Will You Save Money using Generic Air Filters vs. a HEPA filter?

Summary:

Companies making air filters must adhere to rigid manufacturing standards in order to use the HEPA name. HEPA is the standard. Be suspect of any filter offered at a cheaper price.

More Detail:

You may see claims like:

"HEPA-type"

"HEPA-like"

"99% HEPA"

Watch out for inferior products.

The Department of Energy has rigid requirements manufacturers must pass to meet HEPA requirements. The HEPA specification requires removal of at least 99.97% of 0.3 micrometers airborne pollutants.

Buying Considerations:

I would recommend sticking with the original manufacturer's replacement HEPA filter unless you are certain that the replacement filter is either a HEPA or up to the standards that the HEPA label represents.
