It’s important that you spend your time before you spend your money. A little research can save you a lot of money on the long run and it can make sure that you will be satisfied with your purchase at the end. If you choose wisely, a disposal unit can serve you and your family for years to come.

Garbage disposal unit capacity

First, you should consider capacity of the machine. Units with greater capacity will be more powerful and able to grind larger amounts of food waste, but they will also be more expensive.

We suggest that if you live alone you should consider to choose a unit with capacity. Capacity of garbage disposals start with 1/3 HP, but we advise to look for at least 1/2 HP. If there are many people in the house, you may need bigger unit and you should consider to look for a machine with 1 HP. Keep in mind that selection of unit capacity is not only related to the purchase price but also to electrical consumption.


The second factor you should take into consideration is the material. Garbage disposal machines can last for quite some time, even up to 20 years. Therefore you should choose a unit made of  materials which can survive for a long time. We believe that stainless steel is one of the best materials used for garbage disposals. Although it can be more expensive than alternatives at first, it can easily be a more affordable choice on the long run. The last thing you want is your disposal unit to start rusting after just a few months of use.
