Those who live in developed countries with unlimited access to clean water may feel that there is no need to care for their humidifier since the water coming in is pretty clean. Results from studies conducted have revealed that water although clean contains minerals that are capable of clogging up the humidifier over time, thus affecting its performance level.

Basically, disinfecting or cleaning your humidifier is of utmost importance if you do not want your loved ones to suffer ailments of any sort. 

How To Disinfect A Humidifier 

To prevent bacteria or mold build-up, it is important that you regularly disinfect or clean your humidifier. To do this, you shouldn’t be needing a lot of cleaning materials. Some of the essential materials you'd be needing include: 

  • Gloves and goggles 
  • White vinegar 
  • Soft bristle brush 
  • Clean towels 
  • Plenty of water 
  • Bleach or hydrogen peroxide 

While most of the humidifiers are constructed differently from the others, most of them come with an operating base and a water tank. Before cleaning or disinfecting your humidifier, it is important that you take a moment to go through the users' manual before disassembling any of the parts. 

To clean your humidifier, there are a couple of steps you need to take. By simply following these straightforward and easy to carry out steps, you get the most from your humidifier and also improve the quality of air in your home. 

Step 1 

Unplug your humidifier from the wall and disassemble it completely. Find the water tank then remove and empty it. Depending on the model of your humidifier, you need to either unlock or unlatch other parts and keep them separate for easy identification. 

If your model comes with an air filter, it is equally important that you remove it. To clean the air filter, you simply need running water. Once that is done, you leave it to dry. 

Step 2 

The next thing is pour a substantial amount of white vinegar into the operating base of the humidifier to the point that it fills all of the areas that water comes in contact with. If there are smaller detachable parts, soak them in a large container with white vinegar. Leave for 30 minutes or thereabout. The reason for this is so that the mold or bacteria build-up is broken down. 

Once that is done, you need to make use of your soft bristle brush to clear off any residue that may have stuck to some of the parts. Smaller brushes have proven to be ideal for this. 

Step 3 

To disinfect your water tank, you need to add 1 teaspoon of bleach or hydrogen peroxide to 1 gallon of water. Since you need to leave this to disinfect for 30 minutes as well, it is best that you do this at the same time as Step 2. 

Step 4 

Once the 30 minutes wait period is over, use running water to wash the base, water tank, and the other components or parts of the humidifier. You are advised to shake these parts to ensure that all clogged up moisture is dislodged. While it may take time before the smell begins to dissipate from the parts, be rest assured that it will happen. 

Lay all of the cleaned-up parts on your clean towel to dry. This helps to remove any foul smell. 

Step 5 

Once you have allowed all parts to dry out completely, it is time to assemble them. You need to fill your tank with clean water, distilled water preferably. If there's a need to, you may have to replace the air filter. 

If there are additional components or parts not mentioned, you are advised to clean them the same way other parts were cleaned.
