Introducing the Defender Refillable Cartridge: Revolutionizing Protection with Sustainability!

Welcome to a New Era of Sustainable Protection

Water is essential for our daily lives, and it's important that the water we consume is safe and pure. Unfortunately, many sources of water contain impurities that can be harmful to our health, including fluoride, iron, arsenic, heavy metals like lead, cadmium, chromium, and radioactive elements such as uranium.

While technologies like Reverse Osmosis (RO), Ultrafiltration, and Nanofiltration are widely used to purify water, they have limitations in removing small molecules and certain charged contaminants. RO, for example, removes most particles larger than 0.1 nanometres, but smaller contaminants can slip through due to their molecular size or charge.

As a result, micro-contaminants like fluoride, iron, arsenic, and uranium may still remain in treated water, creating a need for an additional purification stage.

The Solution: DEFENDER

We are thrilled to introduce DEFENDER — a first-of-its-kind water purification cartridge developed with nearly 50 years of Doshion expertise in Ion Exchange Resin Technology.

DEFENDER is designed to be used after RO or other purification systems to remove micro-contaminants and ensure water purity at the highest level. Using ion exchange resin technology, DEFENDER selectively removes remaining impurities and contaminants, delivering clean, safe, and great-tasting water.

Why DEFENDER as a Post-Treatment?
DEFENDER cartridges efficiently remove smaller molecules left behind after the RO process, while also eliminating chlorine or chloramines that affect taste and odor. It's a vital component for ensuring comprehensive purification.

The cartridge is refillable, featuring a purification media pouch that can be replaced every 2–3 months — making it a long-lasting, eco-friendly, and cost-effective alternative to disposable filters.

Defender Cartridge Range

Defender Iron Removal Cartridge

Iron is a naturally occurring mineral that can affect water taste, odor, and appearance. The Defender Iron Cartridge eliminates excess iron through ion exchange technology, delivering safe and clean water free from metallic taste and stains.

Defender Arsenic Removal Cartridge

Arsenic is a toxic metal commonly found in groundwater. The Defender Arsenic Cartridge specifically targets arsenic molecules, ensuring consistent removal and protection from related health risks such as skin lesions, cancer, and cardiovascular issues.

Defender Fluoride Removal Cartridge

Designed to remove harmful levels of fluoride from water, this cartridge ensures safe drinking water without compromising beneficial minerals. It helps prevent dental and skeletal fluorosis, offering healthy and clean water for your family.

Defender Nitrate Removal Cartridge

Nitrate contamination from fertilizers and sewage can lead to serious health issues, especially for infants and pregnant women. The Defender Nitrate Cartridge efficiently removes nitrates, providing safe, clean water for all uses.

Defender Uranium Removal Cartridge

Uranium, a radioactive element, can pose major health risks if present in drinking water. The Defender Uranium Cartridge uses advanced multi-stage ion exchange to effectively remove uranium and provide safe, contaminant-free water.

Sustainability and Refillability

The Defender series uses a unique refillable design — simply replace the purification media pouch instead of the entire cartridge. This reduces plastic waste and promotes sustainability while saving long-term costs for consumers and businesses.
