Filter Replacement-Interval Reference¶
Industry-common replacement intervals for the five filter categories. Reference guidance only — always follow the vehicle/engine manufacturer's schedule first.

Intervals datasetdata/replacement-intervals.jsonv0.2.0 —reference-only.⚠️ reference-only — Intervals are industry-common REFERENCE values (kilometres / months), not Huiying product specifications and not a substitute for the OEM service schedule. Adjust for local conditions and confirm per application.
Reference intervals by filter type¶
| Filter type | Kilometres (reference) | Months (reference) | Note | Status |
|---|---|---|---|---|
Engine Air Filter (air-filter) |
10,000–20,000 km | 12 months | Shorten to 5,000–10,000 km in heavy-dust / sand regions | reference |
Engine Oil Filter (oil-filter) |
5,000–10,000 km | 6 months | Replace with every oil change; synthetic oil may extend the oil-change interval | reference |
Cabin Air Filter (cabin-filter) |
10,000–20,000 km | 12 months | Replace before the humid / rainy season to avoid musty smell | reference |
Fuel Filter (fuel-filter) |
20,000–40,000 km | 24 months | Diesel and commercial applications shorten toward the lower bound | reference |
Wiper (wiper) |
— (on condition) | 6–12 months | Replace on streaking, chatter or reduced clarity | reference |
Factors affecting replacement interval¶
| Factor | Effect |
|---|---|
| Dust / road conditions | Shortens engine-air, cabin and oil intervals (desert, unpaved, construction) |
| Climate humidity | Cabin filter replaced more often; watch for mould and fogging |
| Driving style | Stop-and-go / short trips shorten oil and fuel intervals |
| Fuel quality | Poor or contaminated fuel shortens fuel-filter life |
| Oil quality | Lower-grade oil loads the oil filter faster |
| OEM service schedule | Always the primary authority — this table is a secondary reference |

- 中国华北 / 西北沙尘地区: 空气滤清器建议缩短至 5,000–10,000 km 或按需更换；沙尘较大时推荐同时检查空调滤。 (signed: 小筑 ✍️)
- 中国南方潮湿地区: 空调滤建议每年雨季前更换，避免霉味与出风減弱；优先选择活性炭层款。 (signed: 小筑 ✍️)
- 柴油商用车队: 燃油滤建议按 20,000 km 或压差指示更换，对油水系统的保护价值高于件价本身。 (signed: 小筑 ✍️)
