With pollution levels reaching alarming levels air purifiers have become hit among consumers, but are all of them equally good?

Air purifier reduces air contamination inside the house along with indoor pollution. Hence, air filters with good High-Efficiency Particulate Air (HEPA) efficiency are more effective in combating indoor pollution.

A HEPA filter sucks airborne contaminants and pushes out clean, fresh air.

Here are some high-quality Air purifiers with HEPA filters which people can use:

–Dyson Pure HotCool air purifier

The Dyson air purifiers contain two different types of filters – a pair of H-13 grade glass borosilicate HEPA filters and a pair of activated carbon filters.

The very fine pre-filter layer that traps the larger particles before the air passes through the HEPA filter.

Priced at Rs 54,900, Dyson Pure HotCool delivers fast and even room heating in winter, powerful cooling in summer and efficient purification through all seasons.

The machine automatically detects airborne particles and gases, and simultaneously reports to the new LCD screen and Dyson Link app in real-time, encouraging wellbeing and maintaining comfort levels in the home.

“Our latest machine goes beyond standard tests. It heats and cools you quickly and effectively – while always purifying the whole room,” Sam Bernard, Global Category Director, Environmental Control, Dyson, said in a statement.

–Samsung’s air purifier AX7000.

The Samsung air purifiers build on with a thick HEPA filter and an activated carbon filter.

The HEPA Filter also have anti-allergen coating which gives double protection.

AX7000 provides faster purification through advanced PM2.5 filters.

Available for Rs 41,990, AX7000 gives faster air purification with a higher Clean Air Delivery Rate (CADR) and covers a large area with the three-way airflow.

The four-step air filtration provides double protection and results in a fresh and pollution-free.

–Eureka Forbes Aeroguard AP 700 DX
Aeroguard AP 700 DX comes with six-stage filtration. It removes large particles such as dust, hair, pet danders and fibres. It also removes dust particles holding harmful dust that settles in lungs.

Aeroguard AP 700 DX with HEPA filter is capable of removing up to 99.97 per cent of micro-particles, such as particulate matter (PM 2.5 and 10), fine dust, pollen and mould spores. It costs up to Rs 19,990.

–Philips Mario (AC3821)

Priced at Rs 37,995, Philips Mario (AC3821) is a 2-in-1 device that not just purifies the air but also maintains an optimum humidity in the room.

With HEPA filters, it removes pollutants and allergens as small as 0.003um from the air, 800 times smaller than PM 2.5, apart from removing dust, smoke and pet dander.

It also offers a smart humidity sensor that enables the consumer to precisely manage the humidity level of the room and shuts off automatically to prevent over-humidification, hence, making indoor air healthy and comfortable to breathe.

–SHARP FU-A28E-W Air Purifier

SHARP has also air purifiers which have HEPA filter that are instrumental in combating air pollution.

Sharp FU-A28E-W uses Plasmacluster Ion Technology, which deactivates suspended airborne mould, viruses, dust mite allergens and bacteria. Priced at Rs 6,700. (IANS)

Climate Change Would Affect Health Of Indian Children: Lancet

Climate change would hit health of Indian children hard, says study by Lancet

Children in India will be particularly vulnerable to the ill effects of climate change such as worsening air quality, higher food prices and rise in infectious diseases, warns a new study published in the journal The Lancet.

Climatic suitability for the Vibrio bacteria that cause cholera is rising three per cent a year in India since the early 1980s, said the report.

“With its huge population and high rates of healthcare inequality, poverty, and malnutrition, few countries are likely to suffer from the health effects of climate change as much as India,” said study co-author Poornima Prabhakaran from the Public Health Foundation of India.

“Diarrhoeal infections, a major cause of child mortality, will spread into new areas, whilst deadly heatwaves, similar to the one in 2015 that killed thousands of people in India, could soon become the norm,” Prabhakaran said.

Through adolescence and into adulthood, a child born today will be breathing more toxic air, driven by the fossil fuels and made worse by rising temperatures.

This is especially damaging to young people as their lungs are still developing, so polluted air takes a great toll, contributing to reduced lung function, worsening asthma, and increasing the risk of heart attacks and stroke.

Later in life, a child born today will face increased risk from severe floods, prolonged droughts, and wildfires.

Most countries have experienced an increase in people exposed to wildfires since 2001-2004 with a financial toll per person 48 times larger than flooding.

India alone saw an increase of more than 21 million exposures, and China around 17 million, resulting in direct deaths and respiratory illness as well as loss of homes, said the report.

“Over the past two decades, the Government of India has launched many initiatives and programmes to address a variety of diseases and risk factors. But this report shows that the public health gains achieved over the past 50 years could soon be reversed by the changing climate,” Prabhakaran said.

The “Lancet Countdown on Health and Climate Change” is a yearly analysis tracking progress across 41 key indicators, demonstrating what action to meet Paris Agreement targets — or business as usual — means for human health.

The project is a collaboration between 120 experts from 35 institutions including the World Health Organisation (WHO), World Bank, University College London, and Tsinghua University.

For the world to meet its UN climate goals and protect the health of the next generation, the energy landscape will have to change drastically, the report warns.

Nothing short of a 7.4 per cent year-on-year cut in fossil CO2 emissions from 2019 to 2050 will limit global warming to the more ambitious goal of 1.5 degree Celsius, said the report. If the world follows a business-as-usual pathway, with high carbon emissions and climate change continuing at the current rate, a child born today will face a world on average over 4 degree Celsius warmer by their 71st birthday, threatening their health at every stage of their lives.
