KNOKOO High-Efficiency Filter Cartridge

I. Product Overview

The KNOKOO High-Efficiency Filter Cartridge integrates advanced filtration technology with premium core materials, focusing on indoor air purification and overall quality-of-life improvement. It establishes a three-in-one functional system covering precision particulate filtration, gaseous pollutant purification, and odor source elimination.

The filter not only delivers highly efficient interception of ultrafine particulate contaminants, but also powerfully removes a wide range of harmful gases and odors, ensuring clean and harmless output air. It is widely applicable to medical, industrial, and residential air purification scenarios.

II. Core Functional Positioning

As the ultimate purification barrier within an air filtration system, the KNOKOO high-efficiency filter is specifically designed to capture ultrafine particles of 0.3 μm and above. It precisely intercepts viruses, bacteria, smoke, dust, and radioactive particulates, achieving a filtration efficiency of 99.97%–99.99%, fully compliant with international HEPA H13/H14 standards.

The filter provides dust-free and sterile air protection for environments with extremely high cleanliness requirements, such as medical facilities, precision manufacturing, and scientific research, forming a robust safeguard for both production safety and personnel health.

III. Core Materials & Technologies

1. HEPA Main Filtration Layer – Ultrafine Particle Capture Core

• Electret Glass Fiber Media
  Manufactured from 0.3 μm borosilicate glass fibers and treated with electron-beam electret technology, the media forms a permanent electrostatic field. Through electrostatic attraction, it efficiently captures ultrafine particles in the 0.1–0.3 μm range, including viruses and bacteria, achieving a single-layer capture efficiency of up to 99.6%.

• Nano PTFE Membrane Lamination
  An expanded polytetrafluoroethylene (ePTFE) microporous membrane (pore size 0.1–0.5 μm) is laminated onto the glass fiber surface. Its smooth membrane structure enables a “non-stick dust” surface filtration mechanism, reducing airflow resistance by approximately 30% compared to conventional filter media, while maintaining high filtration efficiency and low pressure drop.

2. High-Iodine Coconut Shell Activated Carbon – Gaseous Pollutant Purification Core

To address gaseous pollutants and odor removal, the filter incorporates a high-iodine-value coconut shell activated carbon layer. The raw material is sourced from premium tropical coconut shells from Indonesia and processed through 1200°C high-temperature physical activation.

With an iodine value of ≥1200 mg/g, its adsorption capacity is more than twice that of standard activated carbon, enabling powerful removal of various harmful gases and persistent odors.

IV. Core Filtration Performance

The filter precisely intercepts PM0.3 and larger particles, with a PM0.3 filtration efficiency ≥99.6%, and a virus and bacteria interception rate exceeding 99.9%. Simultaneously, it efficiently purifies gaseous pollutants and odors, delivering:

• Formaldehyde adsorption capacity ≥350 mg/g

• Benzene-series compound adsorption capacity ≥280 mg/g

It effectively eliminates chemical odors, garbage decay smells, malodorous gases, smoke, and other unpleasant odors, achieving comprehensive purification of particulates, gases, and odors.

V. Key Product Advantages

1. Medical-Grade High-Efficiency Filtration
   Equipped with HEPA-grade core media, the filter delivers precise ultrafine particle capture and meets stringent medical-grade filtration standards, ensuring ultimate protection for clean environments.

2. Four-Mechanism Synergistic Purification
   By integrating sieving, inertial impaction, interception, and diffusion adsorption, the filter achieves deep nano-scale particle capture. Targeted purification of toxic and harmful gases delivers breakthrough adsorption performance.

3. Energy-Efficient, Low-Resistance Design
   Optimized filter structure and airflow channels result in an initial pressure drop of ≤45 Pa, reducing fan energy consumption by approximately 30%, making long-term operation more energy-efficient.

4. Extended Service Life
   A thick, high-capacity activated carbon filling design, combined with upstream medium-efficiency pre-filtration, significantly reduces the load on the core filter layer, effectively extending overall service life.

VI. Maintenance & Replacement Guidelines

1. Replacement Criteria

Replacement is required under the following conditions:
① Noticeable reduction in suction or the appearance of odors at the exhaust outlet;
② Airflow does not recover after replacing the pre-filter or medium-efficiency filter.

Regular replacement ensures continuous high-performance operation and stable output of clean air.

2. Recommended Replacement Interval

• Standard clean environments: 12–18 months

• High-pollution or harsh environments: 6–8 months

3. Daily Maintenance Recommendations

• Pre-filter mesh: Rinse with clean water once per month (do not scrub). Allow to air dry before reuse.

• Activated carbon layer: Expose to sunlight for 2 hours once per quarter to restore approximately 30% adsorption capacity (avoid high-temperature baking to prevent carbon degradation).
