Should I use filters on my air vents?

Consumer blog question:

I am confused. I have three Aprilaire air cleaners in my home. Apprx. 6000 sq. ft home. I have 7 return air panels in my ceilings. Are you saying I should not put in my 14 x 30 air filters in my returns. I would appreciate your expertise on this for my builders says that the extra filtering cannot hurt. I am of the opinion that I am blocking return air with more filtering.

Aprilaires' response:

Thank you for contacting us.  When using Aprilaire Whole House Air Cleaners, we do not recommend using any other type of filter in your system(s).  By using additional filters, you are not allowing the Aprilaire to work to it's capacity.  In addition to that, you would still have to replace the "drop-in" filters on a monthly basis.  If the monthly filters are not changed when needed, the clogged or full filter can starve the equipment of the needed air to operate.  The only filter we recommend using is the Aprilaire Whole House Air Cleaner.  Please contact our Customer Service Department if we may be of further assistance.
