Review on GOGOGlobal Humidifier Compatible Honeywell HAC 504AW by Epickson Palma

These filters seem to last longer and work better (looks like they're better built, two layers, blue mesh and filter) than the ones I've bought before (at Revain). Not yet installed or used. MFT After installing and trying these filters, I concluded that they were useless. The design looks nice, but they don't work as humidifier filters. Not much water evaporates. The humidifier tank is still full of water after several hours of operation. My last purchase of filters worked well for a humidifier but was short lived (became yellow and hard after a few weeks). They look good but don't work. How can I return them for a REFUND? MFT
