Great product. Arrived quickly

Bought them to hold Heartfelt beads for the humidor and they work well. I wish they closed a bit tighter but they mostly work.

Bought this to put purigen in for my aquarium. Bag is a little longer than I expected. It ties securely and no purigen escapes into my water.

I'm surprised how fine the filter is for filtering. It worked great for what I needed it for; however, my little experiment ended up somewhat in a disappointment for me. I had rigged up a previous and out-of-date water pitcher that I had which takes those really cheap water filer, and I managed to fit the extra fine filter into the hole where the water filters normally goes for filtering, and I added activated carbon to it and overfilled it so there was bulge of activated carbon above the filter hole. The setup was perfect. However, the water went through the activated carbon really fast. It only managed to filtered out 10 TDS in the first pouring. I guess if I continuously refilter the water, it might bring the TDS level down somewhat. But the extra fine filter will definitely prefilter large debris in the water such as very fine sand. When I added the activated carbon to it and pour water to it for the first time, very fine powdered carbon came out of it which is normal on the first flush. Thereafter, the water was very clear. I guess if I used it for a fish tank, it would more than likely make that water crystal clear because of continuous filtering. The reason for the rig-up was I trying to make my ZeroWater filter last longer so it didn't have to work so hard in filtering. Those ZeroWater filters are extremely expensive yet it is the best water filter I ever used.

works well for its purpose

Nice little bags. I use them on my nuvo fusion 15 saltwater aquarium. I got rid of the filter sock and upgraded my metia basket. Got some of these little bags fit in quite nicely. Definitely recommend them

These are good quality bags with good stitching. Works with Purigen.

Cumple con el objetivo por el cual lo compre, para usarlo con purigen

I use 2 of these bags in each of my filters ,, really good quality and fits heaps of bio in

la ocupe para colocar el matrix y en otra para la resinas el poro es muy pequeño que filtra de manera perfecta.

Arrive promptly, well packaged. Well finishd & looks sturdy, but I haven't used it yet. I have the Grayl water bottle, which absolutely excellent for everything Bad for Personkind, BUT, its impotent for water with tannins which is the same for the Steripen
