RichnVinny and Dave,
Where would a better location be for the filter? I'd be happy to pass the feedback onto Tom.
Personally, I run a 2-stage system. Two whole-house filters are larger than I want to put in the UDC, so I put then behind the utility wall and made my wall easily removable witout tools. Also, I feel the filters will stay warmer behind the wall than they will in the storage bay or UDC.
What if a modification was made to the utility wall "at the factory" where it was easier to enter? And maybe bolt the filter to the back of the UDC where it was easier to reach in and service?
Looking forward to your ideas. Thanks guys.
