Pleated polyester cartridges offer a simple, practical means of filtration.
Ease of maintenance, high dirt holding capacities, high flow rates and a low pressure drop provide the lowest cost per litre filtered.
When the flow rate significantly slows, the cartridge may simply need cleaning and this can be done by placing the cartridge under a running tap/ gentle hose.
Reusability of these cartridges means that the pleated polyester cartridge is an extremely cost effective means of filtration in comparison to the standard disposable type cartridges. They can be cleaned several times before a new replacement is required. A new cartridge may be needed when cleaning is no longer effective. Life of the cartridge will depend on your water quality and cartridge micron rating (e.g. 5 micron cartridges may only be cleaned once or twice).
