Pocket Or Bag Filter

The Spectrum Pocket filter is a truly value added product that offers more value for money than any other filter in the Indian market. The high dust and high humidity ambient conditions in India provide a formidable challenge to any air filter. Practical usage has shown that our pocket filters have given effective performance of over one year in many installations. Pocket filters developed with 'STATE OF ART' Technology to replace conventional MICROVEE filters with reduction in Cost & Weight.

Progressive density media ensures that our pocket filters start at a very low pressure drop and gradual increase of pressure drop through the service life ensures lower power consumption and longer service life.


ASHRAE filters prevent airborne particles from moderate airflow volumes from polluting ventilation systems and also suitable as pre filters in a variety of applications. Spectra ASHRAE Filters are used by pharmaceutical, electronic product manufacturers as well as in nuclear power, atomic energy and research establishments. Approved by leading consultants, user industries & HVAC turn-key engineering companies, these are used for High level pre-filtration in Air conditioning of Paint booths, Air handling units, available in the range of 1to 5 micron.


HEPA filters remove a broad range of airborne contaminants, including fine dust, smoke, soot and pollen. HEPA filters are used in final filter applications including hospitals, electronics, nuclear, pharmaceuticals, laboratories, aerospace, food processing and optics. They can also be used as pre-filters in cleanroom environments and other critical applications.

High Temperature Filter

Spectrum High temperature (HT) air filter range offers from high temperature sliced media pad type or as framed box filters, This HT range has developed a filtration system to meet clean air environment at oven application.

Pad & Pleated Filter

Testing and certification for this range of filters has been sadly lacking in our country. For many years,and right upto the present time, efficiencies for this range of filters are reported in terms of BS 2831,which is an obsolete standard.Current international norms call for reporting of filters to be tested and evaluated in terms of ASHRAE 52.2, which specifies the rating of filters in terms of MERV (Minimum Efficiency Reporting Value). For the first time, filters are rated in terms of their efficiencies at a particular particle size, rather than in terms of simple gravimetric retention or dust spot efficiency. Spectrum is a pioneer in the installation of a test rig for the testing of filters in accordance with ASHRAE 52.2, and possesses a state-of-the-art facility for testing, evaluation and reporting of prefilters and intermediate efficiency filters. Spectrum also supplies prefilters and intermediate efficiency filters for various industrial applications, with media from Filtrair b.v., Netherlands, which is UL certified and certified for efficiency. Domestically available media are not certified, and their actual performance is therefore indeterminate. The Company thereby ensures that its products invariably satisfy client requirements with regard to filtration efficiency and dust holding capacity.

Gas Phase Or Chemical

Occupants of buildings where people work, play, live or recuperate are increasingly facing problem related to odor, VOC and other hazardous gases in the air we breathe. Recent studies have shown that Indoor Air Quality in commercial buildings can sometimes be 20 times inferior than outdoor air. Contrary to popular belief, air inside a building can be more hazardous than the air outside

Spectrum Filtration Pvt. Ltd. now introduces solutions to problems in the area of odor control, VOC abatement and other gaseous removal.

The Spectra Gas Phase / Chemical / IAQ is available in a wide range of standard filter sizes; they can be directly installed in an existing "Universal Holding Frame" filter bank. No expensive system modification is required to install these filters. When used in conjunction with "Spectra Pre" or "Spectra Fine" particulate removal filters, they ensure economical & effective removal of particulates, odors & gases.

Spectra Gas Phase / Chemical / IAQ filters are used to effectively remove odor associated with diesel fumes, hydrocarbons, tobacco smoke, body odors, cooking and Volatile organic compounds (VOC).

Specialty Filter

Spectrum picked up some unique products from entire range of products and categorized as Specialty filters for special application.


Holding Systems

Quality filter housings are as important as filters to ensure that the filtration systems integrity is protected. Housings should therefore be made to the highest specifications to ensure system integrity.

Spectrum offers a range of standard housings of various designs, to suit practically every type of filter, and end application. These housings are available in choice of materials, ranging from GI, powder coated MS, anodized or powder coated aluminium, and Stainless Steel.

Cartridge Filter

Cartridge filter can be capture particles and contaminant through the total thickness of the medium. Cartridge filters are normally designed disposable: this means that they have to be replaced when the filter is clogged.

Spectra Cartridge filters are ruggedly constructed to withstand extreme operating conditions; the Spectra - GT range of cartridge is available to fit almost all pulse & static installations.

Green Products

Spectrum green Filters has developed a line of Green Quality products that allows you to go green while lowering your costs and enhancing productivity in terms of save energy, reduce waste and Landfill Impact. In fact, these Green line of products can help you earn LEED credit points while actually reducing operating costs & do not burden on Environment.
