1. High-Efficiency Dual Purification System The Avior air purifier combines Active Purification and Passive Purification for comprehensive air cleaning. Active Purification Releases 20 million negative ions to actively neutralize airborne particles and pollutants. Helps capture dust, allergens, and harmful substances before they settle. Simulates the fresh air found in forests, waterfalls, and coastal environments. A 30-minute negative ion release can increase indoor oxygen freshness, creating a healthier living environment. Supports better metabolism, enhances immunity, freshens indoor air, and helps reduce airborne contaminants. Passive Purification 3-Layer, 4-Stage High-Efficiency Composite Filter 1.
