this is a copy of what carrier put out against the cleaneffects, and it is tranes response. kinda hard to read, but it can be seen.
cleaneffects is head and shoulders above an eac, the industry cannot compete with this "whole" house air cleaner, and in such a least restrictive way.
filters should be sold properly, not promised or suggested at their potential. hence, uv lights, sold to be a cure all. if sold properly, they wouldn't be such a hot seller. uv's don't clean air as many jabronis sell em to.
