How Reverse Osmosis Works

1. Sediment Filter

The first stage of reverse osmosis is the sediment filter, which removeslarger particles like sand, rust, and dirt from the water. This improveswater clarity and protects the filters that follow. By catching debris early,it helps maintain performance and extends the life of the system.

2. Carbon Block

The second stage uses a carbon block filter, which removes chlorine,chloramines, and organic chemicals that affect taste and odor. It alsoprotects the RO membrane from chlorine damage, helping ensure clean,better-tasting water and longer system life.

3. RO Membrane

The third stage is the RO membrane, which removes up to 99% ofdissolved solids, heavy metals, and harmful contaminants. It allowsonly pure water molecules to pass through, while flushing outimpurities. This stage is key to delivering clean, high-purity water.

4. Post Carbon Filter

The fourth stage is the post carbon filter, also known as the polishingfilter. It removes any remaining odors or tastes that may linger after theRO process. This final step ensures your water is crisp, fresh, and readyto drink straight from the tap.
