Description

Compatible Models: This APH4000 replacement filter only compatible with KNKA APH4000 Air Purifiers. Please verify your purifier model before purchasing. (Note: It is not compatible with the AP2000WF/ APH3000)

Multi-Stage Filtration: This APH4000 filter features an efficient 2-in-1 filtration system, combining a true HEPA filter with an activated carbon layer. It effectively filters airborne particles such as hair, pet dander, lint, and odors.

Powerful HEPA Filtration: The HEPA filter efficiently filters out 99.97% of particles as small as 0.3 microns—including pollen, dust, pet dander, and more.

Maximum Carbon Load: At the heart of our carbon filter is an advanced infusion technology that loads carbon to 80% of the honeycomb's capacity. This creates a deeper clean, maximizes carbon usage, and delivers reliable, all-around purification with no untreated air.

Package includes 4x APH4000 filter, 6x Aroma Pads, Replacement is simple and requires no tools. For optimal performance, we recommend replacing the filter every 6-8 months under normal conditions.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $14 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for CFKREYA products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
