In the first replacement of the crystals, water leakage appeared where the blue cap screws on. I tried to solve it with insulation tape, but in vain. I threw it away.

Yesterday, 15-07-22, I did the first wash with whites. I am on an island... you understand what kind of water we're talking about! END! THIS IS THE SOLUTION... unrecognizable towel. I had them folded and they were like glass paper! It's not feather... but it's a towel! As for the lifespan, the cleanliness of the water, how hard it is or not, must also play a role! I will come back!

I haven't used it enough to know the result, but I believe it's worth a try. Besides, the cost is very low and be careful to only use it in the dishwasher, never drink water from this filter

A mediocre product that theoretically does its job so far. One of the disadvantages is that its duration is shorter than what is stated in its specifications.
