SmartAir BOOST 3pk - Portable Radiator Fan - Cordless, Rechargeable & Automatic – Intelligent Sensor - Improve Heat Distribution & Circulation - Compact Heat Booster - Reduce Energy Wastage

I was very skeptical of this product. Our living room has a large bay window and it struggles to heat up/heat evenly and always the coldest room in the house. We were using a fan heater to "top" the heat in the room up but was costing a fair sum. We bought this radiator fan and it works well, our living room will now sit at 21-22 degrees instead of 18-19 while the heating is on. It work well, mildly blowing 30-40 degree air through the middle of the room, the room heats quicker then stays at a higher temperature but costs a faction of the cost to run 20w vs 2000w of a fan heater. Some people with sensitive hearing may not like it, it's not too loud but it is there. You won't hear it over a tv though. The price for these sort of items is probably higher than it should be but it's worth the price. We're planning to try using it on a radiator next to where we dry our clothes in tandem with a dehumidifer to see how that works also. It can be moved very easily and doesn't have to be moved. i haven't even put the securing nuts as it just sits on the radiator properly anyway. It automatically comes on when your radiator is hot so no user input is needed!

Exactly what I wanted thanks

It worked

Does what it says

The idea is great and they work well. Just a shame one stopped charging after a few months and the other sparked and popped when I went to charge it.I'd they can do something abt the issues that seems to be common with these then I'd be up for buying again.Had to contact amazon and they let me return for a refund.

I read over several months re this and other fans. Saw the review re cold air circulating etc. I decided I was fed up of hitting a heat wall every time I stood up whilst being a little chilly below so decided I would try these.My room is quite large, I put them on a large ceramic heater… brilliant result, my whole room is now getting heat…wall to wall, floor to ceiling.A slight negative for me is the fans seem to turn off soon possibly as the heat is too much but even though I dropped the thermostat down it still occurs but I find by setting the on and off via the Alexa app I just audibly turn the heater off and as it cools the fans kick in circulating the heat well again. Note, I’ve dropped the thermostat down!I did initially notice the ‘cool air’ being blown about but either I’m used to it or it’s eased and I find the fans are very effective in sorting my heat issue.

We bought the larger of the SmartAir. Was a bit dubious as to wether this would work or not but needn't have worried. It works really well. We have an 18 foot room with 2 large radiators, but the room never seemed to get really warm. This smart air has changed the temperature in the room form 18/19 degrees to 22/23 degrees. The smart air pushes warm air from the radiator evenly over the room, leaving no colder spots. We found it works best when sending the air the length of the room instead of across it. The only downside would be the lenght of the charger lead. You do need a socket within a few feet of the unit. All in all we are very please with it and would highly recommend

Limited run time 😔 tho works well when it does.
