Particles larger than about 2 µm are primarily filtered out by the upper respiratory passages. They can cause allergic reactions and impair comfort. Particularly people with allergies suffer from these small particles. HEPA filtration remove over 99 percent of airborne particles, which protects disaster survivors and recovery personnel. This prevents common health issues such as allergic reactions and illnesses while improving the quality of the air inside recovery spaces. If your HEPA filter becomes clogged due to excessive use or poor maintenance, its ability to clean the surrounding environment can be impaired. This causes dust, dirt, and other particles to be stirred up rather than removed. That’s why we need to change replacement hepa filtration.
Srilan’s replacement hepa filtration media is well known with its high CADR, low resistance, stable shelf life. Melt blown materials are mainly used in air purifier as core filtration layer, these materials are laminated with activated carbon material or different supporting material. Composite filtration materials are mainly used in air purifier as core filtration layer, these materials can be applied directly to produce many different kinds of air filters. Supporting materials are mainly used in air purifier as core backing layer, and Srilan company can produce flame retardant, antibacterial and colorful supporting materials to meet different needs.
