The catch
Whynter ARC-147WF
HEPA replacement costs extra and brings airflow maintenance.
Side by side
Whynter ARC-147WF vs Whynter ARC-14S: 147WF comes with a HEPA stage and a little more adjusted cooling
Quick verdict
A documented HEPA stage is the reason to pick the ARC-147WF. Its 9,500 BTU SACC figure is slightly lower, but the ARC-14S is a simpler, established platform.
Before you buy
Why, and what it costs you
Where these two really part ways
Whynter ARC-147WF is the better match for “I want an actual HEPA stage” and “It will be running while I am asleep”. Whynter ARC-14S is the better match for “I have a medium room to cool” and “Seasonal installation should be simple”.
Where this comes from

The catch
Whynter ARC-14S
Next to an inverter, its fixed-speed compressor cycles on and off more abruptly.
