Walgreens Cool Moisture Humidifier Filter W889-WGN, 1 Each

I wasn't sure about the size, because it came in a flat package. But it fit perfectly.

Fit my Walgreens humidifier just right. Double check the product number before ordering, as I've heard they are very specific. Got 2.

After seeing many new stories about the bacteria building up in humidifiers and the filters, I thought it was necessary to replace mine. So very easy as soon as I located my unit number. Correct filter, works perfectly

I change these annually. I mostly use the humidifier in the winter to moisten the hot air and to help prevent dry throat problems. I sometimes place a cotton ball with eucalyptus oil on top to help with breast issues.

Need this humidifier filter for my humidifier and works great. Thanks for making this product as will buy again when need arises

A bit high price for one filter

The filter is great. However it came in plastic envelope and was mashed.

These are tricky trying to find and now I have my new source.
