I bought two of these filters after reading about your company and how they make filters themselves. The reason I ordered two of these was so while one is being cleaned and dried the other can be installed and left in place until the desired time before a filter change is required. I only recently installed them and will try to edit my sister's review so I can tell you how well they work or not. The price was not the decisive criterion for me, what was more important was how the filters were put together, how they were made and where they were made.
