Different technologies and types of air purifiers have various advantages and drawbacks and they have varying levels of effectiveness against different types of pollutants.
Types of Air Purifiers
There are different types of air purifiers available in the market. This section will look at these different types.
HEPA Filter using Air Purifiers
These purifiers use a HEPA filter that can remove atleast 99.97% of particulate pollutants that are equal to or above 0.3 microns in diameter. They are highly effective against particulate air pollutants.
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 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.

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:
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.
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.
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.
Reduces Mould and Fungal Growth
High levels of moisture encourage the growth of a variety of molds and fungi which can cause diseases, allergies, and discomfort. Dehumidifiers can help in controlling mold and fungal growth.
Extremely Useful During Monsoons
Dehumidifiers can come in very handy during monsoon season. It can control humidity levels in homes, offices, factories, etc.
Dehumidifiers May Make Breathing Easy
Moist air becomes heavier and is often more difficult to breathe. High-humidity environments can be difficult for people who have asthma/breathing difficulties.
A dehumidifier can make the effort to breathe in and out easier on the lungs.
Popular Brands of Dehumidifiers in India
Popular air purifier brands include the likes of ABS, Kedsum, Honeywell, Sharp and Powerpye. These brands produce a large variety of purifiers.
