Seven Stages of Water Purification

The Aqua Care 400 GPD Under Sink RO System uses seven filtration stages to treat water.

Stage 1: PP Sediment Filter

Helps remove suspended particles such as sand, rust and dirt before water reaches the subsequent filtration components.

Stage 2: GAC Carbon Filter

Uses granular activated carbon to help reduce chlorine, odour and certain organic compounds.

Stage 3: CTO Carbon Block Filter

Provides additional carbon filtration to help improve taste and protect the RO membrane.

Stage 4: 400 GPD RO Membrane

The reverse osmosis membrane helps reduce dissolved salts, total dissolved solids and selected contaminants.

Stage 5: Post Carbon Filter

Provides final carbon filtration to help improve the taste and odour of the purified water.

Stage 6: Post Mineral Filter

Provides a mineral-conditioning stage as part of the system’s water treatment process.

Stage 7: Alkaline Filter

Provides additional water conditioning intended to adjust the pH according to the filter design and incoming water conditions.

Why Choose an Under Sink RO Water Purifier?

An under-sink water purifier provides a dedicated drinking water filtration system while keeping the main unit out of sight. It can be a practical choice for kitchens where space, convenience and a higher rated production capacity are important.

Before choosing an RO system, consider your daily water consumption, incoming water quality, available water pressure and filter replacement requirements. Regular maintenance is essential for consistent performance.
