AIR 6 Cloud-100HT bathroom extractor fan with adjustable humidity sensor & timer (100mm ducting, IP45)
Product description
The essentials
If your bathroom ventilation feels a bit hit-and-miss, a humidity-sensing extractor fan can make daily life easier. The AIR 6 Cloud-100HT is a wall or ceiling-mounted bathroom extractor fan designed to pull moisture out based on humidity levels, then keep running for a set overrun using a timer.
It’s aimed at straightforward, everyday bathroom and shower room ventilation where you want more than a basic on/off fan. That said, it’s not a smart home unit and it’s not about “maximum performance at all costs” — it’s about controlled extraction that’s practical to live with.
What it’s for (and what it helps with)
On paper, this fan is built around two control inputs: an adjustable humidity sensor and a timer. The humidity range is adjustable from 50% to 90% RH, and the timer can run for 1 to 30 minutes. In use, that typically means you don’t have to manually guess how long to ventilate after a shower.
A concrete example: you take a shower, the humidity rises, and once it crosses your set threshold the extractor should switch on. After you’re done, the timer helps it continue for a short period so moisture doesn’t linger.
Key takeaways for everyday use
Where this model feels particularly sensible is the combination of silence and control. The fan is rated at 30dB(A) at 3m, which is relatively gentle for a bathroom extractor. For many households, that’s the kind of noise level that won’t dominate the room, especially if you’re ventilating in the evening or overnight.
Power-wise, it’s specified to deliver 26.5l/s (95m3/hour). That extraction rate is the sort of figure you’d look for if you want solid performance rather than a token fan.
There are also design details that matter more than you’d think: it includes a thin plastic anti-backdraft shutter and an anti-vibration silicone damper. Together, these are the small touches that can help reduce unwanted draughts and noise transmission.
Worth noting: real-world airflow performance can depend quite a lot on how your ducting is installed (runs, bends, and whether the duct is sized and sealed properly). So the headline extraction rate is helpful, but installation details still count.
Installation and suitability in UK bathrooms
This unit is intended for 100mm / 4" ducting, which covers many standard bathroom ventilation setups. It’s rated IP45, suggesting it’s designed to handle bathroom moisture and splash-prone areas.
The description also states it’s for Bathroom and Shower Room ZONE 1. If you’re planning to fit it yourself or commissioning it, it’s important to follow the relevant electrical and bathroom zone rules — and to confirm the zone classification matches your specific layout.
The box includes setup aids like coloured stripes, wall plugs, and screws, so you’re not starting from zero with basic fixing materials.
What stands out (and where it may fall short)
What stands out is the “set-and-forget” approach: adjustable humidity control plus a timer, aiming to manage indoor air quality without you constantly thinking about it. The anti-backdraft shutter and the vibration damper are also a good sign if you’ve ever been annoyed by fans that rattle.
Still, it may not suit everyone. If your bathroom is already very easy to ventilate (for example, you rarely get heavy condensation and your current setup is doing the job), you might feel the extra control isn’t essential. Also, if you prefer the simplest possible fan with no humidity automation, this could be more features than you need.

Buying verdict
Is it worth it?
Buy it if you want a bathroom extractor fan that reacts to real conditions (humidity) and lets you control the run-on period with a timer. It suits people who often get condensation, want quieter extraction for day-to-day use, and have a ventilation setup already planned for 100mm / 4" ducting.
Skip it (or at least double-check suitability) if you only need a very basic extractor, if your installation details don’t match the 100mm duct requirement, or if you’re not comfortable confirming the bathroom zone and compliance requirements for an IP45 fan intended for ZONE 1.
The AIR 6 Cloud-100HT is more of a “properly thought-out” bathroom fan than a minimal budget extractor — and that’s usually where it earns its place.
Mini FAQ
How does the adjustable humidity sensor work?
You set a target humidity level (50% to 90% RH). The fan should respond when conditions cross that threshold, helping extraction happen when it’s actually needed.
Can I control how long it runs after switching off?
Yes. The timer is adjustable from 1 to 30 minutes, which helps manage the moisture left after showering.
Is the fan suitable for bathrooms?
It’s rated IP45 and the description states it’s intended for bathroom and shower room ZONE 1. Confirm your bathroom layout matches the relevant zone requirements.
What duct size does it need?
It’s specified for 100mm / 4" ducting, so it’s best when your existing route or planned installation uses that size.
Will it be noisy?
It’s rated at 30dB(A) @ 3m, which suggests quiet operation for typical bathroom use. Exact perceived noise can still vary with installation and duct routing.
