So what makes a great in home air purifier?

Many of the top air filters or air purifiers start with a HEPA (High Efficiency Particulate Arresting) filter. HEPA filter fabric does not look like a screen or a piece of cloth. Instead it looks like a very thin pad of fibers. HEPA filters force air through this maze of fibers; the denser the fibers the smaller the particles are that get trapped. There are three ways the HEPA filter stops particulates. First and the easiest to understand is that a particle runs into a fiber and sticks. Secondly, the particle gets within one diameter of a fiber of the HEPA filter and while it tries to pass the fiber it is gets stuck. Third, as a very small, about 0.1 micron, particle moves in the gas flow creating collisions with molecules (Brownian motion) and again happens to slide close to a fiber and get caught.

HEPA filtration was developed in 1950 by the US Atomic Energy Commission. USAEC needed something to remove small particulates that are radioactive. Since then HEPA air purifiers have been using this technology to clean the indoor facilities. HEPA products are also one of the many techniques and products used by Allergy and Asthma doctors to help alleviate the symptoms of those conditions. So this is the first component needed to create a great air purifier.

One of the newer components of a good system is the use of Ultra Violet Light or UV. UV is effective in killing organisms such as bacteria and viruses. It achieves this by mixing up the DNA of the organism. This molecular change makes the organism loose its components that make people sick. There are two wavelengths of UV light that are best absorbed and thus most effective at killing microorganisms. These are 185 nm and 265 nm. This means that for a UV lamp to be effective killing microorganisms it must emit energy in or around one of those wavelengths.

While UV technology is excellent at destroying viruses and bacteria it should not be uses without a particulate filter system ahead of the lamps. Without a particulate filter system too many microorganisms may be shaded from the light by particulates. Therefore, most air purifiers that employ UV start by filtering the air with HEPA and use the UV as a final stage of filtration. The combination of these two components makes for a more effective air purifying system. But we need to add one more component to get the most from any air purifier.

Combining an Ozone system or Ionizer helps eliminate the odors in the air. Carbon filters help with this but the Ozone system woks much better. Ozone is an unstable oxygen molecule (O3) that oxidizes anything it bumps into. This is great for removing odors, killing mold and mildew. So, if a home is flooded or has a sewage backup this technology is often used by professionals to help clean up the mess.

Many believe that Ozone systems are not good or harmful to people and animals. This may be true if the system does not have an Ozone safe certification. So be sure to do your research before buying.

Alen Corp has developed a system with all of these components and has received the Respiratory Product of the Year award. This is a description of the Paralda Air Purifier from Alen Corp.

“With the release of the Paralda air purifier, we've begun redesigning air purification! With the Paralda air purifier you can breathe the cleanest air possible without sacrificing the style of your home. Named after the elemental king of air, the new Paralda air purifier is redefining air purification with its design, function and ecological commitment.

The Paralda air purifier has multi-filtration technology contains HEPA filtration, an ozone safe Ionizer and a long-lasting ultraviolet light. The HEPA filter in the Parlada air purifier has been tested to remove 99.42% of airborne particles like dust, dust mites, pet dander, mold spores and pollen. The long-lasting UV light in the Paralda air purifier has proven to eliminate 98% of airborne bacteria and viruses. The Paralda air purifier combines the ozone-safe ionizer which promotes an environment of health and rejuvenation.

The Paralda air purifier is green - literally. The translucent exterior poetically suspends the bamboo green interior portraying a feeling of freshness. The Paralda air purifier is also green, in design; it's RoHS compliant, Energy Star qualified and ozone safe”.

Why do we need air purifiers?
It has been proven time and time again that indoor air is often dramatically more polluted than outdoor air, these studies vary depending who is conduction them. Indoor air pollution comes from a variety of sources like pets, plants, mold spores, fungi spores, house dust mites, chemicals used in cleaning, off-gassing of carpets, furniture, and upholstery, and pollens. The reasons are yet to be determined, but in recent years there has been a dramatic rise across the planet of people reporting the onset of seasonal allergies in their lives for the first time. Indoor air purifiers can help people to sleep better and to deal more effectively with environmentally induced stresses such as seasonal allergies.

The Paralda is extremely quite and will clean the air for 400 square feet. Do yourself and your family a great service and get a Paralda Air Purifier today. Healthier, safer and better smelling air in your home will make the whole family happy.
