Easily Attachable to Furnace Filters – Our filter whistle easily attaches to a new furnace or air conditioner filter and sounds when your filter becomes 50% clogged, letting you know it is time to replace the filter. The furnace filter whistle is reusable. Individually packaged with simple use instructions.
Promotes Better Energy Efficiency – Clogged filters running in your furnace could result in your heating/cooling system to operate less efficiently. By installing filter whistles, you can help keep your home heated/cooled more effectively, while avoiding the wastage of energy.
Green Savings – Since you are regularly changing your filters and keeping your furnace clean, you can avoid spending as much as 15% extra on home heating and cooling costs.
Reusable – One of the best things about using furnace filter whistles are that they are reusable. As soon as the filter is clogged, you are informed about replacing it. You can remove the whistle from the old filter and equip it on the newer one. This ensures you don’t have to spend extra money buying a new whistle repeatedly.
