Reduce energy costs with our air filter replacement alert. Dirty air filters force the blower in heating and cooling systems to overwork, raising energy costs.
- They emit a whistle when dirt builds up in the filter, signaling that it is time to change it for maximum energy efficiency.
- Attaches to all 1" filters
- 2 position flap allows whistle to work with both fiber and pleated filters
- gradually notifies you when it is time to change your air filter
