How Chlorine Impacts Your Hair And Skin.
.svg)
Strips Natural Moisture
Washes away protective oils, leaving your hair and skin feeling dry, tight and irritated.
Weakens Hair
Breaks down essential proteins (amino acids), leading to increased breakage and fragility.
Aggravates Skin
Triggers skin sensitivies, which can result in eczema, persistent itchiness, and rashes.
Reduces Shine
Dissolves the natural lipis that give hair its healthy sheen, causing dullness and split ends.
Fades Your Colour
Reacts with melanin, causing your natural salon-treated hair colour to fade faster.
Accelerates Aging
Heavy metals can trigger free radicals, which break down collagen and reduce skin elasticity.
.avif)
Coffee
Better water means better flavour. Smoother, richer, and more balanced taste.
Fruits & Vegetables
Rinse away contaminants and preserve freshness with cleaner water.
Pets
Give your pets the same quality water your drink, pure safe, and healthy.
.avif)
Showering
With chlorine and impurities removed, your shower leaves you hydrated, not stripped.
.avif)
Clothing
Chlorine fades colors. By effectively removing it, our filter helps protect your fabrics.
Drinking
Enjoy clean, great-tasting water, right from your tap. Our filter is designed to effectively reduce over 100 common impurities.
Why Fiber Technology?
Our filtration technology delivers stronger performance, better pressure, and longer life than traditional filters. Here’s why:
Beyond Granules
Most filters rely on loose granules. Over time, water carves channels through them, causing uneven filtration and a shorter lifespan.
A Smarter Structure
Our filter uses a solid, fibrous media with a high-density surface area and thousands of micropores. This structure guides water evenly through the filter for smoother, consistent, and more effective purification.
.avif)
Compact Footprint
Our advanced fiber technology is incredibly efficient, enabling a much more compact filter. The P1+ fits easily into tight spaces, making it ideal for apartments and condos without compromising performance.
.avif)
Full Flow, Instantly
The fiber membrane is designed to be highly permeable. This allows water to flow through quickly, providing consistent, high-flow water and strong, uninterrupted pressure to every faucet in your home.
.avif)
A More Sustainable Choice
The immense surface area of our fiber technology means it can do more with less. This high-efficiency design results in less material waste, making it a smarter, more sustainable choice for your home.
Which P1+ System is Right For You?
Find your household size for the perfect system. We recommend choosing based on the number of people living in your household for the most accurate filter lifespan.
