How chlorine impacts your hair and skin.

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.

Performance you can see. Purity you can taste.

Engineered at the microscopic level to filter deeper, flow faster, and last longer.

Consistent filtration. Our next-generation pore structure filter technology ensures dependable performance from the first drop to the last.

Expanded surface area. Purely filters use ACF media with up to 3× greater accessible surface area than conventional granular carbon, enabling faster adsorption.

Superior Contaminant Capture. Backed by advanced activated carbon fibre, our filters target chlorine, VOCs, pesticides, and heavy metals with higher efficiency than standard filters.

Compact & Long-Lasting. We’re half the size, yet double the capacity. We deliver more purified water with fewer filter replacements. We’re not just better, we’re easier.
