The humidification fresh air air conditioner's dual filtration system purifies outdoor air through a layered, collaborative approach. The first filter primarily intercepts large airborne pollutants. When outdoor air enters the humidification fresh air air conditioner, it first encounters the primary filter, which typically uses a medium-density fiber material to effectively capture larger particles such as dust, pollen, and catkins. If these pollutants enter the room, they not only affect air quality but can also clog the humidification fresh air air conditioner's internal components. The primary filter physically blocks most large pollutants from entering the system, easing the burden on subsequent fine filtration and ensuring that the air entering the next filter stage is free of significant impurities.
The second, high-efficiency (HEPA) filter focuses on deep purification of finer pollutants, further enhancing air cleanliness. Air passing through the primary filter enters the HEPA filter, which uses a finer filter material that captures even micron-sized particles, such as PM2.5, smoke particles, and bacterial spores. These fine pollutants can easily enter the lungs through inhalation, posing a potential health threat. High-efficiency filters, through a dual-action system of adsorption and interception, lock these tiny particles firmly within the filter media, preventing them from penetrating the filtration system and entering the room. This deep filtration thoroughly purifies outdoor air before it enters the room, effectively reducing the ingress of fine pollutants.
The material properties of the dual filtration system provide high purification capabilities, and the synergistic effect of the different filter media enhances filtration effectiveness. Primary filters are often made of washable non-woven fabric or nylon, offering excellent air permeability and durability, allowing for repeated use and reducing maintenance costs. High-efficiency filters often utilize meltblown fabric or activated carbon composite materials. The ultrafine fibers of meltblown fabric form a dense pore structure, making it highly efficient at capturing tiny particles. The activated carbon absorbs odors and some harmful gases in the air. The complementary properties of these two materials ensure high air flow while achieving targeted purification of different types of pollutants, resulting in fresher air entering the room.
The airflow design of the filtration system ensures sufficient contact between air and filter media, enhancing purification efficiency. The humidification fresh air air conditioner utilizes a rational air duct design within its dual filtration system, guiding air through the filters at an appropriate speed and angle. This prevents excessively fast airflow that results in inadequate filtration, or excessively slow airflow that affects fresh air volume. Air is evenly distributed as it passes through the filters, ensuring that every portion of air comes into contact with the filter media and maximizing the filter's purification effectiveness. This optimized airflow path ensures a more thorough filtration process, effectively capturing even pollutants at the edges of the airflow.
The dual filtration system effectively intercepts allergens in outdoor air, providing a safer air environment for sensitive individuals. Allergens such as pollen, dust mites, and mold spores in outdoor air are common triggers of allergic reactions. The primary filter intercepts larger allergens like pollen, while the high-efficiency filter captures smaller allergens like dust mite fragments and mold spores. Through the synergistic effect of dual filtration, these allergens are largely removed, significantly reducing the allergen content in the incoming air. This reduces the risk of discomfort from inhaling allergens for those with allergies and makes indoor air more suitable for allergies.
The filtration system's ability to absorb harmful gases further enhances indoor air quality. In addition to particulate matter and allergens, outdoor air may also contain harmful gases from vehicle exhaust and industrial waste, such as formaldehyde, benzene, and sulfur dioxide. The activated carbon or functional filter media in the dual-filtration system chemically adsorbs these harmful gas molecules to the surface, preventing them from entering the room. This purification of harmful gases ensures that the incoming fresh air is not only clean and particle-free, but also reduces the content of harmful chemicals, improving air freshness in multiple ways.
The long-lasting design of the dual-filtration system ensures continuous purification and reduces maintenance. The washable primary filter maintains its filtration capacity over time, allowing users to remove accumulated large particles with regular cleaning. The high-efficiency filter has a long service life and provides stable purification throughout its specified lifespan. This durable design eliminates the need for frequent filter media replacement, ensuring consistent purification results and long-term freshness of indoor air.
