Can I put a HEPA filter in my AC unit?

There is a lot of confusion with HEPA filters and putting them in your ac unit. This article should help to clarify that for you. 

HEPA Filters are not designed to be put into your AC Unit. As you will notice in my previous article, “Which HEPA Filter Is Best” that I outlined how each of the HEPA filters we reviewed are individual units that have a series of filters inside of them. 

  1. Prefilter
  2. HEPA Filter
  3. (Optional) Charcoal Filter

Without the prefilter, the HEPA Filter would be overwhelmed too quickly with larger particles that the airflow would be quickly interrupted and the filter would get clogged.
