Is there a cleaning and maintenance recommendation for washable electrostatic air filters. The air filter came in a box without instructions for cleaning and preventative maintenance. Any assistance would be most appreciated. The product is doing a great job as an air filter, but its showing signs of premature failure as no instructions were provided for its care and handling.

Grainger has contacted the product supplier and has been advised by them of the following. Standard maintenance for and electrostatic filter is to either vacuum the filter or rinse with water from the side opposite the air flow direction and then allow filter to dry completely. Thank you for using Grainger Ask and Answer.
