## Description

Product Description Kair Smart 100mm Filterless Extractor Fan with Humidistat Timer and Data Logger Compact and aesthetically pleasing, this continuously running extractor fan has inbuilt energy and noise reduction technologies to limit cost and noise disturbance, all whilst continuously removing stale, moist old air from the property. A humidity sensor intelligently reacts to a sudden increase in air moisture levels, temporarily boosting the fan to extract at a faster rate. This reduces the humidity levels in your home, and prevents condensation and mould formation. The unit is filterless as an extractor fan has no need to filter air being taken out of the property. As a result, this fan has the advantage of requiring no filter replacements, so there is less maintenance and the unit again saves you money, time and hassle. The Kair Smart extractor fan has been created for the convenience of both homeowners and landlords alike. A busy household and an apartment full of tenants can function in much the same way, people cooking and showering at different times of the day creates a lot of condensation. This powerful but quiet extractor fan will effortlessly handle even the busiest of properties. What can it do? The Kair Smart extractor fan intelligently reacts to a sudden increase in moisture, and enables its “boost” function to extract at a much higher rate until the sensors detect the moisture levels have decreased a sufficient amount. This alleviates any concern over high humidity levels within the property, creating a far more pleasant living environment for families and tenants. Should you feel that the humidity level in your property is too high, or you wish to clear out scents from the cooker or bathroom, you have the option of a pullcord or remote switch (depending on the install option you chose), giving you complete control and comfort. You also have the ability to set the timer function for the fan, allowing you to decide how long the fan stays in “boost” mode for, after a shower for example. This can be connected to the light switch to enable the fan to run whilst someone is using the bathroom, and for a predetermined length of time after the light switch is turned off. Quiet and aesthetically pleasing. Humidistat, Timer & Data Logger. Daily run monitor - Records overall usage time of fan. Ceiling, window or wall mounting available with additional components. Cost effective due to low installation and maintenance costs, and energy saving technology. Help prevent damp and mould growth You can rest assured that this extractor fan has been tested under the strictest scenarios and is powerful and reliable enough to deal with even the busiest homes. The Kair Smart Fan Smart sensors continuously monitor the environment, only boosting the fans extraction when necessary, reducing energy costs and eliminating condensation as soon as it develops! The Smart fan has been specifically designed to cope with each type of environment it is placed into. The very low running costs and minimal maintenance make this the ideal fan for any busy property, or people looking for a simple, effective condensation solution that requires little to no monitoring. Suitable for any room! Bathroom / Toilet Extraction Fan The fan will automatically reduce the humidity levels in your bathroom or toilet and clear out unpleasant smells. Set a longer Timer or use the Boost Function to extract at a much higher rate when needed. Aesthetically pleasing design will seamlessly blend into the décor of your bathroom. Living Room Extract Fan Special consideration has been paid to reduce the noise levels of the Kair Smart fan, with 33dB being it’s maximum whilst on boost mode. This is comparative to the ambient noise of a library! Trickle Mode setting will not interfere when watching your favourite movie or TV show! Kitchen Extraction Fan There is an abundance of warm and moist air while cooking, this creates the perfect situation for mould to develop. The smells coming from the cooker that might be disagreeable to some of your family members.

Window Mounted A window kit (available separately) makes for a simple a speedy installation through any window in your property, allowing the option to still have an extractor fan when cutting through walls is not an option. Ceiling Mounted For ceiling or wall mounting, a 100mm (4inch) hole is either cut through the wall to the exterior of your property, or through the ceiling into the loft cavity. Wall Mounted The fan can then be ducted straight through to the exterior or loft cavity with a simple external grille for more pleasing aesthetics. Why Choose the Kair Smart Fan? Very few extractor fans on the market can be described as “Smart”. The Kair Smart fan differs, it intelligently reacts to its environment, working almost autonomously because of its multiple sensors and the advanced technology associated with them. Common activities increase the amount of moisture within a home, from washing machines, cooking or having a shower or bath. It can also vary at any point through the day within a busy home or social housing situation due to peoples differing schedules and hygiene habits. This creates the perfect situation for mould to develop, as there is an abundance of warm and moist air in the property. There are also smells coming from the cooker that might be disagreeable to some of your family members or tenants. Ceiling, window or wall mounted extractor fan to suit any installation type (window kits available). Timers reduce night time activity - Prevents night time noise and saves energy Humidistat measures moisture, only boosting the fan when required, saving energy Quiet and aesthetically pleasing

Review: Good value for the features included - For a unit with humidity control this is reasonably priced. It also has a lot of features / settings that can be adjusted fairly easily from the menu. This is handy for adjusting the speed / timer / humidity target level. I wanted the flex outlet at the bottom as can be seen in my pictures so. Had to move the little magnet to the opposite corner to get the kair logo the right way up and not trigger the unit’s safety feature, was fairly easy to do although you then have to adjust settings with the display upside down which wasn't too bad and once done your unlikely to need to adjust much again. Happy with this unit so far and would recommend/ use again. Instructions were good and overall I'm happy with the quality. Comes with a pull cord but this can be taped up and put inside but ensure the boost light is out before you put cover on otherwise you will need to go back in to pull the switch , mine came with the switch set to on.
Review: Replacement working - Replaced an older extractor fan with this fan, and the original fan ordered stopped working, with or without the cover on. However, it was otherwise what I needed, and it didn't seem like other people had the same problem, so I ordered a replacement. The fan is very effective at keeping humidity down. I notice that my bathroom mirror doesn't steam up during my short showers. It is also fairly quiet in its constant mode, but definitely not silent... See video attached. The high speed mode - activated by switch - has a roll-over timer, but that only works if you turn it on for more than 3 minutes. Apparently my showers are too short! There is also the humidity sensor, so it definitely takes care of any humidity from showers, but if you go to the loo then just remember to turn the switch on first.

### ⭐⭐⭐⭐⭐ Perfect for en-suites
*by O***J on 27 November 2021*

If you have an en-suite or a bathroom close to a bedroom then you’ve probably had the desire to either make the extractor fan quieter or shorten how long it runs for after the light is turned off due to noise. Unfortunately if you shorten the timer too much or turn down the fan speed you end up with damp problems. This fan works really well, since the humistat, which works well, allows you to have a high (and therefore noisy) fan speed after a shower or bath and it will run until the bathroom is back to your houses “normal humidity”. However you can have a lower fan speed (and hence noise level) for when the light switch is on. This is perfect as the fan can be setup such that it’s only audible outside of the bathroom after you’ve taken a shower bath. The “run on” timer is also adjustable, so you can have the fan switch off straight away when you leave the bathroom, perfect for middle of the night use to minimise disturbing sleeping. Practicalities Making adjustments to the settings is easy as the face plate is magnetic. I had to adjust the humistat trigger level down as the normal moisture level of my house was triggering it. I made my life difficult by playing with the pull cord before installing since the pull cord was left in “on” position so the fan was just running at full chat no matter the circumstances or settings. I had hidden the pullcord in the unit, so I had to take it apart again to put the pull cord in to “off” and then rehide the pull cord in the unit. When you connect the power, either from fuse box or isolator switch the light switch for the bathroom needs to be in “on” position. Otherwise it will run continuously when the switch is off and turn off when you turn the switch on. The only annoying thing is that the humistat won’t trigger until the light is off. So if you take a shower with the light on, it will run at the normal speed and then will only switch to the level you’ve chosen for the humistat when the light goes off. This is a bit annoying as I had the normal speed as pretty low to be quiet and then a fast speed when things got wet and I had to adjust the normal speed up as it was getting too steamy while showering.
