When is water treatment necessary?

The water quality in Germany is predominantly good to very good. However, this does not mean that the properties of the water are similar everywhere. Preventive measures in industrial facilities or in the private sector are sensible. AL-FIL-TRA stands for the promise of thoroughly filtering your water using suitable equipment and systems. One of the best-known values in this context is the lime content . But that's not all, we also remove:

The list is far from over. We regularly train ourselves in order to continuously develop and modernize our diverse range of products for you. Our service begins with advice and recording the current status. As we go on, we decide which products might be of interest to you. Our product portfolio includes water softening systems, reverse osmosis systems, iron, nitrate and other filters.

What does the Alfiltra service include?

If you are interested in new equipment with filters, we are the right people to contact. We will advise you on the technical systems and send them to you. We will be at your side during assembly or subsequent maintenance. Our experts ensure that you can rely on our products for many years to come.

When it comes to water treatment , we provide you with comprehensive advice on the options available. We provide you with real experts for installation, commissioning and carrying out the treatment.

The latter is a physical process in which the components - water and dirt particles - are separated from one another without the use of chemicals. This is done even more precisely than with a fine filter. The result is a very delicate filtering of the water, under environmentally friendly conditions in a small space.

Product: BASIC softening plant

The resin cartridges in your Basic 40 softening system generally do not need to be replaced because they regenerate themselves. The regeneration of the resin is an automated process that takes place during the cleaning cycles of the system. Here are some details:

  • Regeneration process: During regeneration, the resin is flushed with a salt solution, which dissolves and removes the accumulated calcium and magnesium ions (which are responsible for water hardness) from the resin. This “renews” the resin and can be used effectively to soften water again.

  • Regular cleaning: This regeneration is carried out regularly, depending on the amount of water used and the hardness of the water. In a 4-person household with a water hardness of 20° dH, the system will regenerate more frequently to ensure efficiency.

  • No replacement necessary: As long as the system is properly maintained and the regenerating salt is topped up regularly, the resin cartridges do not need to be replaced. However, you should regularly inspect and maintain the system to ensure its longevity and optimal performance.

  • In summary, the resin cartridges in your Basic 40 system are maintained effectively by the built-in regeneration process and therefore do not require regular replacement.

    The color always changes from the first drop. If the water hardness is greater than 0, the solution will initially turn red. You then count from the first drop until the solution turns green. If your water hardness is 0, the solution will immediately turn green.

    Regeneration takes about an hour.

    With the duplex system, only one of the two columns regenerates. This means that soft water is available to you as usual during this time.

    Installing a water softening system requires a certain level of technical understanding and craftsmanship. Installation typically involves installing a bypass valve and connecting to a sewer for regeneration cycles. Special tools and materials are required for installation. This includes pipe cutters, wrenches, Teflon tape and, if necessary, additional pipe fittings and connecting parts.

    Private customers (single-family home)

    For private customers, an on-site inspection is not necessary in most cases. Thanks to our many years of experience, we can use a few details from you to quickly assess whether and at what cost we can install the system for you, or what system you need. The best way to do this is to take a few photos with your smartphone . The photos and the travel costs saved create a cost advantage for us and therefore for you too.

    Multi-family houses and property management

    Even in apartment buildings, the house installations are usually designed in such a way that the installation of a water treatment system is possible without any problems. In order to estimate the costs, a photo of the installation on site is often sufficient. If you would still like to view the site, please contact us.

    Commercial customers (B2B)

    For commercial projects, the question of a viewing depends on the type of project. Here, it must be considered on a case-by-case basis whether a viewing makes sense. Please contact us, we will be happy to advise you.

    Germany-wide assembly service

    We offer a Germany-wide assembly service for our water treatment systems. For many systems, you can order this service at a fixed price. For larger projects or special cases, assembly is charged according to the effort involved. We would be happy to provide you with a quote for this.

    Who does your assembly?

    Our fitters are part of our own factory customer service and work from four locations. They travel throughout Germany. The advantage of this is that you save a lot of money, as our systems are not sold to third parties and our fitters are trained specifically for you and our systems. In addition, you only have Alfiltra as your contact, who will take care of all your requests or problems. Because the systems are installed every day, our fitters are familiar with all installation locations and conversions.

    Is there an on-site inspection beforehand?

    In most cases, an on-site inspection is not necessary. However, to protect both sides from any disagreements, we recommend that you take a few pictures of the installation site with your smartphone or camera. You can find out exactly what should be included in the pictures in our article:

    Pictures-What should be shown in the pictures?

    If we cannot identify anything from the pictures, we will include you in an existing tour in your area, although this can mean a waiting time of 4-8 weeks depending on where you live. Viewings are special cases, however, and hardly ever occur thanks to the trained eyes of our fitters.

    99% of all further questions can be answered by phone, email or through our Help Center .

    Alternatively, we can send you your system, which will be installed by an installer of your choice.

    The delivery times for individual products can be found on our online shop at for each item.

    We generally keep all common products in stock, so that shipping can be guaranteed within 1-2 days. We build large industrial plants to order. Therefore, the delivery time for these plants is extended by about a week. For orders with delivery to Austria, please add 1 to 2 additional working days. Orders to Switzerland require 4 to 5 additional working days due to customs clearance.

    Depending on the product type, shipping is handled by DHL Parcel or DHL Freight (forwarding company). Delivery times for parcels are usually 1 - 2 working days. For forwarding company shipping, delivery usually takes 2 - 5 working days.


    For items that require assembly (for example, water softeners in a worry-free package), the delivery time depends on our assembly planning. For this purpose, we have created a map with different zones and the corresponding waiting times for assembly for our Germany-wide assembly service. The times given are guidelines, which can be shorter or, in exceptional cases, longer.

    Since we have our own factory customer service with our own fitters, we are dependent on dividing our assembly planning into tours. This brings an enormous cost advantage, which we are happy to pass on to our customers. The disadvantage is that the waiting times may be a little longer. However, we endeavour to keep the waiting times as short as possible.
