Is an Under-Sink Reverse Osmosis System Worth It? Benefits, Costs, and Drawbacks
Carbon filters can make your water taste and smell better, but with RO you are getting much, much cleaner water than what that inexpensive Brita filter can muster. (That said, RO can’t capture everything, and carbon filters are still useful for capturing certain volatile organic compounds through adsorption. Most RO systems also have an additional carbon filtration system included.)
Note that two types of RO systems are available: Tanked RO systems filter water slowly (albeit passively, without electricity) and sequester it in a (rather large) tank under your sink. Today, tankless RO systems are more popular, processing water on demand but requiring electricity to keep things flowing expeditiously. Tankless systems are considerably more expensive due to their inherent complexity.
