Product review (4 stars): Must replace it annually as it gets dirty and crusts up once it gets dry
Hard to find filter for my humidifier since Holmes made it under the Sears brand name. Luckily I was able to find the Holmes name associated with my Sears model from online research!

The price is relatively expensive and it will get More expensive and hard to find in the upcoming years since the model is No longer made. May have to eventually replace the humidifier with a NON-FILTER model.

Until then, this filter is needed and it works! Must replace it annually as it gets dirty and crusts up once it gets dry.
