One common here question is, "Can I leave my air purifier on 24/7?" The answer to that is, it depends on a number of key factors. These could include the brand and model of your air purifier, the size of the area, and the specific air quality issue you're trying to resolve.

Having an air purifier running 24/7 isn't inherently harmful. But, to make the most of it, there are some things you have to bear in mind. Potentially, you could end up using more electricity than necessary and cause quicker wear and tear on your device.

But for those who live in highly polluted areas or during periods of high pollen, keeping the air purifier running non-stop could be advantageous. Air purifiers have been engineered to clear the air of particulates; hence, if your place has a constant influx of these pollutants, keeping the purifier on may help in effectively eliminating them.

Ultimately, whether you should leave your air purifier on continuously or not depends on your personal requirements and circumstances. Though air purifiers can be turned on 24/7, considerations should be made regarding energy consumption, the lifespan of your device, and your particular needs concerning air quality. Consulting with an air quality expert can help you make the most informed decision for your health and happiness.
