As a filter for a Dafi jug, it's ok. For Brita, which I initially bought, it doesn't fit, at least in mine. If the jug has a kind of plunger under the point where the filter attaches, don't buy it. Always go for Brita!

I use it exclusively for filtering water from a mountain spring. It is a reliable, high-quality, and cost-effective solution. The sad thing is that we have come to filter even the water from springs due to the unreasonable use of pesticides and heavy fertilizers.

One piece at 7+ euros is not cost-effective at all compared to other filter solutions. The three pieces at 13+ euros are better, but still more expensive than other solutions since the filter needs to be changed approximately every month.

From economy to ecology. Similar situation, definitely much more environmentally friendly than buying water bottles, but due to the relatively frequent filter change, there are more ecological solutions.

Nevertheless, it is something convenient and easy to use. You pour water from the tap into the top part of the jug and in a short time (about 1 minute) it has filtered it and is ready for use. Changing the filters is also easy without any special tools. The taste of the water is better, now how well it does its job can only be determined by chemical studies.
