A recurring inquiry from air purifier users is whether keeping it on 24/7 is advisable or not. The question's response is dependent on a number of important 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.

Keeping an air purifier on all the time is not harmful per se. But, to make the most of it, there are some things you have to bear in mind. Leaving your air purifier on constantly could result in unnecessary power usage and increased wear and tear on the unit.

However, in polluted environments or during pollen season, having your air purifier running around the clock may be essential. Air purifiers have been engineered to clear here 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. Air purifiers can work continuously, but you must consider energy usage, your device's lifespan, and your specific air quality needs. To make an informed decision, you should consider seeking guidance from an air quality expert.
