100Pack 100Micron Paint Strainers Paint Filter with Silicone Funnel

The funnel was just about free when purchased with the filters, but I am finding that the resin tends to cling together and will go straight into the resin bottle if the filter is held an inch or so above the bottle. The filters are stiff enough to hold their shape, but will topple off the top of the bottle if not held, and if the resin is poured into the filter over the top filter, it will run outside the bottle if not held off the top of the bottle. Not a criticism of the filter, just a matter of technique.

just got yesterday,been raining,haven't had a chance to use yet.everything looks to be of good quality.

I primarily bought this for the funnel for use with resin and IPA for my 3d printer. The filters are fine, and the funnel is fine, but I do not imagine it holding up long term. Also, the collapsible nature of the funnel makes it exceedingly difficult to clean up after using it. I found that it was just easier to toss it into my UV curing station and then go at it with a paper towel to remove the cured resin. As soon as this funnel gives up the ghost I'll be looking for something non-collapsible.

I used to get these at the local auto paint store for free with a paint purchase. Can't find them locally anymore. These work just like the ones I'm used to.

This is the collapsible silicone funnel and paper filters for filtering paint before spray painting. These have worked just fine for me. It's true that the paper filters don't have a perfect fit in the funnel, but a simple fold makes them work just fine. After use, dispose of the paper filter, clean the funnel right away with solvent, and you're ready for the next time. No fuss, no problem.

I use these in my art studio to remove particles from paint that I mix up myself. I was tired of having to pick out pigment that hadn't fully dissolved out of my artwork. These work great to make sure the paint you are pouring back in the bottle is free of any debris.By the way,the paint cleans up easily from the funnel.

So the paper filters/funnels work well. No complaints there, they do the job, and are a pretty good deal. The silicone holder funnel was one of the reasons I bought this item. I needed something to hold the paper filters. The way it was described, the two fit well together. They don't. The angle of the silicone funnel is much steeper than the angle of the paper ones, and so it holds it awkwardly, and in my case, requires thorough cleaning after each use to prevent contamination of the material that's already filtered through the paper cone. I'm not comfortable loading up the paper filter funnel and waiting for it to filter through because now there's the possibility of collapsing the silicone funnel and spilling everywhere. So basically either find another use for the silicone funnel or be ready to baby it and clean it after. But the paper funnels work as well as you could expect. I just wish they fit more like an insert than two products tossed together and not really checked.

I got these for a boat project, not thinking about how thick gelcoat is. I ended up using them to strain my acetone so I could reuse it for cleaning my spray gun. The screens held up fine to acetone and seem really sturdy for being so fine. I like the little collapsible funnel. I may end up using that for a bunch of other things.
