BIS Certification for Air Filters for General Ventilation – IS 17570 (Part 1): 2021

BIS certification for Air Filters for general ventilation under IS 17570 (Part 1): 2021 verifies that filters used in HVAC and ventilation systems meet defined efficiency, airflow, and durability benchmarks. In India, certification is essential to ensure indoor air quality, energy efficiency, and safe operation across commercial, industrial, and residential environments.

Air filters for general ventilation are a critical component in modern infrastructure. From hospitals and shopping malls to office buildings and residential complexes, these filters play a direct role in maintaining indoor air quality. They trap dust, pollen, microorganisms, and airborne particles that can otherwise affect human health and system efficiency.

In India, where urban air pollution levels can be high, the performance of air filters becomes even more important. Poor-quality filters can lead to ineffective air purification, higher energy consumption, and faster wear and tear of HVAC systems. For example, a low-efficiency filter installed in a commercial building may allow fine particles to circulate, impacting occupant health and increasing maintenance costs.

This is why regulatory oversight exists for such products. The BIS Certification for Air Filters for general ventilation ensures that filters meet defined performance standards before entering the market. It acts as a structured validation system that evaluates whether filters can deliver consistent airflow, particle capture efficiency, and durability under operational conditions.

For manufacturers and importers, obtaining a BIS License for Air Filters for general ventilation is not just about compliance—it is about demonstrating reliability in a competitive market. For buyers and facility managers, certified filters provide assurance that the product will perform as expected in real-world environments.

Understanding BIS Certification for Air Filters for General Ventilation - IS 17570 (Part 1): 2021

Air filters are not passive components; they directly influence the efficiency of ventilation systems and the quality of air people breathe. The certification process is tailored to assess how these filters behave under airflow pressure, particle loading, and environmental conditions.

The BIS Certification for Air Filters for general ventilation evaluates several product-specific aspects:

• Filtration efficiency across different particle sizes
• Airflow resistance (pressure drop)
• Dust holding capacity
• Structural integrity under continuous operation
• Material stability over time

For example, a filter installed in a hospital ventilation system must capture fine particles without restricting airflow excessively. If the pressure drop is too high, the HVAC system consumes more energy, increasing operational costs. Certification ensures that filters strike the right balance between filtration efficiency and airflow performance.

Another critical factor is durability. Filters that degrade quickly may release trapped particles back into the air or collapse under pressure. The certification process ensures that such risks are minimized through standardized testing.

Applicable BIS Standard for Air Filters for General Ventilation - IS 17570 (Part 1): 2021

The relevant standard is IS 17570 (Part 1): 2021, which aligns with modern testing methodologies for air filtration performance.

Scope of the Standard

This standard covers:

• Air filters used in HVAC systems
• Filters for commercial, industrial, and residential ventilation
• Filters designed for particulate removal

Product Categories Covered

The standard classifies filters based on:

• Efficiency levels (coarse, medium, fine)
• Construction type (panel filters, bag filters, etc.)
• Application environments

Safety and Performance Objectives

IS 17570 (Part 1): 2021 focuses on ensuring that filters:

• Effectively capture airborne particles
• Maintain consistent airflow
• Do not degrade or release contaminants
• Operate efficiently over their service life

Design and Testing Principles

The standard emphasizes:

• Controlled airflow testing conditions
• Measurement of particle capture efficiency
• Evaluation of pressure drop across the filter
• Durability under simulated usage conditions

For instance, filters used in office buildings must maintain efficiency over extended periods without frequent replacement. The standard ensures that such performance expectations are met.

Testing Requirements as per IS 17570 (Part 1): 2021

Safety Tests
