The amount of particles that this screen collects in 3 months is amazing! I have 2 cats and I know this filter is a big help in keeping my home clean. I hate to think of all that is collected hanging around in the air that I breath.
I am extremely satisfied with the Filtrete filters that I use in the heating/air conditioning system. They are pretty dirty when I change them every 3 months, so I know they are doing their job.
My family has lots of allergies and our home had water damage in addition to being located across from an orange grove. This filter keeps the air in my home clean, clear, and comfortable for everyone. We have been using this filter for 10 years. I see no change in the forseeable future.
These are the only filters we use. They are absolutly the very best on the market. Don' t. Waste your time or money looking for generics. Buy 3M Flitrete
