How RO Works
1. Reduces large particles
Water first passes through a sediment filter that catches dirt, dust, and rust. Then, a carbon filter reduces chlorine and other chemicals.
2. Purifies water through the RO membrane
The RO membrane filters out dissolved salts, lead, mercury, calcium, iron, and other harmful substances. It lets only pure water molecules through, leaving the contaminants behind.
3. Improves water taste
Before the water reaches your faucet, it goes through a post-carbon filter to reduces any remaining bad tastes and odors.

Tank RO System
Water is filtered and stored in a tank. Once the tank is empty, you'll need to wait for it to refill before you can get more water. The tank can take up significant space and may become dirty over time. Imagine you're halfway through preparing dinner, and the tank runs out. Now, you're stuck waiting for it to refill. Plus, that bulky tank takes up valuable kitchen space, and regular maintenance is a time-consuming hassle.
