I am doing a research project about the physics of indoor air quality and my subtoopic is electricity and polarity which is really only in air filters.

I am always getting stuffed nose and headaches indoors. My house is a newly constructed house. I am suspecting some gas is generated inside the house because its a new construction. Is there any instrument that is available which I can use to measure the indoor air quality? Can you please tell me where I can get such a instrument? If you guys have any other solution to resolve my allergies that will be great too.
