I use two of these for my HVAC system and have the pressure drop across them test 2 times per year. I find that they last for 8 to 9 months before they need to be replaced. I started using these MERV 13 filters about 4 years ago. They do an amazing job of clearing the air and are especially effective during California's annual fire season at removing smoke from the air. I find the 3 inch filters last nearly three times longer than the 1 inch filters I used previously.

Fit great and cost less than what my HVAC tech charges
