Mira Advance 100
Best OverallPros
- Very quiet operation at 26 dB
- High airflow for standard bathrooms
- Easy to install with included kit
Cons
- No timer or humidistat built in
- Plastic grille may feel less premium
The Mira Advance 100 is a standard extractor fan designed for bathrooms up to 9 square meters. It delivers 98 m3/h of airflow, which is sufficient for most UK bathrooms, and operates at a whisper-quiet 26 dB(A). Owner reviews on retailer sites highlight its simple installation and reliable performance over time.
Build quality is typical for Mira: a robust motor with a 3-year warranty. The fan is IPX4 rated, meaning it is splashproof. While it lacks extra features like a timer or humidity sensor, its core function is excellent, making it a top choice for straightforward ventilation needs.
Mira Economy 100
Best BudgetPros
- Very affordable price point
- Simple, reliable design
- Good for small bathrooms
Cons
- Louder than premium models
- Lower airflow rating
The Mira Economy 100 is the entry-level option for those on a tight budget. It provides 85 m3/h of airflow, which is adequate for small bathrooms or cloakrooms. Owner reviews note that it is noisier than the Advance range, but it gets the job done without fuss.
Build quality is basic but functional, with a 2-year warranty. It is IPX4 rated and comes with a standard backdraught shutter. For secondary bathrooms or rental properties, the Economy 100 offers good value for money, though you sacrifice some quietness and airflow.
Mira Advance 100 HT
Best with HumidistatPros
- Automatic humidity detection
- Still quiet at 28 dB
- Same high airflow as Advance 100
Cons
- Higher cost than standard model
- Sensor can be overly sensitive
The Mira Advance 100 HT adds a built-in humidistat to the popular Advance 100 platform. It automatically activates when humidity rises, which is ideal for bathrooms prone to condensation. Owner reviews praise its ability to keep mirrors clear and reduce mould, though some note the sensor can trigger from steam from a kettle in a nearby kitchen.
It retains the same 98 m3/h airflow and quiet operation, with a slight increase in noise to 28 dB(A). The 3-year warranty and IPX4 rating remain. This is a great choice for bathrooms that need proactive moisture control without manual intervention.
Mira Advance 100T
Best with TimerPros
- Adjustable run-on timer
- Same quiet performance
- Helps clear steam after shower
Cons
- Timer adds complexity to install
- No humidistat
The Mira Advance 100T includes an adjustable timer that keeps the fan running for a set period after the light is switched off. This is useful for clearing residual steam after a shower. Owner reviews appreciate the flexibility, with the timer adjustable from 5 to 20 minutes.
It shares the same core specs as the standard Advance 100: 98 m3/h airflow, 26 dB(A) noise, and a 3-year warranty. The timer function requires a separate live feed for the fan, which may complicate installation for some. It is a solid choice for those who want the fan to run on after leaving.
Mira Advance 100S
Best for Shower RoomsPros
- Higher IPX5 water resistance
- Quiet and powerful
- Good for direct shower areas
Cons
- More expensive than standard
- Limited availability
The Mira Advance 100S is designed for shower rooms where water exposure is higher. It features an IPX5 rating, meaning it can withstand water jets, making it safer for installation directly above a shower. Owner reviews note its robust build and consistent performance in wet environments.
It offers the same 98 m3/h airflow and 26 dB(A) noise level as the standard Advance 100. The 3-year warranty applies. The higher IP rating adds cost, but for shower rooms or steam-heavy bathrooms, it provides extra peace of mind against moisture damage.
What to check before buying a Mira bathroom extractor fan
First, measure your bathroom size. A fan with at least 85 m3/h is suitable for rooms up to 9 square meters. Larger rooms may need higher airflow. Check the noise rating: 26 dB is very quiet, while 32 dB is noticeable. Also consider the IP rating: IPX4 is standard for bathrooms, but IPX5 is better for wet zones.
Mistakes to avoid
Do not buy a fan without considering your wiring setup. Timer and humidistat models often require a separate live feed, which may need a professional electrician. Avoid choosing a fan based solely on price, as a noisy unit can be annoying. Finally, ensure the fan is the correct size for your ducting, typically 100mm for most UK homes.
