These pages were designed as parent pages to the product pages (where you can purchase the item). They may look like a different style than the header and footer but I used only styles found/inspired by other parts of the website, and I standardized styles where I could. 

For the Replacement Filters page I thought that selecting the system you own would be from a picture easier than selecting the replacement you need from a long list, especially since all the replacements look about the same.
