A recurring inquiry from air purifier users is whether keeping it on 24/7 is advisable or not. The answer to that is, it depends on a number of key factors. Things website such as your specific air purifier model, the capacity of your room, and your unique air quality demands can all play a part.
Keeping an air purifier on all the time is not harmful per se. Nevertheless, there are factors that you must consider for optimized performance. Potentially, you could end up using more electricity than necessary and cause quicker wear and tear on your device.
That being said, in polluted areas or during allergy season, leaving your air purifier on 24/7 might be beneficial. The role of air purifiers is to filter out particles from the air, so in spaces where these pollutants consistently infiltrate, it might be useful to have your purifier working constantly to tackle and remove them.
Ultimately, whether you should leave your air purifier on continuously or not depends on your personal requirements and circumstances. While air purifiers can operate around the clock, keep in mind the power consumption, your device's longevity, and your specific air quality requirements. To make an informed decision, you should consider seeking guidance from an air quality expert.
