My wife and I noticed that we began to sleep very poorly due to the fact that the air at home is bad and we decided to somehow refresh our room.
Well, I suppose the main problem is that your house has a poor ventilation system, and you're not the only one who has such a problem. Unfortunately, most houses in the US are full of polluted air because of cars, toxic factories, various pesticides, and so on. And yeah, I think it's time for us to use alternative energy sources. Anyway, one of the solutions to fix your current problem is to buy a good air purifier. In order to choose the best model I would recommend you to visit dehumidifiercritic.com as they have several helpful reviews on that topic.
