For Electric Customers
An air purifier is a device which removes contaminants from the air. Air purifiers are commonly marketed as beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke. Dust, pollen, pet dander, mold spores and dust mite feces can act as allergens, triggering allergies in sensitive people.
How does an air purifier save energy?
How do I choose the right size air purifier?
- ENERGY STAR® models use less electric energy to remove particles from indoor air.
- ENERGY STAR models are also 40% more energy-efficient than standard models.
- Consumers can save about 340 kWh/year or $30 annually on your electric bill.
The ENERGY STAR specification for room air purifiers measures energy efficiency by using a CADR/Watt ratio. The CADR measures the volume of air cleansed by the specific type of pollution - like tobacco smoke, pollen or dust. Air purifiers are number rated for effectiveness of removing these particles. The higher the tobacco smoke, pollen and dust numbers, the faster the unit filters the air. Ask your retailer which air purifiers would work best for your rooms, or you can refer to the individual manufacturer website for more information.
