Pick up a UV sterilizer to help keep your water clean! This UV light certainly isn't needed to make a DIY humidifier but will help extend intervals between cleanings.
How to use a UV sterilizer: Just plug it in and drop it in your water reservoir... it's that easy! You don't need to run it 24/7 either! Use a timer to run it for about 3 hours per day depending on your environment. If you don't get the needed effect, increase the run time until you have consistently clean water.
