Keeping doors and windows closed for long periods can raise indoor carbon-dioxide levels and cause dizziness. Insufficient ventilation in a new home can also allow formaldehyde levels to rise and affect health. Haier has long focused on comfortable living, and its five-stage fresh-air purification system helped cumulative annual sales of Haier inverter fresh-air air conditioners exceed 55,000 units. Priced at under RMB 3,000, the Haier KFR-35GW also emphasizes value.The KFR-35GW brings in outdoor air at 20 m³/h, quickly increasing indoor oxygen levels. This airflow volume does not compromise cooling or heating performance, helping create a comfortable indoor environment and healthy breathing without opening a window.
Outdoor air often contains microorganisms, dust and other particles that can affect indoor air quality. The KFR-35GW addresses this with five filtration stages: an outdoor filter, an outdoor high-density filter, a HEPA purification filter, an indoor high-density filter and a silver-ion antibacterial layer. Together, they help deliver cleaner fresh air and remove harmful airborne contaminants.
In addition to its fourth-generation self-cleaning system, the KFR-35GW adds high-temperature disinfection lasting more than 30 minutes. The stated disinfection rate reaches 99%. The process cleans the air conditioner from the inside out, including the evaporator surface and outdoor unit, so the delivered air is cleaner.
