Product use:

1. Replacement Cycle:

Each filter layer has a different recommended replacement period depending on usage and environmental conditions:

• Pre-Filters: Replace every 10–60 days as needed.

• Intermediate Filter: Replace every 3–6 months.

• Activated Carbon Filter: Replace every 3–6 months.

• High-Efficiency Filter: Replace every 6–12 months.

By replacing the pre-filters regularly, the longevity of the main filters can be significantly extended, reducing overall costs.

2. Replacement Guidelines:

• Pre-Filters: Replace when over 70% of the surface is covered in oil or dust, and suction power decreases.

• Intermediate Filter: Replace when 70% of the filter area is clogged with dust and cleaning is ineffective.

• Activated Carbon Filter: Replace when dust buildup exceeds 70% and odor absorption weakens.

• High-Efficiency Filter: Replace under the same conditions as the activated carbon filter.

3. Maintenance Tips:

• Regular cleaning ensures optimal filter performance.

• Use genuine filters to maintain purification efficiency and prolong equipment lifespan.

• Periodic inspections and timely replacements can enhance machine performance and reliability.

4. Safety Precautions:

• Always use original filters to avoid compromising efficiency and machine longevity.

• Store and operate the product in a dry, cool environment away from high temperatures (above 60°C), flammable materials, and explosive substances.

• Regular maintenance minimizes risks of malfunction or safety incidents.
