(Reverse Osmosis System)
Very simple for such a wonderful product. Step by step. Easy to read instructions Manual and the taste is to die for. Not sure how I’d live without this product. Simply change the filter with the filter that came with the product and then when I run out of those they’re very inexpensive to get replacement filters. Value is great in my eyes. This product is priceless. Me and all my family love and own this product. I’m always telling people how much better their coffee and tea will taste.
