FAQs About Under Sink Compact Reverse Osmosis Units

The reverse osmosis process filters water through a semi-permeable membrane, separating contaminants from clean water. Multiple stages of filtration enhance the purification process.

Is it necessary to have a water softener in addition to a reverse osmosis system?

While the reverse osmosis unit handles many impurities, many owners choose to install a water softener system to address hard water issues, especially in areas with mineral-rich water.

Typically, filters need replacement every 6 to 12 months, depending on the water quality and usage. Regular maintenance checks can help determine the appropriate schedule.
