Given the size I thought I would have to go to a speciality store to get replacements. I did a search and found these online and ordered them. Shipping was relatively fast. And they fit perfectly. As far as a good value it just depends on the qualities of the filters. I later found some filters at a big box store for about the same price. But some with perhaps better filtration and allergen eliminators were 2-3 times the price.
