Number of revolutions

The motor shaft's nominal speed is a crucial factor in the operation of the waste disposal unit, as it determines the speed of processing. Models with higher nominal speeds can process waste faster than those with lower speeds, provided that their power and other features are equal. However, high speed can also lead to increased noise levels and a reduced ability to handle solid particles.

Chamber capacity

The working volume of the waste disposal unit's chamber. This parameter determines how much waste can be placed in the device in one load. For everyday use in an average family, a volume of up to 1 liter or even less (about 600 – 700 ml) is considered quite sufficient, however, there are also more capacious models.

Chamber material

The material from which the working chamber of the waste disposal unit is made.

— Plastic. The working chamber of waste disposal units can be made of plastic or metal. Plastic chambers are affordable, easy to process, corrosion-resistant, and create less noise compared to metal chambers. However, plastic is generally weaker and less reliable than metal, though still adequate for typical use cases. Plastic chambers are typically found in entry-level and mid-level models.

Metal. Metal chambers have the advantage of high strength, making them suitable for use in powerful waste disposal units intended for tough working conditions. However, metal chambers tend to be more expensive and produce more noise during operation.

Overload protection

Protective system is installed in waste disposal units to prevent damage when the load on the tool becomes critical, such as when hard or large waste gets stuck. Typically, the protection system shuts off the power to the motor, allowing the user to address the issue and resume work. However, in more powerful models, the system may boost the motor's power for a brief period as an initial measure. If the problem persists, the unit will shut down to prevent damage.

Noise level

The average noise level generated by the device during normal operation.

A waste disposal unit that produces less noise is more convenient to use, especially in situations where loud noises are unwanted, such as having a baby in the house or working in the kitchen late at night. However, it's important to consider that a powerful motor and a metal chamber may increase the noise level despite having advanced features.

Decibel values are used to indicate the noise level of waste disposal units, and it is a non-linear quantity. The easiest way to assess the noise is by comparing values in tables. Below is a simple table of noise values that are relevant for modern devices:

— 25 – 26 dB — the volume of a person's whisper at a distance of about 1 m, the noise level of the quietest models;
— 30 dB — the noise level that is acceptable for residential premises at night according to health regulations is equivalent to a soft whisper or a constant background noise at its maximum volume.;
— 35 dB — talking in an undertone;
— 40 dB — normal speech, the maximum volume of a constant background noise, permissible in living quarters during the day;
— 50 dB — conversation in slightly raised tones;
— 60 dB — loud conversation;
— 70 dB — The noise level of several loud conversations occurring within a range of approximately 1 m from each other;
— 73 – 75 dB — scream or loud laughter; the maximum noise level enco...untered in waste disposal units.
