Why do standard air filters go through the Claim?

🔬 Why do standard air filters need to pass Claim and Certified? 🏠

To be sure, "the air we breathe is actually clean" is not just an hype.

Some machines are filtered, proven, verified, which means they can really be bragged (claim that they have that property).

Some machines can do it in theory, but they don't dare to check it. How do we know they can do it? (The right thing is that they won't claim it - which brands in the market will only claim what they are sure of, which is correct)

📌 1. What is the performance claim?

"Claim" means identifying the performance of an air filter to a specified standard, subject to independent laboratory testing or through standards certified by the organization, such as:

Dust removal (PM2.5, PM10)

Ability to filter bacteria and viruses.

Reduction of chemicals and volatiles VOCs

Odor reduction and toxic gases such as Formaldehyde

Standards used to indicate the ability of air filters, such as:

✅ HEPA (High Efficiency Particulate Air Filter) → Must be able to capture 99.97% of 0.3 micron particles according to IEST-RP-CC-007.

✅ ULPA (Ultra Low Penetration Air Filter) → Must be able to capture 0.12 microns of particles 99.9995%

✅ CADR (Clean Air Delivery Rate) → Measure Air Cleaning Capacity (Cubic Feet Per Minute - CFM)

Organizations and standards that certify air filters

🏛 International Certifying Bodies

✅ AHAM (Association of Home Appliances Manufacturers) - USA

Provides CADR (Clean Air Delivery Rate) certification for measuring the ability to remove dust, pollen and cigarette smoke.

✅ ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) - USA

HVAC Standard Organization Certified MERV Ratings for Air Purifier

✅ UL (Underwriters Laboratories) - USA

Provide safety standards such as UL 2998 for non-ozone emitting filters and UL 867 for ozone emitting devices.

✅ IEST (Institute of Environmental Sciences and Technology) - USA

Define IEST-RP-CC007 Standard for HEPA / ULPA Filters

✅ NSF International - USA

Certify that the air filter has no harmful substance residue.

✅ CARB (California Air Resources Board) - USA

Control ozone standards in air purification equipment

✅ EPA (Environmental Protection Agency) - USA

Establish indoor air quality guidelines, including ozone emissions.

✅ EN 1822 (European Norm) - EU

It is standard for HEPA and ULPA Filter testing.

✅ ISO 29463 (International Organization for Standardization)

Standards further developed from EN 1822 for HEPA / ULPA

✅ GB / T 18801-2015 - China

A standard used to measure air filter performance in China.

✅ JEM 1467 - Japan

Japanese standards used to measure ozone efficiency and emissions

✅ TUV Rheinland - Germany

Test the air filtration performance of various devices.

✅ KCL (Korea Conformity Laboratories) - South Korea

Korean Air Purifier Industry Standard

📌 choosing to buy an air filter. What should I see?

✔ have certification from trusted bodies → such as AHAM, UL, CARB, EN 1822.

✔ has a CADR value suitable for room size → high CADR value = fast air filter

✔ Supports HEPA or ULPA → must pass a test that indicates the filtering percentage.

✔ No ozone emissions → Verify that UL 2998 / CARB standards have been met.

✔ Supports VOCs and Chemicals → If you want to filter poison gas, choose Activated Carbon Filter.
