EU Declaration of Conformity for Air Purifiers and Humidifiers: requirements and checklist
By Ing. Jaroslav Křepelka, Owner, DoC solutions s.r.o. · Updated 29 October 2026
In short: An air purifier or humidifier is declared under the Low Voltage Directive 2014/35/EU, the EMC Directive 2014/30/EU and the RoHS Directive 2011/65/EU, or the Radio Equipment Directive 2014/53/EU instead of LVD and EMC for app-controlled models. The safety standards are EN 60335-1 with EN 60335-2-65 for air cleaners and EN 60335-2-98 for humidifiers; ionisers must stay within the ozone limit of the standard, and UV-C lamps need a photobiological safety assessment.
Air purifiers and humidifiers are mains household appliances, so the Declaration of Conformity rests on the same directives as other appliances. What sets them apart are the extra features many models add: ionisers that can produce ozone, UV-C lamps, and Wi-Fi control with an app.
This page covers portable air purifiers (HEPA, ionising, UV-C), ultrasonic and evaporative humidifiers and aroma diffusers for household use. Dehumidifiers use a refrigerant circuit and EN 60335-2-40, which is outside this page.
Checklist: what your air purifier / humidifier declaration must contain
- Model exactly as on the rating label, listing each colour, plug and connectivity variant covered
- Name and postal address of the manufacturer (and of the authorised representative, if appointed)
- The statement that the declaration is issued under the sole responsibility of the manufacturer
- Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU, or the Radio Equipment Directive 2014/53/EU instead for Wi-Fi and Bluetooth models
- RoHS Directive 2011/65/EU
- The harmonised standards applied, with year and amendments
- Place and date of issue, name and function of the signatory, and the signature
Which EU legislation applies
| Legislation | Applies? | In the DoC? | Notes |
|---|---|---|---|
| Low Voltage Directive2014/35/EU | Applies | In the DoC: Yes | Mains appliances (220–240 V AC). Not cited separately for smart models, where RED covers safety. USB-powered mini humidifiers and diffusers are below the LVD range; their safety falls under GPSR. |
| EMC Directive2014/30/EU | Applies | In the DoC: Yes | Fan motors, ultrasonic transducers and electronic controls. Not cited separately for smart models. |
| Radio Equipment Directive2014/53/EU | Depends on model | In the DoC: Yes | Models with Wi-Fi or Bluetooth and an app. RED then covers safety, EMC and radio, and app-connected models must also meet Delegated Regulation (EU) 2022/30 on cybersecurity, applicable since 1 August 2025. |
| RoHS Directive2011/65/EU | Applies | In the DoC: Yes | Restriction of hazardous substances in electrical and electronic equipment. |
| Claims about killing viruses or bacteriaRegulation (EU) No 528/2012 (biocides) | Depends on model | In the DoC: No | Filters treated with a biocide, or devices that generate a biocidal substance in situ (for example ozone or other active substances), can fall under the Biocidal Products Regulation. Check before you make "kills 99.9 % of viruses" claims. This is not part of the CE declaration. |
| WEEE Directive2012/19/EU | Applies | In the DoC: No | Producer registration in every EU country where you sell and the crossed-out wheeled bin symbol. |
Typical harmonised standards
A harmonised standard gives presumption of conformity only in the version cited in the Official Journal of the EU. Always check the current list for each directive before you issue or update a declaration (European Commission: harmonised standards); the versions below are the ones commonly used at the time of writing, and the right selection depends on your product.
Electrical safety (LVD)
- EN 60335-1:2012 + A11:2014 + A13:2017 + A1:2019 + A14:2019 + A2:2019 + A15:2021Household and similar electrical appliances — safety — general requirements
- EN 60335-2-65:2003 + A1:2008 + A11:2012Particular requirements for air-cleaning appliances, including the ozone limit for ionisers
- EN 60335-2-98:2003 + A1:2005 + A2:2008 + A11:2019Particular requirements for humidifiers
- EN 62233:2008Electromagnetic fields of household appliances with regard to human exposure
- EN 62471:2008Photobiological safety of lamps and lamp systems, for models with UV-C or other lamps

Already have a declaration for your air purifier / humidifier?
A certification expert checks it against everything on this page and tells you exactly what to fix. Written report in 48 hours, €99 per product (excl. VAT).
Among other things, we check for the mistakes we find most often:
- The wrong part 2 standard
- Ozone from the ioniser not measured
- UV-C lamp without photobiological assessment
Common mistakes in air purifier / humidifier declarations
The wrong part 2 standard
Air purifiers are assessed against EN 60335-2-65 and humidifiers against EN 60335-2-98. A combined device needs both. Declarations that list only EN 60335-1 are incomplete.
Ozone from the ioniser not measured
EN 60335-2-65 limits the ozone concentration an air cleaner may produce. Ionising models need the measurement in the test report.
UV-C lamp without photobiological assessment
A UV-C lamp must not expose users to harmful radiation. The technical file needs an EN 62471 assessment and the interlock or enclosure design that prevents exposure.
Smart models declared under LVD and EMC
A purifier with an app is radio equipment: RED applies instead, with its radio standards and the cybersecurity requirements since 1 August 2025.
Unsupported hygiene claims
Claims about killing viruses or bacteria can bring the product under the Biocidal Products Regulation and are checked by marketplaces. Keep them backed by evidence, or leave them out.
What you need besides the declaration
- Technical documentation
- Safety test reports including ozone and, where relevant, photobiological measurements, EMC or radio reports, the cybersecurity assessment for smart models, and RoHS documentation. Keep it for 10 years.
- Instructions
- Cleaning and filter replacement instructions, water quality advice for humidifiers, and safety warnings in the language of each EU country where the appliance is sold.
- Economic operator in the EU
- An importer, authorised representative or responsible person established in the EU (Article 4 of Regulation (EU) 2019/1020).

Frequently asked questions
Which standard applies to an air purifier?
+
EN 60335-2-65 for air-cleaning appliances, used together with EN 60335-1. Humidifiers use EN 60335-2-98.
Does an air purifier with an app need RED?
+
Yes. Wi-Fi or Bluetooth makes it radio equipment, so the declaration cites the Radio Equipment Directive instead of the LVD and EMC Directives, plus the cybersecurity delegated act for app-connected models.
Is ozone from an ioniser regulated?
+
Yes. EN 60335-2-65 sets a limit for the ozone an air cleaner may produce, and the test report should include the measurement.
What does MyCECheck check on an air purifier declaration?
+
The directives for mains and smart models, the EN 60335 parts and their amendments, the ozone and UV-C evidence, the product identification and the EU economic operator. Written report within 48 hours.
