How We Compare Models
Three factors shape every comparison: CADR airflow rates, filter replacement frequency, and energy consumption.
CADR Airflow
Clean Air Delivery Rate shows how quickly a purifier cleans a room of a given size.
Filter Replacement
Replacement frequency and filter cost determine the true ongoing expense of ownership.
Energy Consumption
Power draw across fan speeds reveals how a model will affect your electricity bill.
