For outside, I use a 3M rubbery mask (https://www.amazon.com/gp/product/B008MCUT86) along with P100 filters (https://www.amazon.com/gp/product/B007STCT00).
You could also use any of 3M's N95 disposable filters. They look a bit better, but you have to be more careful about getting a good seal when you put them on.
For home, you need to ensure your windows and doors have good seals. Then you need an air purifier (and to regularly change its filters). If you are on a budget, consider this one: http://smartairfilters.com/in/en/product-category/diy/
If money is no object, then get the IQAir Healthpro 250.
