I have a spacegard 2000 in my home. A while ago when i had a heater guy do heater maint. he did not have the right filter so he put in a skinny one. I mistakenly threw out that cage thing that went around the correct filter. I see the upgrade kit but am unsure if it will work as mine may be older.
In order to determine if your air cleaner will work with the new upgrade you will need to check the air cleaner for a guide rail on the top and bottom of the air cleaner box. If you do not have this rail, you will simply notice that there is nothing on the top and bottom of the air cleaner but flat sheet metal. If there is not a rail in your unit, you will not be able to use this kit because the new bracket needs it to stay in place.
