Twin Draft Guard is built for drafts first, but the gap under an apartment door is also where a lot of hallway sound and light come in, and this is the easiest way to close it. The Extreme model wraps two foam tubes, one for each side of the door, in a water-resistant microfleece cover with an adjustable hook-and-loop closure. It slides under the door with no tools and no adhesive, stays with the door as it opens and closes, and fits doors up to 36 inches wide, with tubes you can cut down for narrower doors. The maker says it blocks drafts, noise, dust and bugs. It only treats the bottom of the door, though, so the sides and top still leak, and soft foam does not seal as tightly as an adhesive seal kit. The maker's site sends buyers to Amazon and other retailers rather than listing a price, so our USD price check is pending.
