Prefer to sort your own cartridges? Fine by us - the machine is yours either way. The plan is there when you'd rather not think about it.

More Sipping, Less Restocking

One price: $245 a refill, billed only when a refill ships. The schedule you pick decides how often a refill comes. We email before each one ships, and you can skip it, move it, or cancel the lot - no phone call, no fee, anything unshipped refunded.

Stretch

$245/refill

The longest schedule, the fewest refills

Same refill, stretched further, so it costs the least per year. The carbon will be fading before each swap, and you may taste chlorine near the end. Some households are fine with that, and if yours is, we will say so.

Always fresh

$245/refill

Changed early, every time

For households that want the filters changed early, before there's any chance of noticing them fade. The Right on time schedule is already safe. This one's about freshness.

Three Steps, Then It's Sorted

Check your water

Tell us your address, household size, and what system you have. If you're not sure what's installed, a photo or your install invoice is plenty.

We work out when your filters are due

A carbon cartridge only holds so much. How fast yours gets used up depends on your household's water use and your supply's chlorine. We do that maths for you.

Cartridges arrive when they're due

There's nothing to remember - the refill turning up is your reminder. You're billed only when a refill ships, and you can change or cancel any time.

Frequently Asked Questions

From your water and your household. Your supplier publishes what's in your water, and you tell us how many people are in the house. We work out how long a cartridge will actually last at your place. It's all laid out in your report.
No. Cartridge changes are DIY-friendly with the included spanner, and each parcel comes with plain instructions. If you get stuck, call us on 021 709 370 and we'll talk you through it.
If the cartridges we send don't fit, that's our mistake, not yours. Send a photo, keep the wrong ones, and the right ones go in the post that day.
You can cancel anytime with one email - no phone call, no fee, and anything unshipped is refunded. If it's the cost, you can drop to the lighter plan instead and keep the filters coming.
Yes. Most standard whole-house systems take the same cartridge formats we stock. Send us a photo of your setup, or forward your install invoice, and we'll confirm whether we can supply it.
