1. Over 40 million Americans suffer from allergies and 17 million struggle with asthma

2. More than 1,500 hazardous substances may be found in the typical American home. What happens when you take this polluted air into your lungs? - Allergies, asthma, dizziness, sinus issues, ear infections, headaches, nausea, and respiratory infections. Indeed, about 50 million Americans suffer from allergies and asthma, and this equates to 9 million doctor visits per year!

3. Bacteria and molds promote poor indoor air quality.

4. Pets and tobacco smoke significantly contribute into indoor air pollution

5. According to the EPA, "indoor pollution can be as much as 100 times greater than outdoors."

Those particularly vulnerable to indoor pollutants include infants, people with heart, lung diseases and asthma. Additionally, anyone with extreme sensitivity to chemicals might want to seriously consider using an air purifier.

There are various types of air purifiers, so you can buy a purifier that fits your needs and wallet. The most common are:

HEPA Filters (High Efficiency Particulate Air): The air goes through a specially designed filter, cleaning 99.7% of the pollutants from the air. To understand how the HEPA process works, imagine a filter that only allows very tiny particles to pass through. If you placed a single sheet of this HEPA paper in front of a fan, very little air would be able to pass because of the small size of the holes.

Ionic Indoor Pollution Air Purifiers works by causing particles in the air to have a slight charge, particles are attracted to either a metal plate or to surfaces in the area. Most people are unaware that there are at least 4 different types of ionic air purifier in use today.

Ionizers have been around for many years. Have you ever felt like getting outside to get a breath of fresh air? Interestingly enough, some scientists point to +/- ions as part of the reason for outside air "feeling right". Combined with other methods, it can be extremely effective.

Carbon air purifiers: Activated carbon air filters consist of a system of pores that are tiny in size. These pores are highly absorbent, chemically reacting to particles that pass through them and the particles and odors actually bond with the carbon. Note that most carbon activated devices also incorporate HEPA technology, thereby combining the advantages of both types of technology

Ultra-violet Indoor Pollution Air Purifiers work by passing a ultra-violet beam through the air, which damages the DNA of biological pollutants affecting their reproduction system.

Ozone is a highly reactive oxidant that destroys certain bacteria, chemicals, bacteria and chemicals. Ozone Air Purifiers also reduce gases, odors, VOCs, and microorganisms.
