The noise from the unit is not even noticeable.

All in all a very satisfactory outcome

The radon level in our house was originally 500Bq/m3. Two positive input ventilation units were installed in our loft and both set on a high setting and had beading fitted between the skirting boards. This has resulted in the level reducing the radon level to an acceptable 19Bq/m3. The noise from the unit is not even noticeable. All in all a very satisfactory outcome.
