I purchased seven filters all together. Two different sizes for two different houses. They all came in one box, wrapped in one piece of plastic. I had to wrap the filters that I was not ready to use, to try to keep particles out of them. I need to talk to you about Maya I emailed about this issue, and never got a response.
I have been buying Phil treat filters for more than 20 years. Their product and service are great and we do not see the need to stop. I have also recommended you too many of my friends.
