What is Reverse Osmosis?

Fresh, clean water can make a world of difference when it comes to your home’s water supply. From laundry to your drinking water, the average Arizona household uses about 120 gallons of water each day. With a reverse osmosis water filtration system, you can be sure the water your family consumes is free of minerals and contaminants. At Spencer’s, you’ll find a whole house reverse osmosis system that will work for your home. Whole house RO systems are designed to treat water at the point of entry, so the system is installed where your water line connects to your home, that way you can be certain all the water you and your family uses is clean and pure. We’ll get more into how a reverse osmosis system works, but the basics are that it cleans your water of most contaminants and dissolved solids. Do keep in mind that an RO system will not remove bacteria — but if your water comes from a city treatment plant, it should already be safe.

How Does Reverse Osmosis Work?

The big questions: What is reverse osmosis and how does reverse osmosis work? The answer may be a little complicated, but our water treatment specialists are here to help.

Reverse osmosis is a process by which contaminants are removed from your water, making it cleaner for you to drink, shower with, water your garden, and wash your clothes. The process works by using a high-pressure pump to increase pressure on one side of the system, pushing water through a membrane, which leaves 95% to 99% of dissolved salts behind. Instead of trapping the rejected materials like some filters, a reverse osmosis system drains away the rejected salts and contaminates.

First, using a prefilter, a reverse osmosis system takes out sediment and chlorine from your water. It then pushes water through a membrane that only allows some material through, thus removing dissolved solids. Next, water passes through a postfilter to do a final clean before the water is sent to a faucet. We offer 4-stage, 5-stage, and 6-stage reverse osmosis water systems. The higher the stage, the more filters your water passes through before you drink it.

What Does a Reverse Osmosis System Remove?

A reverse osmosis water filtration system removes contaminants from your water. These contaminants include:

Fluoride

Salt

Sediment

Chlorine

Arsenic

VOCs*

Herbicides & pesticides

And more

*volatile organic compounds such as paints, cleaning supplies, glues, ink, etc.

We should reiterate that a reverse osmosis system will not remove bacteria, as it is designed to remove dissolved solids. The reverse osmosis process is designed for potable water sources.

How Can a Reverse Osmosis System Benefit You?

If you’re wondering if a reverse osmosis water filtration system could benefit you and your home, we can tell you without a doubt that yes, it absolutely can. Our Envirotec water filtration systems, which are exclusive to Spencer’s TV & Appliance, are designed for the harsh hard water conditions of the Arizona desert. We have over 35 years of experience treating Arizona hard water conditions in homes, and our process and quality products have only gotten better.

With an under sink reverse osmosis system, you’re giving your family bottled-water quality drinking water that they can enjoy year-round. Thanks to our dedication to clear water, we’ve been able to create the best reverse osmosis system for Arizona residents. By removing dissolved solids from your drinking water, a reverse osmosis system eliminates the need for a separate water filter in your fridge or attached to your faucet. So, when you need to find a reverse osmosis system for home use, Spencer’s and Envirotec should be the only names on your list.

How Do You Maintain a Reverse Osmosis System?

Regular maintenance of your Envirotec reverse osmosis system is necessary for maintaining clean water. For your reverse osmosis system to continue to work properly and for all the filters/membranes to continue to filter our contaminants, we recommend maintenance every six months. Our Envirotec reverse osmosis drinking water systems are not only of the highest quality, but they are also backed by the best warranties in the industry. In fact, many of our Envirotec systems are backed by a Limited Lifetime Warranty on major components. However, we have found over the years that it is not uncommon for an Envirotec water softener to last 10,15, even 20 years without trouble. You can be sure your home will have cleaner, healthier water for years to come with our warranty coverage. For more information about what our warranties cover, please visit or call your local Spencer’s.

Reverse Osmosis Frequently Asked Questions

What is a reverse osmosis system?

A reverse osmosis water system is a water filtration system that is attached under your sink. It filters out dissolved solids, chemicals, salts, and other contaminants, making your drinking water fresher and cleaner. They do not filter out bacteria, however, so these systems should only be used with potable water sources. For more information, refer to our reverse osmosis diagram.

How much does a reverse osmosis system cost?

We have an under sink reverse osmosis system that will work with your budget. With 4-stage, 5-stage, and 6-stage systems to choose from, you can be assured that your family will be drinking the freshest water possible at a price that will agree with your wallet.

How to install a reverse osmosis system? (Envirotec does all installations for those who buy their product)

You don’t have to worry about installing your own reverse osmosis system. At Spencer’s, we install Envirotec filters for all our customers. If you want a whole house reverse osmosis system, consider one of our whole home water softener filters. These are not reverse osmosis, but we can additionally install RO systems under any of your sinks. These can also be found in bundles.

Do all reverse osmosis systems remove fluoride?

A reverse osmosis system does indeed remove fluoride from your water! Along with other chemicals like paint, paint thinners, salt, and dissolved solids, a reverse osmosis system will purge fluoride from your water thanks to the filters. So, with a reverse osmosis drinking water system you can get the purest, water bottle-quality water.

Does a reverse osmosis system remove chlorine?

Yes! A reverse osmosis system will remove chlorine from your water. For this reason, we do not recommend a reverse osmosis system for your pool as it will remove necessary chemicals that clean your pool water. RO systems are better served under sinks and where you plan to drink your water (they’re also good for refrigerators and ice makers).

Do I need a reverse osmosis system?

A reverse osmosis system for home use is the best way to get water bottle-quality water in your home. For drinking purposes, a RO system will remove contaminants that are potentially hazardous, giving you drinking water that will be clean, fresh, and delicious. We recommend reverse osmosis systems to anyone who wants to reduce their plastic use (water bottles) and get the freshest drinking water.
