Filtration of water and liquid
When it comes to filtering water and liquid, there are countless products and options, depending on which filtration problem you want to find a solution for. The problems can be many - there can be too much ocher in the water or you have to filter liquid within the brewing or pharmaceutical industry, where we have filters with an efficiency of up to 99.9999%.

- Vana AC 10" Jumbo - Active Carbon Filter€37.53
Vana AC is a high-efficiency activated carbon filter, designed to remove chlorine, chemicals, pesticides, as well as unpleasant odors and tastes from the water, ensuring improved water quality for household and industrial use. This filter utilizes activated carbon, known for its excellent ability to absorb and filter contaminants, making it an essential solution when water purity and taste are crucial.
Vana AC - Activated Carbon Filter works by binding organic compounds, chlorine, and other chemicals to the porous surface of the carbon, effectively removing impurities and leaving the water clear and fresh.
The concentration of impurities and the water flow rate directly impact the filter's lifespan. Activated carbon requires contact time with the water to be effective. The slower the flow, the better the filtration result, as the activated carbon will have more time to adsorb impurities.
It is recommended that activated carbon should not be used for more than 6 months, as bacteria growth can occur in the filter if it is in use for too long.
- Aqua-Pure™ AP110 filter - 5 µm€14.47

The filter is constructed from polypropylene, and with a filtration rating of 5 microns, it retains most particles in the water.
The filter should be replaced every 6 months to prevent bacterial growth.
- SABRE UV system - 3,8 l/min€159.36
These compact, single lamp systems are designed for smaller commercial applications, providing effective microorganism control in point-of-use applications such as private drinking water and tank-loop systems.

- Single lamp design for simple maintenance
- High quality stainless steel reactor chamber
- Reliable operation, ensuring low on-going costs
- Effective and economic bacterial / microbial protection
Effective pre-filtration is essential before a UV system to maximise the exposure of microorganisms to disinfecting UV light.
Organisms attached to suspended solids, such as dirt, sediment and debris, can be protected from UV light as they pass through the system by a phenomenon known as ‘shadowing’. We recommends using five micron pre-filtration prior to all UV system installations, to reduce the possibility of shadowing and optimise system performance.

- Vana Wound 10" - Water Filter - 120°CAs low as €8.71
This spun filter is made from high-quality cotton, providing strong and natural filtration capabilities, while its robust steel core ensures stability and durability under demanding conditions. With the ability to withstand temperatures up to 120°C, this filter is ideal for applications requiring filtration of hot liquids or in environments with high temperatures.
The filter's spun structure creates a gradual sealing process, where larger particles are trapped in the outer layers, while finer contaminants are collected deeper within the filter. This provides a high dirt-holding capacity, meaning the filter can store large amounts of dirt and particles before needing replacement, while maintaining good flow capacity. The combination of cotton and a strong steel core also ensures that the filter retains its shape and efficiency, even under pressure.

Ocher in the water – What is it?
Ocher is a naturally occurring soil type that will appear in the form of a yellow, red or brownish color. Ocher is not toxic to humans, but at the same time ocher is not the most inviting thing to have in your water, precisely because of the color it gives. At the same time, the water can have a strong smell, which is due to its lower PH value. Although ocher is not dangerous for humans, it is a different matter for some animal species. Among other things. then fish are not particularly happy with ocher in the water.
The solution to remove ocher from the water
Filter-Online receives a great many inquiries about ocher/iron in the water from customers throughout Scandinavia. We could quickly see that it was a widespread problem, especially for people with their own wells. We therefore put together a set that could be used to reduce e.g. ocher in the water, but also other unnecessary things such as organic matter, pesticides and heavy metals. On selected sets, an active carbon filter is included, which absorbs any bad smell in the water.
The kits are available in both standard and jumbo sizes with different types of filter compositions. The larger the filter housing – the greater the flow. This means that you can adapt the solution to your specific needs.
The filter housings are available in both plastic and stainless steel.
All filter housings and elements are food approved in Denmark and the rest of the EU.
3M Aqua-Pure filtration products
Filter-Online are dealers of products from 3M – a company known throughout most of the world. We have a selection of their Aqua-Pure range which includes filters for various filtration purposes. Many of our regular customers faithfully choose 3M's products and this makes us proud dealers of exactly Aqua-Pure from 3M.
Filtration of liquid – Filter housings and filter bags
At Filter-Online, we also work with products for liquid filtration. We have, among other things, bag filter housings – both in plastic and stainless steel in several different sizes, so that they suit different sizes of production. A bag filter housing is often used in connection with pre-filtration, where the coarse is caught. At the same time, the bag filter housings can handle a high flow, which only makes it more optimal as the first filter in the process.
In addition to the filter housings, Filter-Online has a large selection of filter bags made of polypropylene (PP). They are available in 4 different sizes to suit the houses and with filtration levels from 0.5 µm all the way up to 200 µm.
