Very efficient, I had a doubt about the efficiency but after using it now I no longer have it :-)
Our tap water tasted like chlorine, it was hazy... Well as if by chance it came out very clear, and no more taste.
Received very quickly.
I recommend it.
Filters the water very well, it no longer has the bad taste. Very easy to use, the instructions are very well explained.
Well wrapped, well received with the necessary indications for a good use.
now it remains to try it to purify our water.
