This week I spoke with Ray Markey from Dynamic Air Quality Solutions in depth about their Dynamic V8 filter setup.  I was initially very interested in this product because of how low the loaded static pressure drop was (0.5"-0.7" at changeout in 5-7 years) and how much that can help us design air handlers with lower brake horsepower to make our Title 24 energy compliance easier.  Owners and service tech's will love it too.  We also discuss some cannabis solutions as well.  Enjoy.
