Use a Certified Air Purifier

If you want to save on your utility bill to the tune of $30 per year, shop around for an air purifier that is ENERGY STAR-certified. Many of the big reputable manufacturers create plenty of models that are certified to be energy efficient. The only downside here is there may be a higher-than-average upfront cost, so keep that in mind as you shop. The lifetime utility savings may offset that cost.

Do Not Run it Continuously

That aforementioned 550 kWh mentioned earlier regarding the standard energy usage of an air purifier was for a model that has been left running all of the time. You can cut down the energy usage of your air purifier by only using it when needed. Experiment with usage to find the best setup for you and your home. You may be surprised at how little you need to run your air purifier.

Use it on a Low Setting

Another tip is to simply run your air purifier at a low setting. Those ENERGY STAR statistics assume an air purifier is running at its highest setting, after all, so you can save a few bucks on your monthly electricity bill by keeping it at a low setting. Feel free to crank it up to a higher setting when needed.
