Hopefully by now, you have purchased and placed a CO Detector in your home near all bedrooms. These units will normally sound an alarm if the reading surpasses 70 PPM for a period of 2 hours. We are very excited about a new product which mounts in the airstream of your furnace and will shut the furnace down if 50 PPM for 2 minutes is detected. Shutting down the source and not allowing the concentration to increase is very exciting. We will blog more as more information is available on this new, exciting product.
