Reverse Osmosis System FAQs

Like many consumers, you may know that a Reverse Osmosis System is a water treatment system—but that’s about it. This article has been written to help give you a better understanding of what a reverse osmosis system does and how it works. Below, you will find some of the most frequently asked questions regarding reverse osmosis systems.

What does a reverse osmosis system look like? Where is it kept?

A reverse osmosis system is a compact unit installed underneath your sink or in basement, in some cases, on the countertop. Typically, a reverse osmosis system includes a pre-filter, a reverse osmosis component, a post-filter and may have other polishing filters and a holding tank.

How does a reverse osmosis system work?

The pre-filter traps contaminants like chlorine and unhealthy bacteria before they reach the reverse osmosis membrane. The reverse osmosis membrane, then isolates these contaminants before the water continues to the post-filter component. Finally, the post-filter gives your water one last polish before it flows to the holding tank, which provides the fresh and clean water that runs out of your faucet. The wastewater is sent down a different line into the drain.

How do I maintain my Reverse Osmosis System?

In order to ensure your Reverse Osmosis System is working to the best of its abilities, it is important to change your filters on a regular basis. As a rule of thumb, your filters should be replaced every six to eight months. The “correct” time to change your filters varies, however, depending on your local water conditions and the manufacturer’s recommendation. The reverse osmosis membrane component of your Reverse Osmosis System will need to be replaced every three to five years (again, this depends on the quality of the water being filtered).

How effective is a Reverse Osmosis System?

A Reverse Osmosis System is extremely effective in reducing the amount of contaminants in your water. The reverse osmosis membrane in your Reverse Osmosis System has very tiny pores, which allow pressurized water molecules to pass through contaminants. Reverse Osmosis Systems can almost rid or reduce your water of a variety of contaminants including: aluminum, arsenic, asbestos, chlorine, copper, cyanide, fluoride, lead, mercury, nitrates, sodium and more.

Who should get a Reverse Osmosis System?

A Reverse Osmosis System can help treat water with taste or discolouration issues.
