Genuine Airpura R400 replacement filters — keep your R400 Everyday Air Purifier running at full strength with the exact filters it was built to use. The R400 uses a three-stage filtration system, and refreshing each stage on schedule restores airflow, odor control, and particle capture.

The R400 filter system

  • Prefilter — captures large particles, dust, hair, and lint so the deeper filters last longer. Replace every 3–6 months.
  • Carbon filter — Airpura's coconut-shell activated carbon adsorbs odors, light chemicals, and gases. Typically lasts 2–4 years depending on use.
  • HEPA filter — captures fine airborne particles, allergens, and dust down to 0.3 microns. Typically lasts 3–5 years.

Choose what you need

Order a Complete Set to refresh every stage at once and save, or an individual filter if you only need to replace one stage. Want maximum particle capture? Choose the Complete Set with the Super HEPA (R414) upgrade.

All filters are genuine Airpura parts, guaranteed to fit the Airpura R400.
