Product Information

My first impressions were excellent as this purifier is lightweight (under 4 lbs!), portable, and so easy to set up. The purifier was pretty much ready to go, right out of the box. With one of the two pre-filters already in place, all I had to do was slot the top (white) section of the unit on and turn it to secure the catches. After plugging it in (and reading the manual), I pressed the top center circle to start the purifier. 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. In addition to the smokey room test, we also evaluate the unit's CADR or clean air delivery rate. While many companies provide this information in a single number, the Blueair Blue Pure 411 breaks it up into three critical categories of air contamination — these are smoke, dust, and pollen. The 411's CADRs are about average for the class at 105 (Smoke), 120 (Dust), and 120 (Pollen). Noise 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.

A compact cylinder made of a choice of colourful plastics, the Blue Pure 411 is beautifully simple. It stands just 42.5cm tall and has a diameter of 20cm. It's among the simplest and most compact air purifiers you can get. 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. During testing, we found that an app can deliver greater insights to the air quality inside the home. There's only so much information that the display panel can show, and if you want to monitor the air quality over a time period, then this is only possible through app support.

Conclusion

The Blueair Blue Pure 411 Auto arrives set up and ready to go out of the box. All I had to do was familiarize myself with the controls, which didn’t take long since there’s just one button and four settings. The air quality light was showing blue at first, but just one spray from a can of anti-perspirant deodorant in the area above the purifier, saw it change to orange within a few seconds. This tells me that the air quality sensors are doing their job. What else can I tell you about the Blue Pure 411? Changing the filter is a simple matter, which is good since you'll be doing it a couple of times a year at least. The filter is a three-layer affair, with an outer filter to catch larger particles and dust, a fine HEPA filter to remove particles and allergens and a carbon filter to deal with fumes. The Blueair Blue Pure is very quiet on its lowest setting. You’ll know it’s on by the single white light illuminating a third of the center circle. To bump it up to its middle setting, press the circle again and a second light will come on. For the highest setting, press a third time, and the circle of light will be complete. To turn it off, press the circle again and all the lights will go out as well. This center circle light will glow red when it’s time to change the filter. 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. part filtration system: captures 99% of common airborne PM 2.5 pollutants (allergens, odors, smoke, mold spores, dust mites, pet dander

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. 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.

Value

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. As far as I can tell, the warning to change the filter is based on time passed rather than sensing how saturated with allergens, particles and smoke it is, so it's probably wise to keep an eye on it if you're using it in a more polluted area.
