Did you know that dirty humidifiers can make you sick? According to the Mayo Clinic, "Dirty humidifiers can breed mold or bacteria. If you have allergies or asthma, talk to your doctor before using a humidifier." Just like forgetting to clean the fridge or change our bed sheets, many of us let our humidifiers run longer than we should without cleaning them. When we do this, our helpful air-quality device can turn into a place where harmful germs grow. Let's look at the simple steps to keep our humidifiers working safely and well, so the air we breathe stays clean and fresh.

Things to Do When Cleaning a Humidifier
Maintaining a clean humidifier is essential for guaranteeing healthy air quality and peak performance of your device.
Regular cleaning prevents the buildup of harmful bacteria, mold, and mineral deposits that can affect both the unit's efficiency and the air you breathe.
A proper cleaning routine not only extends the life of your humidifier but also guarantees it continues to provide the intended benefits of adding moisture to your indoor environment.
- Unplug and disassemble – Remove all detachable parts and empty any remaining water from the tank and base.
- Prepare cleaning solution – Mix equal parts distilled white vinegar and water in a container.
- Soak components – Place removable parts in the vinegar solution for 30 minutes to dissolve mineral deposits.
- Scrub surfaces – Use a soft brush to clean hard-to-reach areas and remove stubborn buildup.
- Clean the filter – Rinse the filter in cold water only, avoiding harsh chemicals or hot water.
- Rinse thoroughly – Wash all parts with clean water to remove vinegar residue.
- Air dry components – Allow all parts to dry completely before reassembling.

- Test operation – Fill with clean water and run briefly to guarantee proper function.
Things to Avoid When Cleaning a Humidifier
Proper maintenance of your humidifier is essential for ensuring clean, healthy air in your home, but certain cleaning practices can damage the device or create health hazards.
Using the wrong cleaning methods or materials can't only compromise the humidifier's functionality but also potentially expose you to harmful substances or create conditions that promote microbial growth.
- Bleach and harsh chemicals – These substances can corrode plastic parts and create dangerous fumes when combined with other cleaning agents like vinegar.
- Water submersion of electronics – Getting water into electrical components will short-circuit and permanently damage the humidifier's operating system.
- Abrasive cleaning tools – Wire brushes and rough scrubbers can create scratches that become breeding grounds for bacteria and mold.
- Tap water for filling – Contains minerals that leave scale deposits and create difficult-to-remove buildup inside the unit.
- Irregular maintenance – Skipping routine cleaning allows harmful microorganisms to thrive and potentially get dispersed into your breathing air.
- Mixing cleaning solutions – Combining different cleaners, especially vinegar and bleach, can create toxic gases and dangerous chemical reactions.
