Fallen Short of Objective by Bob Julian (Shoreview MN US)

I am enthusiastic that this product will be valuable. Online postings suggested that installation was possible for a D-I-Yer. I'm a handy guy but have opted not to risk it. I'll wait for the next tune-up visit and have a pro install it.

General Aire G99 Air Filter Gage by Sybren Y Reitsma (Windsor On CA)

Great product that should be installed in every forced air heating and cooling system. Excellent manual for a low cost product. It costs less than a high quality air filter and prevents replacing a filter too soon or too late.
