I knew when buying these products that I was investing in my health. Yes, they are more expensive than others on the market, but these are legit. No more lugging 5 gallon jugs up flights of stairs to my apartment! The Sans water tastes just like the purified, reverse osmosis water I would get from the grocery store. I love the hot water feature, too- it's actually HOT! My only complaint is that the water tank isn't that big (and kind of awkward to take out if under a cabinet) and to empty out the remaining water every time seems like a waste- we keep a jug and use that water to put in our pool, but I get the whole 'no residue remaining' point... The air purifier is amazing. It is so fun(?) to see the numbers/colors change on the screen as I am cooking or even spraying home fragrance- who knew those were so toxic??!! And on the auto-mode, I don't even have to worry about it- it is so quiet. Overall, greatly impressed with both products- customer for life!
