Benefits of Quiet Waste Disposals

There are various benefits of opting for quiet waste disposal systems:


Food waste that ends up in landfills decomposes and contributes to the increasing methane emissions in the atmosphere. By using an ultra-quiet garbage disposal, we can effectively reduce greenhouse gas emissions, and cut down noise pollution.

Clean and Tidy Kitchen

A kitchen with a lot of leftovers lying around, and a full garbage can, is a haven for bacteria and germs which can rapidly spread across your house. By using a quiet garbage disposal, you can get rid of leftovers before they start rotting and smelling.

Comfortable Cleaning Routine

Having a noisy garbage system can cause inconvenience for a household. Be it a child sleeping peacefully, or an elderly house member who is sensitive to loud noises etc, a quiet garbage disposal system will not disturb anyone.

Choosing the Best Quiet Garbage Disposal

Sound Masking System

The sound masking system is a unique feature that sets quiet garbage disposals apart from conventional disposal systems. These systems are designed to reduce noise during the crushing debris process, by encasing the motor with sound-absorbing material.

Decibel Levels

Noise level is an essential factor when choosing the best quiet garbage disposal system. Standard garbage disposal systems can create considerable noise, which is why people want to opt for quiet garbage disposals. The best garbage disposals do not produce a lot of noise. Their noise levels are under 70 decibels, similar to the noise emitted by vacuum cleaners.

Material Construction

Another important consideration when choosing a garbage disposal system is the durability of the machine.

Some questions you should ask before purchasing a disposal system include;

What material is it made of? 

Will it prove to be durable?

Typically, leading garbage disposals have a sturdy stainless-steel construction for added strength and durability.

Best Quiet Garbage Disposal

Waste Volume & Grinding Capability

The waste volume and grinding capability of garbage disposals differ, depending on the make and model. For example, some models are specially designed for use in a single person household, while others are ideal for bigger homes with up to 9 people.

Smaller units are also designed for soft and small food items, while high-end products can easily break down larger chunks of garbage.

Motor Capacity (Horsepower)

Lower end models can have ½ horsepower motors, while more advanced systems go up to 1 ¼ HP. The power of the engine directly impacts the disposal’s grinding capability, and more powerful systems can easily tackle hard items, such as chicken or fish bones.

Speed (RPM)

RPM stands for “revolutions per minute,” or the number of times that the cutting blade in a disposal unit spins in a minute. While basic models average around 1750 RPM, higher-end products can go as fast as 2500+ RPM.

Feed Type

The feed type is another important feature of ultra-quiet garbage disposals. You need to consider whether you want to purchase a model that allows you to ‘feed’ it whenever you wish, or if you would like to dispose of your garbage in batches.

Additional Perks

Users should also research the type of power connection a garbage disposal unit supports. There are various connection kits and adaptors available in the market, which can be plugged into any outlets. The safety codes that apply to your residence play an essential part in deciding where, and what type of switches should be installed with the disposal unit.

Ease of Installation

Majority of the new garbage disposals come with all the necessary equipment for connecting the unit to the sink.

However, if there is no nearby outlet than one will need to be hardwired, which might be a difficult task depending upon your kitchen’s layout.

If you're unsure, many of the brand's offer technical support via phone call. You can also call a plumber to do the job. 

Best Under Sink Garbage Disposal


Garbage disposals feature an extended warranty; most units come with a 5+ year warranty. Built with durable material, these machines can last for a long time – provided that users clean it regularly to ensure that it does not clog up.

Hence, should your disposal system malfunction due to a material defect or a mechanical flaw, you can have the unit replaced quickly.

  • Batch Feed:
    This type of garbage disposal pulverizes food in batches. To start it, one needs to cover the disposal top.
  • Continuous Feed:
    Continuous garbage disposals keep running endlessly, from the moment you switch them on, to the moment they are turned off.
