Why Should We Use Air Purifier?

An air purifier is an essential product for those who are suffering from respiratory-related health diseases. It filters the polluted air from the indoor air and provides healthy air into your room. There are hundreds of reasons for using air purifiers. Let’s see some reasons for using air purifiers.

Enclosed home and apartments:

The increasing number of population and the industry have lessened the space of the residential area. Some developers are not complying with the codes of the building that were written for ensuring proper safety and ventilation. The walls of our house trap gases, chemicals, and other particles. According to the EPA, indoor air becomes more polluted than the outdoor environment.

People suffering from asthma and allergies:

Both airborne particles and airborne chemicals aggravated allergies. The people who are suffering from allergies know the realities of discomfort. To get rid of allergic reactions, you should use an air purifier with ponds of activated carbon. An air purifier with HEPA filters removes airborne chemicals and airborne particles.

How Many Air Purifiers Do I Need?

Knowing the right number of air purifiers is a crucial thing. It is tough to say the required number of air purifiers for you. But we give some factors that you should remember at the time of buying air purifiers. “How many air purifiers do I need?” is a common question. The number depends on the capacity of the air purifier, the space of the floor, and the condition of the indoor air environment.

Measure the size of the flat:

You can know the required numbers of air purifiers by measuring the area of your floor. You can either set small air purifiers for each room, or you can purify the air by moving a powerful air purifier. You can use the traditional way to measure air volume, or you can use anemone meter.

Clean Air Delivery Rate of Air Purifier:

CADR is the international performance matrix of the air purifiers. The lowest number of this matrix is 0.10 micron, and the highest number is 11. You will see AHAM verified mark on the air purifier if AHAM authorities verify them. The higher the rate of clean air delivery rate, the better for you. You need fewer air purifiers if you buy air purifiers at a higher rate.

The capacity of the air purifier:

If you buy an air purifier with a higher capacity, you need fewer air purifiers and vice-versa. The capacity of the air purifier largely depends on the size of the fan and type of filter in the air purifiers.

Indoor air environment:

We and our pets are sometimes responsible for polluting the air in our room. We use different kinds of air freshener, hair, and body spray that pollutes our room environment. Dogs and birds in our house waste our room environment. If the air quality of our room is very high, we need more air purifiers.

The outdoor air environment:

The industries and vehicles pollute air severely. If we live in an industrial area or beside the highway, the air out of our room becomes very polluted. Air becomes polluted after some hours of purifying. So, we need more purifiers than generally bought in a normal environment.

We recommend breaking down your home into some specific area. Then select the numbers based on the CADR. The following recommendation will help you to choose the right number of air purifiers.

  • You need heavily activated carbon filters for open living, dining, foyer, and kitchen room of 4,200 cubic feet.
  • For a master bedroom, you need an air purifier with a True HEPA filter. You also should consider the noiseless and ability to turn off light display features when buying it.
  • If you have a basement of 2,100 cubic feet, you need another low-maintenance air purifier to prevent mold and carbon monoxide.

How To Choose An Air Purifier?

There are different kinds of air purifiers in the market. All of these have unique features and are used for purifying different kinds of gas and removing different particles. To get maximum benefits from the air purifiers, you need to focus on some important factors. Consider the following factors to get the best air purifier.

The room size:

You should buy an air purifier that can purify all air of your room. Problems happen when you choose a small-sized air purifier that fails to remove all airborne particles and airborne chemicals. Measure the size of the room to choose the right model of your favorite brands.

ACH rate:

The air change rate per hour is a crucial thing for better air conditions. The higher the ACH rate of the air purifier, the better for indoor air condition. You should buy an air purifier with a 4 to 6 ACH rating if you suffer from allergies or asthma.

Filter type:

Four types of air purifiers are very popular in the market.  HEPA, electrostatic precipitator, charged media, antibacterial, and germicidal are used for a different type of environment. If indoor air in your room is very high, you need to choose HEPA filter-based air. You should use an antibacterial and germicidal type air purifier to have pet animals and finds in your house.

CADR Rating:

Clean Air Delivery Rating or CADR indicates the quickness of the air purifying. The higher the number of the CADR of an air purifier, the faster it can purify the room’s air.
