Water filters are generally made of plastics and activated carbon. So this means it is a composite material.
This should be placed in the general waste bin.
Water filters cannot be recycled as part of your recycling collection scheme nor at Civic Amenity Sites. However, if you use a BRITA branded water filter you can recycle the used filters at most Argos and Homebase stores where boxes are provided for the collection of used cartridges.
Brits filters can be sent for recycling, free of charge to: Freepost License FAU V92, Bluestone Sales & Distribution, 26 Oaktree Business Park, Trim, Co. Meath, C15 HK40
You can also take them to the Civic Amenity sites in Trim, Navan and Kells.
Please note that they can only accept BRITA brand cartridges for recycling. When sending back cartridges please ensure that they are dry. https://bluestone.ie/recyclebrita/
