AYO WX Pleated Pre-Filter (Pack of 10)

This pleated pre-filter is designed to filter coarse particles over 5um in size to prolong the life of the AYO WX Main Filter. Unlike traditional flat-piece pre-filter media often seen from other respirators, the AYO WX pre-filter is made in a pleated filter media, achieving a high dust-loading capacity in a small form factor.

This pleated pre-filter is fitted in the AYO WX Particulate Filter Unit in front of the AYO WX Main Filter in a rubber frame. Replacing the filter requires opening the Filter Unit Door only.

This unique pre-filter helps reduce running costs significantly.
