Air Purifier While Windows Open

The bottom line to the question.

Air purifier while windows open.

Fresh air also has oxygen which you need to breathe so you need to strike a balance. You should consider opening your window if you aren t using the air filter or if you re only doing it for a short period but only if the outdoor environment is in relatively good shape and you have a reason to. If you have used chemicals or have a source of bad quality of air like burning. Doors opened or closed it does not really matter.

It would just be a matter of how much would come in if the windows were closed. Regardless most companies will use the terms air cleaner and air purifier interchangeably. Is going to be subjective. Keep your windows open to prevent locking irritants into rooms when air purifiers aren t running.

Fresh air has pollen smoke and other potential irritants. While still at it the purifier the air in the room will not be as clean because contaminated air will still be getting into the room while at the same time some of the purified air will be escaping out. I have allergies so i use an air purifier. Most air purifiers can remove at least 99 97 of particles as small as 0 3.

New particulates swirl around in the air all the time. Air purifier windows open or closed. Even with a window open air purifiers can still meaningfully reduce particulate air pollution in the home by 60 in 20 minutes in our tests. Obviously closing the windows is the most effective but if you have to balance outdoor pollution against vocs or co2 indoors it is possible to get some ventilation and significantly reduce pollution.

Create a stronger cross draft by opening windows on opposite sides of the room if possible. However how effective the air purifier is depends on both the purifier itself and the pollution level of the air. Airflow with 1 vs 2 or more windows open can be dramatically different. With 2 or more windows open often the air purifier will have almost no effect.

While air cleaners often include filters they are overall more robust in cleaning the air than air filters. The air purifier is going to clean the area it is immediately contained to regardless. My partner likes to open windows to get fresh air. It is a common misconception that operating an air purifier for an hour or two in a room will sufficiently clean the air.

However the only limitation here is that the performance of the purifier in a room with open windows is less than one with closed windows.
