In Duct Single Pass or Recirculation Loop Test, designed to evaluate the HVAC allergen and microbial removal capabilities of air cleaning technologies.
Airmid Healthgroup offers the In Duct Single or Multi Pass Test, designed to evaluate the allergen and microbial removal capabilities of HVAC air cleaning technologies.
This test assesses the effectiveness of devices such as furnace filters and HVAC filters in reducing airborne allergens and microorganisms within ducted systems, providing essential data for manufacturers to validate product performance.
Products That Can Be Tested for HVAC Allergen and Microbial Removal Capabilities
In Duct Impact study Schematic Diagram Allergen and Microbial Removal Capability of HVAC to assess airborne and surface pathogens and infectious aerosols.
This test is ideal for various HVAC air cleaning technologies, including:
- HVAC air cleaning devices
- HVAC filters
- Furnace filters
These products are widely used in residential, commercial, and industrial settings, particularly in environments where air quality management is critical.
Description of Assessing HVAC Allergen and Microbial Removal Capability
- System Setup: The air cleaning device is installed within a duct system. A “single pass” configuration is established by running the duct fan and ensuring a complete air exchange through the system.
- Control and Test Runs: Test runs are conducted with the selected air cleaning technology against a control setup. Multiple runs are performed in triplicate to ensure robust and repeatable results.
- Challenge Dust Introduction: A challenge dust containing microorganisms or allergens is introduced into the duct system. The dust is added downstream of the fan and upstream of the proximal sampling station over a controlled time period.
- Sampling and Measurement: Real-time air sampling is conducted at both proximal (upstream) and distal (downstream) locations relative to the air cleaning device. Sampling measures changes in microorganism or allergen levels across the system.
- Allergen Capture Analysis: The device’s ability to capture airborne allergens is quantified, and results are reported as ratios of reduction in allergen/microorganism levels across the filter and allergen capture rates relative to the initial challenge.
Benefits of Assessing HVAC Allergen and Microbial Removal Capability
- Performance Validation: Independent testing provides reliable data to substantiate claims of allergen and microbial reduction, enhancing product credibility.
- Precision and Repeatability: The standardized test protocol ensures accurate and repeatable results, critical for regulatory compliance and consumer confidence.
- Real-World Relevance: Testing replicates conditions similar to real-world HVAC system operation, ensuring practical insights into device effectiveness.
- Third-Party Validation and Market Advantages
Passing the Intra-Duct Single Pass Test enables manufacturers to label their products as independently tested by Airmid Healthgroup. This validation bolsters consumer trust and differentiates your HVAC air cleaning technologies in a competitive marketplace.
Turnaround Time
Testing is typically completed within four weeks from sample receipt, allowing manufacturers to integrate results into their product development and marketing timelines efficiently.
