Vent-Axia Svara 409802 4W Lo-carbon App Controlled Extraction Fan is rated 4.5 out of 5 by 13.
Rated 5 out of 5 by from Expensive but very good A previous person wrote that it lost its settings when powered down, well I didn’t have that issue. I took it down to redecorate the ceiling and it remembered it’s settings. It was a bit more than I wanted to pay, but the humidistat feature is great. It comes on and off by itself, and I don’t notice the constant on feature. I did turn off the twice daily purge feature, as that wasn’t needed for my en suite. It looks good, easy to clean, only used the app once. Would have preferred it cheaper but it’s been a good buy

Rated 5 out of 5 by from Fanfare for the Common Fan I had to fill holes, drill new ones and redecorate where the old, rectangular fan was, but it has been well worth it. It looks stylish, is almost silent in operation and most importantly, it does the job superbly. I have it on humidistat operation and it detects moisture in the bathroom perfectly. The fan then increases in strength if it needs to and clears the bathroom of steam really quickly. It's also only 4 watts so is really economical. Setting it up and controlling it from a mobile phone app is innovative and very clever. The only thing I can't yet judge is its reliability but with a five year guarantee, I can't see much heartache in that direction.

Rated 5 out of 5 by from Great fan with useful app This fan is simple and effective with no need for extra switching or linking to the light switch. The humidity sensor works perfectly and the fan runs till humidity is back to normal. The light sensor is clever - you can set the light sensor so the fan only activates if the light has been on for a chosen time, save it coming on every time the light is flicked on. You can also set how long the fan runs for once it does activate. You can chose the fan speed for light activation and humidity separately..I have the humidity on its lowest setting to minimise noise and it handles multiple showers with ease as long as a window is slightly open (cold, non insulated walls and teenage daughters). Noise seems fine, quieter than others I've heard. The app control is great. You can press boost to put it on max for 15mins and also set a quiet time where so won't activate during the night. Feels well made and looks classy; easy to fit, 3 screws & 2 cables (no earth)...ours is in the ceiling, the outlet pipe on the back is shallow, proper connections might be available but a 100mm duct pipe connector fits nicely into the back of the fan to extend the outlet. One review mentions the pin and pairing problems..might be out of date..if you need the pin you just pull the middle of the fan out and it's printed on it, easy. Apps been perfect so far on a Samsung s7. Overall: costs a bit more than basic fans but the app, features, performance and quality make it worth it in my opinion.

Rated 5 out of 5 by from Good at shifting air Works perfectly. Ran off an LED driver with no problems. App works fine too on iPhone X. I disabled the light sensor as wanted it to work purely on humidistat. May purchase another for the other bathroom.

Rated 5 out of 5 by from Super Quiet Extractor Fan Our last fan was really noisy and next to the bedroom, this one is really quiet. The builder installed it but didn't look complicated but it would be useful if they had the app code on the box as well. I haven't yet used the app because I didn't scan the code on the product before it was installed. Maybe there is another way but not had a chance to find it. All in all, effective and quiet.

Rated 5 out of 5 by from Replaced a noisy fan Replaced my noisy bathroom fan with this stylish bit kit. I will definitely be fitting it on future jobs and would recommend it to others.

Rated 3 out of 5 by from Fan Brought this fan after trying two other models one Vent-Axia one expelair. I was really hopeful this model would be the one to solve my extraction problems I have had with previous models. In short it is a good looking fan and is fairly quiet, but the app is not ready for use. It does not load properly if you answer the questions correctly. I contacted Vent-Axia and they said you need to answer no to all the questions even though some of them need a yes answer. It would not adjust to the setting I gave it and I am about to change it for another one as Vent-Axia say it sounds like it is faulty after speaking to them.

Rated 2 out of 5 by from ok but not as good as it could The good: it's really quiet, and you can control it via bluetooth. The bad: you need a special unique code printed in the manual it comes with to pair with the fan, so if you lose this you're stuffed. The app doesn't currently work with every version of Android, will they keep maintaining it? I'm worried, I couldn't use it with my (admittedly quite old) phone, had to use partners. The control you get with the app is only ok, you can't really set a schedule or anything in the way you might expect. Also if you have a power cut it forgets any settings and you have to set it up again. On balance I regret buying it.
