In today’s world, where air pollution is a major concern, an air purifier has become an essential appliance for every household. It helps improve indoor air quality, but many people worry that running it all day might increase their electricity bills. This article shares tips on how to use your air purifier efficiently and cost-effectively.
How to Calculate Electricity Usage for an Air Purifier
You can estimate your air purifier’s electricity consumption using this formula:
(Wattage × Number of Units ÷ 1,000) × Hours Used per Day = Units per Day
Example:
If your air purifier uses 55 watts and runs for 24 hours:
55 × 1 ÷ 1,000 × 24 = 1.32 units/day
If the electricity rate is 5 THB per unit → 1.32 × 5 = 6.6 THB/day
Over 30 days, that’s about 198 THB/month.
Use the Air Purifier in a Closed Room
Avoid opening doors and windows unnecessarily. This allows the purifier to clean the air efficiently without overworking. Using it in an open room lets dust and pollutants continuously enter, making the device work harder and shortening its lifespan.
Choose the Right Size for Your Room
Each air purifier model specifies the room size it can handle. Make sure to select one that matches or slightly exceeds your room’s size. A larger-capacity purifier can operate more efficiently without running at full power all the time.
Pick a Washable Filter Model
Most conventional air purifiers require filter replacements, which can be costly. However, advanced models feature washable and reusable filters, saving long-term maintenance costs. When buying, look for purifiers with washable filter technology for better value over time.
