NEW YORK – New technology has been deployed on the streets of the Big Apple to better monitor air quality.
CBS2’s Leah Mishkin has more on how data will be collected block by block.
It may look like your average car, but the Aclima vehicle is designed to measure air quality while driving.
How does it work? The air enters through an opening near the side door and reaches the trunk where the technology is located.
“This kind of sensors are typically the size of trailers, very expensive, very large, very difficult to implement. So what we’ve done is miniaturize that technology,” said Aclima CEO and co-founder Davida Herzl.
It makes it possible to collect data block by block.
“A child coming out of a school playground. A residential complex that could be located next to a highway, like the Great Deegan,” said Basil Seggos, commissioner of the state Department of Environmental Conservation.
That type of micro-information is what the DEC Commissioner says the agency had not been able to collect until now through this partnership.
The data came from stationary air monitoring sources.
“We will be able to spend those dollars on improvements in mass transportation, improvements in street quality, improvements in street tree coverage,” Seggos said.
Seggos said the California company’s cars are already out in the Bronx, northern Manhattan, Albany and Buffalo.
The state is targeting disadvantaged areas known for poor air quality, something a South Bronx resident said she has seen on her own in her neighborhood.
“My cousins have some of the most chronic asthma, that they had to have a lot of medication, constantly on ibuterol, trips to the emergency room, the emergency room, to the point where they actually left New York City,” said a woman named Melissa. “This data will really bring that point home and hold everyone accountable.”
The cars will measure air quality in a total of 10 communities across the state.

Do HEPA filters remove VOCs?
VOCs, because they are gases, are about 1000 times smaller than what HEPA filters can capture. In addition, VOCs do not adhere to HEPA filters, so they are not capable of handling anything that may be present in the air. See the article : Food Security. As a result, HEPA filters are not a good choice if you are looking for an air purifier for VOC.
What kind of air filter removes VOCs? For consumers looking for a way to remove VOCs in their homes and offices, Kroll adds, “air purification using activated carbon filters, a proven technology that does not rely on chemical reactions, is still the way to go.”
How do you remove VOCs from your home?
You can get rid of VOCs and let some fresh air into your home by opening a window, using the exhaust fan in your kitchen or bathroom or having a mechanical fan installed. Heat or energy recovery fans remove old indoor air and draw the same amount of fresh air into your home.

Homemade Cleaners Because so many commercially available cleaning products contain VOCs, it is wise (and cheaper) to make your own cleaners at home. Try this simple recipe for a universal cleaner: 1/2 cup white vinegar. 1/4 cup baking powder.
What removes VOCs?
Activated carbon air purifiers and filters can remove any VOC concentration from the air in an enclosed space, such as your home, office, workplace, or indoor indoor space. They work by chemically attracting organic pollutants to be absorbed by the carbon inside.
How do you filter out VOCs?
Unlike particles, gaseous pollutants such as VOCs cannot be captured by ordinary HEPA filters. Instead, use an activated carbon filter to remove these chemicals.
How do you filter VOCs?

Do air filters reduce VOCs?
The good news is that activated carbon filter air purifiers with activated carbon filters are able to remove VOCs from the air. This is also a good thing because concentrations of VOCs can be up to 10 times higher indoors according to the EPA.
Do air purifiers work for VOCs?
If you are wondering how to remove odors, VOCs or gases from household chemicals and other sources from the air at home, consider an air purifier with an activated carbon filter. Combine that with reducing exposure, and your home will smell as fresh as it looks – and have cleaner, healthier air.
What is the best way to eliminate VOCs from your home?
Increase ventilation Centers with central air and heat can install special air filters designed to reduce VOC levels indoors, and many buildings can benefit from periodic window opening to allow fresh air circulation. Before opening windows, however, it is important to check the outdoor air quality.
How do you remove VOCs from air?
Activated carbon air purifiers and filters can remove any VOC concentration from the air in an enclosed space, such as your home, office, workplace, or indoor indoor space. They work by chemically attracting organic pollutants to be absorbed by the carbon inside.
Are VOC sensors accurate?
Due to the relative nature of the sensor, the VOC sensor cannot define an accuracy tolerance. By definition, accuracy is the variation from an absolute measurement. Since the VOC sensor uses ABC logic, there is no absolute measurement.
Can you measure VOCs? The two most commonly used methods for statistical VOC analysis are flame ionization detection and photoionization detection. Both methods measure the number of chemicals in the air based on the assumption that most organic vapors produce positively charged carbon ions when they burn (1).

How do you test for VOCs?
VOC testing can be performed in two main ways:
- The use of an onsite PID (photo-ionizing detector) meter for total real-time VOC (tVOCs) levels
- The use of sorbent tubes or air capture devices for laboratory analysis (usually GCMS) or summa containers and regulators to target a wide range of compounds with the EPA method TO-15.

Which air quality index is best?
Think of AQI as a scale that goes from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 or less represents good air quality, while an AQI value above 300 represents hazardous air quality.
What is the difference between EPA AQI and PurpleAir AQI?
Empirical studies have found that PurpleAir monitors tend to give greater AQI values than EPA monitors like those used by AirNow (see the end of this article for more on why) when measuring wood smoke . To correct for this, PurpleAir provides several correction factors that you can use to get a better estimate.
