Product review (4 stars): the price is right
While I purchased based on the price the description is the same as the brand name.  However this product is thinner and  more flimsy but it does work.  I purchased 1 of them and did read the other reviews.  I may buy them again because they do work but the quality is not as good but knowing you get what you pay for.  I gave it 4 stars because it arrived in a timely manner although the box was crushed It didn't damage the filter.
