❄️ Lock in warmth, lock out the chill — your AC’s winter armor!
This indoor air conditioner cover features a robust three-layer insulation system combining waterproof Oxford fabric, 2mm thick foam, and reflective aluminum foil to block drafts and reduce heat loss. Sized to fit most window AC units measuring up to 21"W x 15"H x 3.5"D, it attaches securely with hook-and-loop fasteners for an airtight seal. Dual closable cord holes add convenience while preventing cold air infiltration, making it an energy-efficient solution to cut winter heating costs.
