PFAS tests in NZ council data

The year of council results behind our water reports includes no PFAS testing at all. The newest worries are not on the routine list.

Long-Life Filters

Stage 1: Pre/Carbon Filter

Captures larger particles like sediment and rust, while activated carbon removes chlorine for cleaner, better-tasting water.

Lasts 12 months - replaced with every refill.

Stage 2: Reverse Osmosis Purification

An ultra-fine reverse osmosis filter eliminates the harmful chemicals - 99.9% of microplastics, 94%+ of PFAS, around 90% of fluoride, plus lead, chromium-6, arsenic and nitrates.

Replaced in year three - the $395 third-year refill has the membrane in it.

Nothing to remember

The unit tells you when filters are due, with a light and a buzzer. On the Filter Plan, the refill arriving is the reminder.

WHO YOU'RE BUYING FROM

A real person, not a rebrand.

I'm Mason. I moved to Queenstown a few years ago, and not long after there was a water crisis - suburbs boiling their tap water for months, people getting sick. I started looking into what's really in our water, and found an industry short on transparency: rebranded filters with fancy names, and salesmen in your kitchen before you knew the price.

So this is the opposite. Genuine Pentair hardware, the price on the page, reports built from your council's own data, and my number on every page.

Frequently Asked Questions

99.9% of microplastics in published membrane testing, PFAS by 94% or more in the Duke and NC State universities study of under-sink RO, and around 90% of fluoride. The ES60-S's independent lab report (FW250926-28-C) covers lead, arsenic, hexavalent chromium, cadmium, trihalomethanes, phenols, fluoride and nitrates. Ask us for it - we'll send it.
It is 12.5cm wide and 33cm tall, about the footprint of a cereal box on its side. There is no tank, which is the thing that normally fills the cupboard. Send us a photo if you are not sure and we will confirm it fits.
Not necessarily. Any plumber fits it in under an hour, and plenty of handy people fit it themselves in an afternoon. Nothing is built into the house, so it comes with you if you move.
The ES60 is a drinking-water unit - it filters the tap you drink and cook from, not your showers. Taking chlorine out for the whole house is the town whole-house twin's job. It fits at your mains and treats every tap in the house. Not sure which you need? Call us on 021 709 370.
The ES60 is a drinking-water unit for treated town supply. Tank and bore water needs proper treatment first. Sediment and bacteria are a whole-house job - that is what the rural twin + UV is for. Not sure what your place needs? Ring us on 021 709 370 and we'll work it out.
The unit tells you - a filter-due light on the front panel and a buzzer. Changes are one press and pull from the front, no tools. On the Filter Plan, the refill arriving is the reminder.
You can cancel anytime with one email. There's no phone call and no fee, and anything unshipped is refunded.
Of course. You're welcome to call us on 021 709 370, or start with the free water check. Either way, we'll help you work out if it's the right unit before you order.
