Product review (3 stars): Overpriced Quality Filter
These filters hold up well...well enough that I just replace it once a year.  I toss the old one when I put it away in the spring and start with a fresh one in the fall.  I'm not sure why, but they are much cheaper ($4.50 + a few dollars s/h depending on quantity) through the Lasko's online store at [...] than Amazon's current price of $20.22.
