HEPA Air Filters And Carbon Filters, How To Replace

Air Purifier Filtration Process:


Activated Carbon for Air Cleaning

Activated carbon is recognized as the safest and most efficient way to treat airborne chemicals, gaseous pollutants, fumes and odors. Carbon that is activated undergoes a process that opens millions of tiny pores and fissures to enhance the material's adsorbent properties.

A single pound of activated carbon typically has a surface area of 125 acres. In fact, activated carbon is so effective that it is used by the military to combat the world’s most dangerous airborne pollutants.


Super HEPA - Reinventing the HEPA filter

HEPA stands for high efficiency particulate air filter and describes a filter that can remove at least 99.97% of airborne particles 0.3 microns in diameter. Particles of this size are used to evaluate the performance of a HEPA filter, because they are among the most difficult to remove. True HEPA filters are composed of a dense web of fibers and are considered the safest and most efficient method to treat and eliminate airborne particles.

Super HEPA can filter out 99.99% of airborne particles 0.1 microns in diameter.

HEPA filters have essentially not changed in 50 years. While effective at trapping particles, they remain a fragile mass of fibers with a glue-like bonding agent, caged in metal to protect it from damage. We knew there had to something better. AllerAir has pioneered the use of Super HEPA. Our exclusive particle filter captures 99.99% of airborne particles and contains no bonding agents. It’s safe and easy to handle, cannot be damaged in transport and is safe for people sensitive to chemicals and odors.

UV Germical Lamps

Many of our units can be customized with a UV (ultra violet) germicidal lamp. This technology is favored by the healthcare industry, food storage warehouses, laboratories and other facilities where microorganisms, bacteria, viruses or mold are an issue. UV works by breaking down microorganisms and disrupting their DNA, hindering their ability to reproduce. 

When biological contaminants enter a home or building, they can quickly spread and may cause or aggravate health problems such as allergies, nausea, respiratory diseases and asthma. An air purifier with a Super HEPA filter and activated carbon can trap many of these contaminants, but an air purifier with Super HEPA filter and a UV light is even more effective.
UV disinfection is an effective way to decontaminate the air. The germicidal light breaks down harmful micro-organisms that pass through the rays, converting otherwise irritating pathogens, pollen and mold spores into harmless inert byproducts.
Ultraviolet light has been scientifically proven to reduce mold, fungus, viruses and other microscopic organisms that thrive indoors. It does not leave any residue or odors and the method has been used for decades by the medical industry to neutralize harmful micro-organisms. The food processing industry also utilizes UV light to keep bacteria such as listeria at bay.

Why Choose Activated Carbon Over Ozone?

Activated carbon the safe, effective and economical choice
  • Effective: Widely used by the military and heavy industry for chemical and odor control
  • Economical: Carbon canisters can be refilled, low electricity draw
  • Reliable: Simple, yet effective technology that is more reliable and easier to maintain
  • Safe: Does not create or aggravate respiratory problems, which makes it a safer technology for staff and clients during and after use
  • Versatile: Ideal for occupied buildings, can be used in any type of environment
  • Responsible: Does not create new pollutants
The drawbacks of ozone machines
  • Expensive to run, high electricity draw
  • Ozone must reach toxic levels to be effective against microorganisms, consequently ozone "blasts" are usually over Federal safety limits
  • Not suitable for occupied buildings
  • May cause serious respiratory problems for staff or clients
  • Not useful in high humidity environments
  • Oxidation can create other pollutants
  • Complicated maintenance, higher incidence of product or component failure
About Carbon Blends

Our standard “EXEC” carbon blend has a very large internal surface area and works exceptionally well for a wide range of air pollutants. 


The “Vocarb” carbon blend is our most recommended and best-selling specialty carbon blend. Vocarb stands for Volatile organic compounds or VOCs and this include a variety of chemicals that can cause a range of health problems including shortness of breath, headaches, fatigue, nausea, dizziness and eye, nose, lung and throat irritation. Some VOC's are suspected to cause cancer in humans and have been shown to cause cancer in animals. The long-term health effects caused by VOC's would depend on the concentration and length of exposure.


Some chemicals adhere better to different types of carbon materials and carbon blends. Over the years we’ve sourced and developed over 40 carbon blends. If you have an odor or chemical you need to remove, we have a blend to target it
