BOSCH: 5 DOE certified models
BOSCH has 5 basic models certified to DOE as of 2026-11-03: 2 dehumidifiers (23 to 35.94 pints/day under the 2019 DOE test) and 3 air purifiers (smoke CADR 86 to 339 cfm). How their efficiency compares with their DOE class is below.
Key findings
- Highest certified water removal among its dehumidifiers: BOSCH Dry 4000 at 35.94 pints/day.
- Highest certified smoke CADR among its air purifiers: BOSCH Air 6000 at 339 cfm.
- Most efficient for its class: BOSCH Air 4000, CADR/W 7.7, higher than 125 of the 140 in its DOE class (air purifiers, PM2.5 CADR 150+ cfm).

How efficient are BOSCH models?
Dehumidifiers
Of the 2 BOSCH dehumidifiers, 1 files a higher IEF than the class median and 1 matches it.
| DOE class | BOSCH models | Above median | Class median | Best BOSCH |
|---|---|---|---|---|
| Portable dehumidifiers up to 25 pints/day (253) | 1 | 0 | IEF 1.7 | Dry 2000 IEF 1.7 |
| Portable dehumidifiers, 25 to 50 pints/day (296) | 1 | 1 | IEF 1.91 | Dry 4000 IEF 2.01 |
Air purifiers
Of the 3 BOSCH air purifiers, 3 file a higher CADR/W than the class median.
| DOE class | BOSCH models | Above median | Class median | Best BOSCH |
|---|---|---|---|---|
| Air purifiers, PM2.5 CADR 150+ cfm (140) | 2 | 2 | CADR/W 5.5 | Air 4000 CADR/W 7.7 |
| Air purifiers, PM2.5 CADR 10 to 99 cfm (90) | 1 | 1 | CADR/W 3.5 | Air 2000 CADR/W 5.3 |
A higher IEF means more water removed per kWh. A higher CADR/W means more clean air per watt.
Who makes BOSCH dehumidifiers and air purifiers?
DOE's database has no manufacturer field, so the evidence is whose model number each unit is filed under and which other brands file the same unit.
None of the 5 BOSCH basic models is filed by another brand as of 2026-11-03, and none uses another company's model number. DOE's records tie them to BOSCH alone.
How much do BOSCH models cost to run?
Running nonstop at DOE's test conditions, the 2 BOSCH dehumidifiers with both figures use 6.4 to 8.46 kWh a day. That's about $1.16 to $1.54 a day, or $34.88 to $46.09 for 30 days. The lowest is BOSCH Dry 2000 (23 pints/day, IEF 1.7) and the highest BOSCH Dry 4000 (35.94 pints/day, IEF 2.01).
DOE's annual energy figures for the 3 BOSCH air purifiers that file one run from 103 to 289 kWh a year: about $18.70 to $52.48 a year. The lowest is BOSCH Air 2000 (86 cfm, CADR/W 5.3) and the highest BOSCH Air 6000 (339 cfm, CADR/W 6.9).
Real use cycles on and off with the humidity, so the dehumidifier figures are the upper end for a day of nonstop running.

Questions about BOSCH
- Is BOSCH a good dehumidifier brand?
- How its 2 dehumidifiers compare on efficiency with their DOE class is above. Both are filed under BOSCH alone. We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
- Does BOSCH make a 50 pint dehumidifier?
- No current DOE record shows one as of 2026-11-03. Its largest, BOSCH Dry 4000, certifies 35.94 pints/day under the 2019 DOE test. Boxes that quote the older 80°F test read higher for the same unit. By DOE class: 1 in the up to 25 pints/day class and 1 in the 25 to 50 pints/day class. How the 2019 test changed pint ratings.
- Which BOSCH dehumidifier is the most efficient for its size?
- BOSCH Dry 4000, at IEF 2.01: higher than 161 of the 296 in its DOE class (portable dehumidifiers, 25 to 50 pints/day). At the other end is BOSCH Dry 2000, at IEF 1.7, higher than 94 of the 253 in its class.
