Niagara Conservation Energy Saving Furnace Whistle

Niagara Conservation Energy Saving Furnace Whistle lets you know when it's time to change your heating/air-conditioning filter. By changing your filter regularly, you reduce the risk of breathing unhealthy air and prevent your heating and cooling system from running harder than necessary.

This low-tech tool is so easy to use. As dirt builds up it produces an increase in preasure, which triggers the whistle.

In addition to reducing your energy costs, changing the filters can extend the life of your heating and cooling units and keep them operating properly. The Niagara Conservation Energy Saving Furnace Whistle is an easy reminder to change your filter.
