How often do you need to change the filter and is it reusable?
By Customer Service on July 16, 2012
We have received your recent product inquiry regarding replacement filter cartridges for the 3D-HOB Filter. On average the filter cartridge should be replace every 30 days. The material is rather durable and can be rinsed and reused but the units are filled with activated carbon which will last for approximately 30 days under normal working conditions.
If you have any further questions please do not hesitate to ask.
