Mira Sense
Best OverallPros
- Very quiet operation
- Automatic humidity sensing
- Sleek, low-profile design
Cons
- Higher price than basic models
- Requires professional wiring
The Mira Sense is the standout performer in the range. It delivers 15 L/s of airflow at just 24 dB, making it one of the quietest extractor fans available. The built-in humidistat automatically activates the fan when moisture levels rise, which is ideal for preventing mould and condensation without manual intervention.
Owner reviews consistently praise its build quality and reliability. The low-profile white grille fits flush with the ceiling or wall, blending into most bathroom decors. It meets UK Building Regulations Part F for ventilation, making it a safe choice for new builds and renovations.
Mira Ecostream
Best Budget / Energy SavingPros
- Very energy efficient (low wattage)
- Affordable price point
- Easy to install
Cons
- No automatic humidity sensor
- Slightly louder than Sense
The Mira Ecostream is designed for energy-conscious buyers. It uses a DC motor that consumes very little power while still moving 13 L/s of air. This makes it a great choice for bathrooms that need continuous trickle ventilation without high running costs.
It operates at 28 dB, which is still quiet enough for most bathrooms. The simple pullcord control is reliable, though it lacks the automatic sensing of the higher-end models. Owner reviews note that it is a solid, no-frills fan that does its job well.
Mira Aura
Best for High Humidity / Large RoomsPros
- Highest airflow in the range
- Built-in timer and humidistat
- Stylish, modern design
Cons
- Louder than Sense at high speed
- Larger unit may not fit all spaces
The Mira Aura is built for larger bathrooms or rooms with high moisture levels, such as those with a shower. It moves 18 L/s of air, which is the highest in the Mira lineup. The combination of a humidistat and an adjustable timer means it can run on after you leave to clear steam effectively.
At 30 dB, it is not the quietest fan, but it is still acceptable for most settings. The design is modern with a glossy finish. Owner reviews highlight its effectiveness at clearing condensation quickly, making it a favourite for family bathrooms.
Mira Plug-in
Best for Easy DIY InstallPros
- No hardwiring required (plug-in)
- Very simple installation
- Good for small bathrooms
Cons
- Lower airflow capacity
- Noisier than other Mira fans
The Mira Plug-in is designed for DIYers who want to avoid calling an electrician. It comes with a pre-wired plug, so you just need to mount it and plug it into a nearby socket. This makes it ideal for small en-suites or cloakrooms.
It moves 10 L/s of air, which is sufficient for small spaces but not for large bathrooms. The noise level is 32 dB, which is noticeable but not intrusive. Owner reviews appreciate the convenience, though some note it is less powerful than hardwired models.
Mira Smart
Best for Smart Home IntegrationPros
- App control and scheduling
- Quiet operation
- Integrates with smart home systems
Cons
- Requires Wi-Fi setup
- Higher price point
The Mira Smart is the most technologically advanced model. It offers app-based control via your smartphone, allowing you to set schedules, adjust fan speed, and monitor humidity levels remotely. It also works with voice assistants for hands-free control.
It delivers 15 L/s at 26 dB, making it both effective and quiet. The setup is straightforward, though it does require a stable Wi-Fi connection. Owner reviews like the convenience of automation, especially for rental properties or holiday homes.
Who is a Mira bathroom extractor fan for?
Mira extractor fans are designed for UK homeowners and landlords who need reliable, Part F compliant ventilation. They are a good fit for anyone who values quiet operation, energy efficiency, and a trusted brand. The range covers options from basic manual fans to smart, app-controlled models.
Performance and build quality
Mira fans use high-quality DC motors that are both efficient and durable. The airflow ratings range from 10 L/s for small rooms to 18 L/s for larger spaces. Noise levels are consistently low, with the Sense model being one of the quietest on the market at just 24 dB.
Build quality is solid across the range. The grilles are made from UV-stabilised plastic that resists yellowing over time. The back-draft shutters are effective at preventing cold air from coming back into the room when the fan is off.
Alternatives to Mira
If you are considering other brands, Manrose offers a wide range of budget-friendly fans, while Vent-Axia is known for high-performance commercial-grade units. EnviroVent also has a strong reputation for quiet, efficient fans with good warranties.
What to check before buying a bathroom extractor fan
First, measure your bathroom size. UK Building Regulations require a minimum airflow of 15 L/s for rooms with a bath or shower. Second, check the ducting route. Fans can be wall-mounted or ceiling-mounted, and the duct length affects performance.
Third, decide on control type. Pullcord is simple and reliable, while humidistat models automate operation. Fourth, consider noise levels. Fans under 30 dB are generally considered quiet. Finally, check the IP rating. A fan in a zone near water needs at least IPX4 protection.
Mistakes to avoid when installing an extractor fan
One common mistake is undersizing the fan. A fan that is too weak will not clear steam effectively, leading to mould. Another is poor ducting. Using flexible ducting with sharp bends reduces airflow significantly.
Also, avoid placing the fan too far from the shower. It should be close enough to capture steam but not directly in the spray zone. Finally, do not skip the back-draft shutter. Without it, cold air will enter the room when the fan is off.
