Do Air Filters Matters!

Good work Doug. I like the Aprilaire filters for their high efficiency and low pressure drop. I would even consider adding turning veins through the return drop ahead of the filter.

Agreed turning veins would have been great but not in clients budget. This is a great example on well designed air filter/setup can change equipment performance and your comfort.
