The actual cost of a filter is only one element in the overall cost equation. The resistance of the filter has an effect on energy costs. Many times a switch to a different type of filter, even at additional cost, can result in big savings. We have the computer programs necessary to make these calculations.  

Our experienced sales team will perform an on-site survey of your current filter applications and make recommendations for changes or upgrades that will enable your facility to achieve the optimal filtration available for your systems. 

Blejwas Associates, Inc. offers filter maintenance programs for commercial, institutional, manufacturing and healthcare facilities. These programs consist of changing filters per ASHRAE and NAFA Standards or according to designated schedules. Scheduled air filter maintenance allows our technicians to inspect the filters and HVAC systems on a regular basis and to identify and remedy any problems that may arise. Following each service, a record of completion will be provided for your records.

Blejwas Associates uses NAFA certified NCT lead filter technicians at all of our customer sites to guarantee the highest quality filter program.  For complete customer satisfaction, our filter technicians are available 24 hours a day, 7 days a week to handle any emergency.​
