Introduction
The Dhyala KJ03 Washable Pre-Filter Foam is specifically designed to complement your Dhyala KJ03 air purifier. These high-quality electrostatic cotton pre-filters act as the first line of defense, capturing larger airborne particles such as pet hair, dander, dust, and smoke. By effectively trapping these contaminants, the pre-filters help to extend the lifespan and maintain the efficiency of your air purifier's main filter. This package includes 6 pre-filters, providing a convenient and economical solution for consistent air purification.

Setup and Installation
Installing your Dhyala KJ03 pre-filter foam is a straightforward process. These filters are custom-fit for the Dhyala KJ03 air purifier, requiring no cutting and ensuring a perfect seal for maximum filtration efficiency.
- Power Off: Ensure your Dhyala KJ03 air purifier is turned off and unplugged from the power outlet before proceeding.
- Locate Filter Compartment: Identify the filter access panel on your Dhyala KJ03 air purifier. This is typically located on the back or side of the unit.
- Open Compartment: Open the filter compartment cover according to your air purifier's specific instructions.
- Remove Old Filter (if applicable): Carefully remove any existing pre-filter or main filter from the compartment. Dispose of old filters responsibly.
- Insert New Pre-Filter: Place one new Dhyala KJ03 pre-filter foam into the designated slot. Ensure it sits snugly and completely covers the air intake area. The custom design means it should fit without any gaps.
- Close Compartment: Securely close the filter compartment cover.
- Restore Power: Plug in your air purifier and turn it on.
Operating and Replacement Schedule
The pre-filter works continuously to protect your main filter and improve air quality. For optimal performance and to maintain the efficiency of your Dhyala KJ03 air purifier, regular inspection and replacement of the pre-filter are recommended.
- Regular Check: Visually inspect the pre-filter every 1-2 weeks for visible accumulation of dust, pet hair, or debris.
- Replacement Guideline: Based on typical usage, it is recommended to replace the pre-filter every 3 weeks. In environments with higher levels of contaminants (e.g., multiple pets, heavy dust, smoke), more frequent replacement may be necessary.
- 6-Pack Value: Each 6-pack provides approximately 4 months of use when following the 3-week replacement schedule.
Maintenance and Cleaning
One of the key benefits of the Dhyala KJ03 pre-filter foam is its washable and reusable design. Proper cleaning ensures prolonged effectiveness.
- Remove Filter: Turn off and unplug the air purifier. Carefully remove the pre-filter foam from its compartment.
- Rinse: Gently rinse the foam under lukewarm running water. You can gently squeeze the foam to help dislodge trapped particles.
- Deep Clean (Optional): If the filter is heavily soiled, a small amount of mild, non-abrasive soap can be used. Work the soap into the foam and then rinse thoroughly until all soap residue is gone and the water runs clear.
- Remove Excess Water: Gently squeeze out as much water as possible from the foam. Do not twist or wring forcefully, as this may damage the material.
- Air Dry Completely: Lay the filter flat on a clean, dry surface or hang it in a well-ventilated area to air dry. It is crucial that the filter is completely dry before re-installation to prevent mold or mildew growth and to ensure proper airflow. Do NOT use heat sources (like a hairdryer or direct sunlight) to speed up drying, as this can damage the filter material.
- Re-install: Once completely dry, re-install the pre-filter into your Dhyala KJ03 air purifier as described in the Setup section.
