Whynter ARC-14S review

The ARC-14S is Whynter's long-running dual-hose model without an inverter. Whynter lists 14,000 BTU on ASHRAE and 9,500 BTU on the DOE 2017 standard, with coverage for spaces up to 500 sq ft. A dual-hose design pulls outside air in through one hose and pushes hot air out through the other, which keeps it from drawing warm air into the room through gaps. The filtration is better than most portables: an activated carbon filter and a washable pre-filter, with a 3M antimicrobial filter sold separately. Whynter lists dehumidifying at 71 pints per day and a patented auto drain function that exhausts condensate. Power draw is 1,300 watts at 11.6 amps, and the unit measures 16 by 19 by 35.5 inches. Noise is rated under 51 dBA on low and under 56 dBA on high, louder than the inverter models here, and there is no Wi-Fi. It lists at $509.99 on Whynter's store, but it was marked sold out when we checked.
