How it works:

 

Clicking the orange "Get Tracking Code" button takes you to a simple registration page. Complete the registration form and click the SUBMIT button there.

You will receive conformation emails with a tracking receipt, an explanation of the tests to be performed, along with packing and shipping instructions.
 

Print the tracking email, pack and ship the filter with the tracking printout as instructed.

 

Results are returned to you via email usually within 7 days of receiving the filters.
