Comparison

Compare air cleaners by the same criteria

Compare the same room and operating assumptions. Unknown values stay unknown.

How to use this checklist

Measure the room and use the room-volume calculator to note the airflow your chosen scenario implies.
For each option, copy each row from the manufacturer’s official specifications for the exact model.
Leave a cell blank until you have checked it. An unknown value stays unknown.
Use the same room, operating setting and time period for every option.

Worksheet

Write what the official source says for each option. Leave a cell blank until you have checked it.

Name the options you are comparing

Use the exact model name from the official source. Leave a name blank to keep the default.

A blank cell is a reason to check the official source, not evidence that the option fails. Compare the exact product and region before buying.

Limitations

CADR concerns particles; it should not be presented as a universal gas-removal or health-outcome measure.
The highest modeled airflow is not automatically the right purchase.
Record the noise specification only if the manufacturer sources it.
