Cheaper than the others, and they fit!
on August 21, 2011
I have two Holmes HAP240 air cleaners, and these after-market versions fit as well as the originals did, and for less money! They're probably greener too, because they're cardboard, not plastic.
Reading through customer reviews, I found a great tip. You can make your filters last at least twice as long by wrapping the filter with a Swiffer dry cloth (for the Swiffer Sweeper). Put the Swiffer cloth on the intake side of the filter and fold the edges around the filter. This gives you a cheap pre-filter that makes the filter last a lot longer, and fit more tightly so that dust doesn't get dragged in the edges. Then every couple of weeks, change the cloth!
