Indoor Window AC Cover for Winter - Upgraded Version - 21 x 15 x 3.5

About this item

• ADVANCED DESIGN: Featuring two side openings with adjustable Velcro flaps, this design allows air conditioner cords to easily pass through, whether positioned on the left or right side. When not in use, the flaps securely close to ensure a sleek, streamlined appearance.
• TRIPLE INSULATION: Our indoor AC cover, with its triple-layered composition of 210D PVC, POLYESTER FIBER PADDED, and 190T polyester taffeta, effectively insulates against wind and cold from entering and lowers heating expenses in winter.
• EASY SET UP - SIMPLE AND SECURE: No need for tools - just place the cover over your window air conditioner and use the built-in drawstrings to fasten it tightly. An additional exterior drawstring is also provided for extra stability, guaranteeing a snug fit to shield your AC unit effectively.
• SAVING ENERGY: Embedded with silk, our indoor air conditioner cover prevents warm air from escaping and blocks cold air from entering through the AC, thereby reducing heat loss and lowering heating expenses during winter.
• SUITABLE SIZE: With an inner dimension of 21” x 15” x 3.5” (L x H x D), it fits most window air conditioners or indoor AC units from 6000BTU to 8000BTU, specifically accommodating sizes between 19"-21" in length, 13"-15" in height, and up to 3.5" in depth.
