Welcome to AIRFLOW1, where we are striving to produce the best, most cost effective line of Clogged Filter Monitors for residential and commercial HVAC systems.
HVAC filters are for the most part, out of sight and out of mind! Using a Clogged Filter Monitor helps you stop throwing away good filters while tossing out bad ones. This saves you money while helping to protect the environment.
We will be launching a new online store the first part of 2018!
Thanks to everyone for your support!
The CFM-GM and the CFM-WM are our first products to be released. The CFM measure a filters differential pressure and when it is time to change the filter, the red LED begins to blink.
