Description
xRefresh the air you breathe with the Letsport Replacement Filter, designed to fit the Kokofit KJ510B air purifier. This 3-in-1 replacement combines a fine pre-filter, a true HEPA H13 layer, and an activated carbon stage to address a wide range of everyday air concerns. While results depend on room size, usage, and environment, the design offers several potential benefits that many users appreciate in real life.
Three-layer filtration for comprehensive coverage
The core filtration system blends a fine preliminary filter, a HEPA H13 filter, and activated carbon. The HEPA layer traps tiny particles while the carbon layer targets odors and some gases, helping keep the air feeling cleaner between cleanings.
- True HEPA technology with H13 grade for fine particle capture
- Activated carbon filter absorbs odors and smoke
- 3-in-1 design — pre-filter, HEPA, carbon in one replaceable unit
All-around airflow, built for real rooms
With a cylindrical inlet and 360° filtration, air passes through the filter from multiple angles. This design is intended to help reduce lingering dust, pollen, and persistent smells, contributing to a fresher room ambience.
- 360° filtration supports thorough air cleansing
- Effective against dust, pollen, and smoke in common living spaces
- Designed to fit Kokofit KJ510B units for seamless replacement

When it’s time to refresh, you can swap in the new filter quickly—no tools required. Just remove the old unit and insert the replacement after removing its plastic packaging. This makes routine maintenance smoother without downtime.
- Quick and easy to replace
- No tools needed to complete the swap
