Nature Works® Glass Filter Media is a filter media made from virgin granulated glass, designed to replace the silica sand in any standard filter available on the market and intended for both domestic (swimming pool) and industrial water filtration.
It is the only water treatment filter media that provides maximum performance; reusability; energy, water and chemical savings; certified purity and total safety during installation. It is an ecological, recycled and recyclable product that reduces the environmental impact of water treatment.
Thanks to its advanced Anti-Compaction Technology, its smooth edges and its polyhedral morphology, it prevents the appearance of biofilm and chloramines. It does not require flocculants and reduces pressure loss to a minimum. The quality of Nature Works® Glass Filter Media is guaranteed by international product, production, water treatment and traceability certifications.
The aseptic properties and the Anti-Compaction Technology of Nature Works avoid the formation of biofilm. This important characteristic is accredited by accreditation laboratories.
Biofilm is responsable for chloramines, clogging and channeling in the filter mass. With the use of Nature Works you will find a difference straight away.
The crystal silica is a compound mineral that can be found in rocks and sand and may be found in filtration sand. A long term exposure to this compound could lead to various lung problems.
Free silica is considered a cancerous substance by IARC (International Agency for Cancer Research).
Nature Works® avoids this hazard as it has no Free Silica in its composition. Certified by Bureau Veritas Certification number BV ES026775-A-CPI.
The efficiency of Nature Works is based on the elimination of the most common particles you can find in a swimming pool that make the water go misty. This simultaneously maximizes savings and efficiency.
The utility of a filter media is determined by a compromise between micron rate and clogging capacity.
The Anti-compaction Technology has been designed to keep the micro channels that form in the filtering mass open. When they are kept unblocked, the pressure in the filter stays at its minimum level and the clogging capacity stays at its maximum level, resulting in the following savings:
▼ Up to 60% of the pump consumption*
▼ Up to 10% of the heating consumption*
At the same time as we save energy, due to keeping the micro channels open, we also manage to save water as we reduce backwashing. This means:
▼ Up to 35% in water consumption when backwashing*
Most of the chemicals used for the maintenance of the water are aimed at eliminating biofilm. The certified absence of this gives us:
▼ Up to 30% saving in the cost of chemical products*
* Results compared to silica sand
Most of the filter medias available on the market come to the end of their useful life prematurely due to the effect of compaction (caking), a process where the segregation of fine and thick grains block the microchannels of the filtering mass.
In order to avoid this result, Nature Works® has developed the Anti- Compaction Technology®, a precise selection of the calibre of the grain, designed to extend the useful life of the media indefinitely.
Nature Works only needs a single layer, with only one grain size, to offer a maximum performance, unlike other filter media that require multiple layers of different grains to be effective.
This means Nature Works can be used time and time again. In the case of having to be taken out for any reason, such as damage to the filter or changing the water traps, you just take it out and reuse it in a safe and easy way.
Safety is a basic quality when it comes to products used for water treatment for human use. For this reason at Nature Works we subject our glass to an advanced micro grinding to eliminate sharp and cutting edges.
With this process we obtain a glass that is harmless and completely safe to handle.
The filter media is in constant contact with the water once it is installed, therefore it is fundamental that it is free of contaminants that could end up in the water.
Nature Works is a completely sterile product made from clean virgin flat glass, with a purity level of at least 99,999%, certified by Bureau Veritas, which corresponds to the lowest possible detection limit.
Nature Works is made from recycled virgin glass, in other words, new glass that has never been transformed.
This is the only way to guarantee the absence of bacteria or any other microscopic contaminants.
Due to its advantages and technical characteristics, Nature Works® can be found today in more than 100,000 installations all over the world. Its main uses are found in:
We help you solve some of the most common questions.
Nature Works® takes up more space than silica sand because of its particle density difference and its Anti-Compaction Technology, therefore you will need 20% less than the amount recommended by the manufacturer on the filter instructions.
The combination of layers with different sized grains inside the filter is needed when the filter media has not Anti-Compaction Technology, in order to delay clogging and be able to do a correct backwashing.
Thanks to its High-Calibrated filter media grain curve, Nature Works® does not need different layers in any kind of filter. This also ensures an indefinite shelf life.
Nature Works® has been designed and produced specifically for use in water filters. To ensure maximum purity only virgin glass is used, it’s the only glass with controlled origin and guaranteed not to have been in touch with bacteria or any other contaminating materials.
Unlike other glass filter media, it does not come from urban glass banks and therefore is the only one suitable for water filtration for human consumption.
Thanks to its advantages and technical characteristics Nature Works® is used in over 100.000 installations all over the world.
Used mainly in:
All our models are able to filter 1 μm. with crescent effectiveness.
The model with highest effectiveness is not recommended for swimming pool because due to its minimum clogging capacity, it obligates to make continue backwashing and it is thrown out to the sewage in the backwashing process.
The recommended use for this model is, generally, applications without suspended matter > 10 μm.
A Certificate has to be issued by a Certification Company, which does not issue filtration micron rate certificates. We count on the tests from the french IFTS laboratories for filtration.
Silica sand loses its filtration capacity in a short period of time due to the growth of biofilm (bacterial colonies) between its grains, which creates preferential channels and clogging.
The absence of biofilm plus Anti-Compaction Technology makes Nature Works one of the most efficient filter medias on the market.

Yes, all standardized filters allow the use of Nature Works®. If your filter does not have the worldwide harmonized nozzle opening size [0,35 +- 0,015 mm], we recommend you change the nozzles for standard ones
Glass obtains its colour when its being manufactured due to different chemicals, metals and oxides being added to achieve each colour. As it is encapsulated at a molecular level, this does not change any of the glass ́s properties, nor does it affect the filtering process.
However, as the glass used for the coloured filter media comes from glass banks, not directly from the manufacturer, it may have all sorts of bacteria and contaminants that can end up in the water, which makes it risky to use in water filters for human consumption.
By definition, filtration is a mechanical process where no other forces intervene, unwanted particles are retained in a filter due to the interaction of the water flow and the filter media.
Due to its insulant nature, glass does not allow the free circulation of electrons, and therefore it is not possible to “charge” or “activate”. Some other manufacturers claim that their glass is “activated” yet this feature has not been backed up by any studies or demonstration.
