Why ULPA Filters?

ULPA (Ultra Low Particulate Air) filters are required in sensitive areas that require the highest level of air filtration. A ULPA filter meeting North American and European test standards can remove from the air a minimum of 99.999% of dust, pollen, mold, bacteria particles at 0.12 microns or larger. ULPA filters can also be used in conjunction with carbon filters to remove odours and VOC's depending on the needs of the OEM and their application.



The air filter standards that ULPA filters are tested to make them ideal for sensitive applications where ultra-pure air filtration is a necessity. They are not required in commercial spaces, homes, or schools – usually, HEPA filters meet these application requirements. ULPA filters are often used in applications where airborne particles are dangerous to human health or essential in manufacturing or assembly operations of sensitive equipment.

ULPA Filter Advantages



ULPA filters are able to capture the smallest ultrafine particles more efficiently than HEPA filters. ULPA filters are essential to achieve extremely low airborne particles counts required by ISO Class 4 or ISO Class 5 (or cleaner) cleanrooms. The additional cost and shorter filter life can make them uneconomical for everyday use.



In technology, manufacturing, and research facilities ULPA filters are typically utilized where the air quality is already extraordinarily clean. ULPA filters are highly-effective when placed downstream of pre-filters or HEPA filters. ULPA filters might be specified only for areas where already clean air is recirculated and refiltered. Staged filters ensure that the largest particles are removed by larger-pore filters early in the air supply stream. Prefiltering large particles upstream of the more delicate HEPA and ULPA filters can greatly improve the filter life and reduce energy consumption caused by backpressure.



ULPA filtered laminar flow hoods, isolation rooms, or containment systems can often provide adequate and localized air quality without requiring facility-wide HVAC renovations. When used in tandem, HEPA filters can provide a more economical and energy efficient air quality approach across large floorplans.



What do ULPA Filters Remove?



ULPA filters can remove from the air a minimum of 99.999% of dust, pollen, mold, bacteria particles at 0.12 microns or larger. These are particles that can pose a threat to sensitive assembly operations, people and the environment.



Where are ULPA Filters Used?



ULPA filters are often used in applications where airborne particles and pathogens are dangerous to human health or essential in the manufacturing or assembly operations of sensitive equipment. They are also used in environments that require ultra-pure air to remove the risk of contamination.

ULPA filter applications can include:



ㆍMedical research laboratories

ㆍPharmaceutical research and manufacturing

ㆍElectronics manufacturing

ㆍBiomedical air filtration and research

ㆍAirline cabin purifiers

ㆍCleanrooms

ㆍMedical facilities, like hospitals

ㆍBiological and chemical shelters
