Wish I had signed up a long time ago, makes the filter replacement quick and easy, and without the hassle of forgetting to replace or having to run to the store - only to find out they don't carry your size in stock! Love FilterBuy! Thanks for such an amazing service!

High merv rating with a low pressure drop
on October 29, 2018

These filters were tested in a CA dept of energy study that verified the static pressure across the filters. These filters performed best at simultaneously providing great filtering and the least restriction to air flow. Roughly 20 different filters were tested from various manufacturers. I believe it was under or right at .1 inch h20 at 1000cfm. Many manual J programs use an input of .1-.15 for residential system designs. Without measuring this after installing a new filter you are potentially compromising system efficiency and performance especially with newer variable speed systems the consumer may be negating the efficiency benefits of their system when installing filters that filter better without even knowing it. Hopefully filter manufacturers will be forced to specify the pressure drops of their filters at varying cfms in the future so the HVAC professional and homeowners alike can select filters that are both good at filtering and not restrictive thus creating the issues listed above. CA is trying to push for this by 2020.

We previously bought filters at the grocery store. Little did we know we were overpaying. These filters are amazing and about 35% below what we have previously paid. Thank you!!!!
