In the bedroom, you can place an air purifier on a windowsill or even on the bedside table. The best location of the air purifier would be on the wall. Of course, to suspend it on the wall, you have to raise it and secure it in the same way you would hang a picture. In short, keep an air purifier away from the ground.
The best place to place an air purifier is somewhere in the breathing area. The closer the unit is to your head, the shorter the distance clean air must travel before it reaches you. In the bedroom, this usually translates to putting the air purifier on a nightstand or on a bedside table near the bed. Air purifiers are great for extracting air.
However, the more air available to them, the faster they can clean it. That's why air purifiers work best when placed in open areas. Placing the purifier near a window or near a door is usually your best option. Placing an air purifier in your bedroom can allow you to breathe clean air for hours, something you may not be able to experience during the day.
This can block the air intake and reduce the rate at which the unit can absorb and clean the air in the room. Once you have purchased it, the next step is to figure out where to place the air purifying devices for the best possible result. However, to make the most of indoor air quality, you need to make sure that your air purifier is in an ideal place, such as your nightstand, while you sleep. It's usually a good rule of thumb to make sure the air purifier has at least one foot of space in the front, back, and side so that it cleans the air in the entire room rather than just a small corner.
Since air will flow wherever there is an opening, the air cleaner will attempt to extract air from the outside if the doors are not fully closed. Placing the air purifier three feet above the ground can help you capture air that flows both vertically and horizontally. If you want to use the air humidifier in your kitchen, it's best to place it away from the stove when cooking and from the kettle when it boils. When you open windows or doors, you let in outside air that contains particles that the air cleaner is actively trying to remove.
If you make this mistake, you'll have polluted air that isn't filtered enough, and you're basically getting nothing from an air purifier. The reason is that the air needs to flow and if the air is drawn out or pushed from different directions, an air purifier simply cannot remove all the particles suspended in the air in the room. You can place an air purifier that is too powerful in a room that is too small and thus spend money running the air purifier for nothing. By placing an air purifier 3-5 feet above the ground, you can capture both horizontal and vertical air movement.
In a higher position, small air purifiers will work better because they don't need to suck in air from below. Placing the unit on a nightstand near your bed, away from any obstructions, gives you the best chance of efficiently removing air pollutants and delivering clean air directly to you while you sleep.
