Upgrade your A1 air purifier with HIHEPA's 2-pack replacement filters. These filters are designed for seamless compatibility with VEWIOR A1, HQSC-50, HQKJ-80, Ameifu AP01W, KOIOS HQKJ-50, and Tailulu PUR0003 purifiers, supporting everyday air-cleaning routines in homes, offices, and small workspaces.
Built to fit a range of popular models, the A1 replacement filters slip in without tools, helping you maintain clean air with minimal downtime.
Each cartridge combines three filtration stages in one: True HEPA, an activated carbon layer, and a pre-filter. The combination targets fine particles, odors, and hair or lint before they reach the core filter.
Replacement timing depends on usage and environment. In typical home settings, aiming for a 3–6 month replacement interval helps keep your purifier performing consistently. The pack is designed to simplify maintenance and keep your device ready for use without fuss.
HIHEPA stands behind its products with responsive customer service. If you have questions about compatibility or installation, our team is ready to assist you and ensure you get the support you need.

A: Yes—it's designed for VEWIOR A1, HQSC-50, HQKJ-80, Ameifu AP01W, KOIOS HQKJ-50, and Tailulu PUR0003.
Q: How often should I replace the filter for best results?
A: Replace every 3–6 months depending on use and environment; the pre-filter is washable and the pack includes a cleaning brush.
