Blue Pure 411 Auto Air Purifier: Trusted Review & Specs

The Blue Pure 411 Auto is a solid air purifier, and compared to the previous Blue Pure 411, it makes your life even easier. Given that Blueair has released two new versions for its bestselling Blue air purifier, we decide to make a new, proper Blue Pure 411 Auto Review, and we will make a comparison chart for all three versions of the Blue Pure 411.

The Blue Pure 411 Auto has been the best air purifier for 2 years, with an unique and simple style to control.

Blue Pure 411 Auto ranks A- in our air purifier ranking list. We give the biggest and most thorough database of air purifier reviews in the world.

The Blue Pure 411 Auto is a must-have air purifier if you want some smart features on a budget device. So, get ready for our new Blue Pure 411 Auto Review.

Other Blueair’s Air Purifier Reviews

Blue Pure 411 Auto Price

Blue Pure 411 Auto, surprisingly, starts at the same price as the original Blue Pure 411. However, its price has increased to $139 later. None of Blueair’s new air purifiers are cheap, so the budget option like this air purifier is really fantastic for air purifier users.

This is the Blue Pure 411 Auto, so, as you might think, the air purifier will have a Smart Sensor, so you can run the device automatically. It is not identical to the Blue Pure 411, and it even appears more premium than the new Blue Pure 411+; however, the differences are only on the outside.

This is a weird situation for a review; usually, when a new air purifier is released, we will try to answer the question of whether it’s better than the now-cheaper model from the previous year. It seems the Blue Pure 411 Auto is using the influence of the best-selling Blue air purifier, so basically you can skip the model if you don’t need the auto mode.

At this price, naturally you won’t find many air purifiers with Auto Mode like this Blue Pure 411 Auto, except the Airthereal ADH80, Honeywell HPA080 and AeraMax 100. Other popular air purifiers like the GermGuardian AC4825, Levoit Core 300 or Vornado AC350 don’t come with such generous feature. Perhaps we should wait for the new Levoit Core 200S to be the next best budget smart air purifier.

Blue Pure 411 Auto Design and Size

Usually in this section we’d talk about all the new design first, and the Blue Pure 411 Auto is truly improved with the new premium fabric pre-filter colors. The original color is named Arctic Trail, and all colors are inspired by the natural landscapes of Scandinavia. That’s how the Swedish manufacturer tried to make its air purifiers more sleek.

Beyond that, the design of the Blue Pure 411 Auto (and even the Blue Pure 411+), is familiar because it is exactly the same as the Blue Pure 411 from the previous years. The same shape, bottom-to-top airflow system concept and 7.9 x 7.9 x 16.7 footprint are used, and the temptation to copy and paste the old words here is high.

But at the same price, it’s easy to understand why the Blue Pure 411 Auto is an overall better choice. We were mightily impressed with the sleek and beautiful design, don’t forget about the LED indicator right at the middle of this air purifier. The Blue Pure 411 Auto remains most of the simplicity from its previous brother, and makes it fit perfectly in small bedrooms.

To make the air purifier more convenient, Blueair adds a hidden cord compartment below the particle sensor. This velcro-panel will keep the power cord close to the body and out of sight.

The Blue Pure 411 Auto is compact, too, at 3.8 lbs. Everyone can handle the air purifier easily, and that’s why this air purifier is perfect for small rooms.

Blue Pure 411 Auto Filters

Blue Pure 411 Auto uses the same air filtration system as the rest of the Blue family, however, it seems the basic filter of the Blue Pure 411 is more efficient.

  1. Pre-filter – It’s worth noting that the fabric pre-filter of the Blue Pure 411 Auto is outside the air purifier. This is one great advantage of this pre-filter, because you can easily check its status and vacuum or wipe the contaminants out immediately.
  2. Particle filter – Instead of using a True HEPA filter, the Blue Pure 411 Auto runs a polypropylene fiber filter to help capture 99.97% of all allergens as small as 0.3 microns like dust, dust mites, pet dander, pollen and fungi (HEPASilent technology).
  3. Activated Carbon Filter – The Activated Carbon filter is added inside the Particle filter and effective against smoke, odors, gases and VOCs.

The HEPASilent technology of Blueair has improved miles away from the original filter. It is less dense so all Blueair air purifiers have high fan power without loss of performance. Also the Blue Pure 411 Auto is quiet and energy-efficient.

In Breathe Quality, we all love the air filters from Blueair. Polypropylene fibers are free of chemicals and naturally anti-bacterial. Most importantly, not like the cheap air purifier, this Particle filter is recyclable.

It uses the same air filter as the Blue Pure 411, but it seems the manufacturer has improved the Particle filter. Its efficiency is quite better than the last test’s result of us. You can check the below chart for comparison between the Blue Pure 411 Auto and Eureka Instant Clear NEA120, Filtrete FAP-C02WA-G2 and Levoit LV-H128.

Using the same old air filter is a relief, because you can find it easily on any online retailers. It is just $21, but you need to replace it every 6 months.

Blue Pure 411 Auto Room Coverage

The room coverage of the Blue Pure 411 is (unintentionally) larger than the recommendation of the Blue Pure 411. Checking the actual CADR rating, I don’t think it has higher fan power than the original version, but the suggested 190 square feet of Blueair is still legit.

The ACH of Blue Pure 411 Auto is 5X. Blueair is a well-known brand in creating powerful air purifiers, and even its Blue Pure 411 Auto is no exception with a high air changes per hour rating.

The CADR of Blue Pure 411 Auto is exceptional at 107 Dust/ 123 Smoke/ 96 Pollen (cfm). It is a bit better than the original version, but in compared with the Blue Pure 411+, it is nearly the same.

Blue Pure 411 Auto Sound

One of the most reasons to buy the Blue Pure 411 Auto is its great silent operation. With smart making of air filter, the Blue Pure 411 won’t resist the airflow much like ordinary air purifiers, thus it is quieter.

The lowest noise level recorded on the Blue Pure 411 Auto is 18 decibels (dB) and the highest is 48 decibels (dB). On lowest speed, the noise level is even below the rustling leaves’ level. You won’t hear anything from such mode for sure.

Blue Pure 411 Auto Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?” An air purifier is designed to run for a long time to be efficient. Therefore power consumption is always one important criteria when you decide to buy one air purifier.

Blue Pure 411 Auto could be the best energy-saving air purifier in the world, as it operates with only 2 to 10 watts. Yes, this air purifier is rated by Energy Star, too.

If you use the Blue Pure 411 Auto for 8 hours each day, you just only need to pay $0.7 to $3.5 each year. Woahh, impressive!

Blue Pure 411 Auto Additional Features

As the name implies, the Blue Pure 411 Auto is a smart air purifier. It has both dust and gas sensors, and it can detect real-time temperature and humidity.

Other than that, the Blue Pure 411 Auto still lives up to the core of the Blue family – simplicity. It has only one touch to control the whole air purifier.

Blue Pure 411 Auto Customer Service

As one of the best air purifier brands, Blueair focuses strongly on customer service. With a lot of local stores and dedicated support via phone and email, you are guaranteed to reach its customer service as soon as possible.

Remember only one thing: you need to complete the Product Registration form within 60 days of purchase or register through the Blueair Friend mobile app to secure the 5-year warranty. Otherwise, you only benefit from a 1-year warranty. Moreover, do not attempt to bring the air purifier outside of the United States or Canada, or your warranty will be void immediately. All Blueair warranties are non-transferable.

Blueair air purifiers from the Blue family have only a 2-year warranty from the date of purchase (with valid proof of purchase). One quick reminder: Blueair doesn’t cover warranties from third-party sellers, so buying from Breathe Quality’s deals is highly recommended.

Our verdict

At the moment, the Blue Pure 411 Auto is one of the best air purifiers you can get for around $100 to have the Smart Sensor. Though the air purifier doesn’t have high CADR rating like the Levoit Core 300, it is enough to beat any small room.
