On 22 April 2026, the European Commission adopted Regulation (EU) 2026/XXXX, requiring all industrial air filters placed on the EU market — including bag, panel, HEPA/ULPA modules, and integrated filtration units — to declare PM_0.3 filtration efficiency (tested per EN 1822-1:2023, amended version) and energy efficiency class (A–G scale), effective 1 July 2026. Exporters of air purifiers and dust collection equipment from China must revise product labels, technical documentation, and CE declarations of conformity; non-compliant units risk customs rejection or market withdrawal.

Event Overview

The European Commission officially published Regulation (EU) 2026/XXXX on 22 April 2026. The regulation mandates that, starting 1 July 2026, all industrial air filters sold in the EU must carry mandatory labeling for PM_0.3 filtration efficiency and energy efficiency class (A–G). Testing must follow the updated EN 1822-1:2023 standard. The scope covers bag filters, panel filters, HEPA and ULPA modules, and combined filtration units. The requirement applies to all products placed on the EU market after the effective date, and affects CE conformity documentation, technical files, and physical product labeling.

Which Subsectors Are Affected

Direct Exporters (Air Purifier & Dust Collection Equipment Manufacturers)

These enterprises are directly responsible for CE marking and compliance documentation. Because the regulation explicitly references CE conformity declarations and technical documentation, exporters must verify whether their current test reports cover PM_0.3 under EN 1822-1:2023 and whether energy performance data meets the new classification methodology. Non-compliance may result in refusal of customs clearance in EU member states.

Component Suppliers (Filter Media & Module Producers)

Suppliers providing HEPA/ULPA filter media, sealed modules, or pre-assembled filtration cassettes to OEMs or system integrators face indirect but material impact. Their technical specifications — especially efficiency curves and pressure drop data — now form part of downstream compliance evidence. If their test protocols do not align with EN 1822-1:2023’s PM_0.3 measurement requirements, OEMs may be unable to generate valid declarations.

System Integrators & OEMs (Industrial HVAC & Cleanroom Equipment Assemblers)

Companies integrating filters into larger air handling units or cleanroom systems must reassess full-system energy performance. The regulation applies to ‘combination units’, meaning total airflow resistance and power consumption across the entire filtration assembly — not just individual filters — will determine the final energy class. This requires coordinated testing and recalibration of fan-filter interactions.

Distribution & Compliance Support Providers (CE Consultants, Notified Bodies, Lab Services)

Third-party service providers involved in conformity assessment, technical file review, or certification testing must update their internal procedures to reflect the new PM_0.3 reporting and A–G classification framework. Labs accredited under EN 1822 will need to confirm alignment with the 2023 amendment; consultants must revise template declarations and label guidance accordingly.

What Relevant Enterprises or Practitioners Should Focus On — And How to Respond Now

Monitor official publication details and transitional provisions

The regulation number (EU) 2026/XXXX indicates the text is pending full Official Journal publication. Enterprises should track the final published version in the Official Journal of the European Union for any amendments to scope, exclusions, or grace periods — particularly regarding legacy stock or ongoing contracts signed before 1 July 2026.

Verify testing capability for PM_0.3 under EN 1822-1:2023

Current EN 1822-1:2023 includes revised test methods for most penetrating particle size (MPPS), now explicitly requiring PM_0.3 efficiency reporting for filters rated at H13 and above. Exporters should confirm whether their existing test lab reports meet this exact requirement — not just general ‘HEPA efficiency’ — and initiate retesting if needed.

Review energy data inputs for classification modeling

The A–G energy class is determined by specific airflow-to-power-consumption ratios defined in the regulation’s annexes. Unlike prior voluntary schemes, this classification depends on measured pressure drop at standardized airflow rates. Manufacturers must collect validated fan-filter system data — not just filter-only pressure drop — to assign the correct class accurately.

Update labeling, packaging, and technical documentation ahead of 1 July 2026

Labels must appear on the product itself or its immediate packaging, and technical documentation must include both PM_0.3 efficiency (%) and energy class (e.g., ‘Energy Class C’). Enterprises should audit current label templates, user manuals, and EU declaration drafts to ensure alignment before the deadline — especially for products already in EU-bound logistics pipelines.

Editor Perspective / Industry Observation

From industry perspective, this regulation signals a structural shift in EU environmental product policy: moving beyond particulate removal performance alone toward integrated performance metrics that link filtration efficacy with energy use. It is not merely an extension of existing eco-design rules, but the first binding requirement to mandate sub-0.3 µm efficiency reporting for industrial filters — a threshold previously reserved for laboratory-grade characterization. Analysis来看, the timing (entry into force just over two months after adoption) suggests limited transition time, implying regulators expect testing infrastructure and industry readiness to already exist. Observation来看, the focus on PM_0.3 reflects growing scientific consensus on ultrafine particle health impacts, while the A–G scale mirrors frameworks used for household appliances — indicating convergence of industrial and consumer regulatory logic. Current more appropriate interpretation is that this is both a compliance milestone and an early indicator of broader lifecycle-based product regulation in industrial air quality equipment.

This regulation marks a formalization of performance transparency for industrial air filtration in the EU — one that ties health-relevant filtration capability directly to climate-relevant energy use. Its significance lies less in novelty of concept and more in enforceability: it introduces legally binding labeling, verifiable test standards, and clear market access consequences. For affected enterprises, it is best understood not as a one-off compliance task, but as the first operational benchmark in an emerging regime where filtration efficiency and energy demand are assessed jointly.
