I have been purchasing the Healthy Living filters for several years now. In a home with pets it is a lifesaver! The amount of dirt and particles that this filter traps is amazing, I actually am so pleased when it is time to change it and I can see how hard it works. I no longer suffer with allergy issues in my home. They are a great value for the money, especially when they are on sale and you can take advantage of the mail in rebate.
