Product review (4 stars): Great Filter
I really like the fact that I can buy these filters in bulk vs. buying them individually from Wal-Mart.  Also, 99% of the time Wal-Mart does not have them in stock (I assume due to high demand).  I would give it 5 stars, but the shipping is rather steep given the fact that the filters weigh very little.  Although, the seller does ship them rather quickly.
