5-Micron Outer Air Filter Replacement Compatible with WEN 3410/ POWERTEC AF4000/ Shop Fox W1830/ Grizzly G0738 Air Filtration System. Compared to Part 90243-027-2, 4 Pack

The original filter had a small stitched hole on the left side. It did not apprear to be torn but it let more dirt into that side so I'm not sure if that was part of the original design. These filters do not have any small holes on either side. Used an air compressor to blow out the dirt from the side with hole and installed this filter. Nice snug fit with the foam edges around the aluminum frame. 5 stars I'll keep these instock from now on. Puricare 500 is the same size unit as well.16.73" L x 9.72" H

These work great in my Wen air filtration box. I vacuum them out regularly to extend their life and they hold up to the cleanings well. I highly recommend having a stock of these for your workshop. The value and quality is tough to beat.

Purchased to fit the WEN air scrubber. Good quality air filter. Economical and a perfect fit!

They are what was needed.

These are nice filters but are a very snug height fit for my Rikon 62-450 (I took a chance on purchasing). Depth and width dimensions are fine. Upside is no gap on top and bottom of filter when installed. But getting it installed requires some finesse in the vertical dimension.

Works perfectly

I got these because while there are less expensive options , the price difference wasn’t that significant and I figured I’d use the ones that came with my Wen shop air purifier. Work as you’d expect, no hassles.

Good product. Perfect Fit.
