We recently did a Twitter live session with Amit Grover, the Head - Learning & Development, DSP Mutual Fund on the right way to invest in Equity Linked Savings Schemes (ELSS) or tax-saving mutual funds. When you invest in an ELSS mutual fund, you can claim a tax deduction on investments up to Rs 1.5 lakhs and you can save up to Rs ₹46,800 in taxes. 
In this chat, Amit answers:

What are ELSS funds and how do they work
For how long should you invest in an ELSS mutual fund
ELSS funds vs other tax saving options like PPF, tax-saving fixed deposits etc
How to analyse an ELSS fund
