Contaminants the Defender Protects Your Home Against

Chlorine

A disinfectant added to almost all municipal tap water to kill germs.

Lead

A heavy metal that can leach from older pipes, solder, and brass fittings.

Microplastics

Plastic particles smaller than 5 mm that shed from packaging, textiles, and weathered debris.

Pharmaceuticals

Trace amounts of medications that slip past conventional water treatment.

Chloroform

A disinfection byproduct that forms when chlorine reacts with organic matter in water.

Haloacetic Acids

A group of disinfection byproducts linked to long-term health risks with ongoing exposure.

Copper

A metal that can leach into water from copper plumbing, especially when water sits overnight.

Rust & Sediment

Fine particles of corroded iron and grit that flake off aging pipes and water mains.

Better Water

Not all filters are created equal.

Traditional carbon filters rely on synthetic polymer binders to hold carbon together, reducing the amount of active filtration media inside the filter. Purely uses fibers to form the filtration structure, creating significantly greater surface area for more efficient contaminant adsorption and longer-lasting performance.

Developed in Japan. The Science Behind Fibre Filtration.

Developed in Japan during the 1970s, Fibre Optimization Technology replaces traditional carbon structures with activated carbon fibres. The result is greater surface area, faster adsorption, and longer-lasting filtration performance.

0+

Adsorbs contaminants up to 100× faster than traditional granular carbon media

0m²/g+

A single gram of fibre holds an internal surface area roughly equal to half a football field

<1/2

Less than half the physical size of a standard carbon block — with greater capacity

The Science That Sets Us Apart

At the core of every Purely system is activated carbon fiber, an advanced filtration material proven to be more efficient and sustainable than traditional carbon filtration.

The water in your home affects far more than you may realize.

From the first glass in the morning to the steam in your evening shower, one water line touches every part of your family’s day.

The P1+ Whole-Home Defender is the only system designed to protect every one of these touchpoints, filtering every drop of water before it reaches a single tap in your home.

Why Whole Home Filtration Is Superior.

A whole-home system protects every drop of water your family uses, every day, for years. Compared to what homeowners spend on furniture, subscriptions, and other everyday expenses, it is remarkable how much value a whole-home system delivers for its cost.

Filtered water from every tap in the house — kitchen, bathroom, basement bar — not just the one under the filter.

FAQs

The P1+ Defender is installed at your home’s main water entry point, so it treats the water before it travels through the rest of your plumbing system. This allows it to help protect the water flowing to your showers, faucets, and appliances throughout the home.
