I have been buying this specific filter for several years and usually change it every 2 months without it being visibly dirty, and in the summer every month. But this year it got dirty quickly and eventually had a water problem, with high nitrates, so we now have to buy bottled water.

I started using the same filter again even though the water is certified by a laboratory to be absolutely drinkable.

Really good filter! Noticeable improvement in the taste of the water, while in terms of filtering it is "so-so"! Cleans on one hand, doesn't "choke" the water pressure on the other.

It has replaced the polypropylene filter with an activated carbon one and I am very satisfied with both the water quality and the fact that it has not affected the flow

Excellent filter does what it promises without reducing the water flow. I had also tried another filter with 5 microns but it reduced the water flow so much that it caused problems with the pump's operation.

I tried it, it did have a slight difference from tap water without a filter. Pretty good!
P.S. The best water I have ever tasted is from a mountain directly from the source
