Ultraviolet germicidal irradiation (UVGI) Air Purifiers

UVGI are used to sterilize air by passing it through germ-killing UV light. Well-designed UV purifiers are effective against bacteria and viruses.

Activated Carbon Filters

These are used to remove odour particles and volatile organic chemicals from air.

Ionizer Purifiers/Electrostatic precipitators

They use charged electrical surfaces or needles to generate electrically charged air or gas ions which cause particles to settle down on surfaces.

Ozone Purifiers

Ozone gas is used to remove gaseous pollutants and certain chemicals from the air.

Hybrid Air Purifiers

Air purifiers which combine the technologies mentioned above to produce better results are also available.

Benefits of Using Air Purifiers

Air purifiers remove a range of pollutants from the air and make it healthier for breathing. Continued exposure to air pollutants can cause diseases, allergic reactions and a variety of health problems.

Air purifiers can remove contaminants and pollutants such as dust, pollen, pet dander, bacteria, viruses mold, ragweed, dust mites, paint fumes, pesticides, and second-hand smoke.

They can be used in a variety of settings like homes, kitchens, hospitals, laboratories, factories etc to ensure the supply of clean and healthy air.

These devices are extremely useful in Indian cities which have high levels of air pollution.

Popular Brands of Air Purifiers in India

The price range of air purifiers in the Indian market varies between INR 7000 to INR 150000.

Most of these purifiers are hybrid systems that use HEPA filters, activated carbon, and UV radiation to produce clean air.

The price of the devices varies depending on technology, warranty period, brand value, features etc.

What is an Air Conditioner?

Air-conditioning is the process used to create and maintain certain levels of temperature, relative humidity and air purity, etc in indoor spaces.

Air conditioning is used to maintain a level of personal comfort or for ensuring optimum conditions for industrial activities. Devices that perform air conditioning are known as air conditioners.

Uses of Air Conditioners

Air conditioners are used in settings that require regulation of temperature, humidity etc.

This could be for personal comfort, maximizing efficiency, operating machines, health reasons, carrying out industrial activities and processes, etc

Air conditioners are used in a variety of settings like homes, cars, offices, hospitals, shops and commercial spaces, hospitals, laboratories, etc.

They are effective in any situation which requires altering the temperature and humidity or when consistent temperature levels and humidity has to be maintained.

Thus they can be used in homes during summers to ICUs in hospitals to storage facilities to name a few.

How does Air Conditioner Works?

An air conditioner in a room or a car functions by absorbing hot air in the space, processing it with the help of a refrigerant and a series of coils, and then finally rereleases cool air into the same space which provided the hot air initially.

The machine has a compressor, a condenser and an evaporator. When hot air flows over evaporator coils, the refrigerant inside absorbs heat and changes from liquid to gaseous state.

A compressor puts the gas under high pressure and creates heat.

The extra heat created by compression is evacuated to the outdoors with the help of condenser coils, and a second fan. As the gas cools, it changes back to a liquid, and the process is repeated.

Types of Air Conditioners

There are different types of air conditioners available in the market.

This section will look at these different types since a new air conditioner is an investment and so it’s important to consider which type fits one’s needs.

Window Air Conditioners

Window air conditioners are self-contained units installed on windows. Window air conditioners are very useful for apartments and single-level homes.

However, the cooling capabilities of window air conditioning units are limited due to their small size and fixed location.

Air Source Heatpumps

Air source heat pumps are effective in homes that have ductwork. The installation costs are high, but the running and maintenance costs are low.

Central Air Conditioners

Central air conditioners cool each room simultaneously and quietly.

They contain two units connected through refrigerant tubing: a condensing unit that is located outside the home and an evaporative unit that is located next to the furnace.

The condensing unit generates cool air which is propelled into the evaporative unit. The evaporative unit pushes the cool air around the home using the furnace duct system.

Ductless Air Conditioners

Ductless air conditioners, or split system or mini-split systems, are used by apartment dwellers or homeowners with no ductwork in their homes. They are made up of two small air conditioning units, connected via refrigerant tubing, that can be installed on the interior walls of homes.

Portable Air Conditioners

Portable air conditioners are single self-contained unit that can be moved into a room and placed on the floor.

Benefits of Using Air Conditioners

There are many benefits associated with the use of an air conditioner. Since these devices regulate temperature and humidity they can reduce the probability of mold and fungal growth.

They also provide great levels of personal comfort during hot, cold, or humid weather.

When used in offices and factories air conditioners can optimize the operating conditions for machines and increase the efficiency of workers.

Air conditioners help towards reducing the risk of dehydration and heatstroke during hot summer months in tropical regions like India.

These devices can help in improving sleep quality and can control the excessive growth of pests and parasites in indoor spaces.

Popular Brands of Air Conditioners in India

A very large number of air conditioners are available in the Indian market. Popular air purifier brands in include the likes of Blue Star, LG, Hitachi, Voltas, Daikin, and Whirlpool.

These brands produce a large variety of air conditioners including window, split, and central air conditioners(ACs).

The price range of air conditioners in the Indian market varies between INR 25000 to INR 50000 for split ACs, INR 20000-40000 for window ACs.

The price of the devices varies depending on tonnage, power efficiency, technology, warranty period, brand value, features etc.

Is an air purifier the same as an air conditioner?

Air purifiers eliminate particles while air conditioners control the temperature and moisture of air. AC units are not designed for air purification and air purifiers are not made for cooling the air.

Do I need an air purifier if I have air conditioning?

AC units are not designed for air purification and air purifiers are not made for cooling the air. Thus to eliminate small particulate particles, gaseous pollutants, and pathogens etc air purifiers are needed.

Do air conditioners circulate air?

In short an air conditioner does not circulate fresh air from outside into a house/room/closed space. Instead, it uses the available indoor air and circulates it.
