Please Note: When purchasing, make sure to add each filter to your cart one by one — they are not bundled automatically.
If you’re simply replacing your filters, you don't need to purchase a whole new PreFilter housing.
TOWN WATER
Recommended set:
3. H2 Booster (For Triple Systems)
- H2 Booster (Add-On for Twin Systems)
TANK WATER
Recommended set:
3. H2 Booster (For Triple Systems)
- H2 Booster (Add-On for Twin Systems)
BORE/RIVER WATER
Recommended set:
3. H2 Booster Filter (For Triple Systems)
- H2 Booster (Add-On for Twin Systems)
Important: If you're using a water ionizer with bore water, a water softener is essential.
Without it, mineral scale can coat your ionizer's plates, severely reducing its ability to function.

TRAVEL/CARAVAN/RV WATER
This set can be customised based on your setup, but we recommend at least the following:
If you’re using an under-sink twin or triple system (which we highly recommend), include:
- Carbon Ultimate Filter
- Ultrafilter 0.01
- Fluoride Filter or H2 Booster (depending on your needs).
Tip: We also recommend including a Water Softener, especially if you’re travelling through areas with hard or mineral-heavy water, as it helps protect your system and improve overall water quality.

H2 INLINE BOOSTER KITS
Our H2 Inline Booster Kits are designed for homes that already use a Twin Above-Sink or Twin Below-Sink filtration setup and want to enhance their water with added molecular hydrogen.
Each kit includes a mineral-rich canister that supports the electrolysis process in water ionizers and boosts hydrogen production — especially helpful if your source water is low in minerals.
You have two kit options, depending on your setup:
The only difference between the two is the fittings — the booster canister and its function are exactly the same. Just choose the one that matches your system for seamless installation.
💡 Note: After installation, some users notice temporary gas buildup, which may cause the water to spurt or jerk when turning on the ionizer. This will stabilise after a few uses.
