CE certification for air purifiers, complying with EN 60335-2-65 and EN 1822-5 High-Efficiency Particulate Air (HEPA) filtration standards.

For air purifier manufacturers aiming to expand into the European market, CE certification is an indispensable "passport." It is not only a legally mandated requirement but also an authoritative endorsement of product safety, performance, and reliability. The EN 60335-2-65 and EN 1822-5 standards form the core technical pillars of the certification, imposing stringent requirements on products from the two dimensions of electrical safety and filtration performance, respectively.

The EN 60335-2-65 standard, officially titled "Safety of household and similar electrical appliances – Part 2-65: Particular requirements for air purifiers," is an extension and refinement of the general safety standard EN 60335-1. This standard focuses on the unique risks that may arise in the specific category of air purifiers. The testing focuses on: structural design to prevent users from touching dangerous moving parts (such as fans); assessing whether the machine will overheat or catch fire under prolonged operation or simulated failure conditions; checking whether the release of harmful byproducts such as ozone is within safe limits; and ensuring the mechanical stability of the product and the adequacy and accuracy of labeling instructions. This series of rigorous assessments aims to fundamentally protect the personal and property safety of end users.

If EN 60335-2-65 concerns "safety," then the EN 1822-5 standard directly addresses the core of air purifier "efficiency"—the High-Efficiency Particulate Air (HEPA) filter. This standard provides a scientific and unified international method for the performance testing and classification of HEPA filters. It uses the Most Penetrating Particle Size (MPPS) method for testing; particles of this size are the most difficult to filter, therefore the test results most accurately reflect the filter's performance under the most severe operating conditions. According to EN 1822-5, HEPA filters are precisely classified into multiple grades, including E10, E11, E12, H13, and H14. Only filters rated H13 and above can generally be referred to as "HEPA" grade. For example, an H13 grade filter must have a filtration efficiency of ≥99.95% for MPPS particles, while an H14 grade filter must have ≥99.995%. Manufacturers must test according to this standard and accurately label the grade of the filters used in their products; any exaggerated claims may result in legal risks and reputational damage.

Integrating these two standards into the CE certification process requires manufacturers to follow a clear path. First, they must choose a qualified EU Notified Body for cooperation. Next, they need to provide detailed technical documentation, including product design drawings, circuit diagrams, a list of key components, a risk assessment report, and a draft declaration of conformity. Experts from the Notified Body will conduct comprehensive safety testing according to EN 60335-2-65 and review the evidence of conformity to EN 1822-5 (usually a filter test report issued by an accredited laboratory). Only after all items meet the standard requirements can the manufacturer obtain a CE certificate and be entitled to affix the CE marking to the product.

A deep understanding and compliance with the requirements of EN 60335-2-65 and EN 1822-5 is of strategic significance for manufacturers. This is not only the bottom line for avoiding legal risks and ensuring smooth customs clearance, but also the key to building core product competitiveness and winning the trust of European consumers. An air purifier with a clear and authentic H13/H14 grade HEPA label and comprehensive safety certifications can stand out in a highly competitive market and establish a professional, reliable, and high-quality image. Therefore, treating these two standards as guiding principles for product development and quality control, rather than a passive compliance burden, is a wise move for companies to achieve sustainable overseas expansion.
