When it comes to air filters, you get what you pay for. This is especially the case with the cheap flat-panel filters you can pick up at the supermarket for $3 or $4.

Finding an air cleaner that truly improves your indoor air quality is worth the time it takes to choose the right one. That’s especially true where pollen, pet dander, common household dust, dirt and even pollution is a concern.
