Re: Furnace filter
No, as long as the filter is kept clean, there will be little restriction. I used this method at my last house that had the return air at the floor just inside the garage door. I had a woodshop in the garage, so there was a little extra dust that came in right where the grill was. After installing a filter there, the furnace filter life significantly increased. We also ran our furnace fan almost 24/7 as it was used to circulate the air in the house in addition to any heating or cooling needs.
