Air Filtration for a Restaurant Renovation While Trading Continues

Renovating a restaurant while service continues takes careful planning. Dust, odour and disruption can move quickly through dining areas, kitchens and back-of-house spaces if temporary air filtration is not set up properly, so the renovation needs to be managed as much like an operating environment as a building site.

With the right containment, filtration and sequencing, it is possible to protect active areas, support cleaner air paths for staff and customers, and keep work moving without turning the venue into a construction zone.

Start with a site plan that separates trading from work zones

The first step is to map the venue before any demolition begins. Identify where people will eat, where food is prepared, where deliveries come in, and how trades will move through the building. The goal is to keep dust-generating work away from active service areas and to create clear boundaries between the renovation zone and the trading zone.

Practical measures often include:

• •Temporary partitions or hoardings to isolate the work area
• •Sealed access points so dust is less likely to escape through doors and gaps
• •Dedicated entry paths for contractors and material deliveries
• •Temporary protection for counters, bar fronts, point-of-sale areas and kitchen equipment
• •A plan for where temporary filtration units will draw air from and discharge cleaned air

If the refurbishment affects the mechanical system, the site requirements should be confirmed with the mechanical services engineer or building owner, especially where AS 1668.2:2024 is relevant to the project.

Use temporary filtration to control dust while work is underway

Temporary air filtration can make a major difference during demolition, sanding, plastering, floor prep and joinery fit-out. The right setup depends on the size of the area, the type of work and how the venue operates during trading hours.

In many restaurant renovations, portable filtration units are used to capture airborne particles near the source or to clean recirculating air in the work zone. These units are often paired with temporary ducting, negative air arrangements or local extraction, depending on the layout and the scope of works.

Useful points to consider:

• •Place filtration units so they do not obstruct staff movement or customer flow
• •Position intake points close to the dust source where practical
• •Avoid directing dusty air toward dining areas, kitchen make-up air intakes or open doors
• •Check that temporary equipment does not create noise or draft issues that interfere with service
• •Confirm that the chosen filters suit the dust type being generated, whether from timber, plaster, concrete or mixed refurbishment debris

If a project requires a special size or frame configuration, custom air filters can help match the system rather than forcing a poor fit into a temporary setup.

Manage odour, grease and kitchen airflow carefully

Restaurant refurbishments are not only about dust. Odours from adhesives, paints, sealants, flooring products and demolition materials can travel through the site if airflow is not managed. In venues with active kitchens, the existing exhaust and supply air arrangement also needs attention so cooking air, renovation air and customer areas are not interfering with one another.

A practical temporary strategy may involve:

• •Keeping renovation materials sealed until needed
• •Staging odour-producing tasks outside peak service periods where possible
• •Maintaining separation between the kitchen exhaust path and any temporary air movement in the work area
• •Checking whether existing filters need inspection before and during the project
• •Monitoring pressure drop where gauges are fitted, especially when dust loads are higher than normal

If the venue already has commercial filtration equipment in place, commercial filter servicing can be useful before a renovation starts, so the system is ready for the extra demands of a live site.

Plan access, maintenance and change-outs around trading hours

A restaurant cannot usually shut down every time a filter needs inspection or a temporary unit requires attention. That makes access planning essential. Filter servicing should be scheduled around trading windows, kitchen production and contractor movements so maintenance does not interrupt service or create a new dust event.

Rather than relying on a fixed calendar alone, inspection frequency should depend on the system, site conditions and dust load. Follow the filter and equipment manufacturer instructions, and monitor pressure drop where gauges are fitted. If the filters are visibly loaded, damaged or airflow is restricted, they should be checked promptly.

Good servicing practice on a live hospitality site includes:

• •Keeping a spare set of the correct filters on hand where practical
• •Labeling filter sizes clearly so replacements are not delayed
• •Confirming access panels can be opened without disturbing the dining area
• •Coordinating with contractors so filter changes do not clash with demolition or sanding
• •Recording what was changed and when, so the team knows what remains in the temporary setup

If you need help identifying the right size or configuration, how to measure an air filter is a useful starting point before ordering.

Choose the right filter type for the task

Not every refurbishment task needs the same filter level. A light fit-out may need a different arrangement from a full demolition and rebuild. In Australian commercial projects, you may still hear references to G3, G4 or F5-F9 classes from EN 779, even though that system has been superseded by ISO 16890. These labels are still widely used in Australia, but they do not convert directly to MERV or ISO ratings.

For higher-efficiency applications, HEPA filters may be specified where the project requires them. If HEPA is relevant, H13 filters are at least 99.95% efficient and H14 filters are at least 99.995% efficient at the most penetrating particle size under EN 1822. Those ratings are only meaningful where the system is designed to use them.

A practical filter selection approach includes:

• •Using coarse prefilters to capture larger dust before it reaches finer stages
• •Matching the final filter to the temporary equipment and airflow available
• •Considering whether some filters are designed to be washable, and checking the product instructions before reuse
• •Replacing or cleaning only in line with the manufacturer’s directions

Keep the customer experience front of mind

In hospitality, a renovation is not only a building project. It is also a public-facing operation where noise, odour, dust and visible disruption can affect the way guests experience the venue. Temporary filtration helps, but it works best when paired with smart scheduling and clear communication between owners, builders and trades.

Consider staging the project so the most disruptive work happens when the dining room is quietest, and use barriers to hide the roughest parts of the work from customers where possible. Keep evacuation paths, amenities and staff zones clear, and review temporary airflow arrangements after each major stage of the renovation.

A simple checklist for live trading sites:

• •Confirm where air should be drawn from and discharged to
• •Check that temporary barriers stay sealed as the work progresses
• •Review dust levels after demolition, sanding and ceiling or wall work
• •Inspect filters when airflow changes or pressure drop increases
• •Reassess the setup if the scope of works changes
