Dreo Dehumidifier 733S review

The Dreo 733S ranks first because it is the only full-size compressor model here that pairs a published noise figure, 42 dB, with a large tank and app control at under $300. Dreo sells it in 73-pint and 95-pint sizes, and the 73-pint version was $279.99 on Dreo's US store when we checked. The spec table lists 2,000 sq ft of floor coverage, 163 CFM of airflow, auto mode, auto defrost and a 1.85 gallon (7L) tank, and the box includes a drain hose for continuous gravity drainage. The DREO app adds real-time energy and cost tracking, which is useful for a unit that may run for months in a basement. The trade-offs: there is no pump, so the drain point has to be lower than the unit, and Dreo quotes capacity as a 22 to 73 pint range without naming test conditions for each figure. We compared documented features and published prices.
