Sounds good! If can afford 80-120 dollars a year for that then no need to DIY already.

If budget is lower...taobao ones one big pc can cut into 2 for the car, so one pc for the car works out to abt 8 to 10 dollars. Get the biggest and thickest pc you can find (eg 46mm)

Eg, this big piece is 50mm thick and can cut into 2 pcs. Should be able to fit the filter box that you can take out behind the glove compartment.

尺寸:433*265*50

But seriously, I think can alww the seller to customise exactly to fit your box for a slight premium. Just that I did not ask this one. This is F9 media, that's what I asked before.

Yea lor... no more HD view for a couple of weeks already I think :(

For the first few instances while I was "playing" with my new laser particle counter, I thought it was inaccurate/over-reading as I was thinking the air quality should be good nowadays for Jan. :)

Hit 34ug/m3 just now at 10am and once 40ug/m3 for 1hr peak. Still very much far from "haze" levels, but i really wonder where is the source since it's blowing NE winds.

Ok, ultra bo liao mode ON...i go dig details. :eek::s22::vijayadmin::s13:

China smog/haze mix is not the same as Indonesia biomass peat haze. I go dig details. Stay tuned.

Where there's smoke, AsiaOne YourHealth News

Mike Ives Wednesday, Jan 21, 2015

Air pollution kills around 7 million people every year, according to the World Health Organisation (WHO), accounting for one in eight deaths worldwide in 2012. The main causes of death were stroke and heart disease, followed by chronic obstructive pulmonary disease (COPD), lung cancer, and respiratory infections among children. -

It's especially bad in the Asia-Pacific region, which has a population of over 4.2bn and a high population density. China and India alone, with a combined population of around 2.7bn, are both enormous sources and victims of air pollution.

In 2010, 40 per cent of the world’s premature deaths caused by air pollution were in China, the world’s largest emitter of carbon dioxide, according to a survey published in the Lancet. The University of Hong Kong’s School of Public Health reported more than 3,000 premature deaths in the city in 2013, and the situation in many mainland Chinese cities is reckoned to be far worse.

China Pollution: Beijing Smog Hits Hazardous Levels | EcoDaily

China Pollution: Beijing Smog Hits Hazardous Levels

Posted by Eco Daily on January 20, 2015 in Environment|0 Comment | Post View: 53

Pollution has soared to hazardous levels in Beijing, reaching 20 times the limit recommended by the World Health Organisation.

Since Saturday visibility has been low and many people were seen wearing masks. Experts say car emissions and construction in cities are to blame.

Parts of China experience heavy smog periodically.

After an intense bout in Beijing last year in January, the government pledged to improve air quality.

On Wednesday, the government said it would ban the construction of new oil-refining, steel, cement and thermal power plants starting from March, state-run newspaper China Daily said.

On Thursday, levels of PM2.5 particulates, which are the most hazardous to health, rose to 568 micrograms per cubic metre. according to the US embassy.

The WHO recommends a maximum of 25 micrograms per cubic metre.


Smoking bacon’

A yellow pollution alert, the third highest in the four-tier system, has been in place since Saturday, according to the Beijing Meteorological Bureau.

Less severe pollution is also expected in Tianjin, Hebei province and parts of Shanxi and Sichuan provinces.

A government official in the south-western city of Dazhou in Sichuan Province said earlier in January that the lingering smog was caused by smoking bacon, State-run Xinhua news agency said.

Rao Bing, deputy head of Dazhou’s Environment Protection Bureau, was referring to the traditional method of preserving pork and sausages common in Sichuan.

On Sina Weibo, China’s micro-blogging site, many mocked the argument saying “smoking bacon has a long history, but smog does not”, Xinhua reported.

During previous bouts of heavy smog Chinese government officials have given other controversial explanations for smog including blaming farmers burning straw, another traditional practice.

China has also previously restricted industrial production and limited car usage in big cities.

Hong Kong woke up to grey skies and poor visibility this morning as air pollution headed towards serious levels – while Beijing enjoyed a rare blue sky day.

AQICN.org, which monitors air quality in cities around the world, measured an air quality index of 189, or “unhealthy” for the whole of Hong Kong – with readings from general monitoring stations in Central and Western, Sham Shui Po and Kwun Tong classed as “high”.

In comparison, Beijing had a break from its notoriously noxious air, recording a “moderate” AQI reading of just 57 as the capital experienced sunshine and clear skies.

The Environmental Protection Department warned that air quality could deteriorate further this afternoon as light winds struggle to disperse pollutants.

At 12pm roadside stations in Central, Causeway Bay and Mong Kok saw the worst of the poor air quality with readings classed as “very high” by the government’s air quality health index.

“It is expected that the health risk category of some general and roadside stations may reach the ‘serious’ level later today” the department said.

Levels of pollutants measured at the roadside in Central hit 10 on the AQHI. Readings above 10 are classed as serious.

The PM 2.5 reading, which measures fine suspended particulates hit 102.2 in Central, above the government’s limit of 75.

In cases of very high pollution, people with heart or respiratory conditions, children and the elderly are advised to reduce time spent outdoors and physical exertion outside to a minimum.

Pollution levels should improve tomorrow as winds strengthen and become northeasterly, according to Kong Wai, scientific officer at the Hong Kong Observatory.

Dry spell ahead may see water rationing - Singapore Environment News & Top Stories - The Straits Times



Water rationing could be one way for Singapore to deal with a predicted dry spell over the coming weeks.

Government agencies, environmental groups and representatives from the water industry yesterday held a discussion, chaired by Minister for the Environment and Water Resources Vivian Balakrishnan, in which they examined how the nation can do more to conserve and appreciate the resource.

The National Environment Agency (NEA) on Thursday said total rainfall for this month and the next is expected to be below average, due to the early onset of the dry phase of the north-east monsoon. Such weather events could increase in frequency and intensity as a probable consequence of global warming, said research scientist Erik Velasco of the Centre for Environmental Sensing and Modeling at the Singapore-MIT Alliance for Research and Technology.

To help tide the country over the upcoming dry phase, participants discussed ways to save water, including increased outreach and public education and more government incentives to help businesses adopt water-saving technology. The participants - from the public sector, water-related businesses and green groups - were taking part in the first of six Pre-Committee of Supply (COS) consultation sessions organised by the Ministry of the Environment and Water Resources. Other sessions, covering topics such as smoking and dengue, will be held until the middle of next month to seek feedback before the COS debate for the ministry, which is expected to be in the second week of March.

Dr Balakrishnan told participants: "If in 2014 we did not have the desalination and recycling plants, which were working at practically full steam during the dry spell, what do you think would have happened early last year? "The truth is, we wouldn't be talking about a water rationing exercise - it would have been a very real prospect."

Last year Singapore experienced a record-breaking dry spell that lasted from mid-January to mid-March. Last February was the country's driest month in 145 years. "Because (national water agency) PUB, in 12 years, managed to ramp up the (water) supply... we have almost taken it for granted that we have water security," Dr Balakrishnan said. He was responding to concerns raised by the participants about the possibility of public backlash, should water rationing be implemented.

The immediate past president of the Singapore Contractors Association, Mr Andrew Khng, said: "After hearing from the minister... we probably need to seriously look at (water rationing) and get ourselves ready. "Because if this dry spell is prolonged, it is not just the individual contractors who will face issues, the whole industry will be affected."

Although the NEA had said the upcoming dry period is not likely to be as bad as last year's drought, experts have warned that the haze could come earlier this year, if the dry weather in Malaysia should trigger wildfires there and winds bring the smoke to Singapore.

Assistant Professor Winston Chow of the National University of Singapore's geography department said: "Lower air quality arising from the haze might occur during the forecast dry period if other non-weather factors come into play, such as more wildfires from Peninsular Malaysia resulting in the winds transporting the smoke over." Dr Velasco agreed, saying: "The dry spell last year had triggered wildfires in Malaysia and produced moderate smoke- haze episodes in Singapore." They added, however, that Singapore is unlikely to be affected by the haze from Sumatra that occurs usually in June, as the predominant wind direction would keep it away.
