The must-have accessory for filter cartridges
When changing a filter cartridge, it is sometimes difficult to align it correctly at the bottom of the jar,
then then at the top and be able to screw it back in while keeping everything well aligned.
Thanks to these rings, you'll be able to insert and fit the filter cartridge into the bottom of the jar as usual
and keep it centred at the top of the jar thanks to this accessory.
