1. Product Overview

This product isDual filter box filtering half-face mask, covering the mouth, nose, and jaw area; filters inhaled air through detachable filter boxes on both sides, and is widely used for respiratory protection in environments with dust, paint mist, organic odors, etc.

The mask body is manufactured using an integrated molding process, featuring a smooth surface and a compact structure; the contact area between the mask body and the face is equipped withSoft Elastic Sealing Ring, fits the facial contour, and is resistant to indentations after long-term wear. The filter boxes on both sides are made ofThreading Insertion StructureNo tools are required for loading and unloading; it can be operated with one hand. When the filter box becomes dirty or fails, simply remove it and replace it with a new one to continue use. The mask body can be reused, resulting in low operating costs.

This series consists ofNP303 / NP304 / NP305 / NP306Multiple models, also available with additional accessoriesProtective Goggles Set, can be selected flexibly based on the assignment scenario.

2. Core Selling Points

1. Dual filter box design for smoother breathing

左右 dual filtration boxes ensure balanced air intake, reducing inhalation resistance. The exhalation valve operates in one direction for exhaust, making breathing easier and minimizing the feeling of heat and humidity when worn. Water and steam are unlikely to accumulate inside the mask.

2. The filter box is replaceable, while the main unit can be used for a long time.

The filter box and mask are designed as a separate unit, with the filter box simply screwed on for immediate use; when the filter material (filter cotton/activated carbon) becomes ineffective, only the filter box needs to be replaced, eliminating the need to discard the entire mask—cost-effective and practical.

3. Soft sealing ring, fits tightly without air leakage

The edge of the cover is wrapped with soft, elastic material. Upon pressing, it rebounds and fits tightly around the nose bridge, cheeks, and chin, reducing air leakage gaps for comfortable wear.

4. Adjustable headband, multi-point force fixation

High-stretch knitted headband, with a length that can be adjusted freely via clips, and multiple points for securing both horizontally and vertically, ensuring stable wear. It is easy to maintain position during lowering or raising of the head; the headband is resistant to stretching and unlikely to break.

5. One-piece cover body, sturdy and durable

The cover body has high strength, is impact-resistant, and resistant to deformation. It features a high surface gloss, and the paint mist or dust adhering to it can be cleaned directly with a damp cloth.

6. Multiple models and color options available

Different models correspond to different filter box color schemes and filter materials (such as blue filter cotton, yellow filter cotton, etc.), facilitating differentiation based on protection requirements and personnel division of labor.

7. Optional goggles set

The combined set includes protective goggles with separate lenses. These lenses have high light transmission and provide a wide field of view. They can protect against splashes, dust, and liquid splatter simultaneously, offering dual protection for both breathing and eyes.

5. Applicable Scenarios

• Spray painting, brushing, grinding, polishing operations, paint mist prevention and organic odors
• Renovation construction, cutting trenches, brick cutting, cleaning, dust and particulate prevention
• Operation in chemical processing, printing and dyeing, and pharmaceutical workshops; protection against chemical gases and odors
• Welding assistance and machining in the workshop, protection against metal dust and oil mist
• Cleaning and disinfection, waste disposal, sewer maintenance, odor prevention and splashing protection
• Agricultural spraying, garden maintenance, preventing inhalation of pesticide mist
• Work environments in laboratories, warehouses, etc., with odors or low-concentration dust

6. Wearing Instructions

1. Before wearing, check if the mask has cracks or deformation, if the seal ring is aged, and if the headband is broken; ensure both side filters are tightened properly.
2. Release the adjustment clip, and cover the mouth and nose with the mask, ensuring it fits tightly around the nose bridge and seal ring.
3. Pull the headband to the back of the head and behind the neck, adjusting it to a proper tightness with even pressure.
4. Airtightness inspection:Block the air intake ports of both filter boxes with the palm, inhale slowly, and ensure the mask slightly sinks inward for several seconds without any air entering; if you feel air leakage, adjust the position again or tighten the headband.
5. You may enter the work area only after confirming there is no air leakage.

7. Replacement and Maintenance

• Filter box replacement:If there is a significant increase in breathing resistance, an unusual odor is detected, or the filter material is damaged or dirty, immediately leave the work area and replace the filter box; the filter box cannot be washed and reused.
• Mask Cleaning:After each use, wipe the interior and exterior of the cover with a soft cloth dipped in neutral cleaner, then clean it with clean water. Place it in a cool and well-ventilated area to dry naturally; avoid exposure to direct sunlight or high temperatures.
• Seal ring maintenance:Regular checks should be conducted to detect hardening or cracking; talcum powder can be applied in appropriate amounts to prevent adhesion.
• Storage:After cleaning and drying, place it back in the packaging box and store it in a cool, dry place free from corrosive gases, avoiding heavy pressure that could cause deformation.
• Specialized for specific purposes:It is recommended to use a one-person one-filter cover to prevent cross-use; in different operating environments, it is advised to use them separately or replace the filter box after thorough cleaning.

8. Precautions (Important)

9. Common Questions

Q: Can the filter box be washed and used again?
A: No. The filter cotton and activated carbon filters will become ineffective after washing, and only a new filter box can be used instead.

Q: Can I wear glasses?
A: Yes. The mask covers the mouth and nose without affecting the use of glasses; the goggles in the combo set have a large lens cavity design, allowing most myopic glasses to fit.

Q: How long can a filter cartridge last?
A: It depends on the pollutant concentration and usage duration in the working environment; there is no fixed time. Replacements are indicated by a significant increase in breathing resistance or the detection of an unusual odor. In high-concentration environments, it is recommended to shorten the replacement cycle.

Q: What should I do if the mask has an unpleasant smell?
A: The new product may have a slight material odor. After removal, place it in a well-ventilated area for some time. If any residue remains after use, please clean the cover according to the maintenance instructions and replace the filter box.
