Reverse Osmosis FAQ
What is Reverse Osmosis?
First, it’s important to understand what regular osmosis is. With regular osmosis, a diluted solution flows through a membrane into a more concentrated one. As the name implies, reverse osmosis takes the same natural process that occurs in every cell-based organism—plants, animals, and even people—and reverses it. It requires an external force or pressure to work. The high-pressure water will allow a highly concentrated solution like saltwater to pass through a membrane to a lower concentrate solution.
Comparing Stages of Reverse Osmosis Systems
Regardless of your choice, Spencer’s reverse osmosis systems are designed to provide your home with cleaner, safer water you can rely on. If you want an endless supply of reverse osmosis water or a smaller compact design that can connect to any water line, we can help you find the best water filtration system to fit your needs.
Carbon prefilter: An activated carbon prefilter reduces elements that cause water to taste and smell unpleasant, like chlorine. The carbon prefilter removes chlorine to protect the RO membrane. RO membrane: The RO membrane filters out dissolved solids, including radium, lead, arsenic, and many others. Carbon postfilter: Stage 3 is a second activated carbon filter that polishes the water to make sure it's crystal clear.
Sediment prefilter: A sediment prefilter screens out dirt, sand, rust, and other microscopic particles 15 times smaller than a grain of sand. Carbon prefilter: An activated carbon prefilter reduces elements that cause water to taste and smell unpleasant, including chlorine. RO membrane: The RO membrane filters out dissolved substances, including radium, lead, arsenic, and many others. Polishing filter: The polishing filter is a second activated carbon filter that polishes the water to make sure it's crystal clear.
Sediment prefilter: A sediment prefilter screens out dirt, sand, rust and other microscopic particles 15 times smaller than a grain of sand. Carbon prefilter: An activated carbon prefilter reduces elements that cause water to taste and smell unpleasant, including chlorine. 2nd carbon prefilter: Another activated carbon prefilter reduces elements that cause water to taste and smell unpleasant, including the taste and odor of chlorine. RO membrane: The reverse osmosis membrane filters out dissolved solids, including radium, lead, arsenic, and many others. Polishing filter: The polishing filter is a second activated carbon filter that polishes the water to make sure it's crystal clear.
Stage One Sediment Filtration Sediment reduction to 1 micron; 40 times smaller than visible to human eye Stage Two Ultra Pre-Filtration ½ micron carbon filtration has highest chemical absorption rate of any similar dimension carbon block filter. The best in RO Membrane Protection! Stage Three High Flow Eco Membrane Encapsulated thin layer composite (TLC) membrane produces 50 GPD of purified water. Double the recovery of standard membranes. Ultra-efficient, filters down to the molecular level to remove total dissolved solids (TDS). NEW TECHNOLOGY! Less waste, faster production Stage Four ECT™ Filtration This design feature extends the water contact time with the carbon 60 times longer than our competitors, thus doing a better job of reducing contaminants. Reduces contaminants that other RO systems miss! Stage Five Remineralization Filter Adds minerals back into the water and helps to increase the pH of the water. Stage Six Polishing Filter Water passes through a specific coconut carbon blend flavor filter to ensure the best-tasting water.
6-Stage Reverse Osmosis Systems
Designed for harsher water conditions with higher production needs. Stage Four ECT™ Filtration: This design feature extends the water contact time with the carbon 60 times longer than our competitors, thus doing a better job of reducing contaminants. Reduces contaminants that other RO systems miss!
5-Stage Reverse Osmosis Systems
Your body is 70% water! You need water, its a fact. Especially those who dwell in desert climates. By drinking purified water, you’ll reduce the contaminants that are pumped into your system. Plenty of water helps maintain your metabolism and cleanse your body of impurities.
4-Stage Reverse Osmosis Systems
Designed for harsher water conditions with normal production needs. Our system delivers water up to twice as fast as others with a special brass and lead-free design. Water conservation shut-off can save hundreds of gallons of water each month over other systems.
3-Stage Reverse Osmosis Systems
3-stage systems, are less stable, more problem-prone, and require more frequent filter replacement (every 4-6 months). Generally, RO systems at the lower price range (below $200) are of lesser quality. We do not recommend them because of their frequent problems and shorter life-span. RO systems at lower prices are mass produced using mostly low quality components that crack and leak easily under pressure and over time. Of course, price should not be the only consideration because there are poor quality systems with high price tags. Very much like cars, there is quite a difference in the quality of RO systems although they may look similar or even identical to each other.

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.
