The snake plant: tolerant of low light levels and irregular watering. As a matter of fact, during winter it only needs to be watered every couple of months. NASA found the snake plant to be one of the best plants for improving indoor air quality.
SNAKE PLANTS don't need much light or water to survive. The plant absorbs carbon dioxide and releases oxygen during the night (while most plants do so during the day), so add one to your bedroom for a clean-air boost.
