Filter cartridge can be a
Filter cartridge can be a hit or miss
I have ordered two replacement filters so far. Both of them died prematurely (lasted for less than 2 months). In both cases Hydroviv kindly sent me complimentary replacements which lasted for a bit less than 6 months. That makes me wonder if the replacements I ordered have subpar quality than the ones that were sent as warranty.
But that is also the last time Hydroviv is going to send anymore warranty replacements. I will try them for one last time if it doesn't work, I'll switch to other brands.
