The catch
Dreo Portable AC 516S
Replacement air still gets drawn in through the building envelope because of the single hose.
Side by side
App control and a window opening within the 18 to 53 inch range point to the Dreo 516S. Dual-hose operation and the HEPA filter that comes with it point to the Whynter ARC-147WF. Both are listed at 10,000 BTU adjusted cooling, so neither one wins on a higher headline number.
Before you buy
Whynter's range stops at 46, while Dreo's standard range includes 50 inches. Even if dual hoses are your preferred design, the Whynter would need a confirmed compatible extension or panel solution.
Where this comes from
50 - 46 = 4 inches beyond the Whynter kit. Do not improvise, whether by stretching a hose or leaving a gap in the panel.
The catch
Replacement air still gets drawn in through the building envelope because of the single hose.
The catch
HEPA replacement costs extra and brings airflow maintenance.

Dreo AC516S and Whynter ARC-147WF go head to head on 10,000-BTU cooling, short windows, hose layout and drainage in a humid room.

Which one fits
The Dreo kit goes farther.
The standard Whynter range begins at 20 inches.
Intake and exhaust each get their own hose on Whynter.
The filter comes with Whynter, and no room-purification claim goes with it.
How condensate behaves depends on conditions and operating mode.
In practice
Whynter's range stops at 46, while Dreo's standard range includes 50 inches. Even if dual hoses are your preferred design, the Whynter would need a confirmed compatible extension or panel solution.
50 - 46 = 4 inches beyond the Whynter kit. Do not improvise, whether by stretching a hose or leaving a gap in the panel.
Whynter comes with HEPA media, though both need their filters kept clear. That may shape the filter-care routine, yet there is no matched CADR or acoustic evidence here to call it the better allergy or sleeping appliance.
Filter packages and sound claims from the manufacturer are recorded on their own. No result for symptoms or quietness is inferred.
Each publishes 10,000 adjusted BTU, but the air paths are not alike. Choosing Whynter means choosing outdoor condenser intake, and not an extra 4,000 BTU over Dreo's listing.
Single-hose operation is confirmed by Dreo, and Whynter lists two hoses. SACC is tied and is not added to ASHRAE.

Dreo, DR-HAC006S
Smart Dreo at 10,000 BTU SACC that gives a 400-square-foot room extra cooling reserve.

Whynter, ARC-147WF
A dual-hose unit rated 10,000 BTU SACC, with HEPA and activated-carbon filtration added.
Spec by spec
| Spec | Dreo Portable AC 516S | Whynter ARC-147WF | In practice |
|---|---|---|---|
| Adjusted cooling | 10,000 BTU DOE/SACC | 10,000 BTU SACC | On rated cooling, they tie. |
| Air path | Single exhaust hose | Separate intake and exhaust hoses | Room air is not the only condenser-air source for Whynter. |
| Window-kit range | 18 to 53 in | 20 to 46 in | Within the published ranges, Dreo handles both shorter and longer openings. |
| Filter package | Washable air filter | HEPA and activated carbon | Room air-purifier performance is not established by the filter choice. |
| Night-sound claim | 46 dB manufacturer-listed low figure | Below 51 dBA low figure | Conditions set by different manufacturers do not prove a measured noise advantage. |
| Cooling condensate claim | Self evaporation below 85% humidity | Auto-drain evaporation in suitable conditions | Water management may still be needed in high humidity. |
Trade-offs
Change of plan
Go with Dreo Portable AC 516S. No longer panel is needed, since the stated Dreo kit covers it.
Go with Whynter ARC-147WF. Those features are documented for ARC-147WF.
Decision guide
The Dreo 516S fits if you want app control and your window opening falls within its 18 to 53 inch range. The Whynter ARC-147WF fits if you want dual-hose operation and its supplied HEPA filter. A higher headline number does not separate them, since both are listed at 10,000 BTU adjusted cooling.
Coming up four inches short on the panel is a real installation problem in a rental. Check the opening and the pieces supplied before you think about optional modifications. Even the best hose design is no use if it cannot be installed correctly.
The ARC-147WF comes with a different filter package, and Dreo publishes a lower sound figure for its low setting. Neither amounts to a matched bedroom result. If noise sensitivity is central for you, think about the cleaning routine, placement and return policy.
Under the conditions the manufacturer states, self-evaporation cuts down on how much you have to handle the water. It does not promise a water tray that stays dry for good. Keep the drain within reach, and learn the full-water procedure before you leave the unit running while you sleep.
