Frigidaire FFAD3033R1 vs FFAD7033R1: 30 or 70 pints?

Frigidaire model comparison

The discontinued FFAD3033R1 and FFAD7033R1 share an older control and drainage family, but they are not the same appliance in a different label. Their rated capacity, bucket size, airflow, footprint and published sound figures differ. Both should be treated as identification references for existing units, not as new-purchase choices.

Start with the exact suffix

The exact U.S. Frigidaire support pages identify FFAD3033R1 as a 30-pint “Small Room” unit and FFAD7033R1 as a 70-pint model. Both pages say discontinued and link a version 06/20 product specification sheet plus a shared Use & Care guide. The documents' overlap makes it reasonable to compare the models' operating family, but it does not erase the suffix difference or transfer a number from one appliance to another.

The same 30-pint specification sheet also lists FFAD3033RE. Frigidaire Canada's exact support page identifies that suffix as a discontinued Canadian 30-pint variant. It lists 36.1 pounds and ENERGY STAR certification; the U.S. FFAD3033R1 page lists 34 pounds, and its sheet does not state an ENERGY STAR result. Keep each value attached to its exact model and market. Neither Canadian certification nor Canadian weight is used to describe the U.S. R1.

Capacity and tank volume change together

The 30-pint/day sheet gives FFAD3033R1 a 7.6-pint front bucket. The 70-pint/day FFAD7033R1 sheet lists a 13.1-pint bucket. That is about 1.7 times the stated collection volume, but it is not a direct measure of how many hours either tank lasts: water production varies with room conditions. Both use a bucket-full shutoff and require an owner to empty and reseat the tank. The larger bucket can reduce interruptions when collection is high, while also holding more weight when full.

Both exact sheets list continuous drainage. The shared manual describes attaching a garden hose and routing it toward a nearby drain without kinks or elevations. That means gravity and a usable downward slope. The exact materials do not specify a pump-lift limit or document bucketless operation, so neither model should be selected for an uphill drain or tank-free plan on this evidence.

Footprint, airflow and sound figures

The 30-pint R1 measures 20 1/2 inches deep, 13 13/16 inches high and 10 1/4 inches wide; Frigidaire lists 34 pounds on its U.S. page. The 70-pint model is 24 7/16 inches deep, 15 1/16 inches high and 11 9/16 inches wide; its exact page lists 46.5 pounds. Check doorways, the route for emptying a bucket and the space needed for the side drain cover before carrying an older unit into position. The manual separately calls for at least 12 inches of clearance, so cabinet size is not the full operating envelope.

The smaller model's specification lists 100/124 CFM at low/high and 52 dBA at high; the larger lists 159/182 CFM and 51 dBA at high. These are manufacturer values, not comparative testing. The higher airflow rating does not guarantee better results in every room, and a one-decibel difference should not be read as a controlled quietness verdict. Each sheet gives three speeds, a 35–85% humidity-setting range and a washable rear filter. The old guide recommends cleaning the filter every two weeks and calls for a level, enclosed placement within 41–90°F.

Which assessment fits your situation?

• Read the FFAD3033R1 review when a nameplate or listing points to the 30-pint U.S. model, or when checking the separate Canadian RE distinction.
• Use the FFAD7033R1 review when identifying the larger 70-pint unit and verifying its 13.1-pint tank, body dimensions and gravity route.
• If buying a current appliance instead, compare a current-reference model on the feature that matters most. The FHDD3534Y1 is a separately assessed 35-pint Frigidaire model with Wi-Fi and a gravity-only plan; the FHDP6033W1 has a separately documented pump route. Neither one's details transfer to an FFAD-R1.

For any old dehumidifier, verify the label and manual edition before replacing parts or planning a hose route. Room-area names and pints-per-day ratings do not replace the actual installation instructions, and a dehumidifier does not fix water entering the building.
