Description
xUpgrade your Blue Pure 411i Max or 411a Max purifier with Leemone's AllergenBlock replacement filter. Designed to slide in as a seamless replacement, it supports a smooth airflow path and helps sustain the purifier's performance without requiring changes to your routine.

Maintenance and support
For ongoing top performance, Leemone recommends replacing the filter approximately every six months under typical usage. Real-world timing depends on room size, air flow, and environmental factors.
If you encounter any quality issues or questions, our 24/7 Leemone support team is ready to help resolve concerns promptly.
What to expect in daily use
After installation, you may notice smoother airflow and a subtle reduction in lingering odors, especially in spaces with regular cooking or pet activity. Results vary by room size, ventilation, and usage patterns, but the replacement process is designed to be quick and easy.
Environmentally conscious design means the carbon layer relies on FSC-certified charcoal powder, and the packaging is kept minimal to support responsible disposal and recycling where available.
