When it comes to air purifiers, the cost can range from as little as $30 to as much as $180. This price range is suitable for most people's homes and will provide a quality air purifier that will last for years. While there are more expensive models available, they are often not worth the extra cost. The power consumption of air purifiers is usually quite low, with wattage ranging from 20 to 100 watts (for the largest units).
This means that leaving the air purifier on all day and night will have minimal impact on your electricity bill. It's important to note that the operating costs of air purifiers do not increase linearly with room size. To get a better idea of the operating cost of air purifiers, it's best to analyze the costs by room size. However, even the best air purifier won't be able to clean 100% of the air in a room. For this reason, I recommend investing in a personal air purifier that can be plugged in via a USB cable and works like a normal air purifier. The most energy-efficient air purifier on the market is the Powermatic PM1250 (learn more on Amazon here).
The annual cost of running an air purifier will depend on how often you change your filter and how often you use it. If you're a renter, then you may not be able to get a whole-house air purifier anyway. When it comes to installation, it's best to leave this job to a licensed HVAC professional due to the complexity of the project. As an air purifier expert, I have some great tips and recommendations on air purifiers that I have tried and found to be effective. Some use ozone, others use electrostatic plates, ions or air disinfectants.
