WEN Woodworking Air Filters, 1-Micron Inner Filter for 400 CFM Air Filtration Systems, Two Pack (90243-026-2)

I use the "WEN 3410" workshop filter, and these are the 'inner filter' for that unit. They fit pretty well, and definitely can cut down on the dust in my (woodworking) woodshop, so that's been a big help. I do a lot of fix-ups on finer/vintage/antique furniture, often with 320+ grain orbital sanding disks, so I really make a LOT of fine wood/varnish/paint dust. You should surely make sure to also use a respirator or at LEAST the "Covid-era KN-95" masks with a decent seal around their edge so you don't breathe the lingering dust before it gets removed. The antique wood can be impregnated with old, lead-bearing paint and if you BREATHE that, you get lead into you just as badly...or even worse?...than if you ate it.That workshop-filter unit and this filter (and also the important outer, 5-micron filter too!) helps to massively reduce the dust in my air. Since my workshop is a room attached to my proper house, and since I'm lazy like any real human being and I don't keep the door into the house fully closed all the time, I really need to limit the dust that gets into the house, leaded or just-wood-dust or whatever, and these filters are an enormous help in this task. In case anyone else is silly like me, I also use "EnviroCare" vacuum bags for my sander-vacuums...they aren't professional vacuums meant for it, but those bags help cut the fine dust a lot, and the room air filter REALLY cuts down on whatever is left in the air. If I am too lazy to close the door fully, then I need to use these filters to keep the dust down in my house. :DThe 1 and 5-micron filters can jam up quickly if I sand without my vacuum on/attached properly/whatever, so keep spares on hand for when you need them.

Works well with compatible Wen system

Haven't used them yet will update later

Fit and work perfectly. You can blow them off and reuse them easily.

Great product for the price. I've had this air filter for about 8 months now and I'm really happy with how it performs. I use it for lint and tack spray in a silkscreen shop and other debris in the air ,not for wood working, and it's awesome. It's actually too small for the space and I need 2 for the square footage of the shop but it still performs well. First time I changed the filter since February and the inside of the unit was 100% clean, so the filters do their job well.

The filters I recieved are different from those in the listing photos, but I think they're probably better. They're bent aluminum instead of riveted pieces, but I don't think that matters. They came with squishy foam around the edges, and the fit into my WEN filtration units was very snug without any chance of air circumventing the filter. Air flow increased substantially after I swapped these out with the old ones.

I needed this filter replacement but Rikon doesn't support it. I gambled that it would fit into my unit and it actually fits perfectly and looks exactly the same. The price was great for a 2-pack. HIGHLY RECOMMEND (which is surprising since I never recommend WEN products - typically low priced chinese junk).
