E9 - philips Air Purifier

中文

含义

滤网寿命到期提示。净化器检测到HEPA或复合滤网已达到建议更换时间，需要更换新滤网。

常见原因

1. 滤网累计使用时间已达到建议更换周期（通常为12-24个月）
2. 实际使用环境空气质量差导致滤网提前饱和
3. 滤网计时器未在使用寿命结束后被复位
4. 滤网表面被过滤颗粒物完全覆盖——透气性严重下降
5. 滤网受潮发霉产生异味

自助排查

1. 打开滤网仓门检查滤网实际状态——颜色变黑严重需更换
2. 检查滤网是否有发霉、异味或明显破损
3. 如已更换新滤网——长按”复位”键3-5秒重置滤网计时
4. 在重度污染地区建议适当缩短更换周期至6-12个月
5. 仅更换真正饱和的滤网——非预过滤层可继续使用

English

Meaning

Filter life expired indication. The purifier has detected that the HEPA or combination filter has reached its recommended replacement schedule.

Common Causes

1. Filter accumulated usage time has reached the recommended replacement interval (typically 12-24 months)
2. Poor ambient air quality causing the filter to become saturated earlier than expected
3. Filter timer not reset after a previous filter replacement
4. Filter media surface completely covered with captured particulates — airflow severely restricted
5. Filter exposed to moisture, causing mold growth and odor

Self-Check Steps

1. Open the filter compartment and inspect the actual filter condition — severe darkening indicates replacement needed
2. Check the filter for mold, musty smell, or visible damage
3. If a new filter has already been installed, press and hold the “Reset” button for 3-5 seconds to reset the timer
4. In heavily polluted areas, consider shortening the replacement cycle to 6-12 months
5. Replace only the filter stage that is truly saturated — pre-filter layers may still be usable
