Using this filter set is easy. First, make sure your Cleanstar V2200 vacuum cleaner is turned off and unplugged. Then, open the filter compartment and carefully remove the old filters. Replace them with the new filters from this set, making sure they are properly seated. When it comes to maintenance, check the filters regularly. If they look dirty or clogged, it's time to clean or replace them. For the foam filter, you can wash it with mild soap and water and let it dry completely before putting it back. The HEPA filter may need to be replaced after a certain period of use, usually as recommended by the manufacturer. Always remember to turn off and unplug the vacuum cleaner before performing any maintenance tasks.
