My original review said these were an economical choice for clean air. And I still think that.
It turns out they may be more economical than I thought. We had an HVAC tech come to our house to track the source of a strange chirping sound when the air handler fan was running. He discovered the sound goes away with the filter removed. So he figured the filter was interfering with air flow and causing the system to work harder. Then he noticed how thick the filter material is. He was certain it was thicker than MERV 8 should be. And it was in fact thicker than the replacement MERV 8 filter I bought later at a local store. The chirping is still there, so I think I'm going to step down to MERV 5 to see if that lets more air through.
