How to Select an Air Purifier for my Home?

Pollution is not only an issue for out outdoors as the constant weather and other common reasons that are increasing globally causes allergic diseases. Along with taking care of the environmental pollution, we have to take care of our indoors as well–or else they are prone to cause respiratory allergies such as dust mites, pollens, pet allergies, and the cockroach allergen.
Dust mites, however, are micro creatures that are hardly visible by our eyes so it is better to have a solution for such unseen particles to prevent other any lungs or inhaling issues. An Air Purifier could possibly minimize these pollutants.
In this blog, we are sharing some key features of the air purifier that will guide you to getting according to your home.

The Key factors include

Room Size

  • Knowing the room size is one of the important factors as then, you can get the purifier accordingly. The size also determines the through of the air purifier. Small size is incapable of purifying the required amount of the air level due to its small filters. The minimum dimensions are 4.92 x 4.92 x 5.31 (the portable one).
  • To avoid any kind of inconvenience, make sure that you have the proper measurements of your room. For placing it in the living room, you will need a large purifier.

CDAR Rating

  •  Clean Air Delivery Rate (CDAR) is the rating that shows the delivery of the air purifier at the maximum speed. It calculates the air purified each minute per cubic foot.
  •  Every purifier has a different CADR value for different kinds of particles like smoke and pollens.
    The purifiers that have a high CADR rating are more efficient and suitable for large places.

ACH Rating

• Air change rate per hour (ACR) shows the number of times the purifier filters the air every hour. It also depends upon the size of the area, as the size increases, the number of ACH decreases and increases.
• On average, the efficient air purifier is capable of performing 5 to 6 changes per hour.

Noise Level

  • A purifier uses a fan that helps to draw air into the body of the air purifier that may cause noise. This is basically the vibration that is produced by the purifier while filtering the air.
  • The noise pressure and noise level is measured in dB the noise greater than 50db could make it difficult listening to normal conversation. Whereas 70dB can cause severe damage to the hearing.
  • The small-sized air purifier will take a lot more power and at its large speed for working in a large room so does the noise will be. That also proves that it works at its full speed.

Maintenance and Service Cost

  • It is important to maintain and have a regular service of your purifier for its working condition. The core maintenance is for HEPA, filters, and carbon filters. They must be changed and replaced from time to time.
  •  The cost varies for each type of purifier while some are relatively expensive.
    It is better to have a clear idea before making a final purchase for your home for the cost of running smoothly.

How does an Air Purifier Works?

The air purifiers help to filter the air of pollution (the tiny particles that are not visible) like pollens, mold spores, and dust. Along with that, there are gases and smoke coming from different sources.
An air purifier is a device that has a fan and a motor that sucks the air from outside and produces clean and filtered air by removing the impurities.

Kinds of Air Purifier

Air purifiers are of different kinds, colors. sizes and shapes. They are further categorized according to their filter types so you can use them according to the kind of pollution that you need to handle.
The main type of air purifier includes

1. HEPA Air Purifier

The high-efficiency particulate air (HEPA) is a kind of filter that has multi-layers of synthetic fibers. The HEPA filters are capable of removing particles of air that includes

  •  Dander
  • Pollen
  •  Dust
  •  Mold
  •  Pet Hair

The standard that the HEPA filter has is larger than 0.3 microns that can remove 99.7% of the air.
The HEPA filters are also capable of removing bacteria and viruses, but they can not remove gaseous pollutants from the air.

2. Activated Carbon Air Purifier

It consists of a carbon filter made of activated carbon. These are specified for removing the gases, odors, and smoke. The activated carbon has thousands of small particles
The activated carbon purifier consists of a filter made of activated carbon. These purifiers consist of tiny pores in a large amount.
The activated carbon filters’ absorbing ability. When the air passes through these pores, pollutants like chemical emissions, smoke, and odors are captured due to chemical bonding. Activated carbon also absorbs formaldehyde and chemicals used in surface cleaning items.

Ionic Air Purifier

An ionic air purifier removes dust and smoke particles by emitting negative ions which are negatively charged oxygen molecules. These ions stick to the pollutants in the air and make them heavier, as a result, these particles cannot stay in the air and stick to the other surfaces.

Some ionic purifiers also have charged metal plates, these plates attract charged particles and capture them so they cannot move with the air.

1. UV Air Purifier

UV air purifiers use UV lamps to produce ultraviolet light. These lamps produce UV-C light which can damage the DNA of living microbes like bacteria and viruses. As a result, these microbes stop their working and become harmless to human beings.

Ultraviolet rays have no effects on dust particles and gases included in the polluted air. Therefore UV air purifiers are usually fitted in combination with another type of filter like a HEPA filter to remove solid pollutants.

2. Central Air Purifier

If you have a central heating or cooling system at home, a central air purifier can be attached to the system to clean the air of the entire house. Central air purifiers are fitted with different types of filters in combination so that they can perform better against all types of pollutants.
