Exact variant	US AP-1512HH / AP-1512HH(W)	HealthMate standard model
Dimensions	16.8 × 18.3 × 9.6 in (width × height × depth), or 43 × 46 × 24 cm. It weighs 12.3 lb (5.5 kg).	14.5 L × 14.5 W × 23 H in; 47 lb.
Installation	No installation. It sits on the floor and plugs into a standard 120 V outlet. The manual asks for at least 20 cm (about 8 in) from walls and other objects. Leave 30 to 60 cm of open space above it. Keep it 2 m from a TV or other electronics, off sloped surfaces and out of direct sunlight. It's meant for indoor household use.	No installation. It plugs into a standard 120 V outlet. Austin Air says to set it on a flat, dry, stable surface at least four inches from any wall, with the vent facing away from the wall. It's meant to run 24/7.
Materials	Four stages: a washable pre-filter, a deodorization filter, a HEPA filter and a bipolar device. The manual calls that last stage the ionizer and gives it its own on/off button. The filter set page describes the deodorization filters as carbon filters for odors and gases.	Steel housing with a 360° perforated intake and a baked-on powder-coat finish. The filter has a large-particle pre-filter, a medium-particle pre-filter, over 780 cubic inches of activated carbon and zeolite (up to 15 lb), and 60 sq ft of HEPA media.
Warranty	Coway's manual covers the motor and electronic parts for 3 years from the original retail purchase. Internal and functional parts get 1 year. Coway's support list also puts the AP-1512HH under 3-year coverage. Claims need proof of purchase and a video of the problem. Filters aren't listed as covered. Problems caused by non-genuine filters, skipped filter changes, or commercial or office use are excluded.	Five years on the unit against defects in material and workmanship, under normal home use. Coverage depends on returning the warranty registration. The filter has its own five-year pro-rated warranty, and Austin Air doesn't explain how the pro-rating works.
Returns	The product page offers a 30-day money-back guarantee and "30 days free return", with an asterisk pointing to the return policy. That policy gives you 30 days from the ship date to request a return. It also says you pay shipping, handling and processing costs unless Coway made the error. If parts are missing, Coway may charge a restocking fee of 15% of the price or the value of the missing parts, whichever is higher. Refunds go to the original payment method. The policy doesn't say whether opened filters can be returned.	30-day money-back guarantee, no questions asked. Austin Air doesn't say who pays return shipping.
Unresolved questions	Whether it's listed in AHAM's Verifide directory or Energy Star's certified product list; neither could be checked Whether CARB certified the AP-1512HH; the readable part of CARB's list stopped at entries from November 2025 Power draw on low and Eco, and which speed the 77 W figure refers to Noise at each fan speed Standby power Whether opened filters can be returned What differs inside the Allergen, Intense Smoke and Pet filter sets	CADR for smoke, dust and pollen, and the room size it suits Power draw at each speed, so running cost is unknown Noise at each speed How the pro-rated filter warranty is calculated Why Austin Air's two stores list different prices Whether it's in AHAM's Verifide directory or on CARB's certified list
