Usually, it’s the strength of the filter or the area of effectiveness. Nevertheless, even the budget options are often very good and bring a lot of portability and are still great for smaller rooms.

Portability

Do you want a purifier that will stay in one spot alone, or do you want to move it around your home and use it in various rooms? That’s an important question to ask yourself, and it will seriously impact the choice you make.
