Things To Consider Before Buying Air Purifier

Before buying the air purifier, most of the customers forget to consider the shape of the purifier.

Size of the Purifier

If you want to know which purifier is exactly according to your needs and desires, you should know about the specifications of the purifier size and shape. Most of the customers think that the size of the purifier can be easily fitted in every place, but it is really important to know which size can fit into the placement of your room. But the major mistake you can make while buying a purifier is that you can buy a new purifier. you think it can solve all the indoor problems, but it will create many issues, though. 

To make sure that you are buying the right purifier, the only thing you have to consider is to check the footage and its reviews by the buyers who have used it. The next thing you can do is to check the size of the room where it is going to be fitted.

If the device footage has a greater or equal sign on it, then it is a good choice for buying; otherwise, it will prove just a waste of money.

Here are the specific sizes of the purifier for buying:

For the air purifier required for the single, you can calculate the area by multiplying the length and width of the in feet and then consider it as the size of a square measurement of footage. For example, a 10′ x 20′ room = 200 sq. ft is ideal for single room fitting.

The additional step of the fitting of the purifier in a connected room like a dining table, drawing room, and T.V lounge is to combine the measurement of square footage as one. For example, a 10′ x 20′ living room = 200 sq. ft., a 10′ x 10′ dining room = 100 sq. ft., and a 15′ x 20′ kitchen = 300 sq. ft. Combining these totals together (200 + 100 + 300) equals 600 sq. ft is ideal for multiple connected rooms.

After doing these calculations, you will come to know that buying a purifier is a crucial task for different areas and different sizes. These are the specifications you should consider. 

Considering the Placement of Air Purifier

This part about the placement of the purifier is that it is the most important consideration where the purifier is being placed because it will be going to affect the working of the purifier very much. It is said that size and footage matter, but if you don’t put it in the right spot of the room, it may not work well as it is designed to work.

These are some more considerations before buying the air purifier.

Air purifiers that use a HEPA filter and/or Carbon filter depend on a fan that pulls the dirt and polluted air into it and pushes out the clean air into the environment. By outing the machine under the couch, behind the sofa, or in the front of the wall, this may block the air stream of the fan and hinder the performance of the purifier. The best place for placing the purifier is to put it 2 feet away from the wall or any object. This will give the machine to work properly by having enough space for its air stream passages.

Air cleaners that use Ionic filtration do not depend and operate with the help of a fan, but it works on the principle of ions spreading in the environment in a 360-degree rotation. In this case, if you are placing something in front of the purifier, then you will also put a hurdle in its working. The best place where it is working efficiently is the center of the room, so this is the best place for putting the purifier.

Features of the Air Purifier that should be present in it

  • There is a pre-filter present in the purifier, which helps in purifying the larger particles of dirt and dust so it may not affect the life of the purifier, and the internal purifier also does not get damaged.
  • There must be digital control of the machine because it will work more effectively than other rotators or button push purifiers.

  • The purifier must have a handle, which makes it easy to transport the machine from one place to another.
  • Just like handles, the caster is also really important as it gives balance and support while moving the machine because it will easily roll over the wheels.
  • The purifier should have disinfectant, which removes all the contamination from the air.
  • Advanced filtering processes may also remove mold, fungus, and other microbes present in the air, which may prove hazardous for human health.
  • The nightlight is also present, which helps in making the system visible in the dark.
