Using this filter set is easy. First, turn off your Volta Mega or Ultima Gen3 vacuum cleaner and unplug it from the power source. Then, open the filter compartment and carefully remove the old filters. Place the new micromesh motor filter and Hepa exhaust filter in their respective positions, making sure they fit snugly. Close the compartment and you're ready to use your vacuum cleaner again. When it comes to maintenance, it's a good idea to check the filters regularly, about once a month. If the filters look dirty or clogged, you can replace them. Always store the filters in a dry place to keep them in good condition. Remember to follow the manufacturer's instructions for your specific vacuum cleaner model. And if you have any questions, feel free to reach out to our customer service team.
