If you are experiencing discomfort from allergies, one of the best things you can do is to purchase an air purifier. An air purifier will improve your indoor air quality and help alleviate your allergy symptoms. HEPA air purifiers filter a minimum of 99.97% of particles 0.3 microns and larger, including allergens and contaminants like dust mites, dust mite feces, mold spores, pollen and animal dander.

HEPA FILTER - WHAT IS A HEPA FILTER?

HEPA (High Efficiency Particulate Arresting) filters are the most efficient medium for filtering micron size particulates from the air you breathe. A true HEPA filter must capture 99.97% of contaminants 0.3 microns in size. Particulates this size are invisible to the naked eye but can be harmful when inhaled. Common allergens that fall into this category include pet allergens, dust mite allergens, mold spores, and pollen. Many air purifiers combine a carbon type filter for controlling indoor airborne chemicals, gases and odors. Household cleaning agents, personal care products, pesticides and paints produce these indoor pollutants. Maintaining cleaner air in your indoor environment reduces allergic reactions and should improve your overall health. The chance of having an allergic reaction to any of the above particles can be reduced by maintaining clean air in your living and work environments. By using an air purifier, you will find that you are breathing cleaner air and it will show in the way that you feel.

HEPA FILTER - WHY WOULD YOU NEED A HEPA AIR PURIFIER IN YOUR HOME?

We all are becoming more aware of the negative impact of "dirty air" on our health. Air Pollution not only triggers allergy and asthma attacks but can cause serious problems for people with heart, lung, and many other medical conditions. Poor air is especially harmful to the very young and very old. Unfortunately, bad air is not just an outdoor problem. According to the Environmental Protection Agency, indoor air is 5 to 10 times more polluted than the air outdoors. Fortunately, we can improve the quality of our indoor air with a HEPA filtered air purifier or air cleaner.
