Intertek is one of the world's most respected independent testing laboratories, operating in over 100 countries. For a DIY kit, independent certification answers a critical question: does it actually perform as advertised? Intertek, one of the world's leading quality assurance providers, has independently tested and verified the performance of components used in our DIY air purifier kits. Without third-party verification, manufacturers can make unsubstantiated CADR and filtration claims. Our Intertek certification covers CADR testing to the ANSI/AHAM AC-1 standard, particle filtration efficiency to ISO 16890, electrical safety to UL 507, noise assessment to ISO 3746, and energy consumption to IEC 60335.
Energy Star 2026 certified components ensure your DIY air purifier operates with maximum efficiency, saving money and reducing environmental impact. Energy Star 2026 sets strict limits on watts-per-CADR — meaning certified products must deliver more clean air per watt of electricity than earlier standards required. At our operating power of 50–100W, our kits cost approximately €35–70 per year to run continuously. A comparable commercial HEPA purifier consuming 150–200W costs €105–140/year. Over 5 years, the running cost difference alone saves €350–450, on top of the lower purchase price.
Most commercial air purifier brands (Dyson, Philips, Blueair) are Energy Star certified, but few publish full Intertek test reports. Our kits share the same certification body and testing protocols while achieving CADR figures of 300–600 m³/h — matching or exceeding commercial models priced at €300–800. The key difference: our kits use replaceable MERV 13–16 filters available from any hardware supplier, rather than proprietary filters that cost €50–120 each.
CE Marking is mandatory for electrical products sold in the European Economic Area. It confirms that the product meets EU health, safety, and environmental protection requirements — specifically the Low Voltage Directive (2014/35/EU) and the EMC Directive (2014/30/EU). Our fan components are CE-marked and FCC compliant. UL 507 (Standard for Electric Fans) is the North American safety standard our fans are also tested to, confirming safe electrical operation. For EU buyers, CE Marking is the legally required certification — our kits comply fully, allowing us to ship to all 27 EU member states plus EEA countries.
