BLACK+DECKER BPP05WTB vs BPP06WTB: 5,000 or 6,000 SACC?
BPP05WTB and BPP06WTB share a BLACK+DECKER manual family, one-hose setup and much of the same control and water-management design. The documented distinction that matters first is 5,000 versus 6,000 BTU/h SACC—not the separate 8,000 and 10,000 ASHRAE figures.
Start with the room’s heat load and a consistent rating
The BPP05WTB is listed at 5,000 BTU/h SACC / 8,000 BTU/h ASHRAE and the manual pairs that class with rooms up to 150 square feet. The BPP06WTB is 6,000 SACC / 10,000 ASHRAE and the manual’s size guide says up to 250 square feet; its exact product page repeats that estimate. These numbers are not interchangeable rating methods. A minimum of 5,000 SACC can admit both, while a 6,000-SACC minimum admits only BPP06WTB and a 7,100 minimum admits neither. The claimed area is a rough guide, not a promise of performance for a sunny, leaky, unusually tall or open room.
For a third point of comparison, the distinct BP06PWA is another 6,000-SACC unit with a separate manual and product code. Do not confuse it with BPP06WTB: similar numbers do not make their dimensions, supplied parts or identifiers interchangeable. A family label or the word “portable” is not enough to merge model records.
The main operating plan is similar, but drainage still needs attention
Both BPP models use a single exhaust hose. It belongs in the window opening for cooling and dehumidifying, while the family manual says to disconnect it during Fan mode. Their slider is documented from 27.5 through 47.2 inches in vertical or horizontal window installations; the manual also discusses shortening a panel for narrower openings, but does not give a minimum after cutting. If the opening is outside the printed span, treat it as a fit question for a careful installer rather than assuming an unlisted endpoint.
The matched family manual documents Cool, Dehumidify and Fan operation for BPP05WTB and BPP06WTB. The heating instructions and heat symbol apply only to BPP08HWTB and BPP10HWTB. For these two smaller cooling-only suffixes, do not buy one as winter heat. Both have a remote, timer, washable filter, fan speeds and automatic evaporation. That does not mean water never needs handling: high humidity can produce a full-tank warning and stop cooling. A supplied hose can provide downward gravity drainage to a floor drain or tray; no built-in lift pump is documented. Continuous drainage is especially relevant if running Dehumidify for long periods.
Room fit and moving the cabinet
The manufacturer’s listed width is 17.32 inches and its height is about 27.2 inches for both models. Their cabinet depth is unsettled: the support/product pages say 13.2 inches, while the family manual says 14.05. The BPP05WTB support page and manual agree on 51.1 pounds. BPP06WTB’s manual and support page say 54.8 pounds, but the current brand storefront page displays 12.1 pounds; treat BPP06 net weight as unresolved instead of relying on the discrepant field. The casters aid placement on smooth flooring, but do not remove the issue of lifting either machine over stairs or a threshold.
The BPP05WTB page lists 860 watts, 7.6 amps working and 33 amps start-up; BPP06WTB lists 1,050 watts, 9.5 amps working and 36 amps start-up. Those are model-specific support specifications, not efficiency scores. The exact CEER/annual-energy label is not established for either model, so these watt and current listings do not prove one is more efficient. The BPP06 manufacturer page additionally states a 52-dBA high-setting figure and up to 60 pints/day of dehumidification; those are maker claims rather than independent measurements.
Care and which alternative fits your answer
The family manual calls for weekly filter cleaning, at least 12 inches of air path around the cabinet and a grounded nominal 120-volt outlet; it says not to use an adapter or extension cord. It lists Cool and Dehumidify room operation between 64°F and 95°F. A window seal, short hose and suitable outlet are part of the installation plan, not optional accessories. Do not assume app control or an inverter compressor just because a listing uses “smart” language for a different code.
Pick BPP05WTB when a 5,000-SACC small-room tier suffices and its verified 51.1-pound support/manual weight is useful to know. Pick BPP06WTB when its extra 1,000 SACC is needed and a 250-square-foot manufacturer estimate is directionally right; use another model if known weight or depth is a strict requirement. If you need a documented 6,000-SACC alternative with a different exact record, review BP06PWA alongside it. If you need heat, an integrated pump, app control or an exact CEER minimum, neither BPP05WTB nor BPP06WTB has evidence for that requirement. Use the exact retail model search; the manufacturer store’s BPP06 record was unavailable when checked, and the BPP05 model lacked a matching storefront SKU record. Neither statement implies current seller stock or price.
Read the individual BPP05WTB review and BPP06WTB review before comparing exact offers. Check the rear label and window-kit parts against the model you are considering.
