Breathe a Sigh of Relief: What You Need to Know About Air Purifiers

Clean Air, Healthier Life

While you might think you keep your home fairly clean, even using a robot vacuum cleaner to cut down on dust and dirt, you probably haven't considered the air quality. An air purifier eliminates the amount of contaminants in the air, helping to create a cleaner and healthier environment at home or at work.

Some of these contaminants could potentially harm our bodies and include viruses, bacteria, molds, pollen, pet dander and carbon-based impurities.

Air purifiers are helpful for people who suffer from allergies as well as breathing difficulties such as asthma. From commercial grade purifiers to standalone versions for the home, air purifiers have the capability to protect you and your loved ones from contaminants and pollutants.

How Do Air Purifiers Work?

Air purifiers have been around for close to two centuries, since 1830 when Charles Anthony Deane patented a device comprising a copper helmet with an attached flexible collar and garment. Purifying techniques have developed since, with better and efficient purifiers in the market. Here are different ways which air purifiers work:

HEPA Air Filters

HEPA is an acronym for High Efficiency Particulate Airfilter. These filters are very popular since they do not produce any ozone gases. HEPA filters are great for trapping smaller allergens like dust, smoke, chemicals, asbestos, pollen, and pet dander.

The filters are made of small glass fibers that meet the department of Energy standard of penetration of less than 0.03%, trapping 99.97% of airborne particles above 0.3 microns. HEPA filters are fitted with a fan that pulls air through streams of pleated filters to manually trap the contaminant particles.

UV Light Air Purifiers

UV light purifiers use Ultra Violet lamps to sterilize air through electronic radiation to kill bacteria and other pathogens. UV purifiers are most effective in getting rid of biological microorganisms as it creates an environment where bio agents cannot survive. However, UV purifiers cannot purify smoke, odors, allergens, or chemicals.

Ionizing Purifiers

These air purifiers work by using charged electrical surfaces to generate ions. The negative ions attach to positive airborne dust and allergen particles in the air. Ionic purifiers are very energy efficient, producing trace amounts of ozone. They also get rid of odors and smoke very fast.

There are two types: fan-based and fan-less ionizers. The only drawback is when all the surfaces are positively charged, particles from the ionic air tend to attach themselves to all surfaces in the room, including the floor.

UV AHPCO (Advanced Hydrated Photo Catalytic Oxidation)

This method was developed by NASA to purify the area in the space station from ethylene gases and other toxins. It features the latest and most efficient technology that includes high intensity UV light beamed towards a 5-metal hydrated catalyst cell. UV AHPCO gets rid of heavy metals, toxic gases, chemical pollutants and other Volatile Organic Compounds.

NASA’s patented AHPCO is also found in the healthcare industry, food industry as well as laundromats.
