Energy use varies by model, fan speed, and local electricity rates, so treat these as general guidelines rather than exact figures for any one home.
Is it expensive to run an air purifier 24/7?
Generally no. Consumer air purifiers draw modest power, especially on lower and night settings, so running one continuously typically adds only a small amount to a monthly bill. Higher fan speeds use more energy than Night Mode, so a unit that runs quietly and efficiently at low speed keeps costs down.What about filter replacement costs?
Filters are usually the larger ongoing expense. The AirPro’s HEPA 14 filter lasts roughly 6–12 months depending on air quality and runtime, and replacement filters are priced from $29.99 for a single pack. A filter subscription takes 20% off and ships every 90 days, and it includes a lifetime warranty.What makes filters wear out faster?
Heavy use during events like wildfire smoke, homes with multiple pets, heavy dust, or running on the highest setting all shorten filter life. The AirPro’s smart tracking estimates remaining filter life so you replace it on time rather than guessing.How do I keep total running costs low?
- Run on a lower or Night Mode setting when air quality is good.
- Clean the pre-filter regularly so the main filter lasts longer.
- Use a subscription to save on filters.
- Size the unit to the room so it doesn’t run flat-out — see room coverage.
Total cost of ownership
When you add modest electricity to periodic filter changes, a HEPA 14 purifier is an inexpensive long-term investment in indoor air quality — often less than the recurring cost of allergy medication.
