Assessing Your Airflow: Is Your Filter Effectively Filtering?

Airflow in an HVAC system, whether in residential or commercial settings, always seeks the path of least resistance - the air, in essence, is 'lazy'. It will find the easiest route, and if there are even slight gaps between your filter and its storage rack, the air will inevitably flow there. This results in unfiltered air circulating back into your home or business, and as it travels through your HVAC system, it can cause wear and tear that may lead to expensive repairs. Ensuring a perfect fit with your filters is crucial for optimal air quality and HVAC longevity.

Contact support if you need a larger size or assistance.

Be sure you have measured your existing filter before placing an order, some manufacturers undercut filters so don't assume what is printed on a label is correct. Manufacturing tolerances of plus 0, minus 1/8" will be observed on overall width and length of filter. When filters arrive the smallest dimension will be listed first on the label.
