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

Did what was needed

I have had several of these which are specific for a common air filtration system. It came quickly and was easy to install/replace prior filter.

Fit was good, filter does its job. Not much to say when something does its job with out fussing about making it fit. Using it a WEN 3410 air purifier while woodworking/sanding.

These filters look like my original filter but the media looks just a little thinner. It is advertised at 5 microns, same as the original, but does look a little thinner. The media on my original is longer than the metal cage and folded at the bottom, while the new filters the media does not extend past the metal cage. You can see in the pictures I included. I do not know if this is significant, just an observed difference. Otherwise, they are an identical replacement.

These worked perfectly in my Wen air filter

Fits good works good

Works as described

I ordered these filters for my Wenn 3410 Air Filter which I use in my wood shop. The filter fits perfectly and appears to work fine. The filter material seems a bit thinner than the original filter that came with the unit however the original filter is very worn so its difficult to really tell. The filter has no markings such as the air flow direction arrow so make sure to put the side with the metal grid on the inside. I usually clean these with my shop vac or tap them on the ground to release saw dust to extend their life. I will update my review after using a while if there are any issues with durability after hours of use. If no update then it must be good.
