Air purification is an important part of maintaining a healthy home environment. But when it comes to using an air purifier, should you keep the windows and doors closed? The answer is yes. Tests have shown that keeping doors and windows closed while using an air purifier can reduce particulate pollution levels by up to 50%. This is because when the windows and doors are open, more contaminants can enter the room, and the air purifier has to start the air purification process again.
Smart Air, a social enterprise certified by B-Corp, offers simple and practical air purifiers and free training to protect people from the harm of air pollution. It is important to note that some air purifiers are designed to work best when they're exposed to fresh outdoor air. If you open a window while your air purifier is in operation, make sure it is designed for outdoor use. It is also important to monitor the filter when using an air purifier with the windows open, as it becomes less efficient at cleaning the air in your home when the filter becomes clogged with pollen or other air contaminants.
CK conducted tests on two days when outdoor air pollution was severe (February 14 and 15) to determine how opening windows affects indoor air pollution levels. To keep the reference pollution level constant in all tests, CK opened the window to let in outside air (and outdoor air pollution) until the particulate pollution was the same as outside. However, if the air purifier in the house is equipped with NCCO oxygen polymerization air purification technology, formaldehyde can be completely purified without opening the window. In conclusion, it is recommended to keep doors and windows closed while using an air purifier for optimal performance.
If you need to open a window while using an air purifier, make sure your device is designed for outdoor use and monitor its filter regularly.
