Should You Leave an Air Purifier On All Day? - The Benefits of Continuous Use

Leaving an air purifier on day in and day out is the best way to ensure the highest possible air quality level. Air purifiers drive air through their filters to purify it, so that you can maintain the high quality of the air in your home at all times. For optimal performance, all air purifiers must operate continuously. When the air purifier is turned off, indoor air pollution returns to its original state.

To take full advantage of the incredible benefits of breathing clean, fresh air, good air filtration must be maintained inside the home or office. This means that you are justified and expected to use your air purifier for as long as possible to clean the air in your room as efficiently and thoroughly as possible and, among other things, to keep air quality at a high level for as long as possible. If you run your residential air purifier all the time, you can keep the air in your home clean and prevent new pollutants from accumulating. On the other hand, if you leave the air purifier on all the time, the air will be continuously filtered and new contaminants will be eliminated as they are introduced.

Some air purifiers need longer operation, while others can filter room air at high speed thanks to high air flow. When it comes to energy efficiency, every air purifier approaches it differently. As long as you follow our shipping instructions, we will pay the shipping costs of the covered product for repair and back to you. In short, there's always room for savings. It may be too much information to collect, perhaps the easiest thing to do is to turn on the air purifier and leave it on, but if you want to get the best performance, optimal consumption and clean air in your room on a consistent basis, I recommend that you follow these suggestions.

More importantly, turning on the air purifier at intervals won't help your cause, as it won't generate the clean indoor air you want. Turning a purifier on to work for a couple of hours and then turning it off again isn't exactly the most effective approach. Keep in mind that if the air purifier has a CADR of 120, this value only applies to the maximum speed and has several times less CADR at a lower speed. Most HEPA air purifiers use a low amount of energy: around 50 to 100 watts of energy per hour depending on the speed of air flow. If you've just started using an air purifier, you've probably wondered how long you should keep it on, in addition to the many questions you can think of about using an air purifier.
