The two most popular and efficient types of filters used in air cleaners are High Efficiency Particulate air filters, or HEPA filters, and electrostatic technology. Both of these systems are capable of removing particles, fumes, vapors and odors from indoor air at an efficient and timely rate. However, when hybrid technology is used and these two systems are combined in an air cleaner, the benefits and efficiency of the air cleaners is increased. When both of the technologically advanced systems work together to clean the air the chances of catching the particles in the air before it exits air cleaners and circulates through the room are doubled.
BlueAir is the brand of air cleaner that has experimented with hybrid technology and shown the air cleaning market how effective and efficient this technology can be. A BlueAir cleaner is equipped with a complete HEPA filtering system and also includes electrostatic wands inside the air cleaner. These wands are able to attract the particles and give them a charge before they are passed onto the HEPA filter. By having this charge present on the particles, they are attracted more easily to the filter. The electrostatic wands help the HEPA filter to attract all particles in the air. The HEPA filter is more efficient and does not have to work as hard with the electrostatic wands present. BlueAir created this hybrid technology not just for its effectiveness in cleaning particles in air but also for other health benefits.
The air purifiers made by BlueAir that possess hybrid technology are proven to reduce ozone levels in indoor air. In third party tests, it was found that the ozone levels in the air when the BlueAir air cleaner was performing were decreased. The air cleaners that were designed with hybrid technology to include both HEPA and electrostatic media also are found to be less noisy. Most air cleaners that only use HEPA technology have to make the fan inside work extra hard to push air through the filter. In the BlueAir air cleaners, the air moves freely through the air cleaner, which reduces the power needed by the fan. When the fan is on a lower power, the sound made by the air cleaner is reduced. The filters are also designed to stay cleaner longer than in regular air cleaners. Since both systems of cleaning are used, the buildup of particles on the filters is a lot less than if there was only one system used. Since the filters are able to handle more particles without build up, they do not need to be replaced as often as an air cleaner that uses only a single system.
The material used in the HEPA filter inside a BlueAir air cleaner is made of polypropylene filter media. This filter media is non-toxic and does not omit any harmful gases when the unit is performing. There is no outgassing that occurs when the unit is used and no fibers are shredded into the air like some other types of filters. The air is passed through the pleated HEPA filter where any bacteria or mold that may have been present in the air is eliminated. The air is then passed through the electrostatic media. By using the static charge, this media is able to catch any particles or bacteria that may have been missed by the HEPA filter. The filter media itself does not have to deal with the electric charge. It is only the particles coming through in the air that are charged. By not dealing with any charges, the filter is able to stay efficient longer. With the use of the hybrid technology, a BlueAir air cleaner is able to remove particles, gases, odors and fumes from indoor air.
This hybrid technology proves its effectiveness by having the ability to absorb 99.7% of all particles that are 0.01 microns and larger in size. Most air cleaners that only use one system are only able to detect particles that are 0.03 microns and larger. BlueAir has discovered that by combining both technologies, an air cleaner can become a lot more effective and efficient. These air cleaners are able to absorb a greater amount of smaller particles by using both a HEPA filter and electrostatic media.
