Frequently Asked Questions
What does “RO” mean, and why should I care?
“RO” stands for Reverse Osmosis. It’s a water purification that removes impurities. If you want clean, great-tasting water, an RO system is the way to go. These systems can remove up to 99% of contaminates.
Countertop vs. Under-Sink: Which system is right for my home?
Countertop RO systems are portable. Under-sink systems require installation but are hidden and often have larger storage tanks.
How often do I need to replace the filters?
Filter replacement depends on the system and your water quality. Generally, you’ll replace them every 6-12 months. Check your system’s instructions for specifics.
What is the “pure-to-drain” water ratio, and why is it important?
This ratio tells you how much water is purified compared to how much is wasted. A 4:1 ratio means for every 4 cups of purified water, 1 cup goes down the drain. A efficiency ratio is better for saving water.
Do these systems remove all contaminants, including lead and PFAS?
These systems are equipped to handle lead and PFAS, ensuring your water remains pure and safe for use. The efficiency depends on the quality of water, which means depending on your water you will need to regularly check your water, and change out your filters regularly to ensure continuous efficiency.
