Waste King

Waste King seems to be targeting a specific audience. This is because their garbage disposals tend to be more expensive than the InSinkErator models. Most of their garbage disposals would be around $150.

As for the motor, Waste King utilizes the PMM motors in them. This technology is slowly taking over, but it seems like you can only get induction motors in the InSinkErator models. The PMM motors can spin at a higher speed of up to 2800 RPM. This makes it easier to go through even the toughest food waste.

As for the grind chamber, there is nothing much to mention. It is like any other grind chamber that you can get with a garbage disposal. The quality of the parts is relatively standard for the price. For the stronger models, the manufacturer implemented them with stainless steel parts to live up to the power.

The noise level is still high like any other garbage disposal. Waste King has not done much over the years to reduce the noise level of their garbage disposals. However, it is worth mentioning that InSinkErator models are louder.

Waste King offers the clients a lot more options to choose from in terms of size. This is where the company struck gold as you can always have an easy time picking a model that fits well with your needs and kitchen size.

InSinkErator disposals come with a Dura-drive Induction motor. The motor is designed exclusively for handling food disposal. Although most companies are now switching to PMM motors, it seems like this one is still using the induction motors. The good thing about these motors is that they provide good accuracy and durability, making it a worthy investment.

As for the grind chamber, you will note that there is no much difference between the two. The InSinkErator comes with a Multi Grind design. This includes having a specialized grind ring, extra impellers, and a post-cutting disc. The result is that you end up with finest ground food waste better than expensive models.

When it comes to the noise level, for many they might find the InSinkErator garbage disposals to be quite loud. Well, most of disposals are loud because of the activity they have to do. Sound proofing costs a lot of money that might make some models to be a lot more expensive.
