All individuals need water to live, but did you know that your home also benefits from the right level of moisture? Water droplets in the air are needed to maintain a proper balance of moisture or humidity in the atmosphere of your home. This proper balance will be just enough humidity to dampen the air you are breathing, allow for smoother skin, a healthy throat and mucous membranes properly moist.

The number of water droplets in the air of your home should not be high to cause respiratory issues or irritate the skin by creating a dewy layer on the skin. Structural damage can also occur throughout the residence when the moisture levels are out of sorts. So it’s important to have a humidifier only if you need one and to make sure to keep humidifier filter clean.

How it Works

A humidifier is a marvelous invention that controls the amount of humidity in your home by adding microscopic water droplets when needed and can put out of operation when they are not. Almost any style of humidifier comes complete with a filter, whether it is a portable (single-room) device or a complex device installed directly into your home’s central air system.

This filter removes all sorts of things from the water droplets before they are released into the air; from bacteria to allergens to common household germs. If the filter of your humidifier is not properly maintained, not only are you sending all of these into the air you breathe but other bacteria can develop and be added to the mix; such as mold.

Make sure whatever cleaning solution you chose has an ingredient that removes stains, kills germs and bacteria, and isn’t strongly scented which can cause headaches

When you take it upon yourself to bypass a professional routine cleaning and decide to instead clean your humidifier filter at home, it is important to mention how not only important it is but how essential it is to check the instruction manual that would have been provided with your device for any specific instructions. This could be instructions from the length of the soaking time of the filter or what sort of solutions you should or should not introduce to your machine.

There may also be steps to follow to ensure the warranty of your device is intact.

Step 1

Fill up your sink with hot water and add some sort of cleaning solution or extra-strength soap; either homemade or store bought.

Step 2

Remove the filter from the humidifier and put it directly into the hot water with the preferred cleaning compound and allow the filter to fully submerge and soak for at least 15 minutes.

Step 3

Clean all the internal components that surround the filter, using a homemade cleaning solution or a store-bought solution made especially for humidifiers. These internal components are everything from the reservoir of water to the fan blades that break up the water into microscopic droplets.

Step 4

Refill the reservoir with distilled water and add a teaspoon of baking soda to remove stains from the inside. This tip also has the added benefit of the humidifier releasing clean-smelling water droplets into the air. Check to see if your humidifier has the option for an essential oils diffuser or check with the manufacturer to determine if adding essential oils will damage the device.

Step 5

Clean the entire base beneath the filter using a homemade solution or extra-strength soap and a scouring pad. Dampen the pad and add a dollop of cleaning solution that will remove the bacteria, germs, and mold that can live on this base and are unseen to the naked eye.

Step 6

After both the internal parts and the filters’ base are sanitized; it is time to clean the filter itself. Take the submerged filter out of the soapy water to determine if elbow grease and scrubbing is needed.

– If there are mineral deposits visible throughout the filter, a solution of vinegar, bleach, and water would be the easiest and most efficient way to remove these.

– If there is mold on the filter, you can try to clean it but it is highly recommended that you replace the entire filter due to health-related reasons.

Step 7

Once the filter is scrubbed clean and is free from visible spots or debris, rinse the filter in the pure cleaning solution for a final germ-check and to remove any additional particles that have been dislodged from the filter.

Step 8

Rinse the filter under pure hot water and allow to completely dry; either on a clean dish towel or placed on a drying rack normally used for household dishes.

Step 9

Check the base components to make sure that they are completely dry before replacing the filter inside the humidifier as damp or dark conditions can be breeding grounds for harmful germs or bacteria.

Step 10

Replace the humidifier covering and remove it from near the water source before re-plugging the power cord into the electrical socket.

Step 11

Proceed to use your humidifier as normal!

If the manufacturer of your humidifier requests that a replacement filter is used at certain intervals, then it is recommended that you do not attempt to clean your filter on your own as this can void any manufacturer warranty that exists on your device.

Check the humidifier filter on a regular basis, such as bi-weekly or even weekly depending on the amount of time the device is in use.

Conclusion

Now that you not only know why it is important to clean your humidifier filter, you know how easy it can be to clean your humidifier filter right at home. Unless it is directly specified by your appliances warranty, you shouldn’t need to bring your humidifier to a local retailer for maintenance.

Central humidifiers that are installed directly into your home’s central air system are slightly more complex and unless the filter is easily accessible, a technician may be required to come into your home and remove the filter for cleaning.

Humidifiers are wonderful inventions that dampen the air of your home, allowing for all ages to breathe deeply and normally. It prevents fire hazards and the cracking or splitting of the wooden support beams found within your walls. But how good is this device if the filter isn’t clean and all you are doing is breathing bacteria or germs? Not very good! So with a little bit of time and elbow grease; you and your family could be breathing cleaner!
