Air Purifier CADR and Environmental Chamber Test Solution
Overview
Air purifiers, fresh air purification systems, air disinfection devices and filter materials require stable and repeatable performance evaluation. A CADR and environmental chamber test laboratory should provide controlled test volume, low background concentration, stable temperature and humidity, pollutant generation, uniform mixing, sampling and automatic data recording.
Shenzhen LSKFT Testing Instruments Co., Ltd. supplies customized air purifier CADR test chambers, environmental test chambers and data acquisition systems for manufacturers and testing laboratories. The chamber volume, control range, sampling system and software functions can be configured according to the actual testing method and product size.
Applicable Products
- Household and commercial air purifiers;
- Fresh air purification systems and air disinfection devices;
- HEPA filters, activated carbon filters and composite filter materials;
- Vehicle air purifiers and air treatment modules.
Main System Modules
| Module | Function | Key Requirements |
| Environmental chamber | Provides a stable test space | Sealing, low background concentration, easy-to-clean inner surface |
| Temperature and humidity control | Controls test conditions | Stable temperature and humidity range, low fluctuation |
| Pollutant generation and mixing | Builds initial concentration | Uniform mixing, stable concentration and repeatable decay curve |
| Sampling and monitoring | Collects concentration data | Multi-point sampling, instrument interfaces and automatic recording |
| Software system | Stores data and generates reports | Sample information, test condition, curves, results and export function |
Laboratory Design Considerations
The laboratory should reduce external particle interference and maintain stable ambient conditions around the test chamber. For 30m³ or larger chambers, structure strength, door sealing, inner circulation, sampling port arrangement and maintenance space must be considered during the design stage. If both particulate matter and gaseous pollutants need to be tested, the pollutant generation method, safety exhaust and sensor interfaces should be planned in advance.
Automation and Reporting
An automated CADR test system can record temperature, humidity, pollutant concentration, test duration, purifier operating state and decay curves. For manufacturers, this reduces manual recording errors and improves R&D efficiency. For testing laboratories, a complete data record is useful for internal quality management and report review.
