What is Air Quality Index (AQI)?

The AQI is an index for reporting daily air quality. It provides you with an idea of how clean or polluted the air is and what kind of health issues can be caused by such air quality. AQI is calculated for 5 major air pollutants-ground-level ozone, particulate matter (PM), carbon monoxide, Sulphur dioxide, and nitrogen dioxide. The AQI index ranges from 0-500. When the AQI is in the range of 0-50, it means good air quality. 51-100 represents moderate air quality, 101-150 signifies unhealthy air quality for sensitive groups. AQI of 151-200 denotes unhealthy air, 201-300 denotes very unhealthy air quality, and 301-500 signifies hazardous air quality which can cause many health issues.

What is Particulate Matter (PM)

Particulate Matter (PM) which is also known as particle pollution, is a mixture of minuscule particles and liquid droplets. It is made up of a number of components like organic chemicals, metals, soil or dust particles. The size of PM can cause different health issues and PM less than 10 micrometers can pass through the human throat and nose and enter the lungs causing damage. PM2.5 denotes PM having a diameter less than 2.5 micrometers and they can be detected only through an electron microscope. These fine PM2.5 come from different sources like industries, motor vehicles, wood burning, airplanes, forest fires, volcanic eruptions, dust storms, etc. Due to their extremely small size, PM2.5 particles stay in the air for longer and can enter into human lungs and even the circulatory system. Children and people suffering from lung and/or heart diseases are more vulnerable to this dangerous PM2.5.

Considerations for Buying an Air Purifier

Air purifiers come in different shapes and sizes. It generally becomes difficult for the average customer to decide the best air purifiers for their home due to many technical features. You should consider the following factors before buying an air purifier:

ACH and CADR Ratings

It is important to check ratings like ACH (Air Changes Per Hour) and CADR (Clean Air Delivery Rate) for the air purifier. ACH ratings signify the number of times the air purifier can replace dirty air in a room with fresh and purified air on an hourly basis. Hence, an ACH rating of 4x means that the air purifier can remove the dirty air in the room and replace it with clean air 4 times per hour. Higher the ACH ratings, the better is the air purifier. CADR rating helps you understand how well an air purifier can clean the air in given room size. It gives you an objective and honest way to assess the effectiveness of the air purifier and how large an area it can handle.

Size of Purifier

Size of the purifier is an important consideration before buying them. You should calculate the total area of your room or space where you want to use the air purifier. Depending on the area, you should purchase an air purifier designed to clean the air in that area. It is always recommended to buy air purifiers that are designed to work in a larger area than the actual area of your room. This helps you to get the best performance from your air purifier.

Type of Filtration

The filtration system is the most important component of an air purifier as it cleans the air indoors by removing impurities from the air. You should consider the type of filtration system being used in the air purifier. HEPA (High-Efficiency Particulate Air) filtration is considered to be the best filtration type. HEPA filtration can remove 99.70% of all microscopic particles from the air measuring as small as 0.3 microns.

Maintenance Cost

To ensure the best performance from your air purifier, you need to maintain it regularly. Air purifiers which use HEPA or carbon filtration system will need regular filter replacements and this can increase the maintenance cost. You should also inquire with the dealer about their charges for a home visit and servicing the air purifier which will provide you a fair idea of its maintenance cost over the years. It is also important to check that the spare parts of the purifier are easily available in the market before making the purchase decision.

Noise Level

Air purifiers can be noisy. Purifiers which use HEPA or Carbon filtration system, come with a fan mechanism to draw external air into the unit. These fans can produce noise which depends on their size and speed. Most air purifiers come with different fan speeds. If you are considering of using the purifier in your bedroom or living area, the noise level is an important consideration for you. Ionic air purifiers don’t use filters which means they are usually noiseless in their operation as there are no fans installed inside the unit.

Energy Consumption

Like all other electrical appliances in your home, air purifiers also work on electrical energy. You should consider that in order to get the best results, air purifiers should be running continuously. This will help it to clean and purify the indoor air optimally. Since the air purifiers will be required to run continuously, you should consider buying an energy-efficient purifier. You can check the Energy Star ratings which represent the energy efficiency of an electrical appliance. Higher the star ratings, the more energy efficient is the air purifier. This will help you to reduce your energy consumption and electricity bills.

Manufacturer Credibility

Due to ever-growing air pollution, air purifiers have become a popular and important home appliance. Hence, many companies have started manufacturing air purifiers, considering their high demand. However, it is always recommended to buy air purifiers only from reputed and credible manufacturers. You should buy from manufacturers who have experience in manufacturing them and have a good track record. You should also check if the air purifier meets the regulatory compliances and standards prescribed by the government or other regulatory agencies.

Warranty

Before you purchase an air purifier, you should check the manufacturer’s warranty being offered on it. This will save you the trouble to get it repaired in the long run. It is important to go through the finer details of the warranty being offered like the parts covered, duration of the warranty, warranty extension terms, etc. Manufacturers who offer a warranty on their products is also an indication of the quality of their products. Hence, you should always buy air purifiers with a warranty as it is a long-term investment and not something which you will like to keep replacing regularly.

Different Types of Air Purifiers

Air purifiers use a different type of filtration system for purifying and cleaning the indoor air. The most commonly used type of filters in air purifiers are discussed below:

HEPA Filtration

HEPA purifiers have become the most popular and sought-after air purifiers. These purifiers have been known to purify air up to 99.70% by removing the most microscopic impure particles from the air. Before buying HEPA purifiers, you should ensure that you are buying a true HEPA purifier. Many brands are labeling their purifiers as “HEPA-type” or “HEPA-like” purifiers which cannot remove microscopic dirt particles from the air. They can only capture and remove particles sized 2-5 microns and this leads to a decrease in efficiency of almost 600% from the true HEPA air purifiers. Though HEPA purifiers are very efficient, they are also costlier to maintain as they require regular filter replacements.

Ionic Filtration

These air purifiers use ionic filtration system for purifying the air. They do not have filters and fan mechanism but emit charged ions in the room to attract dirt and contaminant particles. This technology causes the contaminant particles and impurities to fall down on the floor. They can remove dust, pollen mold spores, fungi, bacteria, viruses, and volatile organic compounds. These air purifiers are noiseless and do not require any filter replacement and thus cost-effective in the long run. The drawback of using iconic purifiers is that the impurities remain on the room’s floor unless they are collected using an electrostatic plate.

Carbon Filtration

Carbon filtration is a unique way of purifying the air. These filters use a special type of activated carbon consisting of millions of absorbent pores. The air purifier uses a bed of activated carbon to remove contaminants and impurities from the air by using a chemical adsorption technique. The carbon filtration system can remove impurities like smoke, chlorine, sediments, pesticides, herbicides, volatile organic compounds, etc. Purifiers working on carbon filtration system used to remove particles causing bad odor and not for removing particles and contaminants which cause health problems. This is a major limiting factor of these air purifiers. These air purifiers are low cost in maintenance and provide clean and fresh odor.

UVLight Filtration

Air purifiers using UV light filters do not use any physical filter for removing impurities from the air. It emits invisible ultraviolet light rays which help to remove the pollutants from the air. The UV light contained inside the air purifier and not released outside into the room. To ensure complete safety, these air purifiers use the UV-C band of the ultraviolet spectrum, which is safe for humans and does not result in any harmful side effects. UV light filtration air purifiers can remove bacteria, viruses, and germs. It creates a sterile environment and lasts for a long time.

Ozone Air Purifier

Some air purifiers use ozone for purifying the indoor air. To protect the residents from air contaminants and pollutants, these air purifiers release ozone into the room for purifying the air. However, there are many concerns about using ozone air purifiers. Experts have strongly advocated avoiding these purifiers as ozone can cause lung irritation, irritation in eyes, and in the respiratory system.
