quattro.

Introduction to the truu quattro, the innovative 4-in-1 pre-filter with improved filter performance, lime converter, and lead protection. Also explains the sustainable reuse concept, free filter head replacement, and stable price development.

The innovative 4-in-1 pre-filter

truu quattro is the groundbreaking innovation in pre-filtration. The pre-filter combines four highly effective filter stages in a sustainable, reusable housing. The unique wall mount with bayonet lock makes not only initial installation but also regular filter changes effortless. So you can enjoy pure, original water anytime and with ease – truu original water.

Multiple added value

Our new quattro technology offers added value in various areas. In addition to greater filter performance, a lime converter and lead protection are also used. But there are further improvements in flow rate and overall filter performance as well.

Greater filter performance

In the first filter stage, we reduced the filter pore size from 1 µm to 0.5 µm and thus achieved 100% improved sediment filter performance.

Baked activated carbon

In the field of activated carbon, we have also introduced a new technique, which has enabled us to further increase the active surface area and thus improve efficiency.

Additional lime converter

As an additional new filter stage, a lime converter is used in the quattro for the first time. This protects downstream components and contributes to long service life.

Additional protection against lead

As a further innovation, a protective filter against lead has been integrated in the quattro for the first time, because in many places pipes are still used that release lead and similar substances into the water. Thus, the new quattro contributes to worry-free use.

Green Pioneer

Good for your health. Good for the environment.

Free replacement & fit for the future

To take full advantage of the groundbreaking quattro technology, truu will give you a new quattro filter head worth 108 € at your next filter change appointment in exchange for your previous prefilter, and completely free of charge. Only the standard filter change price will be charged. In the future, you will receive the quattro by post and can change it yourself. Child's play. We promise! You send the used quattro back to us with the shipping label that will be included.

truu price development below the general consumer price index

The best comes last. Everything is getting more expensive and in some industries prices are rising dramatically. Despite the general price increase, we have managed to create significant added value with the quattro technology in terms of filter performance, integrate a lime converter, establish lead protection, and switch to an environmentally friendly overall concept in the annual filter replacement area. We consider this innovation worth changing the infrastructure at over 26,000 customers at our expense, so that our vision of a sustainable concept advances to the next level of development here as well. That's what being a Green Pioneer means. Despite all these improvements, the price for our filter replacement service remains the same and there is no price increase. Here is a quick overview to compare how the general consumer price index, electricity price index, and food price index have developed over the last 10 years.
