  • ColorTransparent
  • N95-rated filtration protects against airborne particles

Snap-On Prefilter Pack of 10

This pack contains ten transparent snap-on prefilters designed for use with Advantage N95 reusable prefilter covers. They are intended for workers in facility maintenance, traffic safety or grounds crews who need a quick way to extend the life of their primary filter media. The prefilters snap onto the existing cover without tools or straps.

Tool-Free Installation

Each prefilter attaches by pressing it onto the reusable snap-on cover until the clips engage; no screws, adhesives or separate retainers are required. The transparent material lets the user confirm proper seating at a glance. The only common issue is debris caught between the clip and the cover, which can prevent a secure lock and should be cleared before each use.

Ten-Piece Capacity

The package quantity of ten provides enough prefilters for multiple shift changes or for equipping a small team. Each unit is rated N95 and is meant to capture coarse particles before they reach the main filter, reducing replacement frequency. When the prefilter surface becomes loaded or breathing resistance rises noticeably, it has reached its practical limit and should be swapped out.

The prefilter snaps onto the reusable cover; a secure fit with no gaps around the edges shows it is seated properly for use.

What comes in the package and is anything else required?

The box contains ten prefilters; the reusable snap-on cover is sold separately and must be purchased if you do not already have one.

Which pack size should I select for the 815394 prefilter?

This item is only offered as a PK10 pack of ten prefilters, so that is the sole version available to order.
