Product Information

IN terms of power consumption, having been on for four hours on the Everyday setting, the air purifier used only 0.008kWh of electricity, which is so low you’ll barely notice a change in your electricity bill. In the UK, this is less than 2p per 24 hours of continual use at this setting (based on an electricity price of 35p per kWh). In the US, the cost would be less than 1 cent for a 24-hour period (based on an electricity price of 20c per kWh). Note that prices vary between states and suppliers, so you may need to do your own calculations. Either way, the Blue Pure 411 Auto air purifier isn't an appliance that guzzles energy.

Dust, and pollens, are some of the larger airborne particles present, so most air purifiers will be able to capture and filter these out from the air. Do air purifiers cool the air? Capacity: small to medium rooms between 100 sq. ft. and 175 sq. ft. (AHAM rated at 161 sq. ft) / 120 cubic ft/min Clean Air Delivery Rate (CADR) The Shark 3-in-1 Air Purifier, Heater and Fan is a great alternative to the Dyson Purifier Hot+Cool Formaldehyde HP09, coming in at a fraction of the price. In addition, there's no accompanying app, which may just suit those looking for a more simple unit. For bedrooms, hallways, front rooms, parlours and anywhere else you're not setting fire to stuff the Blue Pure 411 seems to do a perfectly good job. The maximum room size recommended by Blueair is 15 m sq which, understandably, is on the small size. We haven’t used the air filter in our kitchen, which is at the other end of the house, so I can’t say how this does for cooking odors. Other reviewers suggest the Blueair works really well though, as long as you move it to the kitchen while cooking. Similarly, it’s hard to tell how effective the Blueair is for VOCs, given that we’re pretty diligent about avoiding these in our home.Blue Pure 411 cleans your indoor air completely five times per hour, and gives you great value from day one – and throughout your whole ownership. On normal operating speed, Blue Pure 411 uses only 1,5 watts, that's a big win for you and for the environment. In fact, as an Energy Star-Certified air purifier, Blue Pure 411 uses only half the energy of a small LED light! On the standard Everyday setting, the Blue Pure 411 Auto is quiet, measuring just 35dB on the sound meter. In Night mode, its gentle hum is barely noticeable, registering 29dB; chances are, your own breathing will be louder. As expected, the unit is louder in Boost mode at 55dB, but still no noisier than most fans I’ve encountered. part filtration system: captures 99% of common airborne PM 2.5 pollutants (allergens, odors, smoke, mold spores, dust mites, pet dander The Blueair Blue Pure has a 3-stage filtration process that first captures larger particles like dust and pet hair in an external washable pre-filter. The air then moves through a particle filter and activated carbon filter. With arguably better than HEPA technology, this air purifier traps airborne contaminants down to the size of a virus. The Blueair Blue Pure is great for clearing air of:

It's compact and very light at just 1.5kg so it's easy to carry the thing around. Putting it in the kids' rooms seems like an obvious use for the Blue Pure 411 but I do worry it might not survive the encounter in the long term, unless your children are particularly well behaved, or you put it out of their reach.What I love about the Blue Pure 411 is that there are no app data read-outs to fuss over or make you feel (more) paranoid about your air quality. It just unobtrusively clears the air 5 times per hour.

But, of course, how well the air in a room is purified – or the room temperature adjusted – will depend on the size of the room. For example, the LG PuriCare AeroTower Air Purifying Fan with True HEPA and UVnano LED can purify a room size of up to 818sq ft, whereas the Blueair Blue Pure 411 Auto is suitable for a room size of up to 441sq ft. Opt for an air purifier that isn't suitable for use in your room will mean that it ultimately won't be able to deliver optimum performance. Unless the air purifier has been specifically designed to purify and cool the air – the Dyson Purifier Cool Autoreact, for example – the model will not cool the air. Before T3, Duncan was a music and film reviewer, worked for a magazine about gambling that employed a surprisingly large number of convicted criminals, and then a magazine called Bizarre that was essentially like a cross between Reddit and DeviantArt, before the invention of the internet. There was also a lengthy period where he essentially wrote all of T3 magazine every month for about 3 years.AHAM certified room size is the size of room in which the air purifier can provide a full five air changes per hour. Therefore refreshing all of the air in the room through its filters once every twelve minutes.This is more relevant than 'maximum' room size which does not reflect an air purifiers genuine effective capability. Always be sure to only use the 'AHAM certified' room size for true comparison purposes. Because our filter is crib-side and is audible outside the room (on the top setting), I tested the decibel levels. From a meter away it was just 38 on high and 15 on low. This was lower than Blueair’s measurements of 46 decibels on high (the sound of a library) and 17 on low. Put simply, there’s no need to worry about using this filter beside a crib. CADR stands for Clean Air Delivery Rate and is an actual measurement of the amount of filtered air provided by the machine.This is the only true way to compare like for like between air purifiers when assessing how powerful they are. CADR is not the same as air volume which will always appear higher due to the fact that it is only a measurement of the units fan power (with no filter Installed). This relatively small air purifier is ideal for small bedrooms, offices, dorm rooms, and nurseries. My experience with the Blueair Blue Pure 411 Air Purifier Carbon filters remove chemical fumes including VOC's, traffic combustion gases, pet odours, tobacco smoke and many more gaseous pollutants.However not all carbon filters are the same. Basic carbon 'sheet' filters are generally lightweight and have little capacity to adsorb these pollutants effectively. On the other hand filters containing actual carbon 'granules' are infinitely more effective and should always be chosen over carbon sheets where the most effective gaseous pollutant removal is required.

Super easy one-button control makes it easy to turn your air purifier on and off – and control the operating speed. It also alerts you when it is time to replace the filter, every six months (operating time). I’ve written quite a bit about how to choose an effective air purifier, so if you’re not familiar with CADR, AHAM and so forth, get a crash course here. Or consider buying the Blueair Blue Pure 411 (or 211+). These filters carry an AHAM Verifide seal and a CADR. The 411 has a CADR of 120 for dust and pollen. This means that at the top setting the filter produces 120 cubic feet of clean air every minute. For smoke, the CADR is 105. The purifier manages about 5 air exchanges per hour for a small bedroom or nursery, or one every 12.5 minutes. It’s great to have four operating modes so it can be set depending on what’s going on inside your home or with your allergies. So, for example, if you're a hayfever sufferer you might choose a lower setting in winter when there's not much pollen. Or if you're spring cleaning and dust is flying around as you move furniture, a higher may be required. I would also certainly switch it to Boost if I noticed the air quality light was showing red and indicating that the air was quite polluted. Say hello to the Blue family’s smallest and slimmest air purifier, the Blue Pure 411. It contains Blueair’s world-leading filter technology and is designed for rooms up to 15 m² (161 ft²) Just grab it, place it wherever you want, plug it in, and breathe perfectly clean air 24/7. During our tests, our reviewer, Jennifer, found that the Autoreact did a better job of purifying the air rather than cooling it; it took this model some time to bring down the temperature of a room. In fact, by the time the room was showing as having come down in temperature, we no longer needed to be cool/ or we had moved rooms. The 10 speed settings and night time mode were useful for speeding up the cooling and purification of the air, and keeping control of the noise output.

Conclusion

Some air purifiers can also cool and / or heat the room. Both the Dyson air purifiers and the Shark 3-in-1 Air Purifier, Heater & Fan with NanoSeal HEPA in this guide offer such capabilities. We found that it does have a number of small flaws in terms of response times and fan speeds though, and the performance will vary depending on the room size. Besides, it's the AeroTower's dimensions that allows it to cover rooms of up to 818sq ft in size. It's incredibly easy to set up and use, even boasting an LCD panel that clearly indicates the quality of the air in a given room, plus a remote that magnetically attaches to it. We're also a fan of the touch controls on top, despite the fact that they were prone to accidental presses. On top of ensuring that your room is free of harmful particles and allergens, this unit also has a fan function that offers 10 speeds and oscillation – a nice addition to keep the air flowing in the summer. The Dyson Purifier Cool Autoreact gets our vote for the best cooling air purifier. It's also a good option for those who prefer a model without any smart functionality, this model doesn't come with an app. All of the air purifiers featured in this guide have been tested by the editors on TechRadar. They've been reviewed at home (no labs here) in real-life situations, used daily across a minimum of a two-week time frame.
