Is It Easy To Clean A Dyson Humidifier?

The complicated periodic maintenance of the previous version of the Dyson humidifier was a huge drawback and made the competitors’ products more appealing. Thanks to the tiny opening and bizarre internal component arrangement!

As a direct response to the loophole, Dyson made the new version almost effortless to clean! It comes with an easy-to-remove water tank, filter, and evaporator. Also, it comes with packets of citric acid powder. All you need to do is soak the parts in the solution, rinse, dry off, and reassemble!

The monthly deep-cleaning saves you time and effort. A Dyson humidifier features a smart self-cleaning button that does all the work in one go.

What Are The Best Solutions To Clean A Dyson Humidifier?

Cold water alone isn’t effective at removing stubborn dirt build-ups on the Dyson purifier. With the following solutions, you can create a homemade cleaner: 

natural cleaners, baking soda, vinegar, and lemons on a table

Distilled White Vinegar

Prepare distilled white vinegar by measuring two cups of this solution. It can wipe out residue build-up on the base tank in one swish. Furthermore, it fights off spores. 

Citric Acid

Citric acid destroys the cell membrane of bacteria, inhibiting their rapid increase. Mix two tablespoons of citric acid powder with cold water, and you're all set!


Bleach is a strong cleaning agent that loosens and discards mineral deposits without a trace. Just add 1-teaspoon of chlorine bleach per gallon of water.

Baking Soda

Baking soda consists of an alkali that, when combined with water, releases carbon dioxide that washes off slime and scaling on the reservoir.

Fill the water tank halfway with cold water. Add your preferred solution, put the cap back on, then give it a shake.

Re-open the cap and place the evaporator in the water tank. Fill the water to the 'Max' level, replace the cap, then let it sit for 15 to 20 minutes. 

4. Drain And Rinse The Water Tank And Evaporator

Drain the water from the tank. Take out, then rinse both parts under running water. Dry them with a lint-free cloth to remove any residue. Let the evaporator sit until it’s completely dry. While waiting, fill the water tank with cold water to the 'Max' demarcation level, then close the cap firmly.  

5. Reassemble

Once dried up, replace the evaporator in the machine. Close the inner cover. Slide the water tank back in. Make sure it clicks in place. Replace the outer cover.

Can I Wash Dyson Humidifier Filter?

A Dyson humidifier may come with one or multiple filters, depending on the model. To maximize their efficiency, they also need to be cleaned periodically. See instructions below: 

  • Rinse and gently squeeze it under cold water. Avoid using any type of detergent. Use only plain water.
  • Let it dry for 24 hours. Avoid drying it with any heating tools as that may damage it.
  • Once dry, put it back in. 

How Often To Replace Dyson Humidifier Filter?

Dyson highly recommends a filter replacement every 12 months. That’s the typical lifespan of any filter. A clogged filter causes an unpleasant odor in the house and also makes the humidifier work harder, shortening its life span. A Dyson filter costs anywhere between $70 to $80.

Can Mold Grow In A Dyson Humidifier?

How To Prevent Mold In Your Dyson Humidifier?

Tea Tree Oil

This is a natural disinfectant that contains anti-viral, anti-fungal, and antibacterial properties. It prevents mold and other pollutants.

White Dust In A Dyson Humifidier: Should You Be Concerned About It?

White dust is the by-product of mineral deposits that gets mixed up in the mist. They attach to your furniture, clothes, and home appliances. Dyson recommends the use of distilled water to prevent this. However, that can be expensive as the water must be replaced daily. 

Ways To Maintain Your Humidifier 

By following these tips to maximize the efficiency and life expectancy of the Dyson humidifier. 

Soften The Water 

This is the solution to the problem above. It’s hard water that often contains mineral deposits such as calcium and magnesium. They clog the filter, hence, it works harder. The result? Poor performance and shorter life expectancy. 

But you don’t necessarily have to use distilled water, try these simple and relatively cheap solutions instead:  

  • Boil the hard water. As it cools, the mineral deposits dissolve. Pour in the water tank. 
  • Use a water softener. They are made to eliminate chemicals that make water hard.  
  • Use demineralization cartridge. Place it at the bottom of the tank. They filter small and large particles so the mist comes out without impurities.

Change The Water Every day

Don't let the water sit in the tank for more than two or three days. In less than 72 hours, it can harbor spores and microorganisms. If you will be out of the house for a few days, drain the water from the tank first.

Don’t Overstress Your Humidifier And Set It At The Right Level

Run your humidifier only when the indoor air quality is bad. Leaving it on 24 hours can damage the filter. Fortunately, a Dyson humidifier has an auto-mode feature that only activates the device when there are pollutants, smoke, and pathogens present in the air. In other words, it only turns on when necessary.

Remember to set the right humidity level, too. Between 30% to 50% is the recommended setting during the winter, while it’s 50% when the humidity level is high. Setting at 60% can already make your home uncomfortable and susceptible to mold. 

Hydrate Your Humidifier Filter 

If you have a top-filled humidifier, the filter stays in a standing position. This leaves some parts of it dried out. If neglected, it can lead to wear and untimely replacement. Make it a habit to turn the filter over when you change the water to keep the top portion hydrated.

Can You Reuse Humidifier Water?

Making the most of water conserves resources and the ecosystem. You can reuse the humidifier water on your indoor and outdoor plants but not on the edible ones. This is due to the risks of microorganisms and aluminum and copper contamination.
