> My conclusion was that the Honneywell model is just a vehicle to sell more filters, which are not that cheap in the long run. This is every air quality device in the industry. I have an old vornado air purifier that uses furnace filters for its media. $30 for the allergen level filters, when I can find them. When the electronics crap out in that thing will be when I learn to repair fans. I had a prototype I built before I discovered these that used a 12V Molex power supply brick and a bunch of case fans to draw air through a furnace filter. I had it in a triangular box, intending to put it under a bed or a chair so it was dead silent. Then I found the Vornado and that went into storage. Higher cfm. Unfortunately the Vornado filter was built at the height of the blue LED craze. But at least it’s low lumens. |

I did not have much exposure to many. Previous to the Honneywell we had the "boiler" kind of humidifier, the one that uses two graphite electrodes submerged into water tank. Not many consumables, except that this does not work much, unless one keeps it right at their noses (as pictured on the box :). The electrodes develop some grime eventually which further decreases 'efficiency', but can be cleaned somewhat.
As for the ultrasonic one we use now, there does not seem to be any consumables as such. Maybe the ultrasonic element itself. In three years of seasonal use I can notice some either corrosion or build up on the black ring of the element, but not much difference from that.
There is some kind of filter ring, made of hard plastic, filled with small beads. But as I said in the 3 years we had no reasons to change it. Clean it, yes, but not replace it like with Honneywell.
Cleaning the thing is a drag as always. Two usual problems: the reddish mold above the waterline and inside the "gorge" and nozzle. Also the limescale, though a moderate one. We fill it with just the cold tap water, which is not too bad here.
