Collected 2.5 oz of filth from the air
on February 6, 2011
I foolishly put off replacing my filter for about 1 year. I figured I could get away with it because I keep a very clean house. I'm allergic and my kid has asthma, so I'm always dusting with Swiffers, microfiber mopping, etc. Nobody smokes around here; there are no pets; the windows are closed 9 months out of the year and the rest of the time we use window air conditioning units. Nevertheless, when I went to change my 200PF HEPA filter, I noticed that while the new one was translucent and white, the old one was dark grey and opaque. Curious, I weighed the filters on my postage scale. The old one weighed a full 2-1/2 oz more than the new one. I know it wasn't moisture, because my air is bone dry. Nope -- the filter was saturated with 2.5 ounces of particulate gunk that would've been destined for my family's lungs.
Suddenly it doesn't seem like such an indulgence to replace the filter every six months.
