Tired of hot, humid air blowing back into your room from your dryer or portable AC? The Mxclimate Dryer Vent Window Kit seals the deal – literally. This adjustable panel fits sliding windows or doors from 16.5” to 47” wide and works with standard 4” dryer or AC hoses. It comes with three sliding plates, a built-in outdoor vent cover (with a screen to keep bugs and leaves out), sealing tape, a hose clamp, and aluminum foil tape for a tight, leak-free fit. Made from sturdy PVC, it blocks rain, wind, and drafts while saving energy. Perfect for apartments, RVs, laundry rooms, or any space where you need to vent hot air outside without remodeling. Note: it won’t work on casement windows. Easy to install, even if you’re not super handy – just measure your window, slide the plates, seal, and attach your hose. Breathe easy knowing your air flow is efficient and your space stays comfortable.
