Coway Airmega Mighty AP-1512HH Air Purifier, Black
A bedroom or office up to about 361 sq ft, with 8 inches clear around it
Coway's AP-1512HH is a 16.8-inch-wide HEPA purifier with a washable pre-filter, a six-month odour filter and a one-year HEPA filter. The maker publishes CADR of 233 smoke, 246 dust and 240 pollen, and defines its own room figures by air changes per hour: 361 sq ft at 4.8 per hour, 874 at two, 1,748 at one. It wants 20 cm around it and 30 to 60 cm above.

- The '3yr warranty' is motor and electronics only; internal parts are one year, and non-genuine filters void coverage
