My family and I all have allergies and so efficiently filtered air is a necessity. The filters 3M produce are like everything else they produce absolutely the best quality and I have never been disappointed nor do I shop any other brand.
I had these in for the past year and they seemed to work quite well, although I don't know how much more effective they are than say the 1900 model. I do know that I currently have a generic filter in my furnace which has a 7 rating and the dust in my home does seem to be more noticeable.
obviously the higher the rating the better the filtering/cleaning of your air will be. I go with the black color label or better. u will definitely notice your air smelling better - or not smelling like it used to! worth the price and will keep you healthier
I use these filters in both of my two A/C and furnace units. They greatly reduce lint and dust, especially in bedrooms and eliminate all cooking odors, allergens, etc. Been using them for years. I replaced my electric high voltage filters which were always a problem with these Filtrete filters.
I always buy and replace my air filters every other month because I am concered with pet dander and smoke smells. This filter performs above my expectations.
