If you live in an apartment in a major city, you likely have a window AC that was either a hassle to install or was there long before you moved in. If this is the case, the last thing you want to do is remove it, only to have to find a place to store and drain it during the winter months.

One of the best ways to completely avoid doing this is leaving the AC unit in the window and buying an insulated (even double-insulted) AC cover that fits snugly right over the indoor-facing part of the unit.

This tight barrier keeps any cold outdoor air from entering your apartment and keeps the indoor heat from escaping. Many options are available online, from Amazon to DTC air conditioner brands like Windmill Air and July. Best of all, these AC covers aren’t eyesores and actually blend in perfectly with most decor aesthetics.

To make picking the right one as easy as possible, we’ve rounded up the six best options below, with prices starting at just $7! Double-check your air conditioning unit’s dimensions to ensure they align with those of the cover you plan on purchasing.

1. Brivic Indoor Air Conditioner Cover For Inside Window Unit, $16.89-$17.99

This simple insulated indoor air conditioner cover has embedded cotton that blocks warm air from escaping and cold air from getting through the AC. It was also designed to prevent heat loss in the winter months and reduces heating costs.

Also, the inner lining near the air conditioner is made of water-resistant fabric. It blocks humid air from entering to keep your unit safe and dry. It also has a hole at the bottom corner to allow the cable to pass through with ease.

To ensure that it doesn’t budge, this cover has adjustable straps on both sides and elastic cords to let you achieve the tightest fit possible.

It comes in two colors (white and black) and four sizes.

2. FORSPARK Indoor Air Conditioner Cover With Free Drawstring, $16.79-$17.99

This cover also blocks cold air from entering the room and prevents warm air from leaking through to the outside. It’s made of 210D polyester/cotton and stops wind, rain, snow and insects from entering the AC unit to prolong its life.

It’s also machine-washable and reusable, and, much like the first option, it has two adjustable drawstrings on both sides for tightening and two holes on the bottom corner for the AC’s cable to pass through.

The FORSPARK Indoor Air Conditioner Cover comes in four sizes and two colors (brown and white).

3. Fujieco Indoor Air Conditioner Cover With Double Insulation and Drawstring, $6.99-$7.99

This super affordable option has double insulation to ensure that no cold air enters your home. It’s rain, water and snow resistant and sharply reduces heating costs throughout the winter months. It also blocks dust, dirt and other small debris from clogging your AC unit when it’s not in use.

It also has an elastic strip that’s sewn around the corner to ensure that it fits your AC unit as snugly as possible.

Fujieco Indoor Air Conditioner Cover comes in four sizes and one color (pictured above).

4. Bekith Indoor Air Conditioner Cover for Inside Window, $8.99-$11.99

This high-quality window AC cover is machine-washable and durable. Like the others on this list, it prevents dust, dirt and other small debris from clogging your AC when it’s not in use.

The embedded cotton blocks warm air from escaping and cold air from getting through the vents and into your home. This leads to reducing heating costs throughout the cold months.

There are also two holes at the bottom corner for the AC’s power cable to pass through and elastic edges with drawstrings for tightening for a custom fit.

Bekith’s Indoor Air Conditioner Cover comes in four sizes and one color (pictured above).

Particularly if you own a Windmill AC unit, you need to get this winter cover. It’s made of durable, water and mold-resistant cotton and protects against heat loss. It fits snugly around your unit and insulates it well to ensure that your room stays warm and cozy all winter.

This one also prevents cold drafts from entering your home through the AC’s top vents.

You also don’t have to use this cover exclusively for the Windmill AC unit. To ensure it fits your current air conditioner, confirm that the measurements align before purchasing.

6. July AC Indoor Winter Cover, $50

July’s double-insulated, cotton-polyester blend indoor cover lets you keep your air conditioner in all year long without worrying about cold drafts getting in or heat getting out.

It’s also machine-washable and is arguably the easiest to apply. Simply stretch it around the four corners of your AC, and it will fit in place — that’s it!
