It Enters Your Body 24 Hours A Day…And It Could Be Making You SICK

We all know how important nutritious food and clean drinking water are to our health. But rarely do we consider another major health factor we cannot see, touch, or taste: the air we breathe. Medical studies confirm that many people unknowingly breathe "sick" air in their homes and offices every day…air that contains common microscopic elements like pollen, dust mites, and bacteria.

As this polluted air is absorbed into our skin, lungs, and blood cells, it often causes or aggravates allergic reactions, headaches, fatigue, recurring colds, breathing difficulties, dizziness, nausea, and serious respiratory diseases.


Not all furnace filters are created equal so it’s not unusual to buy air filters thinking you have the right one only to find out the opposite after installation. The most common problem that incompatible furnace filters have is that they don’t fit. Improper-fitting air filters for furnaces don’t perform very well so that leaves you with improperly filtered air which can cause breathing problems for you and the people around you.
