Using your Volta Lite U1660 Hepa and Micromesh Filter Set is easy. First, make sure your appliance is turned off. Then, locate the filter compartment and carefully remove the old filters. Install the new Hepa exhaust filter and micromesh motor filter in their respective places. Ensure they fit snugly. When it comes to maintenance, it's a good idea to check the filters regularly. If they look dirty or clogged, it's time to replace them. Keep in mind that the color of the filter you receive might be black or orange, but both work equally well. Also, always handle the filters gently to avoid any damage. This way, your appliance will keep running smoothly and efficiently.
