Product review (2 stars): Too good?
I replaced the stock paper and foam filter in my Red Devil vacuum with this product, but it seems that it is TOO restrictive to the airflow. The vacuum does a very poor job at picking up since replacing the filter, and I feel the brushes shooting particles back at my feet and ankles rather than getting sucked up by the vacuum. There seems to be far more dust on the Honeywell foam filter than with the original, which would be great if it didn't result in far fewer big particles and objects from being picked up.
