Got Any Questions?

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 the lifetime guarantee work?

We offer a lifetime replacement guarantee on your Trinity Water Filter if you replace the filter cartridges every 3-6 months

(with our Subscribe & Save plan for easy, discounted refills).

This covers manufacturing defects and normal wear and tear under regular use.

If your filter stops working, we’ll replace it for free - provided you've maintained it by replacing the cartridges every 3-6 months.

(Misuse or neglect will void the guarantee)

How do I setup the system for 1st use?

Please refer to the step-by-step instructions here:

https://youtu.be/YEYtMDjLQLY

Note:
It's normal for the initial filtration to be slow as water needs to pass through the top filter. (It is crafted from densely compressed ceramic diatoms)

Once you have completed the set up & keep the tank topped up, you shouldn't have a problem.

Eventually, the flow rate will be ~ 1L/hr

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☕
