LEZIFU Portable Air Conditioner Window Vent Kit — 5.9" Hose, Adjustable PVC Panels for Vertical & Horizontal Sliding Windows

LEZIFU Portable Air Conditioner Kit is an adjustable PVC window venting system with a 5.9" diameter hose and extendable panels that seal vertical or horizontal sliding windows to route hot exhaust outside.

This kit converts most portable air conditioner exhaust outlets into a tidy, energy-saving window vent. Built from durable PVC and supplied with plates, a 59" exhaust hose, an adaptor and sealing tape, the set is designed to stop warm air from re-entering the room and to simplify installation and storage. Check your unit’s exhaust diameter (around 15 cm/5.9") and your window or sliding door height before purchasing to ensure compatibility.

How does this kit reduce heat and save energy?

By directing the warm exhaust air out of the living space and sealing gaps around the hose, the kit prevents recycled warm air and helps the portable air conditioner reach set temperatures more efficiently. Better sealing means the appliance runs less often, which can lower electricity usage.

• Rigid PVC plates form a barrier against outside heat and drafts.
• Included sealing tape fills cracks around the window or door frame.
• 5.9" hose and adapter match standard portable unit outlets for a snug fit.

Which windows and air conditioners will this vent kit fit?

The system is built to suit most vertical and horizontal sliding windows and sliding doors, with plates that extend from 43 cm up to 160 cm (16.9"–63"). It connects to any portable air conditioner that has an outlet of approximately 15 cm (5.9") in diameter.

• Adjustable length covers narrow to wide openings, including sliding doors.
• Adapter and coupler filter match common 5.9" exhaust ports.
• Measure window height and hose outer diameter before ordering for assurance.

What comes in the box and how easy is installation?

The package contains two fixed plates, one adjustable plate, a 59" exhaust hose, an exhaust adapter, a coupler filter, sealing tape and three screws. The panels and hose use a simple slide-and-lock arrangement that requires no special tools and can be removed and stored flat when not in use.

• Contents: 2 x 43 cm fixed plates, 1 x 43 cm adjustable plate, 59" hose, adapter, coupler filter, 10 ft sealing tape, 3 screws.
• Tool-free setup with quick-fit connections; an installation video is available to guide the process.
• PVC construction allows folding and compact storage off-season.

How durable and reusable is the kit for long-term use?

Made from sturdy PVC, the panels resist deformation and aging so the kit can be reused across seasons. The material stands up to normal handling and compressive forces during installation, and the hose and tape are appropriate for repeated setup and removal.

• PVC resists cracking and keeps its shape after repeated use.
• Components detach easily for compact storage between cooling seasons.
• Replaceable parts (hose, tape, screws) allow quick maintenance if needed.

Who is this for: Ideal for renters, homeowners, and anyone using a portable air conditioner who wants a simple, affordable way to vent hot exhaust and improve cooling efficiency. If your portable unit has a roughly 5.9" exhaust port and your window or sliding door fits within the adjustable 43–160 cm range, this kit offers a reusable, easy-to-install sealing solution that keeps rooms cooler and reduces wasted energy.
