Had mitigation done this past February. Pre-mitigation levels (using a digital tester from Amazon) were between 225 - 350 in the basement bedroom where my daughter sleeps. Started switching furnace fan to run intermittently which lessened the range to 175 - 250. Decided to go ahead with mitigation.
After mitigation, digital tester showed 15-30.
Still did the little puck thing post mitigation to be sure. Tested for 90 days. Levels came back as 32 +/- 6.
