Direct answer: A Wi-Fi or network-connected humidifier, fan or diffuser offered to UK consumers may fall within the UK consumer connectable product security regime. Manufacturers, importers and distributors should determine scope and ensure the required security controls and Statement of Compliance are in place before supply.

What changed in the United Kingdom
The UK Product Security and Telecommunications Infrastructure framework came into force for relevant consumer connectable products on 29 April 2024. Official guidance identifies duties covering manufacturers, importers and distributors and explains the need for a Statement of Compliance.
Three controls that affect product development
- Passwords: products should not rely on universal or easily guessable default passwords.
- Vulnerability reporting: the manufacturer needs a public route for security researchers and users to report vulnerabilities.
- Security-update transparency: users must be told the minimum period for which security updates will be provided.
How this changes an OEM brief
A smart-product brief should identify the wireless chipset, application, cloud platform, account system, default onboarding process, update method and support period. The packaging and user documentation must be aligned with the final hardware and software build. A non-connected version and a connected version should not share compliance wording unless both have been separately reviewed.
MistAirHome sourcing note
For UK projects, buyers should state whether app control, Wi-Fi, Bluetooth, voice-assistant integration or cloud functions are required. MistAirHome will treat cybersecurity documentation and the Statement of Compliance as model-specific deliverables rather than generic marketing claims.

Questions from buyers
Customer FAQ
Does every humidifier or fan need to meet the UK PSTI rules?
PSTI focuses on relevant consumer connectable products. A non-connected model may fall outside this regime, while a Wi-Fi, Bluetooth or app-connected model may be in scope. Confirm the final functions and legal classification before ordering.
What PSTI documents should a UK importer ask for?
For an in-scope model, ask for the Statement of Compliance, password design information, vulnerability-reporting contact, declared security-update period and supporting technical records for the exact product version.
Can the security-update period be customized for an OEM model?
It must be agreed during product definition because software ownership, app platform and support responsibility affect the declared period. MistAirHome can document the agreed arrangement in the final specification and quotation.
