Passive or active radon system a pipe is not a fan
A passive system is a sealed pipe from under the slab to above the roof, with no fan. Warm air rising in the pipe can pull some gas. An active system adds a fan. The vacuum then holds in summer and winter. Passive helps. Active is what you add when the test is still high.
You do not pick from a catalogue first. You measure. If the passive stack leaves the bedroom over 200, add the fan rather than drilling a second hole at random. New homes. How the system works.

The 4-day test is a first reading. The 91-day test covers the minimum of three months Health Canada asks for. Both are $59 before tax. Shipping, the prepaid return and the lab are included. Tax is extra. The PDF report goes out within 2 business days after the lab receives the detector.
Above 200 Bq/m³, mitigation starts with a quote. Gaz Radon is C-NRPP certified for testing and for installation, and ships kits across Canada.
