This Panasonic Reverse Cycle Split System CS/CU-Z80YKR is more than just an air conditioner with a filter. Keep home cool in summer and warm in winter with this aircon suiting rooms larger than 55m2, including built in WiFi and 24hr 2-way active Air Purification approved by the National Asthma Council of Australia. Panasonic's NANOE-X Air Purification technology is more than just an air filter as an active air purifier that removes 99% of viruses, bacteria, allergens & mould, hydrating and deodorising rooms even in standby mode so home air is being constantly being cleaned, both in the room and cleaned inside the aircon by onboard filtration technology. AEROWINGS ensure maximum comfort from fast cooling/heating to quickly relieve hot or cold rooms then automatically adjusting to Shower Cooling redirecting airflow direction to maintain comfort with no breeze felt. Built in Wi-Fi means no need for an additional WiFi device to be installed, just connect to a network and can control the aircon from anywhere via a smartphone app or through voice control with Google or Alexa. It's also an ultra compact size as the indoor head unit is only 1040mm wide, so takes up much less space in the room than other air cons.
