Here are some things to think about when you’re choosing a garbage disposal unit:
Units come in different sizes. The size you should choose depends on the size of your sink. If you don’t have a lot of space underneath your sink, you might want to opt for a more compact unit.
The motor size
The best garbage disposal units come with the most powerful motors. If you plan on using it often, or you tend to have a lot of hard food wastage, make sure you choose a powerful motor. Raven Lounge has made a list of some of the best garbage disposal units with powerful motors.
A third thing to consider is the noise. How noisy do the units claim to be? The quieter, the better. You can also consult product reviews from previous customers to get a measure of this.
