Understanding VOCs from New Furniture, Paint and Flooring

Newly completed interiors can smell different for a while, especially after furniture installation, painting, cabinetry work or new flooring. Those smells often point to volatile organic compounds, or VOCs, being released from materials as they settle into the space.

For homeowners, facility managers and builders, the challenge is knowing what is normal after a fit-out, what needs closer attention, and how to judge readings from indoor air checks without overreacting to a temporary odour.

What VOCs are and why they show up after a fit-out

VOCs are gases released by many common building and furnishing materials. They can come off new products slowly over time, especially when a space has just been completed and ventilation has not yet had long to flush the air.

Common indoor sources during fit-outs include:

• •Paints, primers, sealants and adhesives
• •Particleboard, MDF and other composite timber products
• •Carpet, vinyl and laminate flooring
• •Upholstery, foam and fabric treatments
• •Cabinetry, joinery and benchtop materials
• •Cleaning products used during handover and final clean

A fresh odour does not always mean a problem, but it is a useful clue. If the smell is strongest when the space is closed up, or after sunlight warms surfaces, that can indicate the materials are still releasing gases.

How to think about readings in a newly completed space

Indoor air readings in a new fit-out should be read in context. A single number, taken on its own, rarely tells the full story.

When reviewing readings, consider:

• •Whether the space has been recently painted, fitted out or cleaned
• •How long the area has been closed before sampling
• •Whether windows, doors and mechanical ventilation were operating
• •The amount of new material installed in the room
• •Temperature, humidity and direct sunlight, which can affect off-gassing

If a space has only just been handed over, elevated readings may simply reflect the materials used and the lack of time for ventilation to clear the air. Over time, readings often change as the source materials age and the space is flushed with fresh air.

It is also worth separating the idea of odour from the measurement itself. Some materials can produce a noticeable smell even when readings are relatively low, while other compounds may be present with little obvious odour.

Common gas sources in furniture, paint and flooring

Furniture and joinery

New cabinetry, desks, shelving and wardrobes often include composite timber products, glues and finishes. These can release gases from edges, cut faces and hidden internal surfaces, not just from what you can see.

If a room contains a large amount of new joinery, the smell may linger longer because there is more surface area contributing to the indoor load.

Paints and coatings

Painted walls, ceilings, trims and specialist coatings are common sources during fit-outs. Even when the surface feels dry, it may still be releasing odour while curing.

A strong paint smell after completion can be a sign that the area needs more time and better ventilation before it is fully comfortable to occupy.

Flooring and adhesives

Carpet, underlay, vinyl planks, timber flooring and floor adhesives can all contribute VOCs after installation. Floors can be a major source because they cover a wide area and can be warmed by sunlight, slab heat or underfloor systems.

If a flooring product is installed over a large open area, the odour may seem to come from everywhere rather than one obvious spot.

What site conditions can make VOC readings seem higher

A finished space can read differently depending on how it was completed and how it is being used.

Factors that often affect results include:

• •Poor natural ventilation or closed windows
• •Mechanical systems not yet balanced or commissioned
• •High indoor temperatures
• •Recent cleaning with fragranced products
• •Moisture in building materials
• •Large amounts of new furnishings placed in a confined area

This is why site-specific interpretation matters. A reading taken immediately after completion is not the same as a reading taken after the space has been ventilated and occupied for a period of time.

If the building is designed to operate under a mechanical ventilation strategy, site requirements should be confirmed with the mechanical services engineer or building owner. AS 1668.2:2024 may be relevant to the ventilation approach, but the right setup depends on the project and the way the building is used.

How filters fit into the picture

Air filters do not remove every gas, but they do play a role in managing airborne particles that may be present during and after a fit-out.

That can matter because new work often creates more than just gas emissions. There may also be dust from sanding, cutting, packaging, and general handover activity. Keeping the filtration system in good condition helps capture particles before they move through the space.

For gas and odour concerns, some systems use additional media or specialist stages designed for that purpose. The right setup depends on the application, the mechanical system and the site goals. If you are unsure what suits your project, our products and custom air filters can be a useful starting point.

Practical steps after a fit-out

If a room or building has just been completed, a sensible approach is to combine source control, ventilation and monitoring.

Useful actions include:

• •Keep the space ventilated as much as the building system allows
• •Remove packaging, offcuts and waste promptly
• •Avoid introducing extra fragrances that mask the odour without addressing the source
• •Check that supply and return air paths are not blocked
• •Inspect filters and system components according to the manufacturer’s instructions
• •Watch pressure drop where gauges are fitted, as this helps show when filters are loading with dust

Inspection frequency will depend on the system, site conditions and dust load. Follow the filter and equipment manufacturer instructions rather than relying on a fixed schedule.

If you are measuring the existing filter arrangement or planning a replacement, how to measure an air filter is a helpful reference.

When to ask for support

If a completed space still has a noticeable odour, keeps showing unexpected readings, or the mechanical system is not performing as intended, it is worth getting the setup checked. Builders may need to confirm what materials were used. Facility managers may need to review commissioning, airflow and filtration. Homeowners may need guidance on whether a smell is normal curing or a sign that more ventilation is needed.

People with health concerns should seek medical advice if they are worried about symptoms or reactions in an indoor space.
