V-Cell Filters vs Pleated Filters: Choosing the Right Cartridge Style

If you are selecting filters for a commercial HVAC system, the choice between V-cell filters and pleated filters often comes down to how the system moves air, how much dust it handles, and how the filter frame is built. Both styles are widely used in Australian buildings, but they are not interchangeable in every application.

For facility managers and mechanical contractors, understanding the differences can help you match the filter to the equipment, the site conditions and the maintenance approach you want to support.

What sets V-cell and pleated filters apart

The key difference is the way the media is arranged inside the frame.

A pleated filter uses folded media in a flat or panel-style cartridge. The folds increase the amount of filter surface area compared with a flat panel, while keeping the overall shape compact.

A V-cell filter uses multiple pleated sections arranged in a V formation. This creates a deeper filter pack with more media surface area in the same footprint, which is why V-cell designs are often selected where higher dust loading or lower resistance is needed within the available cabinet space.

In practice, both styles can be made in different grades and sizes, and both can be supplied as part of broader our products ranges or as custom air filters when a standard size does not suit the frame.

Airflow and resistance considerations

Airflow is one of the biggest reasons to compare these two styles carefully.

Pleated filters are usually the simpler option and can work well in many HVAC systems, especially where the air handling unit was designed around a standard panel or compact cartridge. They can be a practical choice where access is tight and the system is not dealing with heavy particulate loading.

V-cell filters generally provide a larger media area in the same face size, which can help keep resistance lower for longer as dust builds up. That can make them attractive in larger air handling units, pre-filtration stages, and systems where maintaining stable airflow matters.

That said, the “better” option is the one that suits the fan, filter bank and operating conditions together. A filter with too much resistance for the system can create avoidable strain, while a filter that is too small for the dust load may load up quickly and need closer monitoring.

If you are working to a ventilation design under AS 1668.2:2024, site requirements should be confirmed with the mechanical services engineer or building owner before selecting or changing filter styles.

What to check before choosing

• •Available filter depth and frame space
• •The system’s fan capacity and allowed pressure drop
• •How much dust the site typically generates
• •Whether the filter bank is designed for a panel, cartridge or deeper V-style frame
• •Access for inspection and replacement

Dust holding and service life behaviour

Dust holding is another major point of difference, but it is not just about one filter “lasting longer”. It is about how the media loads and how the system responds as that loading increases.

A pleated filter has a straightforward structure, which can be ideal for lighter to moderate dust loading or as a pre-filter in a staged system. In suitable applications, the pleat pattern provides useful surface area while keeping cost and handling simple.

A V-cell filter usually has more total media area and more depth, which can increase its capacity to hold dust before resistance climbs to an unacceptable level. This is one reason V-cell designs are often used in more demanding environments or in systems where longer intervals between inspections are desirable, subject to actual site conditions.

Important point: inspection frequency depends on the system, site conditions and dust load. Follow the filter and equipment manufacturer instructions, and monitor pressure drop where gauges are fitted. That is the most reliable way to judge when a filter should be changed.

Typical applications for each style

The best cartridge style often depends on where the filter sits in the air filtration sequence.

Where pleated filters are commonly used

• •General commercial HVAC systems
• •Offices, schools and retail environments
• •As pre-filters ahead of finer stages
• •Plant rooms and packaged units with standard filter frames
• •Installations where straightforward replacement and compact size are priorities

Where V-cell filters are commonly used

• •Larger air handling units
• •Systems with higher airflow and deeper filter sections
• •Sites with heavier dust loading or more variable outdoor air conditions
• •Pre-filtration or intermediate filtration in multi-stage systems
• •Buildings where maintaining airflow through a deeper media pack is important

For many facilities, the decision is not either/or. A pleated filter may be the right pre-filter, with a V-cell design used in the next stage. In other systems, a pleated cartridge is entirely suitable on its own. The filter bank layout matters just as much as the media shape.

Ratings, standards and product selection

When comparing filter styles, it is easy to focus on the frame shape and overlook the rating. That can lead to mismatched expectations.

MERV, EN 779 and ISO 16890 do not convert directly, so avoid relying on rough comparisons between rating systems. G3/G4/F5-F9 are EN 779 classes and are still commonly referenced in Australia, even though EN 779 has been superseded by ISO 16890.

If a high-efficiency final filter is being considered, remember that HEPA ratings are specific and should be checked carefully. H13 is at least 99.95% efficiency and H14 is at least 99.995% at the most penetrating particle size under EN 1822. Those filters serve different roles from standard pleated or V-cell products and should be selected accordingly.

Some filters are designed to be washable - check the product instructions. Most commercial filters are not treated the same way, so do not assume a washable option simply from the appearance of the frame or media.

Maintenance, access and practical handling

Beyond performance, installation and maintenance matter.

Pleated filters are often lighter and easier to handle in smaller systems. They can be convenient where access space is tight and replacement needs to be quick.

V-cell filters are deeper and may offer better capacity, but they also need appropriate cabinet depth and enough clearance for removal and installation. In retrofit work, that physical fit can be the deciding factor.

For both styles, it helps to consider:

• •How quickly the filter bank can be opened and resealed
• •Whether the frame seals cleanly without bypass air
• •Whether the replacement media sits squarely in the housing
• •Whether the system can be checked visually and with pressure gauges, if fitted

If you are arranging ongoing support, filter servicing and commercial filter servicing can help keep the system on a sensible inspection program.

Choosing the right style for your site

There is no single best cartridge style for every building. Pleated filters are often the practical choice where simplicity, compact size and standard replacement are the priorities. V-cell filters are usually worth considering where the system needs more media area in the same space, better dust holding, or a deeper filter pack.

The right answer depends on the airflow requirements, the available cabinet depth, the dust load, and the broader system design. If you are unsure which style suits your application, it is better to match the filter to the equipment than to force a standard product into a non-standard frame.
