How Did We Test Listed Quiet Humidifiers?

The selection of a quiet humidifier can’t be an easy task. To make things easy for you, we spend several hours and find the top eight quietest humidifiers available on the market.

If you are not happy with the choices above, you can check a small guide to select the best product for you.

It proves helpful for you to understand the reason for each unit in the above list.

It will prove helpful for you to understand the best qualities of the quietest humidifiers in the market.

See our primary testing stages:

  • Stage 1 – In the first step, we pay attention to the packaging, assembly, and installation of a humidifier. We gauge how expedient a humidifier is for everyone, along with its operation and set up. Moreover, we evaluate its cleaning method because you have to empty a tank daily to avoid the growth of bacteria. Before moving to the second step, we do some sound tests.
  • Stage 2 – We test the efficiency of a humidifier in this stage. We set a timer, check the capacity of its water tank, change the direction of mist, and thoroughly test every feature. Testers compute the energy every model needs to emit one gallon of water in the form of mist.
  • Stage 3 – In this stage, we test the moisture output of each humidifier with the use of hard water. To conduct this test, we dissolve minerals in hard water. These minerals can clog a humidifier and decrease its moisture output. Moreover, we test their noise on high settings and try to see their efficiency in the long run.


Is there any ideal moisture level to maintain?

Yes, the ideal level may vary from 45% to 50%. Humidity from this limit can create a perfect breeding ground for bacteria, dust mites, mold, and other pests. If moisture is lower than 30%, it can increase the spread of viruses of flu and cold.

What is the best size for a humidifier?

To determine the right size of a humidifier, you have to check the square footage of your room you want to moisten.

Almost every humidifier manufacturer offers a coverage range in square foot. You can find this information in the specification of a product.

Remember, in-duct, and console humidifiers can cover large areas.

Is it necessary to check the capacity of a humidifier?

Yes, it will help you to choose the best humidifier. The capacity of a humidifier means the maximum output of moisture a machine produce in 24 hours.

Remember, capacity can be different because of the tank size of a humidifier. The tank will show the quantity of water a reservoir can hold.

How do users add liquid to a humidifier?

The water filling mechanism may vary in each humidifier. Console or portable tabletop humidifiers may feature one or even more reservoirs. 

If you want to fill a humidifier, open the reservoir of water to pour in the clean liquid.

Sometimes, you can carry a humidifier to the water sink for refilling. A few models come with top-fill reservoirs to fill with a hose or a pitcher.

In a furnace humidifier, you may not get water reservoirs. You can hook them directly to the water supply of your home.

Can I fill hard water in a humidifier?

Yes, it is possible to use hard water in a humidifier. If you are living in an area with hard water, buy a humidifier that has a mineral cartridge.

Moreover, clean your machine more frequently to avoid possible issues.
