Airpura R400 Replacement Filter Kit
The genuine replacement filter kit for the Airpura R400. It restores your purifier's full three-stage filtration—cleanable pre-filter, activated-carbon bed, and True HEPA—so the R400 returns to capturing 99.97% of particles at 0.3 microns and adsorbing chemicals, gases, and odors like new.
What's in the kit
- Pre-filter — captures large particulate matter; vacuumable from the exterior of the purifier
- 8 lb activated-carbon filter — a premium blend that adsorbs VOCs, gases, and thousands of airborne chemicals
- True HEPA filter — traps 99.97% of fine particles as small as 0.3 microns (dust, pollen, dander, and other allergens)
Compatibility — does it fit my unit?
- Fits: Airpura R400 series
- Genuine Airpura filters—exact fit for the R400's pressure-sealed chamber
- Not for the larger R600/R700 units, which use the 18-lb kit
When to replace each filter
- Pre-filter: vacuum as needed; replace about every 12 months
- Carbon filter: about every 2 years
- HEPA filter: about every 3 years, depending on your air quality
Because Airpura filters are changed separately, you can replace only the stage that's spent and save on operating costs.
Why choose the genuine kit
- Exact fit and a proper pressure seal, so all the air passes through the media
- Full-size 8 lb carbon and genuine True HEPA—rated performance, not a reduced substitute
- All-metal filter construction with no plastic off-gassing
