Key features

• Three-Layer Thermal Barrier - Built for Harsh Winter Winds: Unlike ordinary cotton covers, the AC covers for inside uses a triple-layer system - 600D waterproof, tear-resistant Oxford fabric, 2mm pearl cotton, and heat-reflective aluminum foil - for superior windproof warmth in snow and freezing winds. Care: Do not machine or hand wash. Wipe dust with a damp cloth and air-dry; avoid scrubbing or twisting to protect the inner foil insulation
• Please Choose the Right Size: The inner dimensions of this air conditioner cover indoor are 21"W x 15"H x 3.5"D, fitting most AC units with outer dimensions of ≤20.5"W x 14.5"H x 3.5"D. Note: Please measure your unit's width, height, and depth (including any protruding parts) before purchasing to ensure a proper fit
• Strong Hook-and-Loop Straps - No More Slipping: Unlike drawstring covers that tend to shift and slide around while you're putting them on, our indoor air conditioner cover features pre-sewn and adhesive-backed hook-and-loop straps for quick, fuss-free installation and a snug, airtight seal that blocks drafts effectively. The adhesive backing stays firmly on your AC unit, so when the cover is no longer needed, simply unfasten the straps and remove it - no need to re-peel the adhesive each time
• Cut Winter Energy Costs: This indoor indoor ac cover for window unit effectively blocks cold drafts and minimizes heat transfer during winter months, helping you reduce heating costs. Its insulated design creates a thermal barrier to keep warm air in and cold air out
• Two Closable Cord Holes: Our winter window AC covers indoor feature dual closable cable openings on both sides, allowing you to route the power cord from either side for added convenience. These openings also let you make slight adjustments to the cover's position for a tighter, more customized fit, while the closable design keeps the ports fully sealed against drafts
