Fisheye Minnow-Ersatzkartusche

No telling exactly when you will need to replace the original cartridge it comes with but why get caught without having them when you need them. The fact you get several is also and added benefits. Love the minnow and trust it fully.

First, youll need a MINNOW FISHEYE FILTER CARTRIDGE HOLDER to put these babies in. So make sure thats in your cart.
Now the review. Are you familiar with the FISHEYE in-line (full size) filter and its membrane? Same stuff here, just a smaller size. Unlike fabric filtration (IE cigarette butt type filter fabric) this filter membrane material entrap particles of micron size. The filter material loads up on the gunk while not limiting air flow until the filter medium reaches a point of total saturation. At that point they stop air flow. Hence the need for replacement cartridges. Ive read to replace every 30 days, but they say that about AC filters too. Just buy a couple of packs of replacement filters and be ready.

Must have item if you get the filter ...if one little cartridge replacement gets saturated with moisture I just replace it and keep my same momentum. No hesitation!! I love these replacement filters
