How to Make a Replacement Post Motor HEPA Filter for Prolux Upright Vacuums

Owning any vacuum requires maintenance. At GreatVacs we understand the importance of understanding how to properly maintain your vacuum. In this video, we explain how to make your own replacement post-motor HEPA filter using a Kirby bag.

Important Safety Tips

  • Always make sure your machine is unplugged and the power button is turned off, before servicing your vacuum.
  • Always make sure your hands are dry and free from moisture before servicing your machine.
  • Be sure to wear gloves when servicing your machine to prevent any cuts or scrapes.
  • If you are uncomfortable working on your vacuum, please don’t hesitate to contact us at and we can help you through the process or you can send it into us to fix it for you. 



  • Your existing post-motor filter
  • A HEPA bag
  • Scissors
  • Marker




Take your existing post-motor filter and lay it on the HEPA bag.


Using your marker, trace the filter.


Then cut along the line you made.


Now you have a new filter that’s the same size as the old one! The great thing about the HEPA bag is that you can make about 3-4 replacement filters!
