Spare filter for the Platypus Daycare.
Original spare part.
Along with use, the hollow fiber filter accumulates hard-to-remove material, slowing filtering down. And if your filter has ended up freezing when wet, you should also get a new one. This original filter fulfills the requirements of EPA and NFS, filtering 99.9999% of bacteria, and 99.9% of protozoa (including Giardia, cryptosporidium, E. coli, salmonella and cholera). Easy to clean by shaking the bottle, when the filter is installed.
