A reverse osmosis system works by forcing water under pressure through a semi-permeable membrane, which removes impurities and contaminants. The clean water is then stored in a tank for use, while the contaminants are flushed down the drain. 


How does a reverse osmosis system work?

Utilizing a reverse osmosis system provides numerous benefits such as improved taste, odor, and appearance of water. It effectively removes harmful contaminants like lead, chlorine, and bacteria, providing you with cleaner and healthier drinking water. 


What is the benefit of using a reverse osmosis system for water filtration?

The frequency of filter replacement in your reverse osmosis system largely depends on the quality of your water and the amount of usage. However, as a general rule, pre-filters and post-filters should be replaced every 6-12 months, and the RO membrane every 2-3 years.


How often should I replace the filters in my reverse osmosis system?

Yes, a reverse osmosis system is highly effective in removing fluoride from your water. It can remove up to 95-97% of fluoride, making it a preferred choice for those looking to reduce their fluoride intake.


Can a reverse osmosis system remove fluoride from my water?

Absolutely! Water purified by a reverse osmosis system is safe and healthy to drink. It removes harmful contaminants while retaining beneficial minerals, providing you with clean, fresh, and healthy drinking water.
