Excellent!
"Fantastic product - highly recommend. I use it all the time. It’s a proven product to purify water to a high standard. I initially purchased a different type of filter from another company and sent it back as small print said they added silver to the water! Also Dr Rhonda Patrick’s podcast on science lead health and longevity (her podcast on exercise and cancer protection is so interesting! ) also recommends reverse osmosis as the best way to purify water. I recently read a government document that states pipework for water across private land isn’t guaranteed for safety. Prior to the 1970’s lead pipes could be used; be sure to check yours!"
