Upgrade your Druiap KJ80 or Muliap KJ80 with LINNIW’s 3‑in‑1 KJ80 replacement filter. This compact unit houses an Ultra‑fine Pre‑Filter, a HEPA layer, and an Activated Carbon filter in a single, rotating 360° design. The setup aims to reduce fine particles and neutralize odors, helping rooms feel lighter and more breathable without making guarantees about outcomes.
With a streamlined structure and low energy footprint, the filter promotes efficient operation and steady performance throughout its service life. The combination of layers works together to maintain airflow and comfort in everyday living spaces, from living rooms to home offices.
Product dimensions are 4.9 × 4.9 × 5.9 inches, and the filters are designed specifically for Druiap KJ80 and Muliap KJ80 purifiers. Before ordering, please verify your model to ensure a proper fit. This is not compatible with Druiap KJ150 or Happi KJ80 units.
Included in this value pack is a two‑pack replacement set, offering convenience and cost efficiency for ongoing air cleaning needs. Regular replacement is recommended every 3–6 months, depending on usage and the level of air pollutants in your environment. A fresh filter helps sustain filtration performance over time.
LINNIW uses FSC‑certified paper in the filter design, reflecting a commitment to responsible sourcing. If you have any questions about fit or installation, our after‑sales team is ready to assist, and every order includes a 90‑day warranty or refund option for peace of mind.
