Lint build-up is the cause of 40 clothes dryers catching fire every day in the U.S. alone, creating millions of dollars of property damage each year. The LintAlert is a simple-to-install device that can alert homeowners to any airway blockage or restriction in the dryer vent system.

It has two main parts. The SmartTap fitting installs in the dryer’s transition hose at or near the dryer’s exhaust port. It monitors the pressure throughout the exhaust conduit by using a pressure differential sensor. If it detects an increased back flow pressure caused by any blockage or restriction, it immediately sends a signal to the alarm module through its flexible six-foot 1/8″ tube.

The LintAlert’s transparent lens normally glows a steady blue. As lint builds up and air becomes restricted, that changes from green to yellow then to red. You can mute the alarm (why would you want to?) by pressing the control button once. This leaves the flashing LED lights as a reminder to maintain your dryer’s exhaust. Forget or procrastinate and more LED’s flash, indicating greater fire danger AND greater wasted electricity. This potentially life saving device is available online for US$44.90 including shipping.

The LintAlert is a smart, easy-to-install home safety device that monitors and displays the back pressure levels found in the exhaust conduit of the dryer. Pressure levels found in the dryer duct typically increase over time due to lint build-up, animal nests or vent hoods that become inoperable.
