Standard air cleaners have filters that are very dense, so they 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. So you may not be as comfortable, and less air is cleaned efficiently. This is called pressure drop. The revolutionary Trane CleanEffects™ air filtration system has the lowest pressure drop with the highest efficiency possible.
Now you can screen out indoor air contaminants with the Airscreen 1000 electronic air cleaner. Most homes in North America are 5 to 10 times more polluted than the outside air. When dirt settles on your skin, you can wash it off. When it settles in your lungs, it can cause a wide variety of respiratory problems.
