Run your air purifier 24 hours a day.
How Long Should You Run An Air Purifier
At least 12 hours a day but for the best result, we recommend keeping your air purifier running 24 hours a day as dust and airborne particles will circulate nonstop throughout the day. With constant clean air, you can breathe more comfortably without allergies like cough, sinus being triggered. To optimize the performance, set it to full speed for a couple of hours and switch back to low speed to maintain the room air quality standard. Also, run your air purifier daily or as often as possible to ensure the air is always clean and fresh every time you come back home.
How Long Does It Take An Air Purifier To Clean A Room
On average, your air purifier would take 30 minutes to 2 hours to purify the air in a room. You should notice a difference in the room air quality after 20 minutes with a running air purifier. In order for an air purifier to be truly effective, it is highly dependent on the extraction rate (air changes per hour), model type, and the room size that needs purifying. The extraction rate is a figure of how much air can be clean from a room in an hour. For example, a HEPA air cleaner running at 4 air changes per hour (15 minutes one charge) would only take half the time to clean the air compared with an air cleaner running at 2 air changes per hour. Location and weather also play a big factor in how quickly an air purifier will work. There are more pollutants like pollen during the summer thus an extended period of time is needed for an air purifier to clean the air. Lastly, the air cleaner must also have enough airflow capacity to fulfill the room size.
Many people would have a misconception that running an air cleaning machine for few hours is enough to provide you with clean air for the rest of the day. That is not the case as airborne pollutants never stop and an air purifier is designed to run round the clock without fail. Every time an air purifier stops running, airborne pollutants will start to build up and your room will get contaminated again. The entire air cleaning process will have to restart and it takes time to achieve the optimal result. The only downside of leaving an air cleaner running continuously is the cost. You should expect an increase in utility bills and the filters to worn out quicker thus more frequent filter replacement. Then again, it is a small price to pay for a healthier and happier you. Your body will thank you in the long run.
