As Seen On
What's really flowing from your tap?
Most households assume tap water is "safe enough".
Every day, unfiltered tap water exposes your family to chlorine, heavy metals, and other dangerous contaminants. These invisible pollutants can affect your health, impact digestion, and even alter the taste of your food.
The truth is, standard water treatments cannot remove the nasties now showing up in Aussie water supplies. These fail to reduce the contaminants like microplastics, heavy metals, PFAS “forever chemicals”, that matter most...
(It's not just our opinion)
Chlorine
95% of tap water is chlorinated. Chloramine in drinking water has toxic effects on the body
WHERE DOES IT COME FROM?
A disinfectant used to neutralize and prevent bacterial growth in your tap water.

Fluoride
Fluoride can cause dental fluorosis, bone damage, and joint-related problems. Tap water contains a high level
WHERE DOES IT COME FROM?
Its added to your tap water as a public health measure to reduce tooth decay by strengthening tooth enamel and repairing early decay.

Lead
Lead is a neurotoxin that’s harmful to children. Leads to lower IQ, behavioural problems, and slow growth
Exposure to lead in drinking water can result in delayed physical or neurologic development in infants and children, and can cause high blood pressure, kidney problems, and cancer in adults.

Bacteria
Pathogens can cause immediate to long-term health issues, ranging from gastroenteritis to diarrhoea & dehydration
WHERE DOES IT COME FROM?
Bacteria can proliferate and expand in the pipes of a residence or structure if the conditions are suitable

Dirt & Rust
Dirt can add an earthy or muddy smell. Water with high iron (rust) has a distinct metallic or bitter taste
WHERE DOES IT COME FROM?
Aged water pipes deteriorate, releasing rust and other materials into the water.

Questions? Answers.
Aussie tap water is considered "safe". Why do I need this?
To ensure our tap water is 'safe' to drink, authorities add a chemical disinfectant called chlorine. Chlorine kills harmful bacteria such as E.Coli and Giardia as well as other pathogens that can harm your health.
While this disinfectant creates 'safe' drinking water, chlorine is not healthy to drink. It can damage healthy gut flora, raise the potential risk of cancer, and give water a poor taste and odour.
Additionally, water can pick up contaminants along the way from the water treatment plant to your home. Heavy metals and other impurities can leach into the water supply from old pipes and industrial & agricultural activity. Heavy metals like lead, cadmium and mercury are toxins that pose a risk to your health in the long run.
HolyH2O™ Trinity Filter System filters out 99.99% of chlorine, heavy metals, industrial chemicals and 85+ other contaminants — so you get clean, healthy, great-tasting water.
How often do the filters need replacement?
The frequency depends on water usage and the quality of your water source.
As a general guideline, the top (Stage 1 - Ceramic) & bottom (Stage 3 - Mineral Stones) generally last 8-10 months while the middle (Stage 2 - KDF) needs changing 4-6 months.
Regular checks are essential. If you notice a change in taste, it might be time for a swap. These are designed to be a breeze to replace, ensuring your water stays crisp and refreshing.

How does it taste compared to tap water?
The product is designed to recreate water from a fresh mountain stream ✨
Many of our customers have reported that water from the Trinity Filter System tastes and feels 'smoother' than their tap water.
This is likely due to addition of beneficial trace minerals in the water, which provide a “smooth” taste 🤌
You can use it for drinking, cooking, and to make better-tasting coffee and tea☕
