Number of heat settings
This refers to the number of pre-fixed temperature ranges at which the dryer can be used. For example, a regular cycle for heavy, durable, normal, everyday clothes requires higher temperatures than a delicate clothes cycle for synthetics, silks and sheers. More number of heat settings is good for those of you with a varied wardrobe of cottons, silk, synthetic, denim and so on.

Lint filter
This helps collect all the loose threads and lint that come off your clothes when drying. It ensures high efficiency of the machine and is also a must from the safety point of view as lint could lead to fire threat due to the high temperatures in the machine. When shopping for a dryer, ask for a sturdy, sizable lint filter that can be cleaned easily; a clogged filter decreases the dryer's efficiency and might also cause a fire.

Safety Reset
This feature will shut off your dryer if it gets overheated. It is a safeguard for your clothes and other fabrics.

Reversing action
The reversing action will ensure that the clothes don't get tangled. Here, the tumbling direction is reversed. This also helps dry clothes evenly and more efficiently. This is especially useful for large piles of laundry. A reversible door ensures ease of access in case you want to move the dryer to a new location.

Vent kit
A dryer vents hot air outdoors with an aluminium or rigid steel duct. There are hardly any ventless models available in India. These are very expensive with very limited choice.
