PP20 waterRO string filter 20 micron
Rating
PP20 WodaRO is a 10" string wound sediment filter for pre-filtration of cold and hot water. Made of pure polypropylene wound around a core, with a density gradient for more effective contaminant retention. It removes sand, silt, and rust, protecting the installation and devices. Filtration accuracy: 20 microns.
Description
PP20 WodaRO string filter 20 micron is a universal 10" filter cartridge for the pre-filtration of cold and hot water. It works well as a water filter in standard 10-inch inline housings, as well as in under-sink installations such as an osmotic filter, reverse osmosis filter, or other solutions supporting water treatment. Thanks to its construction made of pure polypropylene with a density gradient, it effectively captures mechanical impurities such as sand, silt, and rust, helping protect the installation and household appliances.
Effective pre-filtration for many applications
The WodaRO sediment cartridge has been designed for precise mechanical filtration. Its purpose is to retain solid contaminants present in water before it reaches further treatment stages or end devices.
It is a practical solution wherever protecting fittings, the water system, heating devices, and household appliances from deposits and particles that may cause accelerated wear of working components is important.
Cartridge construction and operating principle
The cartridge is made of pure polypropylene fiber wound around a filter core. This design is not accidental — it ensures an increase in filter density toward its core, which improves performance and makes better use of the entire filtration structure.
The density gradient means that larger contaminants are retained in the outer layer of the cartridge, while finer particles are captured deeper inside the filtration material. As a result, the filter operates more efficiently, and its service life may be longer than that of simpler solutions with a uniform structure.
Where can the WodaRO PP20 cartridge be used?
The PP20 model is intended for installation in standard 10-inch inline filters as well as in under-sink and osmotic systems.
- standard 10" inline housings
- under-sink filters
- osmotic systems
- reverse osmosis sets
- any water filtration system requiring mechanical pre-filtration
The cartridge can operate with both cold and hot water, within the temperature range specified in the technical specification.
What contaminants does it remove?
A filtration accuracy of 20 microns effectively helps reduce the presence of typical mechanical contaminants found in tap and utility water.
- sand
- silt
- rust
- other mechanical impurities of similar size
Removing this type of sediment is particularly important as the first stage of protection for subsequent cartridges and installation components. In practice, this means better operating conditions for household appliances, fittings, heaters, and water treatment systems.
Key advantages of the WodaRO string cartridge
- the cartridge's density gradient enables larger contaminant particles to be retained in the outer filter layer and smaller ones inside, which extends cartridge life
- minimal pressure drop at high flow rates
- the cartridge has PZH hygiene approvals
- made of materials approved by NSF and FDA
- operating temperature from 1°C to 52°C
- high rigidity and durability
- service life up to 6 months
Operation and replacement
The cartridge is a consumable component and should be replaced regularly to maintain effective filtration and proper water flow. The expected service life is up to 6 months or up to 14,000 liters of filtered water.
Actual durability depends on the degree of contamination in the feed water. The more mechanical sediment present in the incoming water, the sooner the cartridge may require replacement.
It is worth replacing the cartridge earlier if a noticeable drop in flow rate or a higher load of mechanical contaminants is observed. Selecting the right service interval is especially important in installations where an osmotic filter or reverse osmosis system is used, because efficient pre-filtration helps protect the subsequent treatment stages.
The service life of the cartridge depends on the degree of contamination in the feed water.

FAQ
What is the PP20 WodaRO string cartridge used for?
It is a sediment cartridge designed for water pre-filtration. Its task is to remove mechanical impurities such as sand, silt, and rust in order to protect the installation and devices operating further in the system.
Does this cartridge fit 10-inch filters?
Yes. The cartridge is 10" high and is intended for standard 10-inch inline filter housings, as well as for many under-sink filters and osmotic systems using this format.
What filtration accuracy does the PP20 WodaRO string filter 20 micron offer?
The PP20 model provides a filtration accuracy of 20 microns, effectively retaining typical mechanical contaminants present in water.
What material is the cartridge made of?
The cartridge is made of pure polypropylene fiber wound around a filter core. This construction provides suitable rigidity, durability, and effective gradient filtration.
What does the cartridge density gradient mean?
The density gradient means that the outer layer retains larger particles, while the inner layers capture finer contaminants. This solution increases filtration efficiency and helps extend cartridge life.
How often should the cartridge be replaced?
The recommended service life is up to 6 months or up to 14,000 liters. In practice, the replacement frequency depends on the quality and degree of contamination of the feed water as well as the intensity of use.
Is the cartridge suitable for cold and hot water?
Yes. The cartridge can operate with cold and hot water in the temperature range from 1°C to 52°C.
Will this cartridge work in a reverse osmosis system for the PP20 WodaRO string filter 20 micron?
Yes. It can be used as a pre-filtration stage in installations such as a reverse osmosis system, reverse osmosis unit, or reverse osmosis filter, where it helps reduce the inflow of mechanical contaminants to subsequent system components.
Does this model cause a large pressure drop?
No. One of its advantages is minimal pressure drop at high flow rates. The pressure drop parameter is within the range of 0.2 - 0.4 bar.
Does the product have the appropriate certifications?
Yes. The cartridge has a hygienic certificate and PZH hygiene approvals. It is also made of materials approved by NSF and FDA.
