Air Purifier Standards in India: BIS and Certifications

In December 2023, India took a significant step toward ensuring air purifier quality when the Bureau of Indian Standards (BIS) made certification mandatory. This comprehensive guide explains everything about air purifier standards in India, covering both BIS and Quality Council of India (QCI) certifications. Whether you’re a consumer wanting to verify product authenticity or a manufacturer seeking compliance, this guide provides all the essential information you need.

Understanding Air Purifier Standards in India: The 2023 BIS Mandate

In December 2023, the Bureau of Indian Standards (BIS) implemented the first mandatory certification standards for air purifiers in India, marking a significant shift in the industry’s regulatory landscape. This development established clear guidelines for air purifier performance and quality assessment.

The Bureau of Indian Standards functions as India’s national standards body, responsible for developing and implementing quality standards across various products and services. With air pollution becoming a pressing concern in Indian cities, the need for standardized air purifier performance metrics became essential.

The newly implemented standard, officially known as IS 17899:2022, became mandatory from December 12, 2023. According to P.K. Tiwari, Director General of BIS, “This standard will ensure that consumers can make informed choices based on verified performance metrics when purchasing air purifiers.”

Key points about the BIS mandate include:

• All air purifiers sold in India must now comply with BIS standards
• Manufacturers need to display BIS certification marks on their products
• The standard establishes testing methods for performance evaluation
• Clean Air Delivery Rate (CADR) serves as the primary performance metric

Before this mandate, air purifier standards in India were largely unregulated, leading to inconsistent performance claims and difficulty in comparing different products. The new standards create a level playing field for manufacturers while giving consumers reliable quality indicators.

Technical Parameters in BIS Standard IS 17899:2022: What They Mean

The BIS standard IS 17899:2022 evaluates air purifiers based on several key technical parameters, with Clean Air Delivery Rate (CADR) being the most significant performance metric. Understanding these parameters helps consumers make informed purchasing decisions.

How CADR is Measured and What it Means for Performance

Clean Air Delivery Rate (CADR) is measured through a standardized testing procedure that quantifies how quickly an air purifier can remove specific pollutants from the air. This rate is typically expressed in cubic meters per hour (m³/h) or cubic feet per minute (CFM).

The testing process involves:

1. Placing the air purifier in a controlled chamber of specific dimensions
2. Introducing measured amounts of three pollutant types: smoke, dust, and pollen
3. Operating the purifier at maximum speed
4. Measuring the rate at which each pollutant type is removed

A higher CADR value indicates better performance. For example, an air purifier with a smoke CADR of 250 m³/h can clean a room more quickly than one with a 150 m³/h rating.

To determine the appropriate CADR for your room size, a simple formula applies: multiply your room area (in square feet) by 0.167. So for a 300 sq. ft. room, look for a CADR of at least 50 CFM.

While CADR is valuable, it has limitations. It measures performance at maximum speed only, which is often too noisy for regular use. It also doesn’t account for the removal of gases or VOCs, which require different filtration methods than particulates.

Beyond CADR, the BIS standard evaluates:

• Noise levels at different operating speeds
• Power consumption and energy efficiency
• Filter efficiency and durability
• Particle removal efficiency by size

These comprehensive parameters ensure that certified air purifiers meet a minimum standard of performance across various metrics, not just air cleaning speed.

BIS vs. QCI: Understanding Different Certification Systems

While BIS certification became mandatory in December 2023, the Quality Council of India (QCI) also launched its own AHAM Verifide program for air purifiers, creating two parallel certification systems in India. Understanding the differences helps consumers make better purchasing decisions.

The BIS certification serves as a mandatory baseline standard that all products must meet, ensuring minimum quality and performance requirements. In contrast, the QCI AHAM Verifide program offers manufacturers an optional additional certification that specifically validates CADR claims through a different testing methodology.

The two certification marks look distinctly different:

• BIS mark: Features the ISI mark with a standard number
• QCI AHAM Verifide: Features the AHAM Verifide logo with specific CADR ratings for dust, pollen, and smoke

Products can carry both certifications if they meet the respective requirements. For consumers, the BIS mark indicates compliance with mandatory Indian standards, while the AHAM Verifide mark provides more detailed performance information about specific pollutant removal rates.

How to Verify BIS and Other Certifications on Air Purifiers

For consumers, verifying whether an air purifier has authentic BIS or other certifications is crucial for ensuring product quality and performance. Here’s how to check for genuine certification marks.

Verifying BIS Certification

When purchasing an air purifier in India, follow these steps to verify authentic BIS certification:

1. Look for the ISI mark on the product, packaging, or manual
2. Check for the 7-digit BIS license number near the ISI mark
3. Ensure the standard number (IS 17899:2022) appears with the mark
4. Visit the BIS website (www.bis.gov.in) and use the “Verify License” tool
5. Enter the license number to confirm the certification’s validity

Authentic BIS marks should be clearly printed and not easily removable. The license number format follows a specific pattern, and the printing quality should be professional.

Verifying QCI AHAM Verifide Certification

For AHAM Verifide certification:

1. Look for the AHAM Verifide seal on packaging or the product
2. Check that the seal includes specific CADR ratings for dust, pollen, and smoke
3. Verify the certification online at ahamverifide.org

Common signs of counterfeit certification include:

• Blurry or poorly printed certification marks
• Missing license numbers
• Inconsistent information between product and packaging
• Certification claims without supporting marks

If you suspect fraudulent certification, report it to BIS through their official website or contact the consumer affairs department. This helps protect other consumers and maintains the integrity of the certification systems.

For online purchases, carefully examine product images for certification marks, and look for certification information in product descriptions. Reputable sellers will prominently display this information.
