Breathe easy with an air purifier

Breathe easy with an air purifier

Some time ago Noida-based entrepreneur Sushmita Sinha’s son had a cough that lasted for almost a month. A worried Sinha decided to buy an air purifier. “It had a dramatic effect. Earlier, my son would lie awake at night coughing, but now he sleeps peacefully,” says Sinha. 
An air purifier can be a panacea for many. “If pollutants like pollen, dust, dust mites, mould, tobacco smoke and pet dander trigger seasonal allergies in you; if there is someone with asthma, a child with an underdeveloped immune system, a pregnant lady or a pet in the house; or you live in a construction zone, you should buy an air purifier,” says Jayati Singh, business head – air, health and wellness.
The first thing to look for in an air purifier is a high efficiency particulate air (HEPA) filter. “Buy an air purifier with a HEPA filter and not one with a HEPA-type filter,” says Marzin Shroff, chief executive officer – direct sales and senior vice president – marketing, Eureka Forbes. An activated carbon filter and microbial disinfection are other must-have features.
Also pay heed to the air purifier’s Clean Air Delivery Rate (CADR), a measure of the purified air being delivered (metre cubes per hour) by an air purifier operating at its highest speed setting. “Match the appropriate CADR to your room size,” says Mahesh Gupta, chairman, Kent RO Systems.
Buy an air purifier that is suited to your needs. According to Singh, the HEPA filter is a boon for an asthmatic, while an ozone-based purifier should be strictly avoided. ECARF certified models (a European certification meant to help allergic customers) with HEPA filters are ideal for people with allergies. A device with a pre-filter is a must for those residing in areas with heavy construction activity. For people living in places with high levels of gases, odours and pets, activated carbon works well.
If you are going to use the machine in your bedroom, buy a machine with a low level of noise. Also, buy one with adjustable speed settings so that you can turn it up to a higher setting when you are not in the room. “Purchase a machine with a slightly higher square-foot capacity than you need, so that you can run it effectively on its quieter ‘low’ setting, resulting in less noise and less energy consumption,” says Singh. A display, which shows the quality of indoor air, is a useful feature. Some air purifiers come with a humidifier, which helps maintain the right level of humidity indoors.
When choosing a manufacturer, go for one whose replaceable items such as filters will be easily available. Most air purifiers have two filters — a HEPA filter and a carbon filter — that have to be changed every six months or one year. Pay attention to the number of years of warranty provided with the machine. Prices of room purifiers can begin from Rs 9,000 and go as high as Rs 40,000. According to Shroff of Eureka Forbes, “The price depends on the room size, CADR, number of stages of filtration, and so on.”

Demand for air purifiers surges by nearly 50pc in Delhi-NCR: Survey

In the wake of poor air quality in Delhi-NCR post-Diwali, air purifier market in India has seen an increase of about 50 percent in its demand, according to an ASSOCHAM survey.

The objective of the survey is to measure the hike in demand for air purifying kits across 200 electronic and general stores in Delhi-NCR in past four days.

“There has been an explosion in demand for air purifiers which has jumped nearly 50 percent as air quality in and around Delhi has become hazardous post-Diwali festival,” said majority of electronic and general stores’ representatives selling such items.

“The demand for air purifier in India has been growing rapidly across metros in India but as the smog problem became severe in Delhi after Diwali the demand for such kits has become really huge and is likely to grow steadily,” said many of the store managers.

However, many of them expressed concern saying people very often get disappointed when it comes to installing air purifiers in their homes because of its high price. The majority of the demand for air purifiers comes from offices, industrial and commercial establishments.

As per market experts, the air purifier market in India is still in nascent stage and is estimated at about Rs 250 crore but has been growing by leaps and bounds since past one year owing to rising awareness about impact of air pollution.

“The national capital has been facing problem of haze for quite some time. Pollution, allergens and firecrackers together have further caused significant deterioration in Delhi’s air quality,” said DS Rawat, Secretary General of ASSOCHAM.

“All these factors together with growth in infrastructure development activities, growing sales of automobiles, urabnisation and industrialisation provide a lucrative market for air purifiers to enhance overall quality of air in commercial, industrial as well as residential settings across the region. Significant rise in per capita disposable income of consumers is also likely to drive air purifier sales,” added Rawat.

Outdoor air purifier project gathers dust

While the Delhi government is considering installing outdoor air purifiers at traffic intersections, it turns out that the last time the city experimented with such a project, it was left hanging for five years.

The New Delhi Municipal Council had set up an air filtering station in 2010, before the Commonwealth Games.

The purifier was installed outside Palika Bazaar in Connaught Place free of cost by a company called System Life on March 6, 2010. The machine cleaned 10,000 cubic metres of air every hour for about 18 months. The system worked by cleaning polluted air of particulate matter and gases with fabric filters, active carbon cartridges and electrostatic filters.

According to System Life India director Dhruv Chanana, the machine was operational till October 18, 2011, before being removed. “It was removed because no one wanted to accept the need to clean the air,” said Mr. Chanana, adding that had the NDMC gone ahead with more such purifiers, the pollution levels in the area would have reduced. That being said, the authorities have remained mum on the effectiveness of such a project.

Dr. P.K. Sharma, NDMC’s Medical Officer of Health, said it was a pilot project and had not received the necessary approvals to continue. “It was a free demonstration by the company. Before continuing with the project, it required clearance of the Central Pollution Control Board and the Delhi Pollution Control Committee. We are yet to receive that,” said Dr. Sharma.

95% efficiency

The air samples from the trial were analysed by three Italian scientists, including from the University of Modena. Their report was submitted to the NDMC and subsequently to the DPCC.

According to the report, a copy of which is with The Hindu , a total of 2.12 kg of particulate matter had been detained in 860 hours and the filtering efficiency of the system was 95 per cent.

The report concluded that with an “appropriate number of systems” (about 22 for Connaught Place) the air quality of an area could improve.

The DPCC, which works under the Delhi government’s Environment and Forest Department, for its part, did not make any comments on the efficiency of the system, as per a letter sent by one of its scientists to System Life on October 12, 2010. According to the letter, a copy of which is with The Hindu , the DPCC had not commented on the report “as no specific study was undertaken” by it.

Environmentalists, however, used the experience of the NDMC project to question the AAP government’s proposal to install outdoor air purifiers. Anumita Roychowdhury, the head of the Centre for Science and Environment’s air pollution and clean transportation programme, said air purifiers worked within confined environments, “but outdoor air is a complex chemistry with dynamic movement pattern”.

Home air purifier:wear it proudly to show your support for men’s health

Whatever your style of mustache, wear it proudly to show your support for men’s health during Movember!

mustache

During the month of Movember, men (“Mo Bros”) all over the world put away their razors and grow suave ‘staches to “change the face of men’s health.” Similar to the pink ribbon worn during October for breast cancer awareness, the stylish mustaches sported by Mo Bros provide a reminder of the importance of men’s health and help raise funds for cancer organizations.

Supported by the women in their lives (“Mo Sistas,” who often participate by wearing stick-on mustaches), men can pledge their commitment online and donate to several participating men’s health organizations, including the Prostate Cancer Foundation. Donors are automatically entered to win prizes, depending on the amount they raise.

Movember had its beginnings in Melbourne, Australia in 2003 with only 30 participants. The name comes from the slang “Mo” for mustache. Since then, over 1.9 million Mo Bros and Mo Sistas have registered and raised nearly $300 million dollars for cancer organizations and men’s health programs around the globe.

In addition to monetary support, Movember provides an easy way for men (and women) to raise awareness about often overlooked health issues, including prostate cancer and testicular cancer. Mustaches, in addition to being sophisticated and alluring, provide excellent conversation starters among family, friends, and even strangers! (And unlike the pink ribbon, Mo Bros don’t have to remember to pin it on every day.)

movember

The rules, from the official Movember site:

  1. Once registered at Movember.com, each Mo Bro must begin the 1st of Movember with a clean shaven face.
  2. For the entire month of Movember, each Mo Bro must grow and groom a mustache.
  3. There is to be no joining of the Mo to your side burns (that’s considered a beard).
  4. There is to be no joining of the handlebars to your chin (that’s considered a goatee).
  5. Each Mo Bro must conduct himself like a true country gentleman.

If you or someone you know is planning to participate, make sure to refer to this handy style guidewhen shaping the stache. And even if you don’t participate, don’t forget to remind the men in your life to get regular screenings and take care of their health!

During Movember,you can buy a good home air purifier for your family’s mens.

The United States has recently unveiled plans to expand monitoring of the world’s air quality

In our travels to China, we’ve seen first hand how air pollution is bringing down the overall health of the region especially the air quality in India. After all, we’ve been actively building our brand over there, for a reason – to contain the problem and help residents breathe better than ever. Apparently, we’re not alone.

The United States has recently unveiled plans to expand monitoring of the world’s air quality, in efforts to increase awareness of air pollution in foreign countries and prevent unfit air regulations from affecting U.S. citizens abroad, along with bordering countries.

The announcement was made last week by Secretary Of State John Kerry, who said that the US government will partner with the EPA (Environmental Protection Agency) to expand our preventative watch on air quality into countries like Vietnam, Mongolia and India – who has some of the worst air quality in the world.

This outreach plan comes after years of research on air pollution in China, who the US had been monitoring for a while. Since 2008, the US Embassy in China has been monitoring levels of PM 2.5 – airborne particulates that hurt human health more than any others. Although the watch was not well-received by Chinese officials, the reinforcement did pressure them into putting more focus onimplementing air quality regulations of their own.

John Kerry and the EPA hope similar results begin to happen across the board, once their new plan is put into place in other countries, around the world.

What are your thoughts? Do you appreciate the United States’ efforts to help the air quality in India and other countries? Or, do you wish our government just worry about the air quality in our own backyard? As purveyors of breathable air across the world, we’re just happy to hear about any initiatives focusing on better air quality, in general.

Home air purifier why use hepa filter?

Guangzhou Olansi has conducted testing and research on several models of home air purifiers and filters, using a specialty laser particle counter to measure the percentage of particles removed from the air. Here are the key fact you need to know about HEPA technology and its use in air purifier and HVAC filters.

Why HEPA?

High-Efficiency Particulate Air (HEPA) Filters are proven to be the most trusted filter technology on the market. The key to HEPA Filters is its tightly woven composition, making them an effective and safe solution to remove airborne particles that can aggravate:

  • Allergies
  • Athma attacks
  • Chemical sensitivity
  • Settling dust
  • Mold growth
  • Pet-related allergies and odor
  • Smoke odor
  • Illnesses linked to viruses & bacteria
  • Long term respiratory health problems

    How does HEPA work?

    HEPA Material

    HEPA is a flat, pleated sheet composed of millions of microscopic fiberglass threads, forming a complex maze which traps airborne particles.

    Because particles 0.3 microns are the weakest point of the filter’s performance, a filter is only classified as HEPA if it removes 99.97% of particles that are 0.3 microns.

     

    Three types of capture

    Interception

    As particles flow by, they are attracted and stick to nearby HEPA filter fibers.

    Impaction

    Air flows smoothly around filter fibers, but particles collide and get embedded.

    Diffusion

    Microscopic particles move erratically, increasing the likelihood of being captured by interception or impaction.

     

     

    How does HEPA compare to HVAC filtration?

    HEPA filters have the highest level of filtering available. Most home HVAC systems are not designed to handle the strain of the high resistance filtering of a HEPA filter, so an HVAC filter with a tight weave may reduce air flow and ultimately lower air quality. HVAC filters come in different MERV ratings,but even the most efficient MERV-rated HVAC filter is less efficient than an HEPA air purifier. If HEPA filtration is required, we recommend an air purifier.
