How to Explain Filter Costs to Strata Committees and Owners

If you manage a strata building, filter costs can be hard to explain when the difference between products is not obvious on paper. A practical way to approach the conversation is to focus on what the committee is actually buying: a filter that fits the system properly, captures the particles the equipment is designed to handle, and supports sensible maintenance over time.

At Total Air Filtration, a family-owned air filter manufacturer and supplier in Hillcrest, Brisbane QLD, we work with property managers and building teams who need straightforward answers, not technical jargon. The points below can help you justify filter quality, procurement decisions and upkeep in plain English.

Start with the purpose, not the price

When a committee asks why one filter costs more than another, it helps to move the discussion away from sticker price and towards function.

You can explain that a filter is not just a disposable item. It is part of the building’s ventilation or air handling system, and it needs to do three practical jobs:

• •fit the frame correctly so air does not bypass around the edges
• •capture the type of particles the system was designed to manage
• •work with the fan and equipment without creating unnecessary strain

If a cheaper filter is poorly sized, loosely made or the wrong construction for the application, it can create more issues than it solves. In strata settings, that can mean extra maintenance attention, nuisance complaints from occupants, and avoidable wear on equipment.

A simple way to say it is: the cheapest filter is not always the least expensive option once you include fit, performance and maintenance effort.

Talk about the building, not just the filter

Different buildings need different filter choices. A residential tower near busy roads, a mixed-use property with basement car parks, or a building with sensitive common areas will not have the same needs as a small low-rise block.

Useful talking points for committees include:

• •the location of the building and the amount of dust, traffic grime or outdoor contamination it deals with
• •whether the system serves common areas only, or also conditioning occupied spaces
• •whether the equipment has enough space and airflow capacity for the selected filter type
• •whether the building owner or strata committee wants a balance between initial purchase cost and easier maintenance handling

If the committee wants to understand the available choices, you can direct them to our products or, where the application is more specialised, custom air filters.

Explain quality in terms owners can see

Most owners do not need the technical details of media construction or pressure drop charts to understand filter quality. What they do need is a practical explanation of what changes when the filter is built better or specified more appropriately.

Things that are easy to explain

• •Consistent fit: A filter that matches the frame and equipment properly is easier to install and less likely to leak around the edges.
• •Appropriate media: Better media selection can improve dust-holding behaviour and support longer service between inspections, depending on site conditions.
• •Stronger construction: A sturdier frame or better pleat support can help the filter hold its shape in service.
• •Correct application: Some systems need coarse pre-filters, while others need finer filtration. The right choice depends on the equipment and the building.

You do not need to oversell the product. A clear statement such as “this filter is more suitable for this system and site conditions” is often more persuasive than a long technical explanation.

If a committee wants to measure existing filters before ordering replacements, point them to how to measure an air filter. Getting the dimensions right avoids delays and wrong deliveries.

Make maintenance sound like asset protection

Strata committees are usually comfortable with maintenance spend when it is explained as protection for a building asset rather than a recurring nuisance cost.

A good way to frame filter servicing is:

• •filters are inspected and replaced based on the system, site conditions and dust load
• •the manufacturer’s instructions for both the filter and the equipment should be followed
• •where pressure gauges or monitoring devices are fitted, pressure drop should be checked to help decide when service is due
• •blocked or deteriorated filters can affect how the system operates and may increase the workload on other components

This keeps the conversation practical. It also avoids making fixed promises about timing, because service needs vary from building to building.

If the committee prefers a managed approach, you can discuss filter servicing or commercial filter servicing so inspections, replacement and reporting are handled in a structured way.

Use standards carefully and without overclaiming

Sometimes owners will ask whether a proposed filter choice is “required by the standard”. The safest answer is to be specific and cautious.

You can say that ventilation and filtration needs should be considered in line with AS 1668.2:2024 where relevant, but the exact site requirement should be confirmed with the mechanical services engineer or building owner.

That statement does two useful things:

• •it shows the committee that standards are part of the decision
• •it avoids pretending that one product choice automatically suits every building

It is also worth clarifying that common rating systems do not convert directly into one another. If a committee is comparing MERV, EN 779 or ISO 16890 references, the safest approach is to compare like with like and get advice on the actual application rather than assuming a simple conversion. EN 779 classes such as G3/G4/F5-F9 are still commonly used in Australia, even though EN 779 has been superseded by ISO 16890.

Address procurement concerns before they become objections

Many strata committees are not resisting the spend itself. They are trying to avoid overspending or buying the wrong item. That means procurement conversations should answer a few simple questions early.

Questions worth answering in plain English

• •Why this filter type instead of the cheapest available option?
• •Does it fit the equipment as installed?
• •Is it suitable for the site conditions and dust load?
• •Is it easy to identify, order and receive the same item again?
• •Will it suit the maintenance process already used in the building?

If a committee wants a simple procurement pathway, the conversation can include whether stock items will do the job or whether a non-standard size or build is needed. In some buildings, custom air filters are the cleaner option because they reduce guesswork at reorder time.

You can also remind owners that some filters are designed to be washable, but only certain products are made for that purpose. Always check the product instructions rather than assuming a filter can be cleaned and reused safely.

Keep the explanation short, factual and repeatable

When you speak to a committee, consistency matters more than technical depth. A short, repeatable explanation helps everyone make decisions faster.

A useful script might be:

• •this filter is specified for the building’s system and conditions
• •better fit and construction help reduce avoidable maintenance issues
• •we are following the manufacturer’s instructions and checking condition as part of the maintenance plan
• •if the system changes or the site conditions change, the filter choice may need to change too

That style of explanation is easy for owners to follow, and it reduces the chance of the discussion drifting into guesses or conflicting opinions.
