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.

Italian man’s portable air purifier bedazzles onlookers

Deal with it. That’s the typical mentality most of the Chinese people have every time the air pollution gets worse.

But this Italian young man was apparently not happy about the status quo.

On Wednesday, he was spotted carrying a self-made air purifier, while riding on a bike in Chengdu, Sichuan Province.

According to the man, who called himself Mike, it cost him about 1,500 yuan($245) to build the device, using a home air purifier and attaching an oxygen mask to it.

Moreover, he also installed a storage battery and inverter as power supply.

According to experts, it’s possible to convert room air cleaners into portable air purifiers.

However, even if it’s technically possible to do so, experts say it is quite unlikely to achieve the same effectiveness in air filtering as a good breathing mask can do.

And even in developed countries, where the air quality is much better, an air cleaner needs to exchange the air in a room seven to eight times every hour, in order to maintain desired indoor air quality.

What to Look for When Shopping for an Air Purifier

A lot of people worry about the air they breathe. With all of the cars on the road and factories spewing out toxins, air pollution is pretty bad. What a lot of people don’t realize is that indoor air pollution can be even worse than the pollution outside.

Indoors we have to deal with things like dust, pet dander, mold spores, pollen, volatile organic compounds, fumes from cleaning products and other household chemicals, the list goes on and on. Some of the things floating around in the air inside your home can trigger allergic reactions, and some things can actually make you very sick.

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.”

Debate over whether should schools use air purifiers

With the repeat occurrence of smog in China, many parents call for installation of air purifiers in classrooms. Some parents even offered to pay for the purifiers. However it is refused by school authorities. It has caused hot debate over whether air purifiers should enter schools.

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.

What is an air purifier?

All home air purifiers are designed to help eliminate free flowing particles in the air. Although these particles are not visible to the human eye, they can trigger health problems like allergies, asthma, chemical sensitivity, headaches, and fatigue.

Air purifiers may be filter or filterless, with filterless air purifiers typically requiring less maintenance but also providing less effective filtration. Types of filterless air purifiers include electrostatic air purifiers and ionizers.

Air purifiers that use filters typically work by using a fan to pull air through a filter which is designed to capture airborne particles. The effectiveness of the air purifier depends on both the strength of the fan and the quality of the filter. The most effective filter material is HEPA (High-Efficiency Particulate Air), which removes 99.97% of particles that are 0.3 microns or larger. Complimentary technology used in the filter or unit may target specific airborne particles such as smoke, mold, or odor.

Types of Air Purifier
