This product works well. We run humidifiers every night and use filtered water. These need to replaced at least every 2 months, so I order extras to have on hand.

I haven't had to replace the filter yet in our humidifier. I looked on amazon as to how to lengthen the time for replacement. I use distilled water in the humidifier/pour undiluted vinegar on the filter it came with and let it dry completely before putting the humidifier back together.

The new blue wrapped filters are even better now. I've been using these for years and appreciate Honeywell adding that wrapper -- it keeps the filter in place and seems to keep it from getting yellowed. Thanks Honeywell!

I have been purchasing my filters thru the Honeywell Website as the price per filter, even with shipping charge is cheaper than any other site. Each filter last over 3 months, as long as you have the Humidifer in clean open area.
