We also measured power draw at a more moderate humidity level (right around 50% relative humidity).įirst, we saw a lot more variance in tested wattage between different models. By erring on the side of caution and specifying a slightly inflated amperage, the manufacturer is allowing for more safe use of their appliance. It’s not unreasonable to believe manufacturers are giving power draw in amps simply so that you can estimate safe use of their appliance on a 15 amp circuit. We calculated the watts listed above by multiplying the given amperage by 115 (volts). Remember, all manufacturer specifications are given in amps. involves running the dehumidifier in even more extreme conditions than what we can emulate in our own “extreme humidity” testing orī.

This, of course, is less than the 897 watts the FFAD5033W1 is rated for, suggesting that the manufacturer specification either…Ī. 760 watts at extreme humidity levels (close to 100% RH). Our own testing revealed all of these units to have a similar power draw of approx. The LG UD501KOG5 (6.3 amps = 725 watts) and hOmeLabs HME020031N (6.5 amps = 745 watts) are some examples of units that fall in the lower end of the range. The Hisense DH7019K1G (7.8 amps = 897 watts) and Toshiba TDDP5012ES2 (7.8 amps = 897 watts) are a few other examples of units that fall in the upper end of the range. This falls in the upper end of the range for 50 pint dehumidifiers. The FFAD5033W1 has a manufacturer specified power draw of 7.8 amps (897 watts). Performance Test Results Energy Efficiency At Extreme Humidity We compare it to all of the other 50 pint dehumidifiers we’ve tested throughout the review. In the review that follows we look more deeply into all of the FFAD5033W1′s test results as well as its key features and functionality. A dehumidifier’s job is to dehumidify and the FFAD5033W1 simply dehumidifies faster and more efficiently than any other 50 pint dehumidifier we’ve tested – and we’ve tested many such units (27 high capacity units alone). Otherwise, the FFAD5033W1 follows right in line with what made the FFAD7033R1 our top pick in previous years: it was an outstanding performer in all four of our real world performance tests and most importantly, it was the top performer in our moisture removal test. Such an attachment is no longer needed with the FFAD5033W1 (a garden hose is connected directly to the drain outlet shown on the right in the photo). It now has the largest tank of any 50 pint dehumidifier currently on the market (at least as of the writing of this review).Īnother FFAD7033R1 shortcoming was the fact that you needed to attach an adapter to its side drain plug to connect a garden hose for gravity drainage (the adapter extends out of the side of the unit on the left in the photo). The FFAD5033W1’s tank (right in photo) has a capacity of 16.9 pints. The FFAD7033R1’s small 13.1 pint tank (left in photo below) was one of its few shortcomings. The latest Frigidaire dehumidifier, the FFAD5033W1, adds two notable improvements over its predecessor, the FFAD7033R1 – a much larger water tank and it also no longer requires an adapter to employ gravity drainage.

Both would be 70 pint dehumidifiers under old standards.

Note that both units are 50 pint dehumidifiers according to current government (Department of Energy – DOE) standards for stating pints/day capacity. The Frigidaire FFAD5033W1 replaces the now discontinued FFAD7033R1 (left in the photo below) as the best dehumidifier in 2022.
