I found you on-line as switch from where I was buying and the filters seem to be good. I only have 2 cold air return and change them every 3 months so 6 lasts me a year. The other company would send the filters and one month later start sending emails that it was time to order. They did that almost every week. A reminder once in awhile is a great Idea but weekly is a bummer. Please don't do that.
