Understanding nanoe™ X Technology
The nanoe™ X technology, integrated into Panasonic air conditioning solutions, actively improves indoor air quality, contributing to the well-being and comfort of occupants. It can be used in residential settings for families, couples, or individuals, as well as in commercial applications such as gyms, restaurants, hotels, supermarkets, and offices.

Figure 2.3: How nanoe™ X Works. This diagram illustrates the mechanism of nanoe™ X, showing hydroxyl radicals inhibiting pollutants. Hydroxyl radicals are unstable molecules that react with other elements like hydrogen, capturing them. nanoe™ X distributes nano-sized particles throughout the environment via humidity, offering benefits without requiring maintenance or filter changes.
Benefits of nanoe™ X
nanoe™ X particles can inhibit the development of various pollutants such as certain viruses and bacteria, some allergens and pollens, molds, and odors, neutralizing their unpleasant effects. Even tightly woven fabrics can be treated with nanoe™ X technology, including curtains, blinds, carpets, and furniture, as well as the most difficult surfaces.
