MODELS: AC151
FILTER REPLACEMENT
The “Filter Reset” indicator will light when it is time to replace your filter. Depending on usage
and environmental conditions the filter will last approximately 6 months. The inside pleats of the
filter will turn from white to grey when it is dirty and needs replacing. It is important to maintain
and change the filter to continue to optimize the performance of the air purifier.
IMPORTANT: Do NOT wash and re-use the filter. Please contact Customer Service to purchase
a replacement filter or visit guardiantechnologies.com.
