Reverse Osmosis Systems in Waltham, MA

What it is

Reverse osmosis (RO) forces water through a semi-permeable membrane to reduce a wide range of contaminants, including dissolved solids. RO systems are usually installed under the kitchen sink and often include sediment, carbon, and membrane stages, with a dedicated faucet for drinking and cooking water.

Problems it may address

• Concerns about dissolved solids or specific contaminants in drinking water
• Taste and odor goals that a basic carbon filter may not fully address
• A preference for a dedicated, high-quality drinking water tap
• Water used for cooking, beverages, and ice

Is it right for your home?

RO is commonly chosen when the goal is high-quality drinking water and the reduction of a broad range of contaminants. It is a point-of-use system, so it treats water at one tap rather than the whole house. RO systems produce some wastewater as part of the process, and they work best with periodic filter and membrane replacement.

Things to consider

• Installed under the sink with a dedicated drinking water faucet
• Typically includes sediment, carbon, and membrane stages
• Membrane and pre-filters need replacement on a schedule
• Can be paired with a whole-house system for full-home treatment
