An air purifier can significantly enrich the air quality in your home, but many question the safety and efficiency of having it operate 24/7.
Simply put, yes, you can run an air purifier 24/7, but there's more to understand about this here topic.
Different types of air purifiers might have divergent abilities; some are engineered for 24/7 operation, while others might need occasional breaks.
Secondly, the state of your indoor air should be considered. If you live in an area with excessive pollution levels or have a member in your household with allergies, a continuous operation could be necessary.
Energy efficiency is also a factor to consider. Although air purifiers are not big energy hogs, leaving one on continuously will raise your electricity bill.
Another consideration is the noise made by the purifier. Not all units are silent, and having them run all the time can disturb rest or sleep.
To sum it up, while it's usually okay to run an air purifier all day long, one should consider the type of purifier, the indoor air quality, its energy consumption, and the noise level before deciding.
