Air-purification Product Testing

In today's environment of heightened awareness around indoor air quality, manufacturers and consumers alike place greater expectation on the performance and safety of air-purification devices and materials. At Alfa Chemistry, a leading analytical and testing services provider, we offer comprehensive air-purification product testing services that span from passive materials (such as coatings or sprays) to active devices (such as air purifiers). Our aim is to help clients validate performance claims, ensure regulatory compliance, and optimize product development so that end-users can rely on safe, effective solutions.

Our testing service covers a wide spectrum of product categories:

Passive Air-Purification Products

These products purify air without powered ventilation and are widely used in construction, consumer goods, and indoor environments. Examples include:

• Photocatalytic coatings and surface treatments
• Air-purification sprays and deodorants
• Activated-carbon materials and composite purification media
• Plant-based or mineral-based purification materials
• Building-material additives designed to remove VOCs from indoor air

Active Air-Purification Devices

These products utilize mechanical, electrical, or hybrid purification mechanisms. We test:

• Residential and commercial air purifiers
• HVAC integrated purification units
• Fresh-air ventilation and energy-recovery ventilation (ERV/HRV) systems
• Portable and wearable air purifiers
• In-vehicle purifiers for automotive cabins
• HEPA filters, activated-carbon filters, composite filters, and purification cartridges

Our service scope supports the full life cycle of products, from R&D testing to pre-market certification, regulatory compliance evaluation, performance benchmarking, and ongoing quality monitoring.

We provide a broad range of test items:

Analytical instruments and technologies

Gas-Phase Pollutant and VOC Analysis

We utilize high-resolution instruments to quantify VOCs, aldehydes, and odor compounds at trace levels, including GC-MS, GC-FID, HPLC-UV, DNPH cartridge sampling systems, etc.

Particulate Matter Testing Technologies

For particle-removal efficiency and CADR measurements:

• Laser particle counters for PM0.1–PM10 measurement
• Aerosol generators for controlled particulate challenges
• Scanning mobility particle sizers (SMPS) for sub-micron particle profiling
• Optical particle sizers (OPS) for multi-size distribution verification

Microbial Analysis Platforms

We use biosafety-compliant microbial testing systems for bacterial, fungal, and viral purification performance:

• Bioaerosol chambers for controlled microbial exposure
• Culture-based CFU analysis
• qPCR detection systems for microbial quantification
• UV-C and sterilization performance evaluation platforms

Gas-Phase By-product and Ozone Measurement

• UV photometric ozone analyzers (CARB-approved methodology)
• FTIR spectrometers for multi-gas detection
• Ion mobility spectrometers (IMS) for reactive by-product monitoring

Filtration Media and Material Characterization

• SEM/EDS for surface morphology and filter-fiber structure analysis
• BET specific-surface-area analyzers for carbon and catalytic media
• Thermogravimetric analyzers (TGA) for adsorption/desorption behavior
• Dynamic adsorption test rigs for real-time gas-phase purification studies

Environmental Chamber Systems

We utilize controlled-environment test chambers that meet AHAM, EPA, and CARB requirements for temperature, humidity, and pollutant stability, ensuring consistent and comparable results.

As the demand for reliable indoor-air-quality solutions continues to grow, manufacturers and developers of air-purification products must ensure their offerings deliver on claimed performance and comply with relevant standards. Our comprehensive air-purification product testing services provide the robust data and technical support needed to validate products, differentiate them in the marketplace, and build trust with end-users. We welcome your inquiry and look forward to partnering with you to raise the bar for indoor air purification.
