ASHRAE Standard 145.1

ASHRAE Standard 145.1, developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), is a standard for laboratory testing methods to evaluate the performance of gas-phase air-cleaning systems. The standard outlines procedures for testing and measuring the effectiveness of these systems in removing specific gaseous contaminants from the air.

Key Aspects of ASHRAE Standard 145.1

1. Objective

   • The standard aims to provide a consistent and repeatable method for evaluating the performance of gas-phase air cleaners, ensuring that products meet specific criteria for removing airborne contaminants.

2. Scope

   • It focuses on the laboratory testing of air-cleaning devices, including sorbents and other materials designed to remove gaseous contaminants from the air in indoor environments.

3. Testing Procedures

   • The standard specifies methods for measuring the removal efficiency of air-cleaning systems for different gases.
   • It includes protocols for setting up and conducting tests, such as controlling the test environment, introducing specific concentrations of contaminants, and measuring the reduction of contaminants over time.

4. Performance Metrics

   • The standard defines key performance metrics, including removal efficiency and capacity, to help compare the effectiveness of different air-cleaning systems.

5. Applications

   • These tests are crucial for manufacturers to validate the performance claims of their products and for users to select appropriate air-cleaning systems for specific applications, such as in commercial buildings, healthcare facilities, and industrial settings.

Benefits of ASHRAE Standard 145.1
