Replacing a humidifier filter is actually a very easy process. Most modern models are designed with the user in mind and thus try to make the disassembly and reassembly of the unit as simple as possible. While the unit is being opened up for filter changing, it is also a good time to do some basic cleaning.
The frequency of change depends on how much the unit is used. The filter is ready for a change whenever there is visible build up of dust and pollutants. If there is nothing visible the filter still should be changed at least once a year to rid of invisible mold spores or bacteria that could be lurking in the filter.
Before beginning the disassembly, ensure that the power cord is unplugged. Once the power is disconnected from the source begin by removing and emptying the water reservoir. Refill the tank with fresh cold water and disinfect with a tablespoon of bleach to kill any mold or bacteria that might have developed. Allow the bleach-water solution to sit for 20 minutes.
In the meantime, proceed to the next step and remove the housing cover of the motor. This is usually a large part of the top of the unit. Use this opportunity to clean any dust that might have accumulated. This is the most disassembling that can be done without voiding the manufacturer warranty.
Now lift the filter out of the unit. Some models have filters that can be cleaned and reused. Since most replacement filters are economical, it is usually a good idea to simply use a new filter as it is the cleanest way to go. If you do choose to wash and reuse the filter be sure not to squeeze or wring it dry to avoid tearing the filter.
Putting the unit back together is pretty straight forward. Everything goes back the way it opened up. The base of the unit can be cleaned with a cup of white vinegar. Just let it sit for about 20 minutes, then use the bleach and water mix from the water tank to disinfect. Then rinse everything to rid of the cleaning chemicals.
Changing the humidifier filter regularly is the best of ensuring optimal results when the unit is used. Those who wish to avoid the maintenance of changing filters can opt for a filter free humidifier.
