Binds the carbon media
Fibres bind the carbon into a more stable filtration matrix.
Learn how fibre is changing the future of filtration and how we use it to create systems that are smarter, smaller, and more efficient.
FO is our proprietary filtration platform, built on the principles of activated carbon fibre adsorption. By leveraging advanced fibre structures, FO creates a more efficient filtration matrix designed to improve contact, consistency, and performance.
Ordinary filters can channel over time. Channeling happens when water follows preferential flow paths instead of spreading evenly through the carbon. This causes some areas of the filter to be overused while other areas remain underused.
Fibres bind the carbon into a more stable filtration matrix.
The fibre network forms interconnected porous pathways, guiding water evenly through the filter.
More even flow allows more water to reach more active adsorption sites.
More usable carbon means stronger performance, less wasted media, and a smaller, more efficient filter.
FO Technology does more per gram than traditional carbon by improving water distribution throughout the matrix — creating a smaller, smarter, and faster structure that is more sustainable and efficient than standard carbon systems.
Our FO platform is the foundation behind every Purely system and has been tested for the reduction of 80+ contaminants.
A disinfectant added to almost all municipal tap water to kill germs.
A heavy metal that can leach from older pipes, solder, and brass fittings.
Plastic particles smaller than 5 mm that shed from packaging, textiles, and weathered debris.
Trace amounts of medications that slip past conventional water treatment.
A family of byproducts that form when chlorine reacts with organic matter in source water.
A longer-lasting disinfectant made by mixing chlorine with ammonia.
Cloudiness caused by suspended particles like silt, organic matter, and microbes.
A metal that can leach into water from copper plumbing, especially when water sits overnight.

FO Technology helps us do more with less. By increasing usable surface area and reducing wasted media, we can build smaller, lighter systems that use less material, reduce product waste, and lower transport-related emissions.
We believe the water industry has accepted standards that are too low, too outdated, and too slow to evolve. We created our own, built around stronger materials, smarter testing, better design, and a more complete experience for your home.
Our goal is simple: to deliver water systems that go beyond industry expectations and give you cleaner, better-balanced water with technology designed for the way people actually live.
One of the biggest gaps in filtration is the lack of digital infrastructure after installation. Too many filters are installed, forgotten, and left unchanged for years. Purely solves that with tracking, reminders, replacements, and support designed to help you maintain your system over time.
The tools to understand, maintain, and protect your home’s water long after installation.
Detailed education and local water reports help you understand your area’s water quality and the symptoms your system is designed to treat.
Detailed step-by-step guides and direct support help ensure your products are installed effortlessly.
The mobile app helps ensure you never forget to maintain or change your filter, with reminders and support when you need it.
Never think about when to change your filter again. Automated replacements ship on schedule, every time.
Most filters track time and flow. We go deeper. Our algorithm estimates your filter’s remaining capacity by analyzing your local water quality, your usage patterns, and our laboratory performance data, giving you a smarter way to know when it’s time to replace your filter.
Stay connected to your home’s water with real-time updates, regional water quality alerts, and important news affecting your area. Purely helps give you peace of mind by keeping your home informed, protected, and one step ahead.
