Guardian Technologies support FAQ
Common questions about manuals, registration, and support for this brand.
-
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.
-
Can I wash the HEPA filter?
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.
-
How often should I replace the UV-C bulb?
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.
