2. Power and RPM

The main idea of a garbage disposal unit is to finely grind the food wastes so that they can easily pass through the sewerage. So, the capacity of the motor should be competent enough to perform the task. The better the capacity of the motor, the enhanced the RPM. The motor capacity of garbage disposal ranges from 1/2hp, ¾ hp or 1 hp. With better efficiency, the chance is better, that even the toughest of the food scraps will not stand a chance.

Everything will be finely ground and crushed with ease within a matter of seconds. A high powered motor will utilize less time for better delivery. This will also reduce the possibility of irritating noise production for a longer duration.

3. Sound Masking Systems

SoundSeal Technology is the most popular in this genre. With the advent of better insulation and sound masking technologies, the garbage disposal units have become much quieter in recent days. Any standard garbage disposal model produces a noise of around 80 dB. But the modern range of quietest garbage disposals produces a noise of no more than 45 dB. These machines are better insulated and produce less vibration. Lesser levels of vibration also reduce the tendency of high noise production.

Too much of noise creates a lot of disturbances and hampers natural human conversation. But with these soundproof models, all these problems do not stand a chance.

4. Feed Type

Most of the garbage disposal units are continuous feed type. This allows you to keep on adding the food wastes even while the machine is running. The models which are not continuous feed type are known as batch feed type. These types of machines do not allow loading during functioning. Once the machine is fully laden, it will run when the switch is turned on. Once that batch is completed only then you can add the second load. But most of the batch feed models run the risk of getting overloaded. The continuous feed types have a lesser chance of the occurrence of this sort of problem.

5. Warranty

Most of the garbage disposal units, quiet range or not, come with a lenient warranty period. The term of this warranty ranges from 7-10 years depending on the make and model of the machine. There are even some units available that have a lifelong limited in-home warranty period. Brands like InSinkErator and Waste King lead the market with the most generous warranty periods. 

However, whatever the time period of the warranty may be, it does not cover the damage caused by the natural wear and tear or cosmetic corrosion, or damages caused by your negligence or mistake while installing, replacing or merely using the product.

While buying, the warranty period should be considered. The term of the warranty is in itself an indicator of the durability of the product.
