Product review (5 stars): Be careful and order the correct filter
Perfect fit for my humidifier. Be careful about the Lowes and Home Depot replacements. The length isn't exactly the right length. Always buy the Essick replacement. Lowes offered to order an off brand replacement but it was $24 and would need some trimming. (Plus up to a week to receive). Amazon had a fair price and it was delivered in 2 days for free. In my opinion a good buy.
