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! 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). Unlike many filters, the Blueair Blue Pure 411 comes with a polypropylene filter that can be easily replaced and recycled. Because the pre-filter is external, though, you can easily remove and wash this, meaning it never needs replacing. And if you keep the pre-filter in good shape, with regular vacuuming and cleaning, this will help extend the life of the 2 nd and 3 rd stage filters, helping to further save resources. The size and appearance of the 411 Auto air purifier where, in my opinion, Blueair has hit the spot. First, as a floor-standing air purifier it’s quite compact, which will make it suitable for most spaces. It weighs just 3.8lbs / 1.68kg, too, so is lightweight and easy to move from room to room.

And while it’s true that some of the fans come with filters that enable them to emit purified air, these can be expensive. As such, one of the best air purifiers is an excellent option if air quality is the priority. Although, note that it works via a fan pushing air out of the top of the unit, moving air around the room. However, an air purifier isn't just brilliant for keeping allergies at bay; it's useful for reducing strong odors from activities such as cooking, painting or burning a candle. Exposure to these particles over a long period of time can trigger short-term health effects, such as eye, nose, throat, and lung irritation, coughing, sneezing, runny nose, and shortness of breath.

To better serve our readers, we have started answering some reader questions in dedicated blog posts.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. As for those wildfires, it will be interesting to see how this filter performs if we get a lot of smoke again like 2020. Subjectively, it performed well in 2021, keeping our indoor air clear on the smokiest days. I didn’t have an air quality monitor at the time, however, though I do plan on acquiring one this summer. If/when I get readings, I’ll update this post with results.

See https://www.quietmark.com/ for further information 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.

Yamaha's soundbar bundle delivers all you could need, including one of the best subwoofers at this priceWe keep the purifier on the highest setting as it’s an excellent white noise machine. The Blueair not only helps to soothe our baby to sleep, it also drowns out the noise of the wolf that lives next door. That’s right, we have a wolf hybrid neighbor who howls for a large part of the night (and day). Without the air filter, I’m constantly woken up with spiked adrenaline (not awesome in pregnancy). With the air purifier, I sleep right through the howling. During testing, Helen was impressed by the combination of its simplicity and stylish good looks. She also noticed improved air quality and freshness without any intrusive sound or excessive energy consumption. However, keep in mind that if you have very large rooms or open-plan areas then it won’t be up to the task. 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.
