LG, Miele and Bosch all manufacture high-quality ventless dryers suitable for use in apartments. The best ventless dryer for a given apartment varies depending on specific needs, but it is worth checking out product reviews before making a purchase.
The LG DLEC855W compact ventless dryer is rated at 4 out of 5 stars, and features many of the benefits commonly found in larger models, including sensor drying and wrinkle care. It fits in a space only 24 inches wide, so it is ideal for most apartments.
Miele units can be pricier, but they are also highly rated in most quarters, and include models such as the Little Giant, a compact ventless dryer that can handle a 15-pound load.
