Yes, there are harmonic filters available for the household power grid. These filters are designed to reduce the levels of harmonic distortion in the electrical system, which can be caused by non-linear loads such as computers, televisions, and other electronic devices. Harmonic filters work by providing a path for the harmonic currents to flow, preventing them from affecting other equipment in the system. Installing harmonic filters can help improve the overall power quality and reduce the risk of equipment damage or malfunction caused by harmonic distortion. **

The cleaning of activated carbon filters is typically carried out through a process called regeneration. This involves removing the accumulated contaminants from the carbon by either thermal reactivation or chemical regeneration.

After the regeneration process, the activated carbon filters are ready to be reused for further filtration. **
