High efficiency
The appliance offers high efficiency, reaching class A+++ for heating and cooling, contributing to considerable energy savings.
Supreme comfort
- Aerowings 2.0, with full-length vents for comfortable airflow
- Ultra-quiet operation (19 dB(A))
Equipped with nanoe™ X Mark 3 Generator, the new Etherea has an impressive amount of hydroxyl radicals, 100 times more than in the previous model, ensuring high performance in air purification.
Internal cleaning and drying of the unit is achieved using nanoe™ X technology
Thanks to the internal cleaning operation, the air conditioning unit benefits from effective sanitation. Nanoe™ X eliminates up to 99% of bacteria, viruses and mold on the filter, evaporator and air outlet.
With a special coating applied to the cross-flow fan, it prevents dust accumulation and helps combat certain bacteria and mold.
nanoe™ X: Enhanced 24/7 Protection
With nanoe™ X technology, the air is continuously purified, providing a cleaner and more pleasant environment throughout the day. It can be activated together with the heating or cooling functions, or operate autonomously when you are away, ensuring maximum protection in your home, controlled via the Panasonic Comfort Cloud app.
Fresh air before you get home
The nanoe™ mode can be activated to inhibit pollutants and deodorize the space, giving you a fresh and clean environment when you return home.
Advanced air conditioner control via smartphone
Nanoe™ X purifies the air, providing a clean and comfortable environment. It works alongside your heating and cooling systems when you are at home and can operate on its own when you are away. It protects your home, and with the Panasonic Comfort Cloud app, control is simple and quick.
Technology for ultimate comfort
- Aerowings 2.0 – for optimal air distribution
Panasonic has developed Aerowings technology, which uses two independent and flexible blades that concentrate the airflow to heat or cool the room in a short time, distributing the air evenly throughout the room.
Larger secondary blade (72 mm), twice as large as traditional models, greatly improves the ability to increase airflow.
- Diffuse heating
In heating mode, Aerowings 2.0 directs a concentrated flow of air downwards, imitating the effect of underfloor heating, and the warm air rises and is distributed evenly throughout the room.
- "Shower cooling"
The Aerowings 2.0's "shower cooling" function directs the air flow evenly towards the ceiling, spreading the coolness comfortably throughout the room. Instead of a concentrated cold current in one spot, the air gradually descends, creating a pleasant and cool environment.
