My family is very prone to allergic reactions from inhalants in our home. We have dogs and, of course dust issues and this is one of the best at drawing in and trapping those allergens.
Expensive but lasts a long time...not the twelve months it says in the ad. We change every three months but we live in the South for the air conditioner runs a bunch.
I purchase the normally 3M 1000 'red color' wrapped filter that I used quarterly. I think it works wonderfully. It is the best product for me for my house, quality wise and price wise.
I am asthmatic so CLEAN AIR is not a low end necessity for me - it is a HIGH END necessity. I am very happy with my indoor air quality and knowing that I am able to stay healthier with cleaner air is double payback. I share with all people I come in contact with that what type of house air filter you use to clean your air DOES matter.
