WEN Woodworking Air Filters, 5-Micron Outer Filter for 400 CFM Air Filtration Systems, Two Pack (90243-027-2)

Hi, they fit perfectly in my WEN filtration system. The filter picked up a lot of dust, for I used it while sanding down a hardwood floor. Less dust, the better for all, from air breathed in (still wore a mask) to the dust upon the walls and floor. Will use the WEN whenever I am sanding or cutting much wood. Thank you

Works great.

Works great and can last awhile

good quality for the price, keeps the air clean

These are good filters but I don't notice any difference between these and the cheaper non-charcoal filters.The specs are actually the same at 5 microns limit. The only advantage to the charcoal filters that I can detect is that you can more easily see when there's a buildup of dust on the black material when it's time to change the filter. These cost about $15 each. The non-charcoal filters cost about $7 each. I'll be buying the cheaper non-charcoal filters in the future.

no door knock, no doorbell, package left on grass ,not on front porch. product great!

Sadly, Rikon does not support its filtration units so I decided to take a chance and get the WEN two pack for this filter hoping that it would fit the slot on my Rikon unit. The dimensions were not exactly the same (a few milimeters difference but I was very happy to see that the filter installed perfectly with no gaps (as a filtration filter SHOULD fit). The price was great and comes in a two pack so I'm ready for changing out the filter in the future.

They work on the Wen and are are very simple to change. It's nice to use a carbon filter and it really keeps the dust down
