• High Dust holding capacity
• Leak proof sealing thus no air leakage
• Pleats are equally spaced to maintain uniform air distribution
• Low initial and Final pressure drop
• High mechanical strength
• Fully cleanable /washable

HEPA filters meant to capture small particles like 0.25 micrometer to 0.3 micrometer. By having pre filter will reduce the burden on the HEPA filter or carbon filter. Pre filters improve the lifetime or longevity of HEPA filter.

Air purifiers are beautiful devices that improve our home environment and gives benefit to our health in long term. No matter how efficient the air purifier is, they all are quite complex and combine many technologies. Air cleaners are not just a fan with On/Off switch, which makes the air clean and fresh. Sophisticated science stands behind all air purifiers and their technologies. Since I don`t want to confuse you too much, I wouldn`t go deep into the science.
