805 HEPA Filter Mod

Added a piece of pre-filter before the HEPA. No apparent affect upon suction, protects the HEPA from hair and large particles and is much easier to clean.

I had some replacement filters from China which had a thin metal net/mesh on one side, guessing that should stop the hair and larger debris from entering the filter.
What did you use to make this?

A piece of Whirlpool air cleaner pre-filter. Carbon impregnated fiber.

I’m having thoughts of using carbon cat litterbox filter for the same purpose. They’re thin yet effective.

The "carbon" in these is activated charcoal granules, for absorbing odors.

There are odors in the litterbox. Are there odors in your carpet?

From the earliest "sticks and stones" technologies of our prehuman ancestors to the latest "high tech" technologies of today, I like studying it all!
