A recurring inquiry from air purifier users is whether keeping it on 24/7 is advisable or not. To answer that, it's necessary to consider several essential points. 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. However, there are certain considerations to keep in mind. Leaving your air purifier on constantly could result in unnecessary power usage and increased wear and tear on the unit.

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. 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.

In a nutshell, the decision to keep your air purifier running all the time hinges on personal needs and specific situations. Though air purifiers can be turned on 24/7, considerations should be here made regarding energy consumption, the lifespan of your device, and your particular needs concerning air quality. For the best outcome, consider consulting with an expert on air quality before making your decision.
