The Samsung 29-inch freestanding top-freezer refrigerator offers a huge 18 cu. ft. of space, including a FlexZoneâ„¢ (a versatile fridge compartment that converts the freezer into a fridge). The doors are reversible, and this is a 29-inch rather than a standard 30-inch model, making this a flexible fit for most kitchen spaces. What’s more, it beats out most similarly sized models for energy-efficiency, using just 364 kWh/yr.

The refrigerator has 3 adjustable glass shelves that can slide in and flip up as needed, as well as a Slide & Reach pantry, 3 door bins, and 2 humidity controlled crispers. LED lighting make for energy-efficient illumination, and this refrigerator features Twin Cooling Plus™ which works to maintain optimal temperature and humidity, keeping food fresher longer. 

This model has an optional ice maker, automatic defrost, 2 glass shelves and 2 door bins in the freezer. It is not ADA compliant, but it does have a Star K certified Sabbath mode. And, importantly, the Samsung 29-inch freestanding top-freezer uses r600a as a coolant and pentane for insulation, instead of CFCs, HCFCs, or HFCs.

Samsung vs. Blomberg vs. Liebherr

The Samsung is an excellent energy-efficient refrigerator for anyone looking for that little bit extra space and/or a Star K certified model. It uses less energy than the Blomberg 30-inch refrigerator, but a little more than the more impressively eco-friendly high-performance Liebherr Monolith (View Price on Amazon). The Monolith also has a fantastic warranty and is RoHS and REACH compliant, but the Samsung has the advantage of being made in the US, which gives it some upfront eco-friendliness. All in all, if your money stretches to the Monolith and you don’t require a Sabbath mode, go for the Liebherr model, with its RoHS and REACH certifications and lower energy usage.
