Hello! Thank you for reaching out to us. We recommend replacing the wicks every 30-60 days. Your results will depend on your water and how well you maintain your humidifier. If you have an excessive amount of mineral build up in the wick due to your water, you can try placing some white distilled vinegar in your water – this will help break down some of those minerals. One teaspoon of vinegar per gallon of water is the recommended application. Feel free to call us at 1-800-547-3888 if you’d like more information on caring for your wick. Thanks! -Melissa, AIRCARE
