Best thing we’ve done in a long time !! The water quality has changed significantly for the better. Most importantly the drinking & cooking water quality has improved dramatically, as well as water for showers, laundry, dishes etc….

We always knew it was pretty bad, but we didn’t realise how bad until we added the filter”
