Why Passive Air Care Is Replacing Aerosols in Commercial Facilities

Odour control is one of the fastest-growing segments in commercial facility management across Australia. The B2B air care market reached 48.43 million in 2024 and is projected to hit 67.21 million by 2033, with much of that growth driven by demand for sustainable, low-maintenance products. At the centre of this shift is passive air care, a category of air fresheners that is steadily replacing traditional aerosol spray systems in hospitals, offices, aged care facilities, and hospitality venues.

The reason is operational. Aerosol systems require batteries, generate waste, and deliver fragrance in inconsistent bursts. Passive air care systems work without any of that. They release fragrance continuously through controlled diffusion, run without electricity or moving parts, and need servicing only a few times per year. For facility managers responsible for keeping washrooms, lobbies, and shared spaces clean and welcoming, the difference in daily performance is significant.

The Problem with Aerosols in Busy Facilities

Aerosol air fresheners use batteries and a spray mechanism to push fragrance into the air at timed intervals. While they can temporarily mask bad odours, they create a few operational headaches that facility teams are keen to solve.

The biggest issue is inconsistent coverage. Each spray creates a peak of scent that fades quickly, resulting in a cycle of strong-then-weak fragrance throughout the day. People entering a washroom between spray intervals may encounter exactly the odours the system was meant to control. According to a survey, 94% of people would avoid a business in the future if they encountered dirty or bad-smelling restrooms. When air fresheners leave gaps in coverage, the impact on customer perception is immediate.

Restocking adds more variability. Aerosol cans run out at different rates. Batteries need replacing. Each dispenser across a building becomes its own maintenance task. When staff miss a unit, the gap is immediately noticeable to visitors.

There is also growing scrutiny around indoor air quality. Scented spray products can emit volatile organic compounds (VOCs) during operation. Many facility managers now prefer solutions designed without propellants altogether, helping keep indoor air clean and reducing chemical residue on surfaces, air filters, and upholstery.

What "Passive Air Care" Means Operationally

A passive air freshener is an odour-control system that operates continuously without batteries, electricity, or mechanical parts. Instead of spraying scent at timed intervals, passive air care systems use controlled diffusion and natural airflow to release fragrance gradually from a sealed refill. The result is a consistent, continuous scent from the first day to the last, with no sudden bursts that cause scent fatigue.

For facility teams, this means a set-and-forget servicing cadence. Once a refill is installed inside the dispenser, it works on its own with no fuss. There is no spray mechanism to jam and no batteries to run flat. Staff do not need to open the unit weekly to check contents or reset timers. This frees up time and resources for other priorities.

Passive systems also remove user dependency. The fragrance releases continuously through natural air currents, so the experience stays the same regardless of when someone walks in. Aerosol air fresheners can leave noticeable gaps between sprays. Passive air care eliminates that inconsistency and provides a steady, high-quality fragrance that helps every washroom, lobby, or office corridor smell clean.

Why Facilities Are Shifting to Passive Systems

The move toward passive air care is driven by practical considerations that affect daily operations, sustainability targets, and overall program management across multiple building types.

Consistency Across Washrooms and Shared Spaces

Passive air fresheners provide the same level of fragrance output around the clock. Whether it is early morning or late afternoon, the air in a washroom or break room remains fresh. This consistency matters a lot for hotels, restaurants, hospitals, and office buildings where customers expect shared areas to feel clean at all times.

Many passive air-care solutions also neutralise malodorous particles rather than simply masking them. That means the system helps eliminate bad odours at the source rather than masking them with a stronger fragrance.

Reduced Maintenance Touchpoints

Passive systems are designed for minimum servicing. Long-lasting refills can function for 60 to 90 days or more. That translates to fewer service visits and a predictable schedule. The benefits are clear for both facility managers and the end users of each space. Staff spend less time on air care maintenance and more time on other cleaning work.

Cleaner Program Management Across Multiple Sites

When a business operates across multiple locations, it is important to understand how standardising air care can reduce overhead. Passive systems make this easier because every dispenser runs the same way. There is no variation in spray timing, and there is no risk of dead batteries at one site while another has expired cans.

These systems also support sustainability targets. Battery-free, propellant-free products reduce environmental impact compared to aerosols, helping facilities meet zero-waste policies without adding complexity to procurement.

CirculAir 90™ as the Modern Passive Option

CirculAir 90™ from Rubbermaid Commercial Products is the latest generation of passive air care designed for commercial facilities. It combines battery-free operation, recyclable refills, and long-lasting fragrance output into one system that is easy to install and simple to run.

An ISO-compliant life cycle assessment conducted by South Pole found that the CirculAir 90™ refill produces 11% fewer greenhouse gas emissions and uses 36% fewer metal and mineral resources than the previous TCell™ refill. The study showed reduced impact across all 16 key environmental categories.

Battery-Free Operation

Both the CirculAir 90™ dispenser and refill are completely battery-free. The system uses a mechanical design that requires no electricity. This eliminates the need for battery servicing across every unit in a building. The dispenser operates silently, making it ideal for quiet areas such as libraries, patient care rooms, and office spaces.

Refills Designed to Be Recyclable

Each CirculAir 90™ refill is made from a single, commonly recyclable material. There is no disassembly required. Once a refill has been used, it goes straight into the recycling stream without any fuss. In Australia and New Zealand, recyclability has been assessed and verified through the APCO Packaging Recyclability Evaluation Portal (PREP), giving facility managers confidence that the product supports their sustainability claims.

90+ Days of Fragrance Output

Each refill delivers fragrance output lasting at least 90 days. Once you install a refill, you do not need to touch it again for three months. One dispenser and refill covers approximately 6,000 cubic feet of space, making each unit effective for mid-size washrooms with 3 to 4 stalls or fixtures.

Eight Fragrance Options to Suit Every Space

CirculAir 90™ offers eight fragrance options at varying intensities. Mild options like Pure and Polar Mist suit office lobbies and aged care common areas. Medium choices like Mango, Relaxing Spa, and Cucumber Melon work well in hotel rooms and waiting areas. For high-traffic washrooms where moisture and heavy use create persistent odours, intense fragrances like Blue Splash and Citrus provide the stronger air care needed. Blue Splash delivers a fresh, water-bright orange scent with white floral notes, while Citrus offers a sweet and juicy orange that reads as functionally clean.
