xUpgrade your air quality with the XBWW APH4000 replacement filters
Designed for KNKA APH4000 air purifiers, this 2-pack replacement set supports large rooms up to 3,500 ft². The two-in-one filtration combines an H13 True HEPA layer with a loose-fill activated carbon section, delivering a cleaner, fresher feel to living spaces, bedrooms, and work areas.
What makes this filter effective
- 2-in-1 filtration: H13 True HEPA captures fine particles like dust, pollen, and pet dander while the activated carbon layer targets odors and smells from daily life.
- Odor control you can notice: The carbon design uses a looser fill to maximize activated carbon pellets, helping to reduce lingering smells from cooking, pets, and smoke.
- Efficient construction: The non-woven HEPA fabric and honeycomb carbon filter balance filtration performance with lower energy use and a lighter footprint.
