Calculations
- What is Air Exchanges per hour for a well-ventilated house? 3 for good quality. [9]
- CFM of 120 gets us one exchange per 20 minutes for a 2400 cf room (about 240 sf), so we have 3 AAH for [10]
Corded vs Plug-In
- If Corded, Needs Access Panel to Hide Cord
- It has a wall-wort [11]
- If hardwired, needs disconnect, but not if it's a small device under 300W [12], where the circuit breaker can be a lockable disconnect.
