SunSun HW-304B HW-404B HW-704B Filter Pack Set

To begin with the Filter Works excellent that the filter pads go to it is never not work correctly the shipping of the pads was rather quick then expected to come so fast the price for the pads is excellent and the Machine that goes to is amazing without question probably one of the better ones I've ever bought when it comes to aquarium canister filters this filter and its pads top of them

These are amazing. So durable, I have already cleaned them by squeezing it several times. Does not lose its shape and fits smoothly right back.

I bought these for an Aquatop CF500 UV. They fit fine and seem to be of adequate quality. I've cleaned them once and they seem to be holding up well.

Ordered from Tech n Toy, and these pads work great. Within one day of adding them into my 304b canister filter my cichlid tank has become much more clear. These canister filter direction is bottom up so the coarse and one fine filter pad went on the bottom rack.

Amazon should really stop selling things that can vary in quality from the 3rd parties. At least they shouldn't sell it under the same item unless they make sure that their quality is consistent across all these different "companies" that are providing amazon with products that amazon then ships to people. Bought these in November and was very happy with what I got even though it didn't fit my HW-402B SunSun filter. Wasn't a big deal. I just cut these pads and they worked fine. The seller at that time was CK Aquatic Works. I'm still using the blue filter as a mid density one (wasn't coarse though) and will probably use it for another 6 months. However, the white ones have been good for about 2 months a piece. I loved the white ones even though they don't last much because they were pretty thick and high density. They did a very good job at filtering small particles.Now, I order this same pads again because I wanted more white pads. They are listed as the same item, but their quality is completely different. The seller this time was Monster Pets. The white pads are much thinner than what I got the first time and the blue pad is completely useless. I think the blue pad that I got this time might be the same white pad colored with blue paint. It's just unusable. I will not be ordering these again.

we received it on 8-7-2013 and placed them in the filter they fit and they work great well worth the money

The coarse pad was NOT included, and the white pads are pretty flimsy/thin. They do fit my Sun Sun canister just fine.

These fit the exact model of Aquatop I have. They were a perfect fit.... the CF500 w/UV, just so's everyone knows. The only thing I could find to complain about is the blue "course" filter seems to be the same as the white ones, just blue. The original blue "course" (bottom layer on the aquatop pictures) is actually supposed to be a sponge plastic/rubber like material, not just another floss filter. BUT... considering the price, 4 floss replacement filters for around $5 ($20 at my neighborhood pet store) it doesnt seem fair to complain. I'm thinking the original one should last forever anyway.
