Massive reduction in air flow in furnance with air filters
First, does the 3m filter meet the furnace manufacturer specs?  Second, do a simple test. Observe the air flow with the 3M filter in, change it out to an old filter or no filter at all. Is there a big difference in air flow?  Are any of the returns covered with a carpet or other obstruction?  If the no filter test greatly improves flow and there are no obstructions, you may have the wrong filter. If if doesn't improve with no filter, then call a tech and start looking at the furnace blower.
