What to know before buying
- · The MinusA2 can sit on the floor or be wall-mounted, and it ships with the bracket and hardware for wall installation.
- · Its negative-ion stage is defeatable: you turn the ionizer on or off by pressing and holding the mood-light button, and the unit remembers the setting.
