I change the filter often. I cut it in half for my purifier and am happy with this product. I wish I could count on purchasing it in a nearby store, but that is not always the case, so on-line ordering is my best solution.
This air filter, Bplus, is twice the length as B which is Not made anymore. The filter is folded upon itself so if you unfurl it, it's twice the size and thin. You may have to cut Bplus to get fit into the space for a B for your air filter. Strange how the company didn't just make a Thicker filter in the proper size of the original B filter instead of making a long mesh filter then folding it upon itself. You have No other choices since the B filter is no longer made. Otherwise, it works.
There is a difference between B and Bplus. Bplus is twice the length as B. You may have to cut or fold over the Bplus to get it to fit into the space for a B. Something to keep in mind as you shop for your replacement - look closely to see whether you need B or Bplus.
