If you own a home humidifier, it is important that you know how to clean a wick filter. If neglected, this filter can become very dirty very quickly, resulting in unclean air being emitted by the machine. So, to keep your wick filter clean and to ensure that your humidifier emits fresh air, carry out the following process at least once a week.

Step 1 - Take Apart Your Humidifier

Disassembling your home humidifier is the first step you have to take to get to the wick filter. When performing this step, make sure to have your humidifier's owner's manual on hand, as the disassembly instructions will vary between brands and models. If you can't find the device's manual, you should be able to find detailed instructions for disassembly on the Internet by typing your brand and model into your preferred search engine. Regardless of the type you own, taking it apart should be fairly simple and will not require the use of any tools.

Start by turning off your humidifier and unplugging it from its power source, after which you will need to remove the device's tank. This should give you easy access to the wick filter, which, in most cases, you will be able to carefully jostle out of place with your hands. Once your wick filter has been safely removed, you're ready to move on.

Step 2 - Rinse Your Wick Filter

Next, you need to give the filter a thorough rinse with water. Holding the filter in one hand, proceed to run a steady stream from a sink or bathtub faucet over it, paying special attention to any noticeably dirt-laden areas. If one is available, a detachable shower head can also be used to perform the rinsing. As the filter undergoes its rinse, use a toothbrush or soft-bristled scrub brush to get rid of any easily-dislodged bits of filth. Once your wick filter has been vigorously rinsed and a fair amount of dirt has been removed, you may proceed.

Step 3 - Soak Your Filter

The third and, arguably, easiest step in cleaning a wick filter involves soaking the filter in a mixture of water and white wine vinegar. Combine the ingredients for the aforementioned mixture in a pot or bowl, place your wick filter inside, and allow it to soak for 45 minutes to a full hour. After the filter has soaked, you will need to once again use a scrub brush or toothbrush to remove any remaining bits of filth. Complete this step by giving your freshly cleaned filter another water rinse followed by a thorough towel-dry. If any portion of your wick filter still appears to be dirty, the filter will need to be replaced.

In addition to the wick filter, it is strongly recommended that you clean the other parts that make up your home humidifier at least once every week. Furthermore, take care to replace your wick filter as often as specified in your humidifier's owner's manual.
