WOW What a Deal! 11/7/2013
I shop at 2 major pet stores in NJ and those companies have been ripping people off for years. I've been using whisper products for 20+ years and I'll be shopping here more often. Just imagine same product in my local store for $14 and here its $9. why? And your cheaper then walmart lol

I have used these for many years and they still work good not as sturdy as they used to be but then again everything today doesn't last anymore

I've been using Whisper Bio bags since 1999 in my whisper junior filter. I now use these bags in both my Whisper 60 and my whisper 20 filters:yet this one size works in both the size filters. They are easy to use. Take out the old one and insert fresh carbon into the new one. After a quick rins insert in your filter. There are no moving parts;nothing to deal with. Of course, you can spend a little more and get the bags assembled with carbon in each one. Your choice, but really nothing difficult when handling these bags.
