The Abatement Technologies F621 replacement pre-filter filter is for the following Abatement units:

CAP600, CAP600-UV, CAP600-UVP, CAP1200, CAP1200-UVP, ORED600, PRED750, PRED1200

The FiberTrap pre-filter is designed to capture the coarsest particles circulating through your air duct system, which helps to extend the life of the 2nd stage carbon-pleated filter and the HEPA filter, saving you money!

We recommend you change this 1st stage filter monthly if you have pets, children & carpeting under normal operating conditions. This filter helps to extend the life of the Carbon Filter (great for odors) and the HEPA Filter (effective at capturing the COVID-19 virus).

This convenient package ships with Twelve (12) filters - ONE every month.

Filter Dimensions: 15 1/2" x 16" x 1"
