Why low pressure drop is good:

The standard air cleaners on the market have filters that are very dense. Meaning they try to stop the dust by trapping it in a slightly porous filter. The fewer the pores the more dust it can trap. However, this not only stops the dust and dirt, but it also stops the air from moving as well. In other words, the amount of air that goes through your system is reduced so you may not be as comfortable. Less air is cleaned and less efficiently. This is called pressure drop. The revolutionary TRANE CleanEffects air filtration system has the lowest pressure drop with the highest efficiency possible. Our unique patented technology is designed to let air flow freely through the most advanced filtration system available. The result, more of your air is cleaned faster and more effectively than anything else on the market.
