Rainwater Filters & Pre-Filters – Clean Water for Your Cistern System
Clean rainwater is essential for the reliable operation of any rainwater harvesting system. Our filtration solutions protect your cistern, pumps, and equipment from leaves, sand, and other debris throughout the entire process – from water inlet to water extraction.
Whether you need a simple cistern filter basket, a self-cleaning rainwater filter for minimal maintenance, or the biological Biovitor system for natural water treatment, GreenLife offers the right filtration solution for every installation scenario and tank size.
Floating intake filters further improve water quality by drawing water from the clearest layer within the cistern. All systems are durable, low-maintenance, and easy to retrofit, ensuring consistently high water quality, reliable system performance, and long-term operational safety.

Built-in filter
DetailsFor filtering rainwater. The filter is installed in the dome of the tank. It has 4 inlets in DN100 (Ø110) / DN150 (Ø160). The vertically arranged outlet to the inlet stilling basin is also designed in DN100 (Ø110) / DN150 (Ø160). For maintenance, the filter basket is removed using the lifting rod.Technical DataMaterial: PolyethyleneWeight: 5 kgDiameter: 480 mmHeight: 575 mmConnections: DN100 (Ø110) / DN150 (Ø160)
Built-in tank filter
DetailsFor filtering rainwater. The filter is installed inside the cistern or tank directly between the inlet and overflow. The height difference between these connections is at least 30 mm. The filter contains a slotted screen with a mesh size of 0.8 mm, through which purified water flows vertically into the tank. During heavy rain or when the water level is very high, dirt particles are removed from the surface of the screen. Thanks to this self-cleaning effect, maintenance is less frequent than with basket filters. Suitable for surface drainage up to 160 m². A hook for lifting the filter is included.Technical Data Material: PolyethyleneWeight: 2.35 kgLength: 500 mmWidth: 195 mmHeight: 350 mm
Cistern filter basket 300
DetailsFor filtering rainwater. The filter features a filter basket with a mesh size of approx. 1 mm. Rainwater is fed in via a 300 mm long PE pipe DN100 (Ø110). The pipe can be shortened. The cistern filter basket is easy to retrofit and can be removed effortlessly for cleaning.Technical DataFilter basket material: PolyethyleneFilter basket height: 240 mmFilter basket diameter: 300 mm
Coarse dirt filter basket
DetailsFor filtering rainwater. The filter basket is suspended by its stainless steel chain in the tank or cistern below the inlet (which should have an 87° elbow). It removes coarse dirt particles (> 1.5 millimeters) from the incoming rainwater and must be emptied at regular intervals.Technical DataDiameter: 300 mmHeight: 240 mmMesh size: 1.3 mmFilter basket material: Polyethylene (no additives)

GreenLife Biovitor DN 100
Biological Filter for Rainwater Harvesting Are you looking for a low-maintenance rainwater filter that purifies your water without chemicals and achieves a high yield of top-quality rainwater? Then you’re in good hands with the GreenLife Biovitor. The Biovitor contains no wear parts, so you can rely on maintenance intervals of up to ten years. We developed the GreenLife Biovitor to eliminate the need for chemical additives and high-maintenance filters in rainwater purification. Unlike conventional designs, the Biovitor uses the same natural processes for biological self-purification as our local water bodies. This ensures consistently high-quality rainwater in your rainwater harvesting system.How our patented BIOVITOR biological rainwater filter works The Biovitor purifies your rainwater 100% chemical-free based on the natural decomposition process of organic material, such as leaf debris. It consists of two optimally sized chambers that guarantee highly efficient biological processes. Here’s how it works: Rainwater flows through the gutter grate (or other leaf guards) into the gutter and finally through the downspout into the Biovitor, which is located in the tank or cistern. The first chamber contains marble gravel, which can slightly raise the pH of the water to neutralize slightly acidic rain, if necessary. This also slightly mineralizes the rainwater.From here, the pre-treated water flows into the second chamber, which is equipped with bio-active media. Here, the remaining organic components are decomposed and broken down in the water using oxygen and natural microorganisms. Inorganic components settle at the bottom. The clear and clean water then slowly enters the rainwater tank to avoid creating turbulence. The Biovitor acts as an inlet stabilizer and achieves 100% rainwater yield, as there are no losses due to contaminated rainwater filters.Applications for the BIOVITOR Rainwater Filter Our biological rainwater filter improves the quality of your rainwater through biological processes. It is suitable for all cisterns and can be retrofitted to almost all rainwater systems. Additionally, the Biovitor is very well suited for a rainwater system with subsequent infiltration; an additional filter before infiltration is then not necessary.

Gutter grille
GreenLife's gutter guard is the perfect filter for rainwater. Whether the water is collected in cisterns or rain barrels, plant debris such as leaves and twigs can reduce water quality. It is therefore always recommended to pre-filter rainwater as thoroughly as possible, starting right at the gutter. Leaf guards filter rainwater Especially in the fall, when trees shed their leaves, it can be very frustrating when heavy rain causes leaves to enter the downspout and thus the rainwater tank. Not only does the quality of the collected water suffer from the debris, but it can also quickly clog the downspout. Cleaning often involves a lot of effort. Therefore, always use a leaf guard. Potential problems without a leaf guard Clogged downspouts Blockages in water hoses or showerheads Discoloration of the water Reduced water quality Staining of the gutter Breeding ground for pests With this simple leaf guard from GreenLife, such problems are a thing of the past. Assembly is incredibly easy, and cleaning usually requires nothing more than a hand brush. The gutter guard also provides reliable protection against birds. They can no longer nest in the gutter and must find other places to settle. Can I filter the rainwater even further? Yes, because the gutter guard is only a pre-filter. Depending on the type of your rainwater harvesting system, you can also use downspout filters, built-in filters, or tank-mounted filters. In addition to these mechanical filters, the patented Biovitoren for cisterns can also be used. These are biological filters that require very little maintenance. Installation of the gutter protection grid Installing the gutter guard is very straightforward. Each package contains segments for approximately 3.00 meters, which simply slot together. Depending on the width of the gutter, the guard can be folded. It fits any standard gutter size.https://www.youtube.com/watch?v=IVG8j1yDEMM
In-ground filter
DetailsFor filtering rainwater. The filter is installed in the ground in front of the tank. The height difference between the inlet and outlet is 130 mm. The filter contains a slotted screen with a mesh size of 0.8 mm. During heavy rain or when the water level is very high, debris is removed from the surface of the screen. Thanks to this self-cleaning effect, maintenance requirements are lower than with basket filters. Suitable for surface drainage up to 160 m². A hook for lifting the filter is included in the scope of delivery.Technical Data Material: PolyethyleneWeight: 14.0 kgDiameter (shaft): 400 mmHeight: 1,190 mm

Pre-filter for rainwater/drinking water
This pre-filter provides reliable protection against contaminants, so you can use rainwater or drinking water in your home with confidence. Install this filter system only between the rainwater pump and the point of use. With the 20 µm filter cartridges, you can enjoy clear rainwater/drinking water for 4 months. After that, simply replace the filter cartridge. The diameter of the inlet and outlet is 1 inch. Included: Filter system with removable filter chamber 1x filter cartridge, so you can get started right away Wall mount
