Bests & Worsts Reviews from Amazon

These air-filters are fantastic! I order two at a time because it's less money if you do than ordering just one. I just replaced the first filter a month ago and it lasted for the entire three months. It was super easy to remove and then install the new filter too. I live in Az., where it is DRY and VERY DUSTY and the Medify machine with the air filter works great! I have terrible allergies (hay fever) and this machine has helped me greatly.
