If you’re asking this question because you want to know in general if indoor air quality devices are helpful for your home, whether an air purification system or air filtration system, then the answer is yes. You may not absolutely need one, but we highly recommend it.
Most homes have unwanted contaminants floating through their air. It’s difficult to avoid because of the numerous sources of indoor pollutants and the way houses have strong insulation against outdoor air that limits fresh air circulation.
But if your question is more specific—you want to know if you should purchase either an air filter or an air purifier for your home—then our answer is you can have both—and maybe you should. We’ll explain in more detail below.
