She may not have been selling anything but it sure sounds like she was qualifying you as a potential sales prospect for a furnace filtration system of some sort. Don't be surprised if you do get calls about one now.
This # kept calling for my husband, would hang up when I said he wasn't home. Then today the lady asked for my husband, by name, I said he wasn't home and asked if I could help her. She asked if I was his wife and I said yes. She said she is not selling anything but is taking a short survey. She asked a few questions about the air quality, if we has allergies/asthma and asked if we had a filter system on our furnace. She asked if I was under 85 and then she hung up.
