• Over the years, air pollution in India has become quite a serious issue.
  • In the year 2014, World Health Organization has ranked Delhi as the most polluted among 1,600 cities across the world, worse than Beijing.
  • As per the data provided by WHO, Indian Cities of Delhi, Patna, Gwalior and Raipur have the highest concentration of PM 2.5 particulate.
  • 13 Indian Cities have made it to the list of “Top 20 cities in the world with the highest levels of PM 2.5”
  • The national capital leads the pack with more than 153 micrograms per cubic meter.
  • The major sources contributing to the air-pollution are wood and biomass burning, Industries, rising infrastructure projects, fuel adulteration, vehicle emission and traffic congestion etc.
  • As per World Health Organization (WHO), Air pollution is the world's biggest environmental health risk.
  • The indoor Air is likely to be 4 to 5 times more polluted that air outside, which means a bigger risk as most of the individuals spend around 80 to 90% of time indoors.
Indoor Pollutants Source
Carbon monoxide Cooking Fuel/Tobacco combustion
Fine particles Cooking Fuel/Tobacco combustion, cleaning, fumes from cooking oil
Nitrogen oxides Cooking Fuel combustion
Volatile and semi-volatile organic compounds Cooking Fuel/tobacco combustion, furnishings, construction materials, fumes from cooking, consumer products
Aldehydes Furnishing, construction materials, cooking
Dust Carpets, furnishings and dust from outside
Asbestos Wear or demolition of construction materials
Lead Wear of painted surfaces
Biological pollutants Moist areas, ventilation systems, furnishings
Cigarette and cooking Smoke Cooking & Tobacco consumption
Hair Pets & Human
Stale Air Air-Conditioners
Foul Odor/Methane Cooking, Air-Conditioners and defecation
  • As per World Health Organization, close to 1.3 million Indians die every year due to adverse effects of the indoor air pollution.
  • Air pollution is a leading risk factor for diseases, like ischemia, myocardial infarction, asthma, stroke, chronic obstructive pulmonary disease and lung cancer etc. 
  • Lung cancer deaths due to air pollution have increased significantly since 2005. According to WHO report, around 30% of all lung cancer deaths can be attributed to the joint effects of household and ambient air pollution.
  • Indoor air pollution is more hazardous to health as it is released in close proximity to people.
  • The Ill effects may arise after just a single exposure as well as repeated exposure, and can range from irritation of the eyes, nose, and throat, to headaches, dizziness, and fatigue.
  • Longer exposure to indoor air pollutants can lead to serious health issues and even Premature Death.
Indoor Pollutants Effects
Carbon monoxide Long term exposure causes suffocation and uneasiness.
Fine particles (PM 2.5) Long term exposure causes Allergy, Asthma & lung cancer
Volatile and semi-volatile organic compounds Carcinogen in nature, causes cancer.
Dust Allergy and Asthma
Asbestos Carcinogen in nature, causes cancer.
Lead Lead poisoning.
Biological pollutants Cold & Allergy
Cigarette and cooking Smoke Allergy, Asthma and Lung cancer.
Hair Allergy & Asthma
Stale Air Suffocation and uneasiness
Foul Odor/Methane Suffocation and uneasiness

Particulate matter, or PM, is the term for particles found in the air, including dust, dirt, soot, smoke, and liquid droplets. Particles less than 2.5 micrometers in diameter (PM2.5) are referred to as "fine" particles and pose greatest health risks. All types of combustion activities (motor vehicles, power plants, wood burning, etc.) and certain industrial processes are the main source for PM 2.5, particulate.

Because of their small size (approximately 1/30th the average width of a human hair), fine particles can lodge deeply into the lungs.

Due to increased concentration of PM 2.5 particulate matter, every individual in the country is at a higher risk of experiencing PM2.5 related health effects. One group at high risk is active children because they often spend a lot of time playing outdoors and their bodies are still developing. In addition, oftentimes the elderly population are at risk. People of all ages who are active outdoors are at increased risk because, during physical activity, PM2.5 penetrates deeper into the parts of the lungs that are more vulnerable to injury.

As visionaries of the future and healthy living, KENT, introduced the revolutionary and innovative 4 stage filtration process which effectively removes 99.97% of particles, less than 0.3 microns in diameter.

First Stage: Pre-filter

Pre-filter installed in KENT HEPA room air-purifiers traps and removes large particulate matter like Dust Particles, Cobwebs, Human/Pet Hair, Debris and Sand Particles to increase life of HEPA filter.

Second Stage: Specially treated Carbon Filter

A honeycomb structure with specially activated carbon arrests pollutants and harmful gases. It also helps in increasing life of the filter and to record best results from the filter.

Third Stage: Antibacterial Coated HEPA Filter

The Anti-bacterial coated HEPA filter, developed with superior Japanese technology, traps SPM (suspended particulate matter) as small as 0.3 microns with 99.97% efficiency.

Fourth Stage: Ionizer

An in-built Ionizer reduces the amount of particulates that enter your lungs by dispersing electrically charged ions. The electrically charged ions are believed to produce biochemical reactions that increase levels of the mood chemical serotonin, helping to alleviate depression, relieve stress and boost energy.

  • HEPA (High Efficiency Particulate Arrestor) dust collection technology from Japan.
  • HEPA filter with antibacterial coating.
  • High-efficiency removal of PM 2.5 particulate matter.
  • Intelligent air quality monitoring.
  • Filter change indicator.
  • Low noise operations.
  • User-friendly functional design, safe and convenient for use.
  • High purifying capacity, purifies air in the room instantly.
