I just tested our TT this afternoon with the 2 formaldehyde testers that I use in my profession and both of them read 0.00 ppm. Both meters are accurate to +/- 0.01 ppm. The manual that came with one of the meters states that it is normal to find 0.03 ppm in nature.
Bottom Line - Don't worry about something that isn't there. If you're still worried about it you can buy a meter on-line from Home Depot.
