Air filters are rated by several different metrics and systems, depending on a variety of factors. Second Nature makes filters easy by breaking these ratings down and utilizing one standardized metric-MERV.
We always want to make sure you get the exact filters you need, exactly when you need them.
Dirty and clogged air filters reign havoc on your HVAC system. They will not only waste money on energy costs, but they will cause damage (sometimes irreparable damage!) to your HVAC system.
