About this file
This document is a Requirements and Specifications attachment (Attachment F) for Invitation for Bid (IFB) No. 304T-25-031A1 issued by the Texas Comptroller of Public Accounts Statewide Procurement Division for HVAC Air Filters. The solicitation covers 31 line items of air filters, including seven lines of bulk roll filter media (with dimensions ranging from 16 inches x 90 feet x 1 inch to 60 inches x 90 feet x 1 inch) and 24 lines of pleated air filters (with various dimensions between 12 inches x 24 inches x 2 inches and 24 inches x 24 inches x 4 inches). The filters are specified with MERV ratings of 5 or greater for bulk roll media and 10 or greater for pleated air filters, with precise performance requirements including synthetic dust arrestance and dust-spot efficiency standards.
The specifications detail comprehensive technical requirements for the air filters, including compliance with ASHRAE 52.2, UL 900, and AHRI standards. Filters must be non-allergenic, non-toxic, non-migrating, nonflammable, and odorless, with specific design requirements for frame construction, media composition, and performance characteristics. The procurement allows for case quantities of 6-12 filters, with explicit marking and certification requirements. The filters are intended for use in HVAC systems, with strict performance metrics tested at 295 fpm face velocity, ensuring high-quality filtration for state facility maintenance and operations.
