I've used the Fitrete filters for years. Frequent visitors have commented that I must dust the furniture everyday. I don't-the Filtrete filters keep the dust and dirt to lower level so my allergies and asthma are more manageable. There has been no reduction of heat pump efficiency
Since 3M introduced the 1900 Series Home Air filter, I have been a regular monthly user! We have COPD, own multiple cats, live in the woods and have a major freeway in near our home! The 3M 1900 Home Air Filter makes our home air clean, fresh and 100% odor-free! This is the best home air filter we have used!
I am a 24/7 allergy burdened person! I am allergic to house dust, tree pollen, grass pollens, animal dander, etc! This Filtrete Filter helps with my breathing and lessens my allergy suffering as well as the normal house dust - YEA! Thanks Filtrete, Keep up the good work!
I used to feel like I had a brick on my face when I tried to sleep at night - the congestion was THAT bad! So I decided to invest in a case of Filtrete filters. WOW! What a difference! I sleep so much better now. The massive congestion is gone!
