About This Item

• Extraordinary 27.8 SEER2 Efficiency: At 27.8 SEER2, the Panasonic ETHEREA is among the most energy-efficient residential mini splits ever manufactured. Annual electricity costs can be 40-50% lower than 14 SEER conventional units — paying for itself in energy savings within a few years.
• Nanoe-X Air Purification Technology: Panasonic’s patented Nanoe-X technology generates hydroxy radicals that actively inhibit 99.99% of viruses, bacteria, mold spores, and allergens in the air and on surfaces. Functions simultaneously with normal heating and cooling.
• EcoNavi Smart Sensing: Built-in human presence sensors detect when rooms are occupied, automatically adjusting output for maximum efficiency when empty and optimal comfort when occupied. The EcoNavi system can reduce energy consumption by up to 30% versus non-sensing competitors.
• Ultra-Quiet Operation – 19dB Indoor: The ETHEREA’s indoor unit operates at an almost inaudible 19dB at the lowest fan speed — quieter than a whisper at 1 meter. The Japanese-engineered fan design virtually eliminates noise without sacrificing airflow efficiency.
• Built-in WiFi + Panasonic Comfort Cloud App: Control temperature, fan speed, operating mode, and view energy reports from anywhere via the Comfort Cloud app. Compatible with Alexa and Google Assistant for voice commands.
• Stainless Clean Filter: The washable and stainless nanoe-coated filter captures allergens, dust, and fine particles while resisting bacterial growth. Annual professional cleaning is still recommended, but monthly self-cleaning is simplified.
• Cold Climate Heating to -4°F: Panasonic’s linear flow compressor maintains heating operation down to -4°F outdoor temperature with full capacity retention to 23°F. Ideal for moderate cold climates without requiring auxiliary backup heat.
