Those are actually kind of nasty. If you want a drinking water only filter, any carbon filter (and they are all carbon) is fine. Britta, etc. All the same filter media. A RO has several stages of filters including a carbon filter, then the water is forced through a reverse osmosis membrane, picture a roll of saran wrap. It makes one gallon of filtered water to 3 gallons it wastes and that gallon is stored in a pressure tank. Like a miniature well pressure tank. When you tap the water, it goes through a final carbon filter to get rid of any taste is picked up in the tank (a kind of rubber taste from the rubber bladder). Keep in mind, that water sits in that tank and is not sanitized. All the chlorine has been removed and the water can get to room temperature unless you go through a lot of it. A lot of bacteria can grow in that tank. Also, completely de-mineralized RO water is not good for you. Look it up. I would not have an RO in my house but, many people love them. The water will not taste good. It has a very flat taste.
