If you are looking to make the best air quality in your home there are a few things you can do.
The first is to have your home deep cleaned once a month by a professional cleaning service.
And if you live in an area that has generally bad air quality, that method is not going to do a whole bit of good, so you would have to go to more expensive and extreme measures. And that would be to buy a whole home air purification system and have it become part of your central heating and air conditioning system unit. It is a very high and hefty investment to make, but a whole home air purification system can more or less combat and destroy all bad air quality that sits in your home due to outside interference from the bad air in general. I have a whole home air purification system because this is what my local area is. It is very bad air quality most of the time. And with a whole home air purification system the air in my home is so clean you would think that you were living in mountain fresh air! I am not kidding on that bit. Even with the ultra bad air quality outside. Because I have both the whole home air purification system and I also have good insulation, it works real well. And maybe every so often I do have my house deep cleaned and my carpets cleaned to help keep the good air quality rolling from the whole home air purification system.
