. ... Thanks to the X8, we are finally dealing with the cause and not just our symptoms."

"This is the best air filter I've had. I'm in love with it. ... Due to cat dandruff, I have a hard time breathing. It is hard for me to sleep at night but since getting the X5, I am sleeping all night now and breathing through my nose again."
