This is a comprehensiveassessment to determine if there are any issues with the indoor environmental quality.PureLiving conducts a series of test panel samplings to identify common indoor pollutants, as well as a thorough walkthrough to identify areas of concern and solutions to mitigate them.
This type of quality assessment serves a number of purposes, including efficiently gauging the environmental quality of a new renovation, making sure a space complies with national regulations (GB50325-2010, GB/T18883-2002) and international standardssuch as US EPA and WHO, and helping to identify problems that may be causing staff discomfort or complaints.
Common contaminants tested include:
Air – PM2.5, formaldehyde, TVOC, lead, benzene, radon, ammonia
Water – chlorine, lead, colony count, nitrates, heavy metals
PM2.5 AND BUILDING TIGHTNESS INVESTIGATION
In China, PM2.5 pollution is an unavoidable topic of concern.
This investigation audits a building envelope’s air tightness, HVAC system, recirculating filtration, and occupant activities to determine how much protection the building is providing from outdoor particulate pollution. PureLiving also measures carbon dioxide levels to determine whether there is a sufficient supply of fresh air.
Using a combination of handheld instruments and continuous monitors, we identify leaky windows and doorways, saturated filters and purifiers, indoor sources of dust, and the space’s PM2.5 action level: the outdoor PM2.5 level at which the interior environment is projected to surpass standards.
Mold Investigation and Testing
PureLiving is the only environmental consultancy in mainland China, Hong Kong, and India that provides mold testing, investigation, and remediation services, using international best practices.
Mold testing helps identify whether there is a mold issue and is particularly useful in cases where there might be odors, moisture, or physical health symptoms, but no signs of visible mold growth. Mold samples are collected and shipped to the US for analysis.Results determine:
1) the severity of mold growth by comparing measurements against outdoor reference and indoor control levels
2) the types of molds colonizing the area and whether they are harmful to humans (such asStachybotrys Chartarum, also known as “Toxic Black Mold”).
Mold requires oxygen, a food source (typically cellulose-based materials), the right temperature, and moisture to proliferate. The aim of a mold investigation is to identify options to limit moisture, as it is almost always the easiest factor to control.
PureLiving consultants utilize a combination of hygrometers, thermal imagery, moisture meters, borescopes, and experience to identify the source of moisture, then present options to stop the mold source and physically remove the growth.
CHEMICAL AND ODOR INVESTIGATION
A chemical and odor investigation has two purposes: identify an unknown odor and determine which chemicals are causing it.Conducting a comprehensive chemical and odor investigation establishes which chemical is leading to elevated TVOC levels and how to solve the issue.
PureLiving conducts the investigation by utilizing an advanced TVOC analysis method, which can identify over 65 different VOCs in the ambient air. This method is far more effective than a single cumulative concentration and allows a comprehensive comparison of the results with odor thresholds and reference standards to determine which chemicals occupants may be sensing.PureLiving also usesimported, real-time TVOC sensors to identify indoor sources of chemical emissions in addition to certified lab testing.
Lead and Asbestos Investigation
Lead and asbestos are materials known to cause cancer. However, their use is loosely regulated in some countries, and they are still commonly found in construction materials and older buildings.This testing identifies whether there is any lead or asbestos in the air, water, or building materials.
LEED v2009 and v4, WELL, and RESET Consultation and Testing
Achieving the high standards required by LEED, WELL, and RESET projects can be complex and overwhelming. PureLiving helps clients meet air and water quality requirements by determining and implementing practical features and improvements for a project space.We provide diagnostic air testing with real-time instruments to give instant results and can also design filtration solutions to ensure the project space complies with LEED and WELL’s stringent air quality requirements.
PureLiving conducted the first LEED v4 IAQ testing in China and is a founding member of the IAQA China Chapter. All projects in which PureLiving has been involved have achieved target certification for a 100% success rate on green certification projects.
OFFICE RE-STACKING PROJECTS
Office re-stacking projects need to not only juggle the complexities of a typical renovation but also take into consideration how to limit renovation pollutantscontaminating an occupied workspace.This type of project utilizes a variety of PureLiving services to ensure that the emissions created during renovation do not enter the occupied workspace.
PureLiving’s Pure-Qi ceiling-mounted air purifiers are modular, highly customizable systems that come pre-installed with polypropylene particulate filter media that is capable of removing > 98% of particulates – including smoke, PM2.5, and microbes – on a single pass.
Formaldehyde, Odor and Chemical Reduction
Pure-Qi purifiers can also be fitted with our proprietary Multifunctional High-performance Catalytic Cleaning (MHCC) potassium-impregnated carbon media, which have been proven to remove up to >99% formaldehyde and >98% of overall chemical pollutants (TVOC) within an hour.
We also offer photocatalytic oxidation treatment (PCO) for spaces where chemical emissions are significantly high and need to be brought down immediately; from our experience, treatment generally has an immediate effect of 40-90% reduction in levels. Photocatalytic oxidization is a type of remediation where a chemical (typically titanium dioxide) is vaporized and applied to furniture, walls, and floors in a room with high levels of odor or VOCs. This substance weakens the carbon bonds in the VOCs, breaking up these bonds into smaller compounds over and over again until only carbon dioxide and water (safer substances) are left behind. Titanium dioxide is non-toxic and is commonly used in food additives. The remediation process leaves behind a clear layer which continues to inhibit gas release and is antimicrobial as well. This oxidization process works better with light (artificial or natural sunlight), but also works (though at approximately 30-50% effectiveness) in darkness.
In China, it is a common occurrence for maintenance teams and landlords to overlook the severity of mold issues and simply paint over visible growth. This “Band-aid” solution is deceptive and potentially dangerous because contaminants are still present in the occupied space and can exacerbate or lead to the development of allergies. PureLiving provides end-to-end mold removal service in accordance with the ANSI/IICRC S520 Professional Mold Remediation Standard.
We incorporate a combination of products, services, and techniques to:
1) stop the source of moisture leading to perpetual mold growth and
2) physically remove mold spores and structures to limit occupant exposure and thus adverse health effects.
Waterproofing, flashing installation, fixing plumbing and draining leaks, dehumidification systems, etc.
Cross-containment barrier setup, structural removal of porous contaminated materials, physical removal of spores on non-porous surfaces via HEPA vacuuming, deactivate remnant spores utilizing aerosolized disinfectants, prevent future regrowth by applying inhibitors coatings
PureLiving offers a variety of point-of-use and point-of-entry water filtration systems that are in conformance with NSF/ANSI 42 and 53 water treatment standards to provide safe water for occupants.
PureLiving provides asbestos inspections to identify which asbestos-containing materials (ACM) are harmful and require removal and which materials can remain in buildings. We also provide professional abatement services to physically remove/encapsulate friable materials in contained environments to prevent contamination into occupied spaces.

Which Monitor to Use?
Grade A stands for Professional Grade monitors, designed to be used in clean rooms, factories, hospitals, etc. They are high end monitors equivalent to the top of the market handheld sensors available today.
Grade B stands for Building Grade monitors. These monitors are perfect for RESET projects, being able to maintain high quality data while being more budget friendly.
Grade C stands for Consumer Grade monitors. There are monitors that do not quite hit the standard for Grade B, but are accurate enough for consumer use.
Only Grade A and B monitors can be used for RESET Air Certified projects.
