Water filters for motorhomes, campervans and boats

Mobil (filling from outside) is suitable for well-maintained, clean systems. Travel (permanent installation inside) is ideal for large tanks and self-sufficient travel with a diaphragm pressure pump. The Pro Camper Set combines both – Active pre-filter outside and Nano germ barrier inside.

For water you can drink cold without any concerns, combine Active + Nano; for coffee, tea and cooking, the Active is sufficient.

Yes. Thanks to the modular design of the housings and connections, sets can be converted at any time – a filling set (Mobil) can also be installed inside, and vice versa.

No. The Nano germ barrier filters out bacteria such as E. coli, legionella or faecal germs purely mechanically. You can do without silver ions and other preservatives.

Yes. Before drinking the water cold and starting filtration, the tank should be thoroughly cleaned and disinfected – for example with an active-oxygen-based cleaner. This increases safety and extends the service life of the filters.

Yes. The cartridges stay installed during the trip. After filling the tank, briefly open the lid, drain the stagnant water, close it again and store it in a dry place.

Yes. After a longer period of non-use, remove the cartridges, let them air-dry and store them in a cool, dry place. Replace after 4 (Active) or 6 months (Nano) of use – breaks during which the cartridges are stored dry don't count. Do not store in rice, in the fridge or in a sealed bag.

No – only the time in use counts. The 4 months (Active) or 6 months (Nano) are operating time, not an expiry date. If you take the cartridge out during a break between trips and let it dry completely, the clock stops for that period.

Example: 3 weeks of summer holiday, then stored dry – next season you carry on using the same cartridge until a total of approx. 4 months of use or around 3,000 litres is reached (Nano: 6 months or around 5,000 litres).

Thorough drying is important: The Active cartridge needs 2–3 days in an airy, shady place until all residual moisture is gone. Only dry the Nano cartridge in the open air. Then store the cartridges in a cool, dry place – not in the fridge, not in rice and not in airtight packaging. If the flow rate drops noticeably before then, the cartridge needs replacing sooner.

Correct: cool, dry and well ventilated. Wrong: sealed plastic bag, container with rice or storage in the fridge.

In general household waste – they are incinerated because pollutants have accumulated inside them.

Yes, every cartridge affects pressure and flow rate. For installation inside the vehicle, a diaphragm pressure pump is recommended. Filling the tank takes a little longer – with all filter stages (Protect + Active + Nano), around 10 minutes for 120 litres.

For permanent installation: Active min. 2 bar, Nano min. 1.5 bar, Fusion min. 2.5 bar. More pressure is no problem: there is no upper limit, and higher pressure merely increases the flow rate.

A clogged cartridge is normal wear and tear, not grounds for a complaint. Check each stage individually to find the affected one: turn the Protect around and flush it clear, usually replace the Active, and flush the Nano clear with pressure against the direction of flow (in an emergency only). A pre-filter (Protect) helps prevent this.

No, the installation direction has no influence on the filter performance.

The Nano cartridge is certified according to ASTM F838-15A and can also be used in public facilities in the event of acute legionella contamination.

Both aim to make water germ-free. The Nano hollow-fibre membrane retains bacteria purely mechanically – without electricity, regardless of flow rate and turbidity, and at a lower purchase price. It is a wearing part and must be replaced, whereas a UV system can scale up or become contaminated with germs.

Active and Active Plus+: maximum 23 °C. Nano: 5–65 °C.

Pollutants and bacteria never even reach the tank, no powerful pump is needed, the filter can also be used to fill canisters – and no installation is required. With consistent use, germ contamination is very unlikely and no biofilm forms.

Before drinking the water cold, a thorough system cleaning is necessary, and consistent hygiene is required to prevent germs from entering the system.

No. While travelling, the cartridges stay installed; only the stagnant water is drained. Remove and dry them only after the holiday.

The internally installed Nano germ barrier provides protection close to the point of use, the Active filter also reduces pollutants from plastic tanks, filling the tank is not slowed down and no pressurised water point is needed.

A pressure pump with min. 1.5–2.5 bar is needed (depending on the variant), the filter has to be installed in the water line, and unfiltered water gets into the tank – this can be solved with a switch-over device.

A diaphragm pressure pump with the following minimum pressure is recommended: Travel Active min. 2 bar, Travel Nano min. 1.5 bar, Travel Fusion min. 2.5 bar – this way, the full cartridge capacity is used. More pressure is no problem: there is no upper limit, and higher pressure merely increases the flow rate.

The safest place is directly under the sink at the point of use. Alternatively, directly after the pump in the cold water line to protect the entire pipe system.

The Alb Filter can often be integrated using two 1/2-inch adapters or connected to the flexible 10 mm hoses via the Travel connection kit. If needed, send us a photo of the system – we'll be happy to advise you.

It combines external filling (Active pre-filter) with an internally installed Nano germ barrier: pollutants are reduced before they reach the tank, the water enters the tank very clean and is protected against germs at the point of use.

A pressure pump with min. 1.5 bar (higher is no problem) is recommended, and the internal filter has to be integrated into the water line.
