No. The AWFS Home is not a conventional activated carbon block filter of the sort usually available on the market.

Conventional activated carbon filters are manufactured by extrusion or compression moulding. In this process, granulated or powdered activated carbon is compressed into a block using binders (e.g. synthetic resins or polymer adhesives). This construction inevitably results in a certain degree of pressure loss, a limited internal surface area and an uneven pore structure.

The AWFS Home works in a fundamentally different way:
Our carbon structure is built up on fibre-based carrier materials (e.g. rayon) using a wet-spinning process, then carbonised, activated and processed into a highly structured membrane. This process enables:
– an extremely high specific internal surface area (m²/g)
– a predominance of micropores ≤ 2 nanometres
– a homogeneous pore distribution
– maximum adsorption capacity with minimal material usage

Conventional activated carbon filters, on the other hand, rely predominantly on mesopores and macropores (10–50 nanometres and ≥ 50 nanometres respectively), which, whilst allowing fluid to pass through, exhibit a significantly lower selective adsorption capacity.

Sputtering technology – the key difference

Another technological difference lies in the sputtering technology used by Evodrop.

In this process, functional layers are precisely applied at the nanoscale in order to specifically optimise the adsorption and binding properties. This process originated in the high-tech industry and enables controlled surface modification at the atomic level.

The result:

– Targeted pollutant adsorption
– Stable adsorption structure
– No material abrasion
– No channeling
– No significant pressure loss in the system

As a result, the AWFS Home operates with high filtration efficiency whilst maintaining a stable flow rate.

Verification of filtration performance

The filtration performance of the AWFS Home has been tested and verified in independent laboratory tests conducted by SGS. The test reports document significant filtration of known pollutants under standardised conditions, including the complete removal of PFAS*.

The full test reports can be provided on request.

The AWFS Home is a household filter and is installed directly onto your home’s main cold-water supply pipe. It is important to follow a specific installation sequence. The AWFS Home must be installed after the water meter, the pressure regulator and the sediment filter (backwash filter).

No, the AWFS Home does not produce any waste water and does not require any electricity either.

For hygiene reasons, it is recommended that the filter be replaced every 6 to 12 months at the latest. However, an earlier replacement within this period may be necessary if the water flow is noticeably reduced. This is not a fault with the filter used, but an indication of an increased presence of fine particles in the unfiltered water. Due to various external factors (house size, water hardness, water consumption, pipework, etc.), we will advise you of the maintenance interval on a case-by-case basis.

Evodrop guarantees a term of 12 months, unless otherwise agreed in writing.

An AWFS Home replacement filter costs €479,-

Important information:

There are no further costs for you. No electricity, no sewage charges, no other maintenance contracts and no hidden costs.

Our ‘activated carbon’ is carbonised, activated and finally spun using a wet-spinning process on membrane-like fibres, such as rayon. As a result, we are able to achieve outstanding results in terms of specific surface area (m²/g) compared with conventional activated carbon filters. Above all, our cartridges consist predominantly of micropores with a diameter of ≤2 nanometres. Conventional activated carbon consists mainly of mesopores and macropores, which are significantly larger (10–50 nanometres and ≥50 nanometres).

In other words, the AWFS Home filters at 0.002 micrometres, whilst standard activated carbon filters filter at 0.1 micrometres.

No. With the AWFS Home, all domestic water is treated directly – there is no need to mix in any untreated water.

The bypass is set so that 100 per cent of the water flows through the system. This ensures that every tap in the house benefits equally.

The AWFS Home operates without electricity, without waste water and without additional regeneration cycles. There is no blending, as there is no need to dilute or adjust the water.

All the water is treated thoroughly and evenly, efficiently, consistently and without any bypass flows.

Our high-quality activated carbon has a surface area of up to 1,500 square metres per gram (compared to 1,000 square metres for competitors). This means that just a few grams of this highly porous material cover an area larger than a football pitch. Thanks to our special modulation, we have a larger surface area, which prevents channelling and ensures consistent filter quality. With conventional membranes, filter quality fluctuates or is inconsistent, which under extreme conditions can lead to a significant release of pollutants into the water. The advantage of our AWFS Point of Use is that it consists of 70 per cent micropores, which have a pore size of less than two nanometres (0.002 µm). This greater volume of micropores creates more surface area for adsorption. Conventional activated carbon filters have only around 10 per cent micropores. Unlike conventional activated carbon filters, the AWFS Point of Use utilises capillary action, which enables rapid and efficient filtration through adsorption. Conventional activated carbon filters would either not provide sufficient contact time or restrict the flow too much to be of any use. There are many products on the market that are prone to channel formation. This clogs the filter, significantly reducing its effectiveness. We place great emphasis on sustainability. Our filter therefore prevents channel formation, which increases the service life of our system by up to tenfold. 10–15 times higher adsorption rate 10–100 times higher mass transfer coefficient Removes 10–15 times the amount of contaminants at the same flow rate In practical testing, it quickly became apparent that we clearly have a better chlorine removal rate than conventional activated carbon. Even after 5,000 litres, we were still at over 98%, whilst conventional activated carbon filters were at 80%. Our iodine value – the most fundamental parameter for characterising activated carbon performance – is 1,800 mg/g. Competitors’ products reach a maximum of 1,200 mg/g! Fact: one gram of our material has an adsorption surface area the size of a football pitch.

It is important to understand that a supplier’s claim that a filter can remove pesticides is usually based on the pore size of the filter. This is generally a maximum of 0.1 micrometres. Pesticides or other contaminants smaller than 0.1 micrometres cannot be effectively removed from the water. Jug filters can generally only filter out particles up to a size of 2 micrometres, which means that many contaminants are not filtered out. Some companies do not explicitly point this out and do not specify the exact pore size. It is advisable to insist on appropriate evidence. Conventional activated carbon filters can only filter out particles up to a size of 0.1 micrometres. In comparison, Evodrop, in collaboration with the world’s largest testing institute, SGS, has demonstrated that contaminants down to a size of 0.002 micrometres can be effectively filtered out. Compared with conventional activated carbon filters on the market, the AWFS Point of Use filters out over 99 per cent of all pollutants from the water. With other well-known manufacturers, for example, only the cap is patented, whilst the filtration efficiency is a maximum of 60 per cent. Conventional activated carbon filters must be replaced at least every 6 months due to clogging. The AWFS Point of Use cartridge, on the other hand, remains germ-free thanks to its patented alloy and has a service life of at least one year. The AWFS Point of Use is the only filter on the market that can be connected directly to the cold water supply and guarantees the removal of over 99 per cent of all contaminants at a flow rate of 4 litres per minute. It is important to note that manganese, iron and similar substances are not heavy metals and therefore cannot be removed by the filter. The main advantage of the AWFS Point of Use is that, over time, no contaminants re-enter the water, as its structure differs fundamentally from that of activated carbon filters. In activated carbon filters, channels form over time through which contaminants can re-enter the water.
