A common misconception is that an air purifier can provide adequate air purification after an hour or two of operation. In contrast, air purifiers are designed for continuous use for a period of time. Humans, pets, air conditioning systems, and open windows are constantly bringing new pollutants into the room.
Therefore, the best solution is to run the air purifier 24 hours a day. However, this can wear out the filter and the machine itself. Therefore, adjusting the time of the device on depending on the extraction rate of the air purifier you’re using.
The air extraction rate means the amount of air the device can clean in an hour. The pumping speed of an average unit is about 6 air changes an hour. With this information, you could run your air purifier for about 10-12 hours a day. However, the runtime will depend on the brands, model, and type of your air purifier.
Is it safe to run an air purifier all the time?
These devices can operate uninterrupted without the risk of malfunction or danger, so it is safe to run the air purifier at all times. You can keep your device running so you can get home and breathe fresh air when you leave the house.
Indoor air gets quickly contaminated, so, turning the air purifier on and off does not get rid of contaminants effectively.
How long does an air purifier to clean a room?
It takes an average of 30 minutes to 2 hours for an air purifier to clean the air in the room. After running the air purifier for 20 minutes, you will see a difference in the quality of the air in the room. The actual effect of an air purifier depends largely on the air extraction rate (air changes per hour), the model, and the size of the room to be purified. The air extraction rate is the amount of air that can be purified from the room in one hour. For example, a HEPA air purifier that operates with four air changes per hour (15 minutes on a single charge) only takes half the time to clean the air compared to an air purifier that operates with two air changes per hour. Location and weather are also important factors affecting the speed of air purifiers. In summer, there are many pollutants such as pollen, and air purifiers take a long time to purify the air. Finally, the air purifier must have sufficient airflow capacity to meet the size of the room.
Can I open my windows with my air purifier on?
This question is very subjective as it depends on the quality of the air around your home. If the air pollution is severe, be sure to close the windows and leave it to the air purifier.
However, if the air is not polluted, it is advisable to occasionally open the windows and add fresh air to the house before closing the windows.
Can I turn off my air purifier when I sleep?
You can keep the air purifier on because when you fall asleep, you are still breathing. If you need a good sleep, the air you breathe during sleep is very important.
By turning on the air purifier, you can remove bacteria, pollen and dust during sleep and improve the quality of your sleep. Therefore, it is highly recommended to leave the air purifier on during sleep.
