Why do I need a plug-in radon meter with an audible alarm?

  1. All radon systems fail. To make an immediate repair just plain makes sense.
  2. A plug-in meter works 24/7/365 without having frequent battery replacement
  3. If your radon system has failed, you will want to get it fixed under warranty. Even a most generous warranty is of no value if you do not know that your radon system has failed.
  4. Homemade filters are commonly installed on fresh air radon systems. When they clog, radon reduction stops. Homeowners very often forget to service homemade filters every 60-90 days. It is not unusual to see a system that has not worked for 15 years due to a homemade filter that had never been serviced.
  5. A radon meter alarm will remind you to service a homemade filter every 60-90 days if that is what you have.

Why do I need an electronic humidity controller?

  1. An electronic humidity controller can prevent high indoor relative humidity and mold from radon system operation.
  2. A mechanical ventilation system can add large amounts of moisture into a breathing zone each day. In a hot, humid climate, each cubic foot of outdoor air added into a breathing zone for 24  hours adds an annual average of 1.62 pounds of water. Some radon mitigation systems add 50-100 cubic feet per minute of hot humid air into the breathing zone.
  3. A mechanical ventilation radon system can easily add more moisture than an air conditioner can handle resulting in high indoor relative humidity.
  4. Building scientists suggest that to prevent mold, indoor relative humidity should be kept below 60% most of the time..
  5. An automatic humidity controller can temporarily shut down a radon system if it causes indoor relative humidity to rise above 59.9%, thereeby preventing the radon system from causing mold.
