As shown above, a MERV 11 rated filter will remove particles that are down in the 1 micron size range! (That's 1/50th or 1/100th of the thickness of a hair!)81% (9)
instrument-a-day 6: humidifier
This humidifier runs next to my bed all night in the winter. Sometimes its groans and whirs are so interesting that they keep me awake and I have to turn it off. It plays little cadences, drones, and repeating beats that constantly change. Or I'm just hallucinating in my half-asleep state. I've been meaning to record it for months. It didn't do anything particularly exciting during these 45 seconds, but you can hear it subtly change even in that time.New Humidifier Plates
These are the new fiberglass plates for the humidifier. $7 From Johnston Supply on Elston. The flap of the box had a warning to turn off the furnace before changing these, to avoid blowing LIME DUST into your face. I'm guessing there is lime powder on these plates as perhaps an antimicrobial agent. Based on the previous picture, it's clearly only effective for so long.
Humidifier filter removes mineral and pollutants from water. Filter discoloration is natural and will carry depending on water. Replace filter about every two months (depending on use and local water quality) or when performance starts to deteriorate. Help keep your humidifier clean and extend filter life by using other Honeywell accessories including antibacterial treatment (HAC100). This helps control bacteria and algae growth in your water tank, and provides odor free operation for use in evaporative humidifiers only.Related topics:
