Air purifiers, humidifiers and dehumidifiers

• Directive 2014/35/EU — Low Voltage
• Directive 2014/30/EU — EMC
• Regulation (EU) No 528/2012 — Biocidal Products where an antimicrobial claim is made
• Regulation (EU) 2017/1369 — energy labelling for some groups
• Directive 2012/19/EU — WEEE

Who has to appoint one

Manufacturers and sellers outside the Union placing air treatment appliances on the EU market. The category expanded rapidly after 2020 and attracted enforcement precisely because of the claims made rather than the electrical design.

Thresholds and exemptions

None for the electrical rules. The biocidal boundary has no threshold either: a single antimicrobial claim brings Regulation 528/2012 into play.

What must appear on the label

CE marking, manufacturer and EU representative details, model and batch number, rated voltage and power, the WEEE symbol, and where UV-C is used, warnings on eye and skin exposure and on ozone generation.

Marketplace fields

Marketplaces remove listings claiming that a purifier kills viruses or bacteria unless the product is authorised as a biocidal product, and this was one of the most enforced claim categories after the pandemic.

Documentation you must hold

EU declaration of conformity, technical file, electrical and photobiological test reports, filter efficiency data supporting any HEPA claim, ozone emission measurements where ionisers or UV-C are used, and WEEE and packaging registrations. Where an antimicrobial claim is made, the biocidal product authorisation and an active substance from an Article 95 listed supplier.

Standards and testing

EN 60335-2-65 and related parts for electrical safety, EN 55014 for EMC, EN 1822 or ISO 29463 for HEPA filter classification, and ozone emission testing. Efficacy claims about particle or pathogen reduction require chamber testing under a recognised protocol.

Language requirements

Instructions, warnings and claim substantiation in the language of each member state of sale.

When it applies

Before placing on the market. Biocidal authorisation, where required, takes years and cannot be obtained retroactively, so the claim must be dropped or the product withdrawn in the meantime.

How long records are kept

Ten years for the technical documentation; EPR declarations per national law.

What happens if you do not comply

Withdrawal and fines for unauthorised biocidal claims, which are treated as a serious infringement rather than a marketing error. Electrical defects bring Safety Gate alerts, and ozone-emitting devices have been recalled in several member states.

Who enforces it

Market surveillance authorities, national biocides authorities, WEEE registers and consumer protection authorities for the claims.

Where the boundary lies

The dividing line is the claim, not the technology. 'Filters particles' is a product performance claim under general consumer law. 'Kills 99.9% of viruses and bacteria' is a biocidal claim requiring an authorised product, which a responsible person or an Article 4 operator cannot substitute for. UV-C devices additionally raise photobiological safety issues that are checked in inspections.

Questions we are asked

Can we say our purifier removes 99.9% of viruses?

Only with a biocidal product authorisation for that claim. Without it the statement is unlawful, and it is the single most enforced issue in this category.

Do humidifiers need any of this?

Yes for the electrical, WEEE and packaging obligations, and any antibacterial cartridge claim brings the biocidal regime.
