I bought Merv 16 approx 1 month ago for my whole house furnace and my allergies and asthma has really lessened. I am not sneezing, my asthma attacks and my breathing is 99.9% better.

The product works well. It was a great price. The package arrived dented and the corner of one filter was also dented but I straightened it out and used it anyway. Need to use stronger boxes.
