Watch those cheap-o blue spun fiberglass filters. They allow a lot of dirt to pass through and deposit on the indoor coil.

Take care.

True enough, but I'm trying to keep our HVAC guys in business with an annual maint job.

whistle not a bad idea as a backup to regular filter changes for those "damn i got busy and forgot all about it times"

by the time the filter gets dirty enough to blow the whistle it should have been replaced weeks ago.

I have always used the monthly filters. Hubby bought some better filters and today when I changed them the return in the hallway started to whistle, it never has before. So should I go buy the cheap filters again? Will these hurt the system if left in?

What brand filter is the new filter.

Those are normally not an excessively restrictive air filter. Your returns are probably a little small.
Might want to go back to the cheaper filters or you get your return increased.
