Common questions

How does the Kiiyo Nano-Zero filter work?

The Kiiyo Nano-Zero filter uses a multi-layer system combining activated coconut carbon and a 0.1 μm hollow-fibre membrane. As you drink, water is forced through the filter, removing 150+ contaminants including PFAS, chlorine, microplastics, heavy metals, and pesticides — delivering clean water with every sip.

What contaminants does it remove?

The Nano-Zero filter is independently tested to reduce chlorine (up to 99%), PFAS (up to 99%), fluoride (90–98%), microplastics (99%), heavy metals (95–99%), pesticides, sediments, VOCs, and pharmaceutical residues. See our full contaminant list on the product page.

How long does the filter cartridge last?

Each Kiiyo cartridge lasts approximately 3 months or 300L — whichever comes first. We recommend replacing it on schedule to maintain peak performance. Subscribe to save on replacements so you never run out.

Does it filter out good minerals too?

The Nano-Zero filter is designed to target harmful contaminants while preserving naturally occurring beneficial minerals like calcium and magnesium. You get clean water without stripping out everything good.

How fast does it filter?

Kiiyo filters as you drink — no waiting, no pumping required. The flow rate matches a natural drinking pace so you get clean water instantly, with zero effort.

Is Kiiyo covered by a warranty?

Yes. Every Kiiyo bottle comes with a 5-year warranty and a 30-day money-back guarantee. If anything is not right, our Australian-based support team will make it right. Reach us at hello@kiiyo.com.au.
