Brian had the idea to write the date on the filter so you can always see when you changed it last. With the cheaper filters, we changed it about every 3 months. They were gross after 3 months, but not horrible. After a few weeks, the new expensive filter was disgusting. Really. I waited until a month had gone by, and then I went ahead and changed it. I can’t tell you the grossness that it had become. Ew. Just. Ew.

After having changed it, I looked at the new one that afternoon, and within an hour, it too had already turned from white to gray. It wasn’t severely gross yet, but definitely on its way.

So my question is: are we (Brian, me, Samantha, Molly and Maddie) THAT disgusting? Do I not dust frequently enough? Do I open the back porch door too often? Is the new filter just that good? What’s the deal? Should I use the new filters and change weekly until we get the house to a decent level of dustiness?
