<![CDATA[ <article> <p>It seemed like it might never happen, but the weather is finally starting to turn cooler — and if you're anything like me, you'll soon be reaching for your thickest socks and jumpers. I won't go as far as turning the heating on though, because <a href="https://www.amazon.co.uk/BLUEAIR-ComfortPure-Powerful-Smart-Purifier/dp/B08KTFV2XQ/ref=sr_1_1">the Blueair ComfortPure 3-in-1 air purifier and heater is now just £237</a> (was £399) in the <a href="http://techradar.com/tag/prime-day">Amazon Prime Day</a> sale.</p><p>I'm a naturally chilly person (I keep a heated pad under my desk year-round) and I've been on the lookout for a compact fan heater to keep myself snug when working from home, and this Blueair model is perfect. Not only does it warm a small- to medium-sized room in the colder months, it also serves as a cooling fan during summer heatwaves, and filters dirt and allergens out of the air all year round.</p><p>• <a href="https://www.amazon.co.uk/primebigdealdays">Browse the full Amazon Prime Day sale</a></p><p>This three-in-one device got the seal of approval <a href="https://www.techradar.com/home/air-quality/blueair-t10-review">from our reviewer Becca Caddy,</a> so I know it'll be a reliable buy. "One feature I particularly liked was the way the purifier automatically ramped up when air quality dropped and then settled back down once conditions improved," she said. "It meant the unit never felt like it needed to run at full power all the time." </p><p>That's great news considering the cost of fuel, and combined with this huge Prime Day discount, makes it a great value alternative to cranking up the central heating.</p><h2 id="today-39-s-best-blueair-deals">Today's best Blueair deals</h2><div class="product"><a data-dimension112="ec273d6a-c0ae-11f1-a9ed-cde8f75843e2" data-action="Deal Block" data-label="ComfortPure 3-in-1 T10i Air Purifier" data-dimension48="ComfortPure 3-in-1 T10i Air Purifier" data-dimension25="£237" href="https://www.amazon.co.uk/BLUEAIR-ComfortPure-Powerful-Smart-Purifier/dp/B08KTFV2XQ" target="_blank" rel="nofollow"><figure class="van-image-figure " ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:1221px;"><p class="vanilla-image-block" style="padding-top:115.64%;"><img id="Bmt97B3ejqL98auBvvNWBP" name="ComfortPure 3-in-1 T10i Air Purifier" caption="" alt="" src="https://cdn.mos.cms.futurecdn.net/Bmt97B3ejqL98auBvvNWBP-1920-80.png" mos="" align="middle" fullscreen="" width="1221" height="1412" attribution="" endorsement="" credit="" class=""></p></div></div></figure></a><p><strong><a href="https://www.amazon.co.uk/BLUEAIR-ComfortPure-Powerful-Smart-Purifier/dp/B08KTFV2XQ" target="_blank" rel="nofollow" data-dimension112="ec273d6a-c0ae-11f1-a9ed-cde8f75843e2" data-action="Deal Block" data-label="ComfortPure 3-in-1 T10i Air Purifier" data-dimension48="ComfortPure 3-in-1 T10i Air Purifier" data-dimension25="£237">ComfortPure 3-in-1 T10i Air Purifier: was £399 now £237</a></strong><br>A heater isn't just for winter — not when it's also an air purifier to tackle allergens, and a cooling fan to keep you comfortable during heatwaves.

Its off-white colour and minimal styling mean it feels premium without trying too hard. We also appreciate its anti-tip sensor, which switches the unit off automatically if it's knocked over. </p><p>The mobile app is excellent too, letting you adjust the Blueair's settings, set schedules, and even set it to activate based on your location. Want your room to start heating or cooling so it's comfortable when you arrive home?

It also has a top-mounted control panel and remote control. Alternatively, you can link it to Amazon Alexa and control it from an Amazon Echo speaker via voice commands.</p><p>For us, the only real drawback was the price, but with this pre-Prime Day deal, that's no longer an issue.</p><div data-widget-type="review" data-model-name="Amazon Prime"></div> </article> ]]>
