Fits: aprilaire humidifier models 350, 360, 568, 560, 600, 700, 760 and 768
Also fits: HONEYWELL models HE260, HE265, HE360 and HE365
Do not wash: if you wash the vapor pad in an attempt to remove the built up water deposits, you’ll also wash off the hydrophillic coating; your humidifier is then unable to provide humidity to your home
Replace 1-2 times per humidification season
