Asus launches air-purifying monitors starting at $129 — 27-inch and 34-inch models retail for $159 and $359

Asus VU Air Ionizer Series Monitor.

Earlier this morning, Asus launched a trio of VU Air Ionizer series monitors: the 23.8-inch IPS panel Asus VU249HFI-W, the 27-inch IPS Asus VU279HFI-W, and the 34-inch VA Asus VU34WCIP-W.

All VU Air Ionizer series monitors have a no-filter "VU Air Ionizer" that Asus claims can clear up to 90% of airborne dust and pollutants from an effective workspace coverage area of 1m³. Though we can certainly see how this can be useful for users in areas with poor air quality, the actual effectiveness of air ionizers as air purifiers is a hotly debated topic.
