Filters were very well packaged and delivered. The quality of the filter appears to be very good as well - I was glad to see it absorb water all the way to the top which would speed up evaporation. Overall good product. Time will tell howit does over time!

These filters seem to work well and were less expensive than options in our local hardware store.

Good price, quick delivery, fits correctly, wicks water well

This is a product I have used for many years and is the only one to buy.

Works as advertised

Worked great for about 7 days and then filter was hard and stopped wicking up water. I have my humidity level set on max on my humidifier but I would have expected a lot more than 7 days out of one filter. I won't but these again. Maybe if they were half the price. Junk!

I have very hard water with a great deal of calcium in it ( no softer )These work well during the winter dry season and in my experience, 1 filter lasts 1 season.

These seem to clog up and stop working after a week or two.

It’s exactly what we needed. These filters are for our humidifier.

Very much comparable to the brand name product.

Good value for the price. They don't last as long as the holmes brand.

I actually was reordering the last week and canceled! Very disappointed with the life span. Last filter laster a week. Stopped wicking to about 1/2 way up. Learned the hard way to never let the water in your humidifier go low! Keep it clean. But this last filter did it all on it’s own. I know proper care of my humidifier. These filters i guess are just low end products. Not good
