What Is Reverse Osmosis and How Does It Help?

A whole house reverse osmosis system pushes water through a membrane that removes minerals, chlorine, sediment, and other contaminants. This process gives you consistently clean, filtered water throughout your home.

Many Central NJ homeowners choose reverse osmosis systems because they improve everyday tasks and drinking water tastes fresher. Showers will feel better and laundry comes out cleaner.

If you want water you can trust, a reverse osmosis system offers a dependable, long-term solution.

What Is Reverse Osmosis (RO)?​

Reverse osmosis is a natural process that occurs in every cell-based organism. During this process, a solution is placed under pressure and sent through a membrane. This membrane allows smaller particles through while trapping the larger ones (large particles are often contaminants). Once the process is complete, the higher concentrations of contaminants are found on one side and the freshwater is on the other side.

Is Reverse Osmosis Water Safe to Drink?

Yes! A whole house reverse osmosis drinking water system delivers cleaner, safer water throughout your home. Its RO membrane removes contaminants that standard filters often leave behind, so every faucet provides higher quality water.

Because the system treats water at the source, it improves cooking, drinking and bathing. It also protects your plumbing, reduces buildup and helps appliances run more efficiently. With cleaner, consistent water in every room, your home becomes more comfortable and easier to maintain.

Got an estimate in 1 day and install 2 days later. Everything was amazingly smooth and effortless and our new system is fantastic. Love our new thermostats too. We were very pleased, especially right now when people are having so many problems getting supplies and equipment. Already recommended to neighbors.

Professional & Friendly

Truly great service! He was professional & friendly. He is clearly experienced because he installed a water-pressure sub pump backup system for us which is a complicated job. He came back again a couple of days later to replace an old leaking toilet. He was considerate with cleaning up afterwards too. I highly recommend Guaranteed Services & especially Rob.
