accidently left filter in for over 6 months--during heavy summer season use at that! this was our 52nd day of 100+ degree temps. filter handled the abuse/misuse without any sign of failure or collapse.
I always opt for the best, as I know how important air quality is. I have a daughter and grandson who have summer allergies, and I do not want to complicate life for them. So, I buy the best filters and I am never disappointed.
I have tried several air filter for my heating/cooling system but there are no comparisons to the Filtrete "best" filter ! I have persoanlly recommended it to several neighbors and relatives and the ones that switched have told me how much cleaner their homes stay now and how much better the air is in their homes. The remark that stands out the most is how "dirty the filter is when they change it. No one has seen that dirt from the inferior filters. Way to go 3M Filtrete, keep up the good work and keep those filters coming !!!!!!! THANKS
I have a new airconditioning unit on my home. I use only the best air filters Filtrete because I want the unit to work efficiently and not get damaged. I breathe better and know that my air conditioner is going to work better with a top quality air filter.
