The FILTRADOC – PRE Speed DUO 10” from Carawater is a compact combination filter (fill filter) for the pre-filtration of water when filling fresh water tanks. The dual filter system combines a washable sediment filter (1 µm) with an ultrafiltration membrane (0.02 µm), ensuring effective purification even before storage in the tank.
Due to its high flow rate, the filter is particularly suitable for mobile applications, such as in motorhomes, boats, or self-sufficient water systems. Coarse particles are reliably retained, while the ultrafiltration membrane additionally reduces microorganisms.
The FILTRADOC PRE Speed DUO operates with a two-stage filter system that combines mechanical pre-filtration and ultrafiltration.
First, the 10" sediment filter removes coarse particles such as sand, rust, or sludge from the water. Subsequently, the water is passed through an ultrafiltration membrane, whose pores are so fine that bacteria, germs, and other microorganisms are reliably retained.
This combination makes the system particularly suitable for tank filling, as the water is cleaned before entering the fresh water tank.
The combined filter removes coarse particles and microorganisms from the water. The ultrafiltration membrane can reduce up to 99.9999% of bacteria, germs, and viruses, while the sediment filter removes suspended solids from the water.
Filtration can reduce, among other things:
The FILTRADOC PRE Speed DUO is a pre-filter for particle and microorganism filtration. Targeted limescale reduction is not part of the filter system.
The FILTRADOC PRE Speed water filter is installed in the supply line to the fresh water tank, i.e. between the water source and the tank.
It serves as a filling filter, so the water is filtered before it enters the tank. Typically, it is:
This prevents sediments, suspended solids and microorganisms from entering the fresh water tank in the first place, which improves water quality throughout the system and keeps the tank clean.
You can basically install your FILTRADOC PRE Speed system yourself. However, we recommend professional installation by our installation service. This way you ensure that everything is optimally connected – and you also receive a guarantee on the installation.

The filter change for the FILTRADOC Pre Speed is scheduled after 12 months or after consuming the maximum capacity of 30,000 liters.
The sediment filter is relatively inexpensive and starts from €14.90.
The ultrafiltration membrane usually has a significantly longer lifespan (3–4 years) and usually only needs to be replaced after a significantly higher water throughput or when filter performance decreases. The cost here is €199.00. You can find all precise information on replacement filters and membranes here.
The filter change is uncomplicated and can be done in a few minutes. With our step-by-step instructions, you can easily change it yourself:
Would you prefer to leave the filter change to a professional? Our maintenance and installation service will gladly take care of this task for you.
