KOSO+ Inspired By Advanced Japanese Water Technology

KOSO+ uses advanced dual-cartridge technology that combines premium filtration inside, activated carbon, and natural minerals to help improve your everyday water.

The first cartridge helps reduce chlorine, odour, and unwanted impurities, while the second cartridge helps restore essential minerals such as Calcium, Magnesium, and Potassium.

And the best part — the process works naturally, without electricity or chemicals.


Scientific Ion Exchange Technology for Softer Bath Water

Qwik uses a dual-cartridge filtration system designed to address common problems associated with hard and chlorinated bath water.

1) The Hard Water Cartridge uses ion exchange technology to help reduce hardness-causing minerals such as Calcium (Ca²⁺) and Magnesium (Mg²⁺). These minerals can contribute to water hardness, dryness, roughness, scaling, and reduced soap effectiveness.

2) The Chlorine Cartridge uses high-grade carbon media to help reduce chlorine and other unwanted substances from the water. This helps create a gentler bathing experience for your skin and hair.

Together, these two cartridges work to help transform hard, chlorinated water into softer, cleaner and more comfortable bath water.

Cartridge life depends on water quality and daily usage. As a general guideline, for a family of 4, the KOSO+ cartridge may need to be replaced approximately every 6 months. For Qwik, a single user using it daily may also replace the cartridge approximately every 6 months.

For the best performance, we recommend following the product-specific replacement guidelines and replacing the cartridge when required.

KOSO+ is designed to continuously prepare alkaline, mineral-rich water with a simple and easy-to-follow routine.

1. Choose the Right Container

KOSO+ is approximately 11 inches tall, so use a container or matka that is larger than 11 inches and allows the KOSO+ cartridge to remain inside comfortably.

2. Keep KOSO+ Inside the Container

Once placed in the container, keep the KOSO+ cartridge immersed in the water. Remove it only when you take it out for the recommended weekly cleaning.

3. Allow the Water to Prepare

After filling the container, allow the water to remain with KOSO+ for approximately 2–3 hours.

4. Transfer the Water for Use

After 2–3 hours, take the prepared water out of the container and transfer it into bottles, jars, or other drinking-water containers for everyday use.

5. Refill & Repeat

Simply refill the same container while keeping KOSO+ inside. Continue this cycle throughout the day to maintain a regular supply of alkaline water.

Fill → Wait 2–3 Hours → Transfer → Refill → Repeat

This simple routine helps you maintain a continuous supply of KOSO+ water for everyday use.
