Reverse Osmosis System Buyer’s Guide

When you’re looking into buying a supreme water filter, you can either choose a home filtration system that includes a reverse osmosis treatment station, or you can choose simply to have only a reverse osmosis system. In this article, we’re going to give you some tips to make the ultimate reverse osmosis system buyer’s guide for your home so you can purchase one and know what to look for, as well as educate you in the necessary things you will need to know and look for in order to find the best reverse osmosis system for you.

What is Reverse Osmosis?

What is Reverse Osmosis

Reverse osmosis is a type of water purification that uses a form of screen or permeable membrane to filter out specific and potentially harmful items. Reverse osmosis can help to get rid of a lot of contaminants like salts, metals that seep into your water systems (lead, mercury, and iron to name a few). It also can help rid your home of possible asbestos and calcium that can enter your water system from a water treatment facility. While it doesn’t get rid of many chemicals (like chlorine for example), it can greatly eliminate any worry about having micro-sediment in your water that can be harmful or potentially fatal for your home.

Things to Think About When Buying a RO (reverse osmosis) System

You’ll need to have a separate faucet other than your main water faucet to dispense your treated water from the RO system. You can choose between air gap faucets that help to prevent drain water from seeping back into your RO system. Otherwise, you can choose a non-air faucet which is usually a lot quiet and easier to put into your home. You can always use a backflow check valve to help avoid siphoning, which is why a non-air gap faucet is the most common one installed in homes.

How Many Filtration Stages is Best?

How Many Filtration Stages is Best
Most RO systems range from three to 5 stages, but if you want to be considered completely safe, you’ll want at least a four-stage filtration system.

Water Softening

Hard water doesn’t get softer with a RO system and can actually cause deterioration of the membrane inside of it. Therefore, you may want to have a water softener installed on your line prior to it reaching your reverse osmosis system.

What About Ice Makers?

Ice Makers
There are special adapters that can easily feed to your icemaker, so you don’t have to get a different filter or unit for your refrigerator’s ice machine.


When it comes to the best drinking water, science has been proving for years (even now more than ever) that reverse osmosis treated water is actually more beneficial to your health than a regular filtration system. This is basically a science that water bottling companies have been using for years, and still use for almost every bottle of water produced to this day (most companies that even add the “electrolytes” and added minerals to the water do this after a reverse osmosis process to ensure that the water is pure and free of harmful sediments). While some places don’t require you to use this, it’s actually a great idea for homes in all different types of locations.
