How to Choose the Quietest Garbage Disposal Unit
To identify the quietest disposal, you need to check out the following in any new disposal unit.
Sound Masking System
Sound masking in a disposal is a unique feature that helps to make a top-performing disposal quiet. It aims to reduce noise during grinding by covering the motor with sound-absorbing material.
Material of Construction
Before buying any disposal, you need to check the kind of materials used in its manufacture. After all, acquiring a garbage disposal unit is a long-term investment. You wouldn’t want to buy one and only to replace it after a few months of use.
Most brands use a thick layer of Polymer to mask the chrome-plated steel grinding chamber. The thickened layer of polymers helps to dampen down the sound, thus making the unit quiet when operational.
Decibel Levels
A unit’s noise level is also a crucial factor that you need to consider in order to pick the quietest disposal unit. Although the standard disposal systems generate substantial noise, most people opt for a quiet one. The best garbage disposal, therefore, should not produce a lot of noise. Their noise levels should be below 70 decibels.
Grinding Ability
The grinding ability of garbage disposals varies depending on their make and model. Not all models have the same design and specifications. Some are only ideal for single-person households while others can grind garbage produced by large families of between 8 and 12 individuals.
What are the Benefits of a Quiet Garbage Disposal?
Below are the different benefits of installing a quiet garbage disposal in your kitchen.
Comfortable Cleaning Routine
A noisy garbage disposal system can be inconveniencing to use in many households. With a quiet garbage disposal, however, you can use it even when a child is sleeping or when an elderly loved one who is sensitive to noise is visiting or living in the home. With it, you won’t disturb or inconvenience anyone.
Environment-friendliness
Food leftovers often end up in landfills to decompose, thus contributing to the increasing levels of methane emissions into the atmosphere. Having the quietest disposal, however, means that you can help reduce these emissions. Moreover, having the quietest garbage disposal unit helps curb noise pollution.
Clean and Tidy Kitchen
When your kitchen has too much food waste lying about and the garbage can is overflowing, the kitchen and the home as a whole could be contaminated by bacteria and germs. If you have a quiet garbage disposal unit, however, you can eliminate food wastes before they start building up and rotting in your kitchen vicinity.
Things to Look for in a Quiet Garbage Disposal Unit
Construction Components
The best quiet garbage disposal should come with internal stainless steel grinding components. This kind of construction allows the garbage disposal to grind even the toughest food scraps efficiently and with ease, especially when coupled with a motor that has a higher power rating. Besides making the work easier, stainless steel components also do not rust or corrode, thus enhancing the unit’s durability.
Power
The rate of power is in terms of horsepower. The horsepower units indicate how powerful the disposal’s grinding motor is. Most of the quietest garbage disposals have low horsepower ratings of 1, 3/4HP, 1/2HP, or 1/4 HP. Note that the lower the horsepower, the slower the grinding process and vice versa. Powerful motors are good at thwarting jamming, but more power isn’t always the best.
Ease of Installation
The best quiet garbage disposal unit should also have the easiest installation process. You won’t need to hire a technician to have your new disposal fixed. Some brands offer a twist-and-lock installation process while others fit their units with three bolts for ease of installation. The best disposal unit should also have a power cord for easy plugging into electric outlets near the wall.
