The environment of the Earth is experiencing drastic changes due to various types of pollution. The future will be darker if necessary steps are not taken to solve the problems related to pollution. For the Earth’s bright future, one must strive to conserve the environment. Air pollution has become a serious concern, and every human should take measures for preventing it, however small the measure might be. It is upsetting that humans cause a majority of air pollution which is adversely affecting our health.

Types of Air Purifiers in India :

1.Carbon Filtration: The carbon filter is often called as an activated carbon filter. It keeps the home healthier and cleaner. It is activated carbon. It is made very porous so that a single gram of it may have a surface area of 500m² or more. A large number of contaminants and allergens are absorbed by this filter over a larger surface area. It is also compact.

2. Ionic Air Purifier: The Ionic air purifier is a new modern way of purifying the air. Around ion generators, these machines are constructed. Its a  steady source of negatively charged ions is sent by the ionic generator. With a positively charged ions, they, in turn, attract airborne dust, other debris, and allergen particles. The exchange between these particles and the ions modifies them until they become heavy enough to stay airborne.

3. UV Air Purifier:   You must be very familiar with UV light, but you may not be aware of its feature of creating a healthier atmosphere inside the home. For killing the bacteria in the air as well as other types of pathogens which may be harmful, electromagnetic radiation is leveraged by the UV air purifiers. For handling the issues in a home that are caused by viruses, yeast, and mold, the UV air purifiers are reliable.

4.Ozone Air Purifier: Ozone is an important feature of the Earth’s atmosphere. One would fall victim to the harsh Ultraviolet Rays of the Sun without the ozone layer. For protecting the residents from various types of contaminants in the air, many air purifiers use ozone. These purifiers work by effectively pumping ozone into the indoor air. Ozone oxidizes anything it touches. If ozone is exposed to iron, the iron will become rusty.

5. HEPA Air Purifier: HEPA air purifiers have become most famous in this modern era. But it was actually invented in the 50s when a solution for small radioactive particles was needed by the US Atomic Energy Commission. Thus, HEPA (High-Efficiency Particulate Arresting) filters were produced. These air purifiers are used in residential homes, beauty salons and hospitals. They are gaining a lot of popularity. Even the manufacturers in the market are tagging their models of air purifiers as ‘True HEPA’ for assuring the customers that those air purifiers have original HEPA technology and not an abridged version.

Things you should consider before buying an Air Purifier

1. Air-exchange rate: The amount of air an air purifier is capable of passing through its system in 60 seconds is called the maximum air-exchange rate. Compared to the air purifiers with lower air-exchange rates, the air purifiers with higher maximum air-exchange rates will clean the air faster.

2. Filter-change alert: The Filter-change alert of an air purifier lets you know about the time to change the filter. Some of them operate on a regular basis, while others base this information on the current condition of the filter

3. Dust sensor: Very few air purifiers consist of automatic sensors for detecting the pollution level of air. Without any manual intervention, they have the ability to adjust the cleaning speed of the air purifier. Thus, users are provided with less precise control over noise levels and energy consumption.

4. Fan speeds: There are multiple fan speeds in most of the air purifiers. They adjust the speed at which the air cycles through the air purifier. The noise is directly proportional to the higher fan speeds of an air purifier.

5.Large capacity: There are more affordable options if one needs an air purifier for a relatively smaller space. For larger rooms, one needs to purchase a more costly model of air purifier which has a great capacity of covering more areas.

6.A reasonable cost of ownership: The filters of most of the air purifiers have to replaced annually or periodically in certain cases. There is more than one filter in some models of air purifiers while others have a permanent filter installed in them, which needs to vacuum periodically instead of replacing.
