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

What is a Dehumidifier?

A dehumidifier is a device that removes moisture from the air.

This section will look at the uses of dehumidifiers, how dehumidifiers work, various types of dehumidifiers, benefits of using dehumidifiers, and popular brands of dehumidifiers in India.

Uses of Dehumidifiers

A dehumidifier is an electrical appliance that reduces and maintains the level of humidity in the air, for health or comfort reasons or to eliminate musty odor and to prevent the growth of mildew by extracting water from the air.

They can be used in household, commercial, or industrial settings.

Large dehumidifiers are used in commercial buildings such as indoor ice rinks and swimming pools, as well as manufacturing plants or storage warehouses, while smaller ones are used in residential spaces to control moisture levels.

How do Dehumidifiers work?

A dehumidifier draws in moisture-filled air.

This air is passed over a cold, ‘refrigerated’ coil. The damp air condenses on the cold coil into water droplets which is then collected in a water tank.

The air is then passed over a warm coil and sent out from the dehumidifier, producing clean, dry air.

Upon first use, a dehumidifier will have to start to remove moisture that has accumulated in the wall linings, carpet and, furnishings, etc. Thus it is important to run the dehumidifier constantly for the first few weeks.

Once a healthy humidity level is reached, the dehumidifier can be used to maintain this.

Types of Dehumidifiers

There are common varieties of Dehumidifiers. They are:

Refrigerant

This type of dehumidifier uses a refrigeration process to cool a metal plate.

A fan draws in air into the device and when air passes over the coil/metal plate, the moisture condenses into water droplets, which is collected in a tank.

Desiccant

This type of dehumidifier uses materials that absorb water.

Inside the dehumidifier, a wheel consisting of desiccant turns slowly through the incoming air stream and the moisture gets trapped in the desiccant.

Electronic

This type of dehumidifier uses a Peltier heat pump to generate a cool surface for condensing the water vapor from the air. The condensed water is drained outside.

Benefits of Using Dehumidifiers

Since dehumidifiers help to control moisture levels in air, it has a number of benefits.
