I am happy with this company and purchase the filters as needed for the year. They are accurate with the orders and ship them in a reasonable time frame so I do not run out. I am unable to tell how well they work but my system seems to be happy so far and this is the third year I believe that I am ordering them from this company. No complaints and every reason to be satisfied.
The filter was placed in a box that didnt quite fit correctly for the filter. As a result, a top portion of the filter was bent, found upon opening the box. I was able to bend it back enough to use the filter. But please next time, use a box that better fits the filter.
