Ultra Nano Filter


The Ultra Nano filter is coated with one-billionth meter super fine nano fiber.
The air hole of it is 20 times smaller and closer than common polyester filter.

By Surface filtration, the dusts are not stuck in the hole of fiber unlike depth filtration.
The dusts are easy to be off when air-pulsing, so the life cycle is longer than common filter.
