We are doing a renovation and we are putting in a long-wanted water softener (we’re in London and the water is awful, limescale etc - I’m originally from a country with lovely water and have never got used to the hard water!). The contractor has suggested a salt free water softener (Aquatiere EAU2 Pureau Whole House Filter & No Salt Water Softener + Drinking). I’m hesitant to get a salt free system as I’ve read they aren’t as good - but I have no experience with water softeners in general). Can anyone advise on this?? Or recommend a water softener? Thank you!
