This method is commonly used in air purifiers and can be effective in reducing dust in the air. **

No, HEPA filters from vacuum cleaners should not be washed underwater. Washing the filter underwater can damage the delicate fibers of the filter and reduce its effectiveness in capturing small particles. Instead, it is recommended to gently tap the filter to remove any loose debris and then use a vacuum cleaner with a brush attachment to remove any remaining dirt. If the filter is very dirty and needs to be cleaned, it is best to follow the manufacturer's instructions for proper cleaning and maintenance. **
