Where should I place my air filter?Updated 7 months ago

So long as the air purifier is sized properly for the room in which it's used, it can be placed anywhere you have a power source, but for optimal performance, it should be centrally located within the space. One thing to consider is whether to place it near an open window. The answer depends on your outdoor vs indoor air quality. If the outside air is full of bothersome allergens, try to place the purifier near the window. If the outdoor air is cleaner and fresher than your indoor air quality, opposite a window on the other side of the room may be preferable. Also, read your air purifier's owner's manual. Air purifier design and technology vary widely from brand to brand. Your owner's manual is your best resource for addressing installation, replacement parts, maintenance concerns, and more.
