SUPER cheap compared to pre-assembled ones!
on December 28, 2011
When ordering these I was afraid it would be a complete hassle to assemble them. Turns out it takes less than two minutes and is SUPER easy. All you do is stick the frame into the bag, pour the carbon in, clip the frame closed and pop it into your filter. Note that it comes with only one plastic frame, so when replacing you need to take it apart and save the frame. Not a big deal; after assembling this one, I took apart the pre-assembled one I was replacing and found that nothing additional goes into the assembly of the ones that are sold assembled. I was able to save the frame from that one, so I'd have an extra just in case. The same exact frame and clip are used. In light of this, the price of these is awesome. You get a year's supply (provided you need them for just one filter) for the price you'd get 2 or 3 assembled ones. Such a HUGE discount for SO LITTLE additional effort. I noticed some people complaining about differences in sizing. There is no difference, unless you're used to the different name for the sizes from a while ago. Medium = Junior apparently, and it's written on the box. But I don't see that name for the sizing of this brand at the pet store anymore. If you're currently buying the assembled medium ones, these are the ones you need to buy.
