Do I Leave the Air Purifiers on All Day?

Each purifier has its own strengths and weaknesses.

Though they come from numerous manufacturers, air purifiers – also known as air cleaners – all serve the same purpose: filtering indoor air pollution such as dander, dust, mold, pollen and smoke, thus reducing nagging allergies and asthma attacks. Though most air purifiers cater to all-day operation, each individual unit is different. Consult your purifier's instruction manual to find what's best for your specific model. Have a question?

All-Day Use
Air purifiers suppliers and manufacturers generally recommend running air purifiers all day for maximum operation. For instance, air purifier manufacturer MORCK says that running an air purifier all the time provides “year-round benefits.” Honeywell, another manufacturer, echoes this sentiment, encouraging owners to run air cleaners as much as possible, or all the time for the greatest efficiency. As a general rule of thumb, use your purifier's medium setting when running it all day for energy efficient operation. Use the high setting for quick air circulation and filtration; use the low setting for quiet operation.

Effectiveness
Depending on the size of the model, air purifiers filter the air in spaces ranging from about 100 square feet to 5,000 square feet. In most cases, however, a purifier will not purify the air in an entire home, even if you leave it on all day, due mostly to walls or other partitions. Approach air purification on a room-by-room basis, installing units in the rooms you occupy most. Use an air purifier in the bedroom first, as most people spend about a third of their time there. Fan speeds, in-room airflow, insulation quality and the proliferation of pollutants all affect the effectiveness of air purifiers.

Energy Consumption
According to air purifier supplier Morck Electric Appliance, the average HEPA – or high efficiency particulate air – filter-equipped air purifier uses about 50 watts on its lowest setting and 200 watts on its highest setting. In comparison, the average computer uses about 365 watts. As such, most purifiers won't leave a significant mark on a power bill, even when running all day. Look for air purifiers with the U.S. Environmental Protection Agency's Energy Star seal; these units are more energy-efficient than air purifiers without the certification.

Filters
Though running the air purifier all day is recommended, doing so causes air filters to run their course more quickly than sporadic operation. Though the typical HEPA filter needs replacement only once every three or five years, pre-filters and carbon filters need replacement every three to six months. Consult your air purifier's user manual for filter changing guidelines.
