OPEN YOUR WINDOWS!!! Let fresh air permeate your home. Open the windows! Add houseplants too! They can help clean the air inside your home! I find that a nice smelling home is important and one step is opening the windows and letting fresh air in. Takes any stale air out.
Some good plants:
Ferns
Snake Plants
Rubber plants
Aloe Vera
Spider Plants
Gerber Daisy
