Kirbylux77 is correct. I'm just going to supplement with some knowledge from my company experience.
The Activated Charcoal filter is the MediPure cone. There is a white calendar tab inside the MediPure cone. The activated charcoal should be replaced every 6 months. The calendar on that tab is there as a reminder for you to circle which month it will be due for replacement. This cone is optional!!! It's primary function is the activated charcoal to prevent any odors escaping with use of Majestic. Primarilly it is recommended to homeowners with pets or tobacco smoke or heavy odors and gases from other sources in the home.
The regular Cellulose cone should be replaced once a month. Reason behind this is that the AntiMicrobial coating that is on that cone is only effective for one month. This cone is your primary filter for the Majestic. Always ensure that 3 tabs are visible from outside once motor is locked into place. Additionally when checking pollution container, ensure that no dust falls to the inside "Hospitable White" section of the cellulose cone. The Cellulose cone should always be "Hospitable White" on the motor side. No dust, dirt, germs or bacteria will ever penetrate that cone.
***Upon installation of new cellulose cone, the pollution container gasket should be wiped clean, this will ensure a good seal.
The Pre-Motor filter which is located underneath the ABS cone guard on motor base should be CHECKED at least bi-monthly, and cleaned or replaced as needed!! This filter is an extra protection for the motor in the event that the cone was not installed correctly or dust gets into the cone upon user removing cellulose cone. YOU WILL NOTICE A CHANGE IN PERFORMANCE OF MACHINE IF ANY DUST GETS ON THAT FILTER!!! The premotor filter is washable, vacuumable or can be banged out on side of trash can. One of these filters is included with every pack of cones.
The post motor felt filter located in your scent chamber exhaust cap up top should be flipped over or washed about every 6 months. The velcro is stapled on and is designed to be removed and restapled to the other side. These filters should last about 3 yrs, depending on condition, frequency of washing etc. They are only about 79 cents to replace.
Please don't hesitate to send me a direct email for any assistance. As a FilterQueen representative, I like to think myself as a live version of Product Manual.
Enjoy your 75th Anniversary Majestic and welcome to the FilterQueen Family!!
