Guardian Technologies support FAQ

이 브랜드의 매뉴얼, 등록, 지원에 대한 일반적인 질문입니다.

  • How do I reset the filter change light on my air purifier?

    After replacing the filter, press and hold the reset button (often the UV or Timer button, depending on the model) for 3 to 5 seconds until the light turns off or resets.

  • HEPA 필터를 세척할 수 있습니까?

    No, the combination HEPA filters are not washable. You may gently vacuum the outer charcoal layer to remove dust, but the filter itself must be replaced when dirty.

  • UV-C 전구는 얼마나 자주 교체해야 합니까?

    The UV-C bulb typically needs to be replaced every 10 to 12 months, depending on usage. A flashing blue light usually indicates it is time for a replacement.

  • Where can I order genuine replacement parts?

    Genuine replacement filters and bulbs can be purchased directly from the Guardian Technologies website to ensure proper fit and performance.

  • What do I do if my humidifier has a flashing water indicator?

    A blinking water indicator usually means the tank is low on water. Turn off the unit, refill the tank, and restart. If the issue persists, ensure the tank is seated correctly.
