How often should I clean the pre-filter on my air purifier?

It is generally recommended to clean the pre-filter whenever the filter replacement indicator lights up or approximately once a month, depending on usage and dust levels.

Can I wash the HEPA and carbon filters?

No, typically only the pre-filter is washable. HEPA air purification filters and carbon filters should be replaced, not washed or vacuumed.

What does the air quality light colored 'Ocean Blue' mean?

Ocean Blue generally indicates that the surrounding air quality is 'Fair'. Ensure your purifier is left running to further improve air quality to a 'Good' (Sky Blue) level.

Why is my air purifier showing an A-1 or A-2 code?

These codes typically indicate that maintenance is required. A-1 usually means it is time to clean the pre-filter, while A-2 indicates that the air purification and carbon filters need replacing. Refer to your manual for specific code instructions.
