Why do I need an Air Filter?

Did you know that we spend 90% of our lives indoors? Did you also know that the air quality inside is frequently more polluted that the air outdoors? One cubic foot of indoor space has up to 300 million pollutants! All these pollutants can cause headaches, lung irritation, and fatigue and trigger allergies.

In addition to you and your family suffering, your heating and cooling system can also suffer. The filter helps keep the interior of your equipment clean. When dust and dander begin to build up in the system, heating and cooling efficiency can be reduced by as much as 25%.

The Aprilaire^® 2000 series air cleaners use a high efficiency Hepa-type filter which can capture dust, pollen, fungi, mold and pet dander. They capture 30 times more pollutants than ordinary 1" disposable filters.

The best part about the Aprilaire Central Air Cleaners is that they are completely out of sight and silent! The air cleaner is installed as part of your home's central heating and cooling system.

Advantages of a high efficiency pleated media air filter:

• Does not use electricity and thus will not produce an ozone odor.
• No moving parts.
• Filter components are not subject to mechanical failure.
• The only maintenance required is to change the filter once per year—easily done by the homeowner.

for the AprilAire^® High Efficiency Air Filters, Models 2200 and 2400 are available from our warehouse.
