Having access to quality drinking water can make a difference in your everyday routine. With a reverse osmosis system from Kinetico, you can enjoy the convenience of filtered water right from your kitchen.
Some of the benefits include:
Reverse osmosis (RO) is a water filtration process that uses pressure to push water through a semipermeable membrane. This membrane helps separate unwanted contaminants, allowing filtered water to pass through while rejected substances are flushed away.
Keeping up with regular maintenance helps your system continue performing as intended. Over time, filters become less effective and need to be replaced to keep your system working properly.
How often you need to replace reverse osmosis filters depends on your system, water quality and household usage. For Kinetico K5 owners, following the recommended filter change schedule and understanding how to maintain your system are important parts of keeping it in good condition.

No! The Kinetico K5 operates using your home’s water pressure, so it doesn’t require electricity to filter your drinking water.
Most homes can accommodate an under-sink reverse osmosis system, but installation requirements depend on available space, plumbing and water pressure. Our team can evaluate your setup and determine whether the K5 is a good fit.
Yes, reverse osmosis removes naturally occurring minerals like calcium and magnesium. However, most essential minerals come from the foods we eat rather than drinking water. For homeowners who prefer mineral-enhanced water, the Kinetico K5 offers a Mineral Plus option that adds minerals back into filtered drinking water.
Professional installation is recommended to ensure your K5 is properly connected and operating as intended. Kinetico of San Antonio can handle the installation and answer any questions about using your new system.
