We're tired of running to the local hardware store for filters. We live in the desert so dust is a thing. Lots of dust. We change the filters at least once a month. Buying in bulk from major hardware stores just means we have a ton of filters waiting to be used. Not to mention that her MERV rating is only 11. We found them when we were looking for a higher MERV rating and signed up for automatic delivery every 2 months. That works great. We get two filters every two months so we don't have to stock up on filters or buy new ones. They work better than the ones we used.
