The product image shows two filters which I thought I was getting. Like buying a pair of shoes and only receiving one. I can buy cheaper elsewhere.
The filter is fine. The product image is a pair of filters, which is what I assumed I was buying. I see now there is text saying it is not a pair. There's no good reason for showing a pair when the the product is a single unit.
