Our new filters are obviously well made and dust accumulation has been cut by 70% so you know the air quality is much better for all. Its a great thing.
The filter media is not attached to the cardboard frame. If anyone reads this check your filter very closely. Mine are separated at one or two corners. I had 2 out of 3 filters with this manufacturing defect. When they sent me a replacement it had the same problem and now no response.
