How Quiet is ‘Quiet’ When it Comes to These Humidifiers?

When buying a humidifier, one needs to make sure it does not have that annoying whizzing sound. A humidifier is a machine and, as such, it is meant to make some noise. So, you have to choose the one that makes the least noise.

A standard cool mist humidifier makes the sound somewhat similar to running water as the machine’s fan whizzes and throws out cool air.

There are ultrasonic humidifiers on the market that make next to no sound. These use high-frequency sound waves that vibrate a metal diaphragm, creating a fine mist at ultrasonic frequencies. The ultrasonic humidifier has a higher frequency than sound, rendering it almost inaudible.

How We Chose These Humidifiers

There are many aspects to look into when purchasing a humidifier. Firstly, one needs to ask and answer the main question; do they actually need a humidifier? If the atmosphere where you live has an overall dry impact, then you need this to combat the above-mentioned problems.


Our bodies need humidity, and if it’s not provided, they suffer. Not only do our bodies react to dryness, but it also has an impact on the flooring and wallpaper in our homes, leaving them cracked and ruined.

Location, Location, Location

Next, you need to decide the place, size, style, and space you would use for a humidifier. Is it needed mostly in one room or the whole house? Will owning a humidifier make your living space more compact? Can it be accommodated on a table or does it need to be mounted?

Venta LW45


There are different types of humidifiers ranging from the cool mist, warm mist or ultrasonic humidifiers. It solely depends on the person’s priorities and where they live.


The last thing is maintenance. You need to have an acceptable difference in purchasing cost and maintenance cost. Moreover, how many times the humidifier needs to have maintenance is another key concern. This can include purchasing filters and cleaning frequency.

Keeping all these factors in mind, we’ve collected some of the best quietest humidifiers and reviewed them for your convenience.

The Venta Airwasher 2-in-1 is here to stay. This comes in three sizes being 200, 400, and 800 square feet. The Vent LW 45 humidifies the room and simultaneously purifies it too. The dry air entering goes through the Airwasher unit, passing over the moistened rotating disc stacks. It then falls down into the basin. Following this, only the clean air evaporates, leaving the impurities behind.

Due to the evaporation method, over humidification is not possible. This is because the humidifier doesn’t push the air out, but lets it evaporate. Due to this cold evaporation technology, the Venta LW 45 does not require any filter changes. This simple design is also environment-friendly, as resources aren’t wasted on the changing of filters.

The Venta LW45 comes in a black color. It is capable of purifying pollutants down to 0.3 microns in size. Other humidifiers produce a white dust, which is quite common as they heat the water, causing the mineral content to separate.

This humidifier is the safest, easiest option to keep your humidity levels in check.

This product is not like the old school humidifiers that caused condensation and wood warping. It keeps you and your surroundings in check.

If you are running on a budget, the Honeywell HCM 350W might just be right for you. It is easy, functional, and is not heavy on the pocket. This cool mist humidifier throws cool mist into your surrounding air without causing much hassle. It uses a gallon of water and utilizes it over a period of 24 hours. This is the perfect humidifier for your bedroom or any medium-sized room. The UV technology installed into the Honeywell kills off 99.9% of bacteria in the water.

It doesn’t thrust the water out a nozzle but uses the advanced evaporative technology. The moisture is blown off of the wicking filter. This way, the evaporation is made quicker. The Honeywell does not over-humidify your room due to the advanced evaporative technology. When the air can no longer retain moisture, the evaporation gradient will hinder over-humidification.

At an optimal 40 to 60% of humid air, the Honeywell battles nasal congestion, dry skin, and makes sleeping and breathing easier. This Humidifier aids well with babies, especially in the spring season when pollen and certain allergens are on a roll.

The Honeywell works on a four-step plan. The water flows through the UV path, ridding it of 99.9% bacteria. It then flows into the base, where the wicking filter absorbs water. Due to the difference in the concentration gradient, the water from the wicking filter evaporates towards the surroundings, where the water vapor gradient is low.

Bottom Line

The Honeywell humidifier is handy and affordable. It uses evaporation technology, making sure white dust doesn’t accumulate.  It is easy to install, use, and clean. The filter and tank have a long life and need low maintenance. Overall, it is ideal for small rooms.
