Everyone has seen the acronym HEPA. But do you know what it stands for? It stands for High Efficiency Particulate Air. Now you are probably wondering what that means. It means that HEPA air purifiers are capable of filtering out 99.97% of all particulates that are 0.3 microns or greater in size. A human hair is 300 times too large to break through a HEPA filter! The HEPA filter was created by the US Atomic Energy Commission to filter out sub-micron particles during World War II.
The HEPA filter used in air cleaners and purifiers are the most reliable on the market. They have been proven to drastically improve the indoor air quality of any space It is essential in purifying the air and ridding your environment of common allergens: such as pollen, mold, dust and dust mites.
It works as an exchange of air. Essentially what happens is allergens (particulates) are sucked into the HEPA filter where they get stuck. Then only the clean air is returned into the indoor space. You exchange contaminated air for clean air. This happens numerous times as the air is exchanged, thus resulting in better, cleaner air qualities. The higher the exchange rate, the cleaner the air.
It is important to note that these products work only in the room in which they are operating. It does not exchange air through walls or wide open spaces. It will clean the air in the room in which it is placed. In order to achieve optimum results, the machine should not be placed directly against a wall. You want to increase air circulation. It is also helpful to close the door to the room. This is especially helpful in the bedroom while sleeping.
Another important feature in these products is ultraviolet light systems. These systems remove viruses, bacteria, and mold spores. All of which are incredibly harmful to the human system. So it not only protects us from dust and pollen but also viral contaminants in the air. It is important to mention that these machines do not produce any harmful substances such as ozone or ions. Ozone can be dangerous to the human body because it is an active oxygen.
These products are efficient, durable, and well-built. Most machines have at least 3 speed motors, steel construction (prevents annoying rattling machines), and warranties. There are several different models depending on your needs (allergens, asthma, pet dander etc).
They also require minimum maintenance, all you have to do is vacuum the four sides of the outside screen with vacuum brush once a month.
Our health is invaluable. If you want better sleep and less allergy and asthma symptoms then a quality HEPA air purifier just might be what you need. It is crucial that we live in environments with clean air and protect ourselves from environmental contaminants and viruses. HEPA air purifiers were designed to prevent the spread of airborne radioactive contaminants! So it is pretty safe to say that it will help tremendously in providing an allergen free lifestyle.
