Infinity Air Purifier
Whole-house purification in the ductwork.
The one-inch filter at your return grille exists to keep dust off the blower wheel. It was never intended to clean the air you breathe.
A whole-house air cleaner is a different thing entirely: a deep media cabinet or an electronic cleaner installed in the ductwork, with far more surface area. More surface area is the key point, because it captures much finer particles without adding the airflow resistance that a dense filter forced into a one-inch slot creates.
That resistance is a common problem. Putting the highest-MERV filter that will fit into a standard rack starves the system of air, which costs efficiency, hurts comfort and shortens the life of the blower and the compressor.
At a glance
- Installed in the ductwork, not the return grille
- Sized for surface area, not just MERV rating
- Long service intervals, typically annual

How to choose
A filter and an air cleaner do different jobs
Protects the blower
The one-inch filter at the grille
- Exists to keep dust off the blower wheel
- A dense high-MERV filter forced into the slot starves the system of air
- Costs efficiency and comfort, and shortens equipment life
Protects you
A whole-house air cleaner
- A deep media cabinet or electronic cleaner in the ductwork
- Far more surface area, so it captures finer particles
- Without the airflow resistance, checked by measuring static pressure
