The choice of refrigerator you want to buy will depend on the number of people in the house as well as your food habits. Roughly a two member family would require anywhere between 50 to 200 litres. However, if you like your steak and chilled beer you might want a higher capacity refrigerator. Also if you are the kind who likes their weekly Sunday grocery shopping a larger capacity will be useful.

Refrigerator types are simple like direct cool and frost-free refrigerator. Direct cooling ones are mostly single door refrigerators and frost-free refrigerators are mostly double and multiple doors. The abundant variety comes in the form of capacity. You can choose from mini, small, medium and large refrigerators.

- Mini (50 to 100 litres) : These are really small, single door refrigerators just enough for one person to store the occasional can of beer and juices along with bare food items.

- Small (170 to 200 litres) : just right for a couple or even a small kitchen. You would go for this if you were on a tight budget. These are single door refrigerators.

- Medium (200 to 450 litres) : This is for the nuclear household. Reasonably priced these provide ample storage with enough features that are value for money. These could be single as well as double refrigerators.

- Large (450 to 800 litres) : For the big home and big budget. You would go for this if you have a large household and are really fond of throwing elaborate dos. The large sized could be double door, three door, bottom mounted, side-by-side.

Refrigerators should stay at 4.5*C or less. A temperature of 4.5*C or less is important because it slows the growth of most bacteria. The temperature won't kill the bacteria, but it will keep them from multiplying, and the fewer there are, the less likely you are to get sick from them.
