Let's say we set our 4 ton system's low fan speed to 50% or 800 cfm. So this means we are moving a full 10'x10'x8' rooms worth of air every minute. In 25 min, it can recycle the air of an entire 2500sqft home with 8' ceilings. How is that not cleaning the air?
The MERV 16 is not that much more restrictive than the MERV 10.

The old model did have flaws with its UV bulb design, but they have a new U tube design that has a far less failure rate.
