Our workshop is open from Monday to Friday. Many products that are ordered before 3:00 PM on these days can be prepared and shipped the same day.

It is possible to pick up your order yourself in Heerde. Our workshop is open from Monday to Friday from 10:00 to 16:00
As soon as your order is ready for you, we will contact you by phone or email for an appointment.

The healthy minerals remain in the water with our filtering method,

Our filters are almost all constructed from an activated carbon cylinder with a sieve perforation of 1 micron and bundle ultra membranes with a sieve perforation of 0.03 microns.

The activated carbon adsorbs all kinds of chemicals and improves the taste of the water. The 0.03 micron ultra-membranes ensure that no bacteria can pass through the filter. The water from our filter element is therefore always safe.

The natural minerals in water are always preserved with this method of filtering.

The purity of water cannot be measured with a so-called TDS meter because these types of meters also measure the healthy minerals in the water.

Unfortunately, the misunderstanding that TDS meters can be used is something that we, and other manufacturers of water filters, are regularly confronted with.

This is mainly because producers of so-called 'reverse osmosis systems' claim that this is the way to test their water. Water extracted from an RO system is completely stripped of natural minerals. In our opinion, drinking this type of water is not recommended because it can extract healthy minerals from your body.

With our filters, healthy minerals (for example lime/calcium) are not filtered out of the water. In fact, the use of activated carbon will even increase the number of particles measured with a TDS meter, compared to unfiltered water.

Due to the very small sieve perforation of 0.03 microns, the bundle of ultra membranes that are inside most filter elements do not allow bacteria to pass through.
Both ditch water and rainwater can therefore be purified with these types of elements.

However, depending on how dirty the water is, the filter will close at some point. When you have the choice of water source, the advice would be to use rainwater because it is much purer than surface water such as ditch water.
The filter will then last longer.

Although many manufacturers claim that their filter can purify a certain amount of water, this is often difficult to verify and measure.

The amount of water that can be filtered is strongly dependent on the degree of pollution of the water. Then there is also the question of what you filter and test the water on. Only bacterial reduction or also other potentially harmful substances?

The Travel-Mate has been tested for bacterial reduction; with at least 6000 liters of water, no reduced effect is visible.

With this filter we supply a sandpaper with which the ceramic can be sanded clean every now and then. If this becomes too thin (measure with the supplied jig) the filter needs to be replaced.

How long the filter will last is a good question and honestly we don't have an exact answer to this.

This is very difficult to measure. Filters with Ultra membranes such as the Siphon in principle do not allow bacteria to pass through. However, the Ultra membranes do become saturated at a certain point, so that they will then let less or no water through. This is a sign that the filter needs to be replaced.

How quickly the filter is saturated depends on the degree of pollution of the water. Water with visible contamination from mud or other materials, for example, will cause the filter to close faster than when using clear water.

In practice, the Siphon filters that we use for development work often provide a family with water every day for 2 years.

For extra Bacteria reduction, the Filter elements consisting of Ceramic or activated carbon but without Ultra membranes are treated with Nano-Silver. With the C-Ultra filters, this is not immediately necessary due to the extra high filtration of the ultra-membranes, because in principle the ultra-membranes do not allow bacteria to pass through. However, if desired, it is also possible to give the activated carbon blocks of these filter elements a Nano Silver treatment. This inhibits possible bacterial growth in the activated carbon and can therefore extend the life of the filter. These filters are then referred to as CS-Ultra.

Colloidal silver consists of pure water in which nano silver particles are dissolved. A colloid is a molecular particle (in this case silver) with a size of 1 nanometer or smaller.

Because the particles are so small, they can be dissolved in water (suspension) in a special process. In that case, these particles remain in solution and will not separate (sediment).

Because silver colloids are so small, they have a strong (positive) ionic charge. This positive charge always looks for a negative discharge.

When colloidal silver comes into contact with (pathogenic) micro-organisms, the positively charged silver colloids will bind to the negatively charged enzymes from these micro-organisms. As a result, these (aerobic) organisms can no longer produce oxygen and thus die without being able to multiply.
