Subscribe & Save | HolyH₂O — Automatic Refills & Lifetime Guarantee

Subscribe & Save

Automatic Refills. Guaranteed for Life.

The Subscribe & Save program keeps your Trinity Water Filter and Shower Mate performing as they should — with automatic cartridge refills at a discount, and a Lifetime Guarantee that's only possible because the cartridges are actually being replaced.

How It Works

Set your preferred delivery frequency at checkout or from your account. Your cartridges ship automatically, you save on every order, and your Lifetime Guarantee stays active.

  1. 1
    Choose your frequency

    Select every 3 or 6 months for Trinity cartridges and/or Shower Mate refills. You can set different frequencies for each product.

  2. 2
    Get a reminder 3 days before each shipment

    We'll email you 3 days before your next order processes so you have time to make changes, skip a shipment, or update your address.

  3. 3
    Your order ships automatically

    Your stored payment method is charged and your refills are dispatched from Sydney. You'll receive a shipping confirmation with tracking once it's on the way.

  4. 4
    Replace your cartridge — keep your Lifetime Guarantee active

    Replacing your cartridge on schedule is what activates and maintains the Lifetime Guarantee. If you ever need a replacement unit, it's on us.

Why we recommend 3 months: Both the Trinity KDF cartridge and the Shower Mate filter perform best when replaced every 3–4 months in typical Australian households. For higher-usage homes or poorer source water quality, 3-monthly replacement maintains peak filtration performance.

The Lifetime Guarantee

Both the Trinity Water Filter and Shower Mate come with a Lifetime Replacement Guarantee — active for as long as you maintain a Subscribe & Save plan and replace your cartridges on schedule.

Trinity Water Filter Lifetime Replacement — Free

If your Trinity fails due to a manufacturing defect or normal wear under regular use, and your KDF cartridge has been replaced every 3–6 months, we'll replace the unit at no charge.

Shower Mate Lifetime Replacement — Free

If your Shower Mate fails due to a manufacturing defect or normal wear under regular use, and the filter has been replaced every 3–6 months, we'll replace it at no charge.

What voids the guarantee: Misuse, accidental damage, or failure to replace cartridges regularly. The guarantee is built on the premise that a well-maintained filter shouldn't fail — if it does, that's on us. If cartridges aren't being replaced, we can't verify the filter was maintained, and the guarantee won't apply.
Why we offer this: A lifetime guarantee only makes sense if the products are built to last. We offer it because we're confident they are — and because keeping customers long-term matters more to us than the cost of an occasional replacement.
