Improving the Quality of Your Drinking Water

Water contamination is a serious problem. The crisis in Flint, Michigan, the lead problem in Newark, New Jersey, and the fact that similar situations continue to hit the headlines tell us that anyone can have dangerous contaminants in their water. Luckily, Guaranteed Service can help. Committed to your safety, health, and comfort, our technicians offer a variety of water filtration services to ensure your family has access to fresh, clean drinking water. Our Kinetico reverse osmosis water purification systems are proven effective in eliminating many common contaminants from your drinking water.

Reverse Osmosis Water Filtration

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.

What an RO System Does

To achieve fresher, cleaner drinking water, you can apply the reverse osmosis process to water filtration.

The basic functions an RO system performs include:
  • Pre- or post-filtration: In addition to the semi-permeable membrane that acts as a filter during the reverse osmosis process, RO systems often contain one or more other filters, including sediment filters and carbon-based filters. Depending on the type of system, water either passes through these filters before or after the reverse osmosis process takes place.
  • Reverse osmosis: During the reverse osmosis process, water is sent through a semi-permeable membrane, which removes up to 98% of total dissolved solids.
  • Storage: RO systems contain a storage tank that holds all filtered water until it is needed. The reverse osmosis process continues until the storage tank is full and begins again after water is used from the tank.

At Guaranteed Service, we are proud to offer a variety of state-of-the-art reverse osmosis systems in New Jersey.

Is Reverse Osmosis Water Safe to Drink?

After installing a high-quality reverse osmosis water purification system-like those we offer here at Guaranteed Service-your family will have a safer, cleaner, and more delicious supply of drinking water. This kind of system reduces contaminants such as particles, bacteria, chemicals, and minerals from your water supply that can be harmful to your health.

The vast improvement in the safety and quality of your household drinking water supply is reason enough to install an RO system, but you'll love the convenience of enjoying tasty and refreshing water straight from the tap. A reverse osmosis water purification system is a valuable addition to any home.

No one likes the idea of drinking water that is chock full of contaminants.

Fortunately, a reverse osmosis (RO) system can effectively trap many different types of contaminants, including:
  • Cryptosporidium
  • Giardia Lamblia
  • Legionella
  • Bacteria
  • Viruses
  • Chemical contaminants
  • Arsenic
  • Copper
  • Lead
  • Mercury
  • Nitrate
  • Fluoride
  • Bromate
  • Chlorite
  • Haloacetic acids (HAA5)
  • Total trihalomethanes (TTHMs)
  • Salt
  • Chlorine
  • Sediment
  • VOCs

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.

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.
