Product review (1 stars): DONT BUY!!!
This filter was full of mold within a month of using. I live in New Mexico, we have no humidity - we have a terribly dry winter season. The filter that came with the humidifier I bought lasted the entire winter last year. Do not buy this one! And if you do, check the filter to make sure you are not pumping black mold into the air. I used this in my toddlers bedroom. :(
