In today's increasingly industrialized and urbanized environment, indoor air quality has become a growing concern. As an effective air purification device, the wall-mounted 300CADR air fresh ventilation device has a filtration system that can effectively remove various types of pollutants, thereby providing a fresher and healthier indoor air environment.

1. Particle pollution: The filtration system of the wall-mounted 300CADR air fresh ventilation device usually includes multi-layer filters, the most common of which is a high-efficiency HEPA (high-efficiency particulate air) filter. This filter effectively captures fine particles in the air, such as dust, pollen, pet dander, bug remains, etc. The working principle of the HEPA filter is to intercept particulate matter in the air through a fiber mesh, thereby filtering out particulate pollutants in the air.

2. Household chemicals: In addition to particulate matter pollution, wall-mounted 300CADR air fresh ventilation units are usually equipped with activated carbon filters. Activated carbon has good adsorption properties and can absorb chemicals and odors in the air, such as formaldehyde, benzene, second-hand smoke, kitchen odors, etc. This filter can effectively purify the air, improve indoor air quality and make it fresher.

3. Bacteria and viruses: Some high-end models of wall-mounted 300CADR air fresh ventilation devices may also be equipped with UV-C ultraviolet lamps or photocatalytic filters. These technologies can effectively kill bacteria and viruses in the air. UV-C ultraviolet rays can damage the DNA structure of bacteria and viruses, thereby rendering them inactive. Photocatalytic filters use light reactions to convert harmful gases in the air into harmless substances, thereby purifying the air.

4. Cigarette smoke and volatile organic compounds: For families with smokers or frequent cooking activities, the wall-mounted 300CADR air fresh ventilation device can also effectively remove smoke and volatile organic compounds from the air. Through high-efficiency filters and adsorbent materials, this air purifier can adsorb and filter out smoke, oil smoke and volatile organic compounds in the air, thereby keeping indoor air fresh.

The wall-mounted 300CADR air fresh ventilation unit can effectively filter various types of pollutants, including particulate pollution, household chemicals, bacteria and viruses, cigarette smoke, and volatile organic compounds. By using this air purifier, you can enjoy fresher and healthier indoor air, protecting the health of you and your family.
