The Whynter ARC-147WF is a conventional dual-hose portable with a twist: it filters the air as well as cooling it. Whynter rates it at 14,000 BTU with 10,000 BTU SACC for rooms up to 500 square feet, and it ships with a HEPA filter, an activated carbon air filter and a washable pre-filter. It is a simpler, non-inverter alternative to the smart models in our dual-hose portable air conditioners category, with a 3.6 out of 5 average from 12 ratings so far.
It runs on a standard 115 volt outlet, draws up to 1341 watts at 11.8 amps, and works as an air conditioner, a dehumidifier or a fan.
Our Verdict
The ARC-147WF makes sense for a bedroom, office or medium living room where air quality matters as much as cooling. The 10,000 BTU SACC rating is solid for 500 square feet, the dual-hose layout avoids pulling warm air in through gaps, and the HEPA filter is rare on a portable air conditioner. Whynter’s auto drain also handles condensate in most environments.
The trade-offs are efficiency and noise compared with inverter models. It uses a conventional rotary compressor, lists a SEER of 7.83 and runs at 51 dBA on low speed. It also weighs 77 pounds. If you want a filter-first dual-hose unit and do not need Wi-Fi, it is a sensible choice.

Cooling Capacity and Room Size
The 14,000 BTU figure is the headline number, while the 10,000 BTU SACC figure reflects real-world use and is the better one for sizing. Whynter matches the ARC-147WF to rooms up to 500 square feet, which covers most primary bedrooms, home offices and medium living rooms.
Airflow is listed at 460 cubic meters per hour, or 270 CFM, and full thermostatic control runs from 61 to 89 degrees F. Because the compressor is a conventional type, it runs at full output and then cycles off when the room reaches the set point. Expect slightly bigger temperature swings than you would get from an inverter unit.
Dual-Hose Design and Installation
With two hoses, one pulls outdoor air in to cool the condenser and the other sends the hot air back out. The unit does not use your already cooled room air for that job, so it does not draw warm air in under doors and around windows the way a single-hose portable can.
The box includes an extendable exhaust hose up to 59 inches long with a 5.9 inch diameter, and a window kit that is 6.5 inches wide and extends from 20 to 46 inches. That suits most standard sliding and double-hung windows, though very tall windows may need an extra panel. The indoor unit measures 17.74 inches wide, 15.81 inches deep and 30.87 inches tall, and it rolls on caster wheels. A storage cover bag is included for the off-season.
Noise, Energy Use and Efficiency
Whynter lists 51 dBA in low speed. That is acceptable for a bedroom with the door closed, but it is louder than the inverter models in this category, which list noticeably lower figures.
Maximum draw is 1341 watts. The listed SEER of 7.83 is typical for a conventional portable, so running costs will be higher than an inverter unit that cools the same space. In return, the purchase price is usually lower, and a conventional compressor is a simple, proven design. If you only run the unit on the hottest afternoons rather than all day, the gap in running costs matters less, and the lower upfront cost can make the ARC-147WF the better value overall.
Controls and Filtration
Controls are simple. There are three modes, cool, dehumidify and fan, three fan speeds and a remote. There is no app, Wi-Fi or voice control, which some people will see as a plus.
Filtration is where the ARC-147WF stands out. The HEPA filter captures fine particles, the activated carbon filter helps with odors, and the washable pre-filter catches larger dust and hair before it reaches the others. Rinse the pre-filter often, and check the HEPA and carbon filters through the season.
Dehumidifying and Drainage
Whynter’s patented auto drain function exhausts all condensate in most environments, so daily draining is not usually needed. In dehumidify mode the unit can remove up to 134 pints per day, which is a high figure for a portable and helpful in damp basements or muggy summers.
Who It Suits Best
The ARC-147WF suits a household that wants cleaner air along with cooling, such as allergy sufferers, pet owners or anyone living near a busy road. It is also a good match for people who prefer a plain remote over an app. It is less suited to light sleepers, smart home users and anyone who wants the lowest possible running costs.
