Is RO Water Safe to Drink?
The short answer is absolutely YES. For a more in-depth answer to this question, check out my post titled “Is RO Water Safe to Drink?”. Most of the concerns I’ve heard about drinking RO water revolve around the fact that all of the minerals have been removed, which could lead to mineral depletion in our bodies. While there is a shred of truth to this, the concern is significantly outweighed by the benefits of drinking pure, clean water. Also, many of the systems we have reviewed have re-mineralization steps built in. If you chose a system without a built in re-mineralization step, one can easily be added to your home.

FAQ Section
What is Reverse Osmosis?
Reverse osmosis (RO) is a water purification process that removes contaminants from water by using pressure to force water molecules through a semipermeable membrane. This technology is effective at reducing a wide range of contaminants, including dissolved salts, bacteria, and chemicals, making it a preferred method for producing clean drinking water.
Can I Install an RO System Myself?
Yes, many RO systems are designed with DIY installation in mind. Basic plumbing skills and a few common tools are typically all that’s needed to set up an RO system. Manufacturers often provide detailed instructions and support to assist homeowners during the installation process.
How Often Do I Need to Replace the Filters?
The frequency of filter replacement depends on the specific RO system and the quality of the input water. Generally, pre-filters should be replaced every 6 to 12 months, the RO membrane every 2 to 3 years, and post-filters every 6 to 12 months. It’s important to follow the manufacturer’s recommendations to maintain optimal system performance.
Does an RO System Waste Water?
RO systems do produce wastewater, known as brine, due to the nature of the filtration process. However, advances in technology have significantly reduced the amount of waste produced. Some systems now offer improved efficiency with lower water waste ratios, and there are also ways to repurpose the wastewater for non-drinking purposes, such as gardening or cleaning.
