- What is HEPA?
HEPA Filters were developed by the Atomic Energy Commission during World War II to remove radio active dust from their plant exhaust. HEPA Filters (HIGH EFFICIENCY PARTICULATE ARRESTANCE) are now the primary filtration systems for electronic clean room assembly, isolation wards, surgical theaters, bioengineering, pharmaceutical processing, and any application where maximum reduction or removal of sub micron particulate is required.

- 99.97% free of particulates
HEPA filtered air is 99.97% free of all particulate down to 0.3 microns (including bacteria, fungal and other opportunistic micro biological). Because of this, HEPA is rapidly coming into many medical applications such as isolation of patients under treatment involving immunological isolation, care for burn victims, orthopedic surgery, etc.| Back |
- Interception family
Generally, HEPA Filters belong to the 'interception' family of filters and are variously referred to as 'absolute' super interceptor, and so on. Such filters have a deep bed of randomly positioned micro glass fibers, in which the total bed depth (thickness of media) is very large in comparison to the average fiber diameter and effective pore of free path cross section.
- Tortuous path, twist and turns
Even though the media may be only 1/16 " thick, this is an enormous distance compared to the 0.s to 1.0 micron diameter of the fibers. The passages through which air must flow are not straight, but are very tortuous, with many twists and turns. As particulate impact on the fibers and adhere to them, the passages become smaller and the filter increase in efficiency.
The HEPA filter maintains its efficiency over it's two (2) to five (5) years of life. It is 99.97% efficient by particle count down to 0.3 micron, which is 1/75,000 of an inch, or 1/300 the diameter of the human hair. It becomes more efficient both above and below the 0.3 micron particle size.| Back |
HEPA does not require any cleaning or maintenance to maintain this efficiency. Because all respirable particulate including bacteria, fungi and other minute airborne contaminants are trapped in the HEPA filter, the use of HEPA filtration, when properly applied, will significantly eliminate or reduce the deleterious health effects of airborne contaminants on the respiratory system. | Back |
- More efficient
HEPA filtration is 40% more efficient than the highest efficiency rated ASH RAE filter.

Unique Allerair Air Filtration System Features
- Metal housing
most off the shelf air cleaners, purifiers, filtration systems are housed in plastic that off-gas plastic vapors
- Glueless felt gasket
most other air cleaners, purifiers, filtration systems use glued rubber gaskets that give off odors, vapors, fumes
- American made motor
high quality motors assure trouble free running, low power consumption (average 60 watts)
- Separate HEPA filter and Activated carbon / charcoal filter
can be changes at different intervals, savings on filter replacements
- Warm rolled HEPA filters with separators
avoids cracking at the folds and keeps the folds open over the life of the filter
- Easy change pre-filter
pre-filter can be removed, cleaned, replaced in 30 seconds ( half a minute)
- 2 Anti-Microbial filters
the activated charcoal / carbon filter is wrapped in two (2) anti-microbial filters to suppress any microbes around the filters
- Dual air flow system
air enters vertically at the bottom and exits horizontally at the top, avoids mixing and increases effective cleaning range
- Cylindrical shape
maximizes air filtration and avoids stale air in corners
- UV Lamp / Light option
UV (Ultraviolet) light / lamp/ bulb sterilizes airborne pathogens antigens
- 40 Special blends of activated carbon / charcoal available
correct blend of activated charcoal / carbon for specific chemical and VOC (volatile organic compound) problems

In most studies that investigate the association of mold or water damage and respiratory disorders in infants, the analysis is not adjusted for exposure to house dust mite (HDM), which is also a known cause of respiratory illnesses.
To investigate the relationship between visually observable mold or water damage and HDM (Der f 1) levels and the prevalence of lower respiratory tract symptoms and allergen sensitization in infants of atopic parents as part of a prospective birth cohort study.
On-site home visits (at the infants’ age of 8 months) were performed to evaluate observable mold or water damage and HDM exposure. At a clinic visit near the infant’s first birthday, medical histories, including parent-reported wheezing episodes, and a skin prick test to food and 15 common aeroallergens were conducted in 640 infants.
More than half of the homes were found to have mold or water damage, and 5% had major mold or water damage with visible mold at 0.2 m2 or more. Only 16% of homes had a HDM allergen (Der f 1) concentration of more than 2 μg/g. Major mold or water damage increased the risk of recurrent wheezing nearly 2 times in infants, 5 times in food or aeroallergen-sensitized infants, and 6 times in aeroallergen-sensitized infants. Neither visible mold or water damage nor HDM exposure was associated with sensitization to either mold or aeroallergens.
Visible mold was shown to be a significant risk factor for recurrent wheezing in infants at high risk of developing atopic disorders, whereas HDM exposure did not significantly increase the risk.
