Fits all my aquarium inlet/ output canister filter system. Catches all of the floating debris/ detritus ; keeps the tank water clean/ clear . I use them too for my carbon media !They are sturdy and just the right size I need .Thanks!!

Good filter bags for the cost.
The AQUANEAT filter media bags are a solid choice for most types of filter media. Made from durable, fine mesh material, they work exceptionally well for holding biomedia, carbon, crushed coral, and similar materials. I’ve been using them in two freshwater canister filters and a saltwater sump for Bio-Home media and carbon, and they’ve performed reliably. They’re easy to rinse, reusable, and hold up well under regular use—making them a great option for long-term aquarium maintenance. That said, the mesh is slightly too large to securely contain finer materials like Purigen. While this isn’t a major drawback, those specifically seeking bags for finer media might want to look for options with a tighter mesh.

They do what they are supposed to
Recently just took the tank apart I used these in and they worked perfectly. Probably been in there for a few months and no sign of decay. Pretty easy to use if you know what you are doing since they are just bags. Holds my plants well and to pry them off and was able to reuse the bags just replenished the aqua soil.

Slightly smaller than expected
Size: 3” x 4”
These bags have a very fine mesh that works well for adding crushed coral to my canister filter. Although they were slightly smaller than expected they seem to be well made and the zipper works well. Not sure how well the tag will hold up, so I will probably trim it as close as I can without cutting the stitching.

Great Tiny bags!
Size: 3” x 4”
These are great tiny bags that I’m using for carbon and biofilter in my 10 gal tank. I am hoping they will be reuse able at the end of a few weeks. The zipper seems like it’s going to hold up. They each have a manufacturer tag on them that I cut off, had no idea how that would hold up in water and didn’t want to take a chance of it disintegrating. A good buy so far!

Good Medium Bags. I would buy them again.
Size: 3” x 4”
I use them for a couple types of medium and have had no problems. I would buy them again.

Not 3 × 4"
Size: 3” x 4”
The first photo showes the filter bag stretched in both directions with straws cut to fit tightly. It can make 3" wide but I could not stretch it any more than 3.5" high. The second photo showes a 4" straw trying to fit vertically but it could not. You will notice the straw is not straight up and down and you won't notice, but the straw folded it's self 1/4" shorter at the top to get it even diagonally into the filter bag. The third photo shows a 3" straw horizontally in the bag. It still manages to fit at the maximum width of the bag. So, as far as i can tell, it is maybe a 3×3.5" bag when stretched flat. However, if you plan on putting anything in it, the demensions will shrink. Otherwise, it seems reasonably well made and has a good zipper. I have not used it because it's too small for what I planed, but I think I can make do by leaving part of the pump outside the bag and fitting the filter around the water intake.

Birdbaths and Fountains
Size: 3” x 4”
These are inexpensive and good quality so far. I bought these to put in each of my outdoor fountains and birdbaths with mosquito "dunks" inside them. Haven't seen any mosquito larvae since then. Since you can see through the mesh I always know when to replace the dunks but really these are cheap enough to even be used as disposable. Also, the mesh is small enough to keep the dunk granules from clogging the filters in the fountains.
