Simple to use
It is great to be able to bulk order these and replace filters as they get nasty. The filters last longer if you rotate / flip them periodically.

Better than off brand
Good filter, better than the cheaper off-brand ones that I tried as a replacement, which didn't last as long and began to smell.

I'm very satisfied with the wicking filter. My house doesn't have static electricity any longer. That's amazing to me.

Thank goodness the outer blue layer of the filter was restored a few years ago. At one point only the white part of the filter was produced and fell apart after a few days. WIth the blue layer the filter works very well again. Lasts a month or more.

The humidity in the house went from the low 30s percentile to the low 40s percentile when I changed filters.

I had tried filters that were not made by Honeywell, and their quality was not as good.
