Third-party filters may not meet the same quality standards, leading to poor sealing, reduced efficiency, or potential device issues. For best results, always use original KNKA filters to maintain consistent air purification performance.
𝐀𝐝𝐯𝐚𝐧𝐜𝐞𝐝 𝐅𝐢𝐥𝐭𝐫𝐚𝐭𝐢𝐨𝐧 𝐓𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐲: Traps fine particles down to 0.3 microns, such as dust, pollen, and pet dander, helping maintain a fresh and comfortable indoor environment. The activated carbon layer helps reduce common household odors from cooking, pets, and smoke.

𝐄𝐚𝐬𝐲, 𝐓𝐨𝐨𝐥-𝐅𝐫𝐞𝐞 𝐈𝐧𝐬𝐭𝐚𝐥𝐥𝐚𝐭𝐢𝐨𝐧: No tools are required—simply replace the filters in a few easy steps. The replacement interval may vary depending on usage and environment. Tip: Before replacing, turn off the power and remove the used filters. After installing new ones, turn on the purifier and press and hold the Filter button for 5 seconds until you hear three beeps to reset the indicator light.
𝐏𝐫𝐚𝐜𝐭𝐢𝐜𝐚𝐥 𝐇𝐨𝐦𝐞 𝐀𝐜𝐜𝐞𝐬𝐬𝐨𝐫𝐲: These replacement filters are a functional addition to any home using the APH4000 air purifier—suitable for daily use and easy to keep on hand for regular maintenance.
