Shield Aer

The Shield Aer takes Triad Aer's proven ion purification technology and makes it personal. Whether you're in a crowded office, on a plane, in a hospital waiting room, or simply going about your day in environments where air quality is out of your control — the Shield Aer creates a continuous protective ion field around your personal breathing zone. Worn around the neck or placed on a desk, the Shield Aer continuously emits negative ions that neutralize airborne bacteria, viruses, allergens, and pollutants in the air immediately around you. It's the same proactive ion technology that powers the V3 — just miniaturized for personal, portable use. The Shield Aer is rechargeable via USB, completely silent, and requires zero maintenance — no filters, no cartridges, no replacements of any kind. It's particularly popular with frequent travelers, healthcare workers, office workers in shared spaces, and anyone who wants personal air quality protection that goes wherever they go.
