Clogged Filter Monitor Indicates Time to Replace HVAC Air Filters
HVAC filter replacement is necessary to maintain optimal efficiency; knowing when to replace is equally important
AUSTIN, Texas — Airflow1 has announced a clogged filter monitor, called the CFM-GM, that signals the ideal time to replace HVAC air filters, which the company says can help homeowners keep a cleaner indoor environment, reduce the need for maintenance on HVAC equipment, and trim energy costs. The company currently has a Kickstarter campaign to fund the final development and production of the device.
Airflow1 notes that replacing HVAC air filters is necessary to keep equipment running at optimal efficiency, but knowing exactly when to replace them is equally important. Unfortunately, there has never been an easy or precise way to address that question. Filters become more efficient the longer they’re in place, so replacing one too soon is wasteful. But there comes a point when a filter is no longer performing at all, and the HVAC unit suffers a drop in efficiency, not to mention the accumulation of dust and dirt on the components and in the indoor environment. By some estimates, inefficient HVAC units waste up to a billion dollars in electricity each month.
