Furnace Filter Whistle

This simple device makes a low, soft whistling sound if it is plugged into a clogged filter. Plug it into your filter to test if it is clogged, and leave in to alert you once the filter needs changing. Operating your furnace with a clogged filter can not only damage your equipment, but it can also cause your system to operate up to 15% less efficiently! Generally, these filters should be changed about every 1-3 months (during heating season). This whistle will remind you so you don't waste energy and money heating your home inefficiently.
