Sharper Image Air Purifier
The Sharper Image air purifier has certainly left it's mark with the introduction of the Ionic Breeze on the consumer market. The consumer market. That's you and me, the ones who are tired of the dust and odors and are worried about the safety of the air within our homes. Ionizers, ozone, HEPA. The alphabet soup of air purifying can be confusing. Let's take a look at some of what's going on.
The Sharper Image air purifier is a somewhat controversial product on the market today since it's an ionic air purifier. These devices work on the premise that pollution particles in the air tend to have a positive electric charge. If you add negative ions, or negatively charged chemical particles, to the air it is reasoned, the positive particles will be attracted to the ions, and they will bond. This process will effectively remove the positively charged pollutants from the air. Sometimes an ionic air purifier also produces ozone.
Ozone, by itself, has no ability to control dust or particles in the air. In fact, in high concentrations, it is a poison. It has become familiar because of talk of the destruction of the ozone layer.
The ozone layer is a layer of the earth's atmosphere that offers protection from the ultra-violet rays of the sun. Ozone is helpful up there, but it can be harmful down here. However, it does have the ability to kill mold and to neutralize odors, something like bleach. This is why an ionic air purifier sometimes generates it.
Some health experts write that the reason you feel refreshed after a rainstorm or when standing beside a waterfall is because the air in these places is filled with negative ions. An ionic air purifier is designed to produce this same effect. Ozone is thought to be one reason the air smells good when it is filled with ionic particles, so ozone generation is sometimes part of the package when an air purifier is designed.
Ozone has been used in hospitals for killing germs, and, according to some reports, there has never been a human death attributed to ozone use. However, other more conservative scholars warn against its use. They feel a HEPA air purifier is a better alternative to an ozone generating ionic air purifier. HEPA stands for High Efficiency Particulate Air and refers to a type of air purifier that works by filtration. Many vacuum cleaners contain HEPA filters for dust control. These help to clean the air when vacuuming. Air conditioners and dehumidifiers can also help control allergens and particles in the air.
An air purifier is often recommended for people who suffer from allergies or asthma. In fact, for these people it can be a lifesaver. One thing to remember, however, is that the Sharper Image air purfier can be pretty expensive, as can one of the HEPA varieties. A cheap air purifier probably will not control dust very well, so you should do your homework when choosing one. A high quality HEPA air purifier might set you back $400 or more.
A good measure to take with the Sharper Image air purifier or whichever air purifier you choose is to practice dust control the old fashioned way with good doormats. Much of the dust in homes comes in on people's feet. It's also important to keep cigarette smoke out of the home if you have people who suffer from asthma in the family.
