Filter Procurement for Green Star Projects: What Documentation Buyers Usually Need

Procurement for Green Star and other environmentally focused projects can move quickly once the mechanical design is settled, but filter buying often stalls on documentation. Developers, facility managers and mechanical contractors usually need clear, consistent product records before filters are approved, delivered or installed.

At Total Air Filtration, a family-owned air filter manufacturer and supplier in Hillcrest, Brisbane QLD, we see the same request patterns across commercial builds, fit-outs and upgrades. The exact paperwork varies by project, but the goal is usually the same: show what the filter is, how it fits, what it is made from, and how it should be handled on site.

Why documentation matters in green building procurement

Green Star projects and other sustainability-focused jobs often involve more stakeholders than a straightforward replacement order. The mechanical services engineer, head contractor, procurement team and building owner may all want to review the filter pack before purchase.

Good documentation helps buyers confirm:

• •the filter type and dimensions match the system
• •the product suits the intended application
• •the installation team understands handling and orientation requirements
• •the project file contains the records needed for handover and maintenance

For projects where the site requirements are still being confirmed, it is sensible to check the mechanical services engineer or building owner’s brief against the equipment schedule and the relevant ventilation design approach. If AS 1668.2:2024 is part of the project discussion, make sure the final selection is aligned with the site specification rather than relying on a generic catalogue description.

The core documents buyers usually ask for

Product data sheet

A product data sheet is often the first document requested. It should clearly describe the filter family, construction and intended use.

Useful items to include are:

• •filter size or nominal dimensions
• •depth, frame style and media type
• •primary application, such as pre-filter, final filter or specialist filter stage
• •airflow direction, if the product has a preferred orientation
• •temperature or moisture limitations where relevant
• •whether the product is disposable or reusable, if the design allows for that

If you are ordering to suit an existing housing, it can also help to cross-check dimensions with how to measure an air filter before the order is placed.

Performance information

Buyers commonly want the declared filtration rating or classification, plus the testing standard behind it. For many commercial jobs in Australia, this may involve MERV, EN 779, ISO 16890 or HEPA references, depending on the system and the design brief.

A few important points to keep in mind:

• •MERV, EN 779 and ISO 16890 ratings do not convert directly
• •G3, G4 and F5 to F9 are EN 779 classes and are still commonly used in Australia, even though ISO 16890 has superseded EN 779 in many contexts
• •if HEPA is specified, H13 is at least 99.95% and H14 is at least 99.995% efficiency at the most penetrating particle size under EN 1822

Avoid assuming that a similar-looking rating from another standard will satisfy the brief. The buyer may want the exact standard named in the mechanical specification or equipment schedule.

Installation and handling instructions

Project teams often ask for a simple set of handling notes so the filters are stored, unpacked and installed correctly.

This document may cover:

• •how the filters should be transported and stored before installation
• •whether the product must remain sealed until use
• •correct airflow direction and frame placement
• •how to seat the filter in the holding frame or gasket
• •what not to do during installation, such as forcing a mis-sized filter into place

If the filter is intended for a plant room, rooftop unit or tenancy fit-out, handling notes are especially useful for trades working across several packages at once.

What sustainability teams may look for beyond the product sheet

Green building procurement is not just about the filter element itself. Sustainability and procurement teams may also ask for supporting information that helps the project file stay tidy and traceable.

Common requests include:

• •material description, especially for frame and media components
• •product origin or supply details where the head contractor needs them
• •packaging information, if waste minimisation is part of the project brief
• •take-off support for the requested quantity and filter sizes
• •confirmation that the filters are suitable for the specified housing or frame system

Some filters are designed to be washable - check the product instructions before assuming a product can be reused. Where washability matters to the project, ask for the manufacturer guidance in writing so the site team can follow the correct process.

If the project includes replacement planning for ongoing operation, it can also help to discuss future servicing access early. Our filter servicing and commercial filter servicing pages outline the kind of support many facility teams look for after handover.

Submittals for custom or non-standard filters

Custom air filters are common in retrofit work, specialist equipment rooms and fit-outs where the existing housing is not a standard size. These jobs often need more documentation than a catalogue replacement.

For custom orders, buyers usually ask for:

• •dimensional drawings or a marked-up size confirmation
• •a clear description of the frame and media construction
• •approval of the selected dimensions before manufacture or supply
• •notes on whether the filter is a direct replacement or requires an adapter frame
• •delivery details that match the site access and staging plan

If the project uses unusual dimensions, multiple depth options or a non-standard frame profile, it is better to verify the measurements early. You can also review our products to see the types of filters commonly supplied for commercial systems, or go straight to custom air filters if the application is not a standard off-the-shelf fit.

Maintenance, replacement and handover documents

Green Star projects often end with a handover pack, and filters are usually part of that file. Facility managers in particular benefit from clear records because they support ongoing maintenance planning.

Useful handover documents may include:

• •product identification and part numbers
• •installed quantities and locations
• •basic maintenance notes for each filter stage
• •manufacturer instructions for inspection and replacement
• •guidance on monitoring pressure drop where gauges are fitted

Inspection frequency depends on the system, site conditions and dust load. The best approach is to follow the filter and equipment manufacturer instructions and monitor pressure drop where gauges are fitted, rather than relying on a fixed calendar schedule.

For sites with regular maintenance needs, keeping the original product data sheet and installation notes with the asset register makes future replacements much easier to manage.

Practical procurement tips for developers, contractors and facility managers

To keep the process moving, try to confirm the following before placing the order:

• •the exact filter sizes and depths required for each stage
• •whether the brief calls for a specific standard or classification
• •whether the filters must suit an existing frame, housing or bank arrangement
• •whether the project needs simple data sheets or a fuller submittal package
• •who will approve the final selection before manufacture or dispatch

If the job is still in design development, a short email exchange can prevent delays later. A clear schedule, site photos and the housing measurements are often enough to confirm what is needed.

For project teams working across several sites, it can also help to keep one point of contact for filter supply, sizing questions and replacements. That makes future reorders simpler and reduces the risk of mismatched parts.
