What is the Best Location for the Air Purifier?

The best way to control air pollutants in your home is with an air purifier. These are also perfect for sufferers of asthma or allergies. These machines are also useful in removing smells, such as cigarette smoke or cooking odors, and give the air a nice clear and clean feeling.

Many buildings and homes may have air purifiers built directly into their heating and cooling system. However, there are plenty of air purifying devices on the market that are just as beneficial. The primary concern with these free-standing devices is knowing the best place to place them. Here we give suggestions on the most useful areas of the house for air purifiers.

Know Your Needs

The room sizes vary for each individual use. Room sizes may also influence the efficiency of the air purifier, as the machine will need to cycle the air in the room constantly. For example, a more efficient machine will require fewer cycles to purify the air thoroughly. Other factors include the type of activities, a number of people in the room, opening and closing the door, or the presence of pets. These activities allow dust or other air pollutants that may have settled on the furniture to be stirred and mixed into the air.

Another factor is the type of air purifier that you may need. A larger machine will be able to cycle air more efficiently in a larger room compared to a smaller machine. However, more massive machine will also create more noise. A smaller and portable air purifier will be easier to move between rooms but may take longer to cycle the air.

Air purifiers will also need to be regularly maintained. Dust buildup on the outside can be easily cleaned with a damp cloth. Most air purifiers will have air filters that need to be regularly cleaned or replaced. Modern air purifiers can be Wi-Fi enabled or have displays that will remind you when a filter needs to be cleaned or replaced.

Consider location and Source

There are three primary considerations for placement of an air purifier. First, be sure the placement is in a safe area. Do not place it in areas that will block the walkway. However, the machines should not be put in the corner. Most air purifiers have air intakes located in front and output based on the back. The air intake and output locations should be kept clear, and the air intake should face as much of the room as possible. Keep at least a couple of feet clear from the top and sides of the air purifier.

The second consideration is to place the machine closest to the source of the pollutant. The closer the machine is to the source, the faster it will trap any air pollutants. For example, if there is a strong odor seeping into the room, place the air purifier near the vent closest to the source. Kitchens and bathrooms are also popular places for air purifiers, as they may trap any lingering odors from usage.

The final consideration is the location of other electronics in the room. Air purifiers may use a frequency similar to TVs, microwaves or stereo equipment. This may cause interference and cause disruption during usage. Air purifiers are generally safe for use near a computer.

Keep the Door Shut

For best results, all doors and windows to the room should be kept shut. This will allow the air purifier to cycle cleaner air. Any unforeseen openings to the hallways or other rooms may lead to contamination that will reduce the efficiency of the machine. Furthermore, any pollutants from these areas will mix with the air in the room and decrease the machine’s efficiency.

During hot summer days, an air purifier can be placed next to an open window to trap any entering particles. However, remember that the air purifier does not do well under extreme heat. Be sure to find a safe, dry and cool location if a window is to be opened.
