NOTE: We have been selling a LOT of these since the C19 pandemic started. I am very hopeful that these are helping you all stay more healthy. We have ordered more raw material and expect to have more stock by Friday, March 27, possibly sooner.

You can PRE-ORDER at this time and your order will ship when available.

Thank you.

Your air purifier gets really dusty inside from small dust, smoke, pollen, and other contaminants. Using one of our harsh environment pre-filters allows you to keep the inside cleaner, avoid extra cleaning and keeps your warranty intact because the inside is kept cleaner. These filters fit on the back of your existing filter just under the back plastic grid that holds the filters in place. These filters are paper-thin, but work just great! They capture airborne particles, keep the internal parts cleaner, reduce your monthly maintenance, help prevent a misuse warranty condition and more. Replace each month when you clean your unit.
