Does anyone have experience with the Flanders Precision Aire heavy duty polystrand filters? Also, the Glassfloss filters. They both say they hold dust well. I saw them on Amazon. I want to avoid the pleated filters as advised here due to concerns for damage to my new system with too much air flow restriction. I am getting a lot of dust in the house compared to when I used the Dust Fighter 95 electrostatic filters I used for 18 years with my old system which died this spring due to bad bearings and cracked heat exchanger. Thanks for any input on these filters.
