3M filters are notorious for restricting airflow. I hate to say it but asking for help in selecting the appropriate filter for you is the same as asking what equipment you should purchase. Every pro and every wannabe will have a different opinion. I'd recommend a good internet search for a product that meets or exceeds the MIRV rating you're seeking while keeping the airflow restriction low. Oncel you've settled on the filter or filters you'd like, then you can begin to shop for what is readily available in your area. I'd steer clear of the big boxes however. I've yet to see them stock anything that approaches what a true professional would recommend.

If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!
