LG CordZero Q3
Mid-range pick with a swappable battery
Suits up to 1,500 sq ft (139 m²)60 min rated at the lowest power. My threshold: 60 min or more for up to 1,500 sq ft, less than that up to 1,000 sq ft. No published standard exists.

If you buy through a link here, the store may pay me a commission. Your price stays the same. How that works.

My short take
Rated at 150 air watts with a quick-release battery and a HEPA filter. Abt lists 84 dB, the loudest of the sticks here that have a stated figure.
