Researching a new system was a right-old long rabbit hole with so many systems claiming healthy filtration but on reading up on Reverse Osmosis not being great for the body took the advice of a health expert (Ari Whitten/The Energy Blueprint) who is 'Mr Research' as far as I'm concerned, so in-spite of being financially challenged at this challenging time I plumped for the Ultra-UC and no regrets so far although expensive for us in the UK by the time you add shipping and customs and fitting (unless you're flushed!)
Igor was thankfully very efficient / obviously knowledgeable and very helpful. Thank you!
