Filter test report packages, assembled from lab and plant records for your quality manager.

The records behind a lot live in different places: lab sheets and third-party reports, production records, media receiving records, pressure drop logs and whatever the customer's order said it wanted. Someone in quality pulls them together, checks that each page belongs to this lot and this construction, and works out what the customer asked to see.

In the test, AI works from copies of those records and assembles a draft package: the named test method and edition, the efficiency rating as reported, pressure drop readings with their flow and units, the media lot, the certificate requested in the customer's own words, and a list of what is missing. Your quality manager reviews each one beside the package your team actually shipped. Nothing is signed or sent.

A buyer can spell out what a report must hold. North Carolina's air filter specification lists eleven items for a third-party ASHRAE 52.2 report, among them the test air flow beside the maker's rated air flow, initial and final resistance at rated flow, how the laboratory came by the sample, who the laboratory is, test dates with signatures and the measured gross media area. The data has to describe a complete filter from current production, frame and media support included, not media on its own, and the state may pull its sample from a customer's delivered stock. UMBC's 2024 bid wants a report from an independent laboratory on each filter. The draft maps every item on a customer's list to the page in your file that answers it and writes not found where nothing does.

The method decides the report's shape. The National Air Filtration Association's guide describes particle counts across twelve size ranges in six test cycles, the lowest values forming a composite minimum efficiency curve, and three averages, E1, E2 and E3, that set the MERV. Dust holding capacity comes with it, and NAFA cautions that the figure shouldn't be used to work out expected life. One lab's published outline of its 52.2 report lists the filter description, test parameters, clean and dust-loaded efficiency data and the clean filter's pressure drop curve across air flows. The draft carries each as reported. It calculates nothing and decides no rating.

The edition on the report changes what its numbers mean. ASHRAE's errata to the 2012 edition has final resistance chosen from a table as a minimum and never less than twice the initial resistance. NAFA's guide to the 2025 edition says designated final resistance values have been removed, that a calculated release rate replaces the old shedding penalty for filters that release particles, and that the test humidity range is narrower. North Carolina and Michigan both cite the 2012 edition by year. So the draft shows the edition printed on each report next to the edition the customer named and flags a difference without calling it a problem.

High-efficiency and baghouse files have their own vocabulary. IEST-RP-CC001.7 describes eleven levels of filter performance and six grades of construction and says a purchase order should name both; its type letters don't run in sequence, so a letter alone tells a reader little. IEST-RP-CC034 covers leak tests in the factory, at the job site before installation and after installation, and a report has to say which it records. Michigan's master specification has HEPA cell sides marked with maker, style code, serial number, efficiency and resistance. On baghouse fabric, an EPA technology verification statement signed in 2011 describes sample swatches marked with model number, year and month of manufacture and cake side, reports outlet concentration, residual pressure drop, cycle time and mass gain, and applies only to media made within three years of signature. The draft ties each reading to the serial number or media lot your records show.

Liquid lots use other words, and one rule reaches the housing. ISO 16889's multi-pass test yields a series of Beta ratios rather than one efficiency figure, at particle sizes written as µm(c) to show how the counter was calibrated. Under EPA's 40 CFR 141.719, challenge testing of bag and cartridge filters for drinking water credit runs on full-scale filters and housings identical in material and construction to those the system will use, challenges each filter at three points in its cycle, expresses results as log removal values and is repeated if the filter is changed in a way that could alter its removal. Your reviewer will check that every page belongs to the lot, every reading matches its source, and the missing list caught what your team actually had to chase.

With your reviewer's yes, the next lots that need customer documentation go through the same assembly for about 30 days.

Your quality manager reviews and signs every report before it leaves, and any decision about a result stays with quality. Comparison carries on against live packages. A next job is priced on its own, and monthly support comes after that.
