A pre-filter is an integral part of almost any air purifier that you see on the market. It's the first stage of filtration, and it essentially helps to capture large particles. This prolongs the life of your filter, and it makes your system much more efficient.

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.
