CASCADE HEPA-Rx Filter**

Designed for trapping larger air contaminants and particulates of 0.3 microns in a complex web of fibers.

** This product is not necessary if you have an electronic cell - ask about how you can easily convert your system to be HEPA based - this will allow you to simply replace the HEPA-Rx once a year as opposed to cleaning the electronic cell every 4 to 6 weeks.
