Electrolux Oxygen Vacuum Cleaner EL7024A HEPA Filter
filter is the HEPA filter for your vacuum and on most vacuums that use
this filter it is installed on top of the vacuum, near the back,
underneath the exhaust grill. The filter that belongs behind your vacuum
bag is the motor filter, and is not interchangeable with this HEPA
Filter. However, your vacuum requires that both filters be replaced
periodically in order to run at the highest efficiency. For more
