Our Review
The Microfridge 31MF7R 3 cu. ft. Compact is a 3.1 cu. ft. compact refrigerator from Microfridge, sitting in the sub-$1,000 range. With a 2.6 cu. ft. fresh-food compartment and 0.5 cu. ft. of freezer space, it's positioned for apartments and dorms.
What stands out
This is squarely a mainstream model — Microfridge optimizes for value, parts availability, and a feature set that covers what most households actually use. You won't find exotic materials, but everything that ships works as advertised.
ENERGY STAR Most Efficient certification means it sits in the top ~10% of the category for energy use. At ~195 kWh/year, expect roughly $31 in annual running cost at the U.S. average electricity rate — meaningfully less than older models from a decade ago.
Layout and capacity
Exterior dimensions are 18.5" W × 32.9" H × 22.0" D — check your opening, especially the depth with handles extended. Total useable capacity is 3.1 cu. ft., split 2.6 fresh / 0.5 freezer.
Bottom line
The Microfridge 31MF7R 3 cu. ft. Compact is a strong mainstream choice — most of what people actually use a fridge for, at a price that makes sense. Service parts are widely available.
