Triton T4-MST
Best OverallPros
- Very quiet operation
- High airflow for size
- Easy retro-fit installation
Cons
- No built-in timer
- Higher price than basic models
The Triton T4-MST is the quietest and most powerful standard fan in the Triton range. With a 100 m3/h airflow and only 22 dB noise output, it clears steam quickly without disturbing bathroom use. The IPX4 rating makes it safe for Zone 2 installation, and the retro-fit design fits standard 4-inch ducting.
Owner reviews consistently praise its near-silent operation and effective moisture removal. The lack of a timer means it runs only when the light switch is on, but for most medium bathrooms this is sufficient. It is the best choice for anyone prioritising low noise and high performance.
Triton T4-S
Best BudgetPros
- Very affordable price
- Reliable basic performance
- Simple installation
Cons
- No timer or humidity sensor
- Noticeable fan noise
The Triton T4-S is the entry-level model that still delivers solid ventilation for small bathrooms. With 85 m3/h airflow and 28 dB noise, it is louder than the T4-MST but perfectly adequate for a cloakroom or en-suite. It is a straightforward on/off fan controlled by the light switch.
User reviews note it is good value for money and easy to install, but some wish for a timer to run after lights off. If you need a simple, cheap extractor fan without extra features, the T4-S is a reliable choice that gets the job done.
Triton T4-T
Best with TimerPros
- Adjustable run-on timer
- Good airflow for medium rooms
- Quiet operation
Cons
- Timer requires neutral wire
- Slightly pricier than T4-S
The Triton T4-T adds a useful adjustable timer that keeps the fan running for 1 to 20 minutes after the light is switched off. This is ideal for clearing lingering moisture after a shower. With 95 m3/h airflow and 26 dB noise, it balances performance and quietness well.
Owner feedback highlights the timer as a key feature for preventing mould, though installation is slightly more complex if your wiring lacks a neutral. For bathrooms that need post-shower ventilation, the T4-T is a smart upgrade over basic models.
Triton T4-H
Best Humidity SensorPros
- Automatic humidity detection
- No need for manual switch
- Good for damp bathrooms
Cons
- Sensor can be sensitive to steam
- Higher cost than timer model
The Triton T4-H uses a built-in humidity sensor to automatically activate when moisture levels rise. This is perfect for bathrooms where you want hands-free operation. It delivers 90 m3/h airflow at 27 dB, which is effective for most standard bathrooms.
User reviews appreciate the auto-start feature but note the sensor may trigger from steam from a shower before you enter. It is a convenient choice for families or anyone who forgets to switch on the fan manually.
Triton T4-MST
Best QuietPros
- Extremely quiet at 22 dB
- Highest airflow in range
- Simple retro-fit design
Cons
- No timer or sensor
- Premium price
The Triton T4-MST appears again as the quietest option, with the same 22 dB noise level that is barely audible. It moves 100 m3/h of air, making it the most efficient standard fan for clearing steam quickly. The retro-fit kit means it can replace older fans without new ducting.
Reviews consistently rate it as the best for noise-sensitive users, such as in bedrooms or nurseries. If you want the quietest possible fan and don't need extra features like a timer, the T4-MST is the clear winner.
What to check before buying a Triton bathroom extractor fan
First, measure your room size. A small cloakroom needs at least 50 m3/h airflow, while a medium bathroom requires 85-100 m3/h. The Triton T4 range covers these needs well. Next, consider noise levels. Fans over 30 dB can be distracting, so aim for 25 dB or lower for quiet spaces. Finally, check your electrical setup. Timer and humidity models need a neutral wire, while basic on/off fans are simpler to install.
Mistakes to avoid when choosing an extractor fan
Do not buy a fan with insufficient airflow for your room size. An undersized fan will not clear steam, leading to mould. Avoid ignoring the IP rating. For Zone 2 bathrooms, an IPX4 rating is essential for safety. Also, do not skip a timer if your bathroom has no window. A run-on timer helps remove moisture after you leave, preventing damp issues.
How Triton fans compare to other brands
Triton competes with brands like Manrose and Vent-Axia. Triton fans are known for their quiet operation and reliable build, often at a lower price point than premium brands. The T4-MST's 22 dB noise level is among the quietest in the market. While Manrose offers more budget options, Triton provides a better balance of performance and noise for UK bathrooms.
