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. 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. Consider placing the air purifier near a window or door. Placing it next to a window or door is like using it as a first line of defense, taking out all the air as soon as it enters that space. However, if the door or window is open, that makes the purifier work harder.
Avoid keeping doors and windows open while operating the air purifier, otherwise there will be an endless stream of dirty air reaching your purifier. Give him the time he needs to address the air that is already in the space before introducing more air. If the problem is dust, pet dander, then the best location of the air purifier will be a living room. And if you are deeply concerned about the air when you sleep, it's also a great option to put an air purifier in the bedroom, after all, we all spend eight or more hours in the bedroom.
Using your air purifier in the living room is a good option, especially if you spend a lot of time in that room. One of the best places to place an air purifier is near any source of air infiltration, such as a window or door. By placing an air purifier on the floor (3 to 5 feet is perfect), it not only captures the horizontal movement of indoor air, but also exposes an air purifier to vertical air movement. In addition, it is best to keep the air cleaner away from moisture sources to prevent condensation damage.
Keep in mind the additional advice (you'll find it under the 7 basic rules) related to the air purifier that is portable (you can and should move it to achieve the maximum air cleaning effect). However, the effectiveness of an air purifier is not as high as it would be with a closed window; but that would also mean that there would be no fresh air. If the air purifier is too heavy and too large to move from one room to another, then you should place it in a room with more pollution. Humidity causes the air to become heavy, which causes the purifier to work harder, which is not good for it.
Hi John, Placement close to the origin of the air particles (cat hair, in this case) is the right move. The lower floor generally receives more airflow and also contains more “heavy” particles; in theory, placing an air purifier on the lower floor would be a smarter idea. Having a HEPA filter in the overhead purifier could have a positive impact on the air quality above, compared to a non-HEPA air cleaner. Hi Luis, The dog's hair and dirt are usually found on the ground; a pre-filter will take care of the largest particles, such as dog's hair and dirt, and an activated carbon filter should eliminate odor.
However, getting as much air as possible into the air cleaner can help the air cleaner clean the air faster. If you have an ionic air purifier, this is especially important because of the way ionic air purifiers work. The upper floor should have a relatively higher concentration of smaller particles (lighter, warm air rising upwards could carry them with it).
