Beijing plans to make the installation of air purifiers

Beijing plans to make the installation of air purifiers part of its school construction standards to tackle frequent smoggy weather in the capital, local education authorities said Thursday.

Several government departments, including the Beijing Municipal Commission of Education (BMCE), are working to draft the city’s school construction standards, which will include the installation of air purifiers, said BMCE director Xian Lianping, the Beijing Times reported Thursday.

In response to forecasts of heavy smog, Beijing issued two pollution red alerts this winter, under which all the city’s kindergartens, primary and high schools were shut down.

Xian said that the effectiveness of air purifiers in densely packed classrooms has yet to be determined, adding that it is acceptable for schools to independently install air purifiers.

“Installing purifiers in classrooms should ensure students’ safety and should also require parents’ approval,” Xian was quoted as saying.

Parents beset by hazardous smog in Beijing have repeatedly called for primary and high schools to install air purifiers in classrooms, but they have been turned down by schools saying they need approval from education authorities. Some parents even came up with plans to crowdfund air purifiers for their children’s schools, but their efforts were refused.

A small number of some well-funded kindergartens and primary schools have already installed air purification equipment in classrooms, but many more schools cannot afford it due to insufficient budgets.

Hao Xianjun, director of the Shijingshan district’s education commission, told the Beijing Times that schools would turn on their air purification systems on heavily polluted days to lower the concentration of PM2.5 – airborne particles less than 2.5 micrometers in diameter – to below 100 micrograms per cubic meter. Shijingshan Experimental Junior High School will be the first to install such a system when it constructs its new teaching building this year.

During the ongoing fourth session of the 12th Beijing Municipal Committee of the Chinese People’s Political Consultative Conference, many advisors submitted proposals to help schools deal with smog.

Pu Zhe, a member of the committee, said that education authorities should establish a special smog fund to install air purification systems in schools, introduce local regulations on which type of air purifiers to install and launch a unified purchasing platform, the Beijing Times reported.

At Thursday’s session, Xian told committee members that primary and high schools are expected to extend winter vacations and reduce summer vacations, as smog shrouds the capital more frequently in winter, Beijing-based The Mirror newspaper reported on Thursday. Currently, the winter vacation for primary and high schools in Beijing is about one month long.

Outdoor Air Purifier Makes Your Wait for the Bus 40% Less Smoggy

China’s campaign to wipe out air pollution reduced the levels of dangerous particulate matter in the air by 11 percent last year, according to the Ministry of Environment. But the country still has a long way to go before the air its citizens breathe every day can be considered healthy. Only eight out of the 74 cities surveyed met basic national air quality standards.

In the meantime, public awareness is rising. Pollution masks are hot commodities and startups making new models for indoor air purifiers are driving prices down. Now, a new invention currently being tested in Hong Kong claims it can reduce air pollution in an open outdoor space by an average of 40 percent (h/t to Techweb).

Under the prototype of the patent-pending system, air is drawn into the system from the inlet located at bottom. The air current then passes through a bag filter, which is effective in removing fine suspended particles (PM10 and PM2.5), before coming out through the Louvre overhead.

Hong Kong has been testing 2 meter-by-3 meter purification station on one of its busiest streets, queen’s Road East in Causeway Bay, since March. Sino Green tells Tech in Asia one unit costs HKD 600,000 (US$77,400 million). (Update: an earlier version of this story referenced the Techweb article that said the project cost US$10 million to develop. Sino Green has informed us that figure is not accurate.)

Air quality at the station can be monitored remotely. Further planned enhancements include smart controllers to manage operating hours more efficiently, solar panels for energy, and a mist cooling system for summer months.

Techweb says the City Air Purification System will be tested at Beijing’s Tsinghua University next. If all goes as expected, it could expand to other mainland cities in the future.

traffic-related pollution may be causing asthma

As cities grow larger and larger, so does the number of cars, motorcycles, and trucks jamming up our roadways. To anyone who’s been stuck in traffic behind an 18-wheeler spewing black smoke, it is no surprise that pollution from vehicles can irritate the nose and lungs. For people with asthma or other respiratory system diseases, the particles emitted by vehicles can lead to trouble breathing, trigger attacks, and cause serious complications such as bronchitis.  Is traffic causing child asthma?

Most of us know to keep the car windows rolled up and not to breathe in smoggy air on the highway. But for people living near major roadways, keeping the windows and doors of their homes shut may not be enough to stop the effects of pollution. Because modern homes are built to be energy-efficient, they are also more efficient at trapping pollution particles inside the home. And as most people spend 90% of their time indoors, living near a major roadway can have dire health consequences.

And it’s not just current asthma sufferers that need to be cautious.

A new report from the University of Southern California suggests that traffic-related pollution may be causing asthma in otherwise healthy children. Areas within 250 feet of a busy roadway had an increased number of children with serious complications due to asthma, including hospitalizations. The study’s authors estimated that at least 8% of childhood asthma cases were due to living near busy roadways.

While reducing the number of children exposed is a priority, unfortunately, many people cannot afford to move elsewhere. Nationwide, around 17% of all households are located within 300 feet of a highway. So what can we do to keep the harmful effects of pollution from causing illness?

Thankfully, small changes in the local environment can mean big impacts on health:

  • Surrounding homes with grass and trees can reduce traffic-related pollution in the air.
  • Using home air purifier inside homes and schools can reduce pollution particles found indoors.
  • Designating land near busy roadways for commercial development instead of residential can encourage builders to keep homes a safe distance away from traffic pollution.
  • Encouraging more people to take buses, carpool, bike, or walk can reduce the overall pollution in the air.

The classroom should be installed air purifier cited hot.

As schools in Beijing and other parts of northeastern China suspend classes because of the red alert over air pollution, many parents are demanding that air purifiers should be installed for the students.

With major pollution days becoming more frequent, students are staying home, often without supervision. Their parents say it would be better if their children were in the classroom, and that’s why schools need to install air purifiers.

“Our school bought air filters last year. We did a little fund raising, with each parent throwing in several hundred for that. We’ve already bought two air cleaners for the class, both of which are installed.”

Experts say air purifiers on the market are mostly designed for homes or offices. It still needs evaluation to know if it is useful in classrooms. Education authorities in Shanghai said they will coordinate with relating departments and work for a feasible plan.

Meanwhile, reports said a test has been held in a school in Beijing. After using the air purifier, the level of PM 2.5 in the classroom decreased, but with dozens of students in the enclosed room, the dense of CO2 has passed the healthy standards.

How to maintain air purifier?

The pre-filter (typically back cover) after using for a long time, will gather some of the dust, thus affect air inlet and air purification effect. Therefore, need to use a vacuum cleaner to suck away the dust, or use a rag to clean up, or even water to wash.
The filters,some of the filters need to be periodically exposed under sun to better maintain the purification efficiency, such as activated carbon filters.
Deodorizing filter, some brands’ odor removal filter can be water washed. Can maintain longer filter lift time by washing filters with water.

The ion generator, generally it is built-in, does not require cleaning, ion generator with good quality can , it’s efficiency are high.
4. Air purifier dust filter dust collection plates need regular cleaning, general cleaning once a week. Wash dust filter or collection plates with soap, install it after they are dry to keep the airflow smooth and sanitation.

Need to clean fan or electrode when they accumulate certain amount of dust. General maintenance every six months. Use long-haired brush to remove dust on fan or electrodes. When the air purifier is not in use, should clean it and then packed into the box, stored in a ventilated, dry place. Usually should pay attention to moisture, so as not to reduce the efficiency due to damp or damaged.
