Whisper Bio-Bag Refill Cartridge

Got it on line,alot cheaper,plus they don't carry it in the store.

This is the best price EVER!!!! I work at a pet store and I've found them to be too pricey. I happened to stumble upon them on this site and I'm soooo happy. We all could save a little money and buy them from Walmart.com!!

Have been using this product for years. After shopping the Internet for this product I found the best price at Walmart on line. It was delivered site to store in a timely manner. I will use this service in the future.

The replacement filters cleard up my water within an hour after installation. The value ended up being less than $1.00 per replacement. Good quality and deal.

The bio-bag filters are great, especially if you are sick of the filters which are disposable and can't be reused. With these filters, you can wash them out and reuse them at least once, if not two or three times before they are completely worn out, and you can add carbon if you need to. They also are better for the environment than the disposable "one use" plastic type filters, because with these, after they are worn out, you take out the plastic insert, and throw away just the cotton type filter media and reuse the plastic insert in the next filter. Less plastic in the landfill, and on top of all the previous positives, these filters are WAY cheaper than other filters out there. Just make sure these will fit in your filter, because a lot of the filters will only take their specific brand name filters. If not, you could always get a Whisper filter, which these are actually made specifically for, and they are fairly inexpensive.
