Description
Indoor air in Kathmandu can change quickly during the day. Road dust enters through small gaps, smoke and odours build up indoors, and larger rooms can feel uneven because clean air does not always reach every corner.
HealthProtect™ 7740i is made for this kind of space. It combines advanced filtration, smart air monitoring, and 360° airflow to reduce dust, allergens, smoke particles, VOCs, odours, bacteria, and airborne pollutants across large rooms.
This makes it useful for living rooms, offices, master bedrooms, and homes where people spend long hours indoors and need cleaner air without constant manual control.

24/7 Protection with GermShield™
HealthProtect™ 7740i is designed to support air protection even when the purifier is on standby. GermShield™ technology monitors conditions and uses low air draft with plasma charging to help prevent bacteria and viruses from growing on the filters.
This helps keep the filter environment cleaner over time and supports continuous protection without requiring you to manually check the purifier.

These include:
- Hidden wheels for easier movement

These small design details make it easier to place, move, clean, and use the purifier as part of everyday life.
