CN Quality Check
Standards Comparison Tool
EXECUTIVE SUMMARY
The query pairs an air cleaner appliance standard (GB/T 18801-2022) with a filter media grade ("F8", EN 779:2012 / ISO 16890). These are different tiers and product categories — no direct equivalence exists. Correct pairing: appliance vs IEC 63086-1:2020/AHAM AC-1-2020; filter media vs GB/T 14295-2019 / GB/T 13554-2020. Procurement implication: you cannot certify an "F8" filter against GB/T 18801, nor an air cleaner against EN 779 — specify both standards separately.

⚠️ FLAG: GB/T 18801 vs "F8" is a tier + category mismatch — not a valid comparison.

|---|---|---|---|---|---|
| Particle CADR | Defined method (GB/T 18801-2022 §5) | Defined method (AHAM AC-1-2020) | Different test chamber/method | 附加测试后互认 (Mutual recognition after additional testing) | HIGH |
| Formaldehyde CADR | Required (GB/T 18801-2022 §5) | Not in AHAM AC-1 | N/A (only CN requires) | 不可互认 (Not mutually recognised) | MEDIUM |
| CCM (cumulative) | P1–P4 / F1–F4 tiers (GB/T 18801-2022 §6) | Not equivalent | N/A (only CN requires) | 不可互认 (Not mutually recognised) | HIGH |
Filter media grade "F8"
Chinese standard: GB/T 14295-2019 空气过滤器 (Air filters)
International equivalent: EN 779:2012 F8 (superseded) → ISO 16890:2016 — ⚠️ EN 779 withdrawn
Equivalence: NEQ (different classification metric)
Standard tier match: Both TIER 4 — valid comparison
| Parameter | Chinese Value (Clause) | International Value (Clause) | Deviation | Mutual Recognition | Procurement Impact |
|---|---|---|---|---|---|
| Efficiency metric | 中效/高中效 class (GB/T 14295-2019 §5) | F8 avg efficiency 90–95% @0.4µm (EN 779:2012 Table 1) [Verify: EN 779:2012 §5.3] | Different particle size & metric | 不可互认 (Not mutually recognised) | HIGH |
| Minimum efficiency | Verify: GB/T 14295-2019 §5 | F8 ≥55% @0.4µm (EN 779:2012) [Verify] | No direct mapping | 不可互认 (Not mutually recognised) | HIGH |
HEPA filter
Chinese standard: GB/T 13554-2020 高效空气过滤器 (HEPA filters)
International equivalent: EN 1822-1:2019 — ⚠️ verify class mapping
Equivalence: NEQ
Standard tier match: Both TIER 4 — valid comparison
| Parameter | Chinese Value (Clause) | International Value (Clause) | Deviation | Mutual Recognition | Procurement Impact |
|---|---|---|---|---|---|
| Efficiency class | H13/H14 etc. (GB/T 13554-2020 §5) [Verify] | H13/H14 (EN 1822-1:2019) | Class labels similar; test method differs | 附加测试后互认 (Mutual recognition after additional testing) | MEDIUM |
KEY DIFFERENCES SUMMARY
- Category mismatch — GB/T 18801 (appliance) vs F8 (media grade): no equivalence. 不可互认 (Not mutually recognised). HIGH.
- CADR test method — CN vs AHAM chamber differ; re-test needed. 附加测试后互认 (Mutual recognition after additional testing). HIGH.
- CCM & formaldehyde CADR — CN-only requirements. 不可互认 (Not mutually recognised). HIGH.
- Filter class metric — GB/T 14295 vs EN 779 F8 use different particle sizes. 不可互认 (Not mutually recognised). HIGH.

AUDIT FLAG RESOLUTION
- ✅ RESOLVED: GB/T 18801-2022 and GB/T 14295-2019 both CURRENT per official authority — no supersession notes added.
- ✅ FALSE POSITIVE (domain flag): "F8" is not a standard — it is a grade within EN 779:2012; usage valid only as a classification reference.
- 🔴 CRITICAL CORRECTION: Direct GB/T 18801 vs F8 comparison is invalid — split into appliance and media comparisons (done above).
- ⚠️ UNRESOLVED: EN 779:2012 F8 numeric efficiency values — verify against EN 779:2012 Table 1.
PROCUREMENT VERDICT
- Specify air cleaner to GB/T 18801-2022 AND target market standard (IEC 63086-1/AHAM AC-1) separately.
- Specify filter media to GB/T 14295-2019 (or GB/T 13554-2020 for HEPA); do NOT use "F8" as a CN spec.
- Require independent re-test for CADR if dual-market claim needed.
- Confirm CCM/formaldehyde CADR if CN market.
- Verify EN 779 F8 numeric values before accepting EU filter claims.
- Confirm CCC/CQC applicability for the appliance.
