Blue Pure 411 Design
The most exciting part of the design is the fabric pre-filter, which can be bought in various colors. You can get a black fabric filter, and then you will have a black and white air purifier, which are colors that can be used in any room.
However, if you love to use wild colors, there are many to choose from. Dark Shadow and Diva Blue are usually shipped by default, but if you like, you can order separately other colors like Buff Yellow, Crystal Pink, or Lunar Rock.
The construction of Blueair 411 is well done and reminds me of a Bluetooth speaker. On the top are holes for better airflow, and in the middle is one big button. The button is used to control everything about the Blue Pure 411. Airflow is excellent, thanks to 360-degree air suction. As well on all sides, you will find the Blueair logo, which proves that the company wants you to know that they are very proud of their product.
Blueair Blue Pure 411 air purifier is light, which allows you to move it from one room to another easily. As already mentioned, the cylindrical shape allows this air purifier to blend in any room. And it will enable you to use it in any part of the room no matter how little space you have.
Because of its small size, the filter is almost all over the construction, which in return gives a higher performance at removing unwanted pollution. Small size is also disadvantaged because if you have little kids, they may bump the device and flip it over. The good news is that on the bottom is a grip that keeps the air purifier stable.
One Button For Ultimate Control
There is only one button on the air purifier, and with that button, everything is controlled. Some people may think that there is an App or Wi-Fi connectivity that gives you additional features, but there is not. Blue Pure 411 is simple to use, and there is no magic behind it. You turn it on, and it works, what else do you need?
Some people may find lights on the air purifier disturbing during the night. You can contact Blueair directly and ask for NightCap. It is a little sticker that covers the lights.
Blue Pure 411 has 3 fan speeds. To start the air purifier, push the button. Push it again, and it will start working on the second speed, one more push, and the air purifier will use maximum speed to filter air. To shut it down, click the button again after the maximum speed mode.
I must say that I was a bit disappointed because there is no beep on the button push. However, the light around the button is strong enough, and you will notice the change in the speed.
On the other hand, it has an auto-start feature. This feature means that if there is a power outage or if you use the power switch timer, you can automatically start the air purifier. As soon as there is power, the air purifier will start to work. Besides, Blue Pure 411 will work ideally with a smart air plug.
Not pressing the button for 5 seconds will dim all lights on the air purifier. With the next push on the button, the light will come back. Speed will not change when the lights are off. First, you need to bring them back, and then the next push on the button will change the speed.
Size and Dimensions
Blueair 411 is lightweight and has only 3.35 lb. It is one of the lightest air purifiers on the market. There is no handle on it, so you may think it will be hard to move, but the lightweight allows you to take it with you everywhere you go easily. Thanks to its small dimensions (16.7 x 8 x 8 inches), it can easily be put on a table, desktop, cabinet, or any other small piece of furniture.
Blueair Blue Pure 411 needs to be placed four inches from the wall or any other object to provide unobstructed airflow. Kids need to be careful with this device because they may push fingers in the holes on the air purifier and hurt themselves that way.
Accessories and Parts
Once you buy Blueair 411 in the package, you will get the air purifier, particle filter, and carbon filter, fabric filter (Diva Blue), as well an additional fabric filter (Dark Shadow), user manual, and of course warranty card.
Room Coverage and CADR
Thanks to the 360-degree airflow and brilliant motor performances, Blue Pure 411 can change the air 5 times in one hour if it runs in a room that is 161 sq. ft. large.
It has excellent CADR scores. Below is a table with the Clean Air Delivery Rates.
|Smoke||105 CFM (180 m3/h)|
|Dust||120 CFM (200 m3/h)|
|Pollen||120 CFM (200 m3/h)|
Blueair Blue Pure 411 Video Review
Blueair Blue Pure 411 is one of the lightest air purifiers on the market. I did many tests on this device. Noise and performance tests have proven that this device can be very useful in some situations. Also, the unique design and ability to choose colors make this air purifier popular. Watch the video and learn all you need about this air purifier, how to use it, and how to change the filter.
Thanks to a carbon filter that is covering almost all parts of the air purifier, the odor will be removed at rapid speed. It would be better if it has an activated carbon filter, but unfortunately, it doesn’t have one. Blue Pure 411 uses a fibrous carbon filter for filtering gases instead of an activated carbon filter that contains pellets.
Removes 99% of Particles
Blueair Blue Pure 411 is tested, and it can remove 99% of particles down to PM 2.5. Smoke, bacteria, dust, mold, pet dander, cooking odors, viruses, pollen, and other pollution that is hovering in the air can be removed with the Blueair 411.
Low Energy Consumption
Believe it or not, Blue Pure 411 only uses 10W of energy when it is on the highest setting. Many old devices use that energy on standby.
Blue Pure 411 doesn’t have an integrated automatic work or timer, but with a smart plug, you can create your own timer. You can do that because as soon as the air purifier gets power, it will start working, which allows automatic work and a timer.
Blueair Blue Pure 411 remembers last fan speed, and if there is a power outage, it will continue its work as soon as the power comes back at the same speed.
The warranty on Blueair products is decent; you will get a one or two-year warranty. However, if you register your product on the Blueair website, you will get an additional warranty.
Easy Filter Change
Filters can be easily replaced by anyone, no need for a tech-savvy to help you. Instructions are simple, and everyone can do it.
Blue Pure 411 Filters
As already said, Blue Pure 411 uses a three-stage filtration system. The pre-filter is a simple fabric that is easily replaced. It is also washable, and if you like, you can buy additional fabric filters to match your room style.
Particle and carbon filters are combined together and are used to remove particles and odors.
Particle + Carbon Filter
I must say from the start that the filter that Blue Pure 411 uses is not a True HEPA filter since it removes 99% of airborne particles, and to be certified, as a True HEPA filter, it needs to remove 99.97%.
The carbon filter is good enough and can remove nasty odors in a decent time.
The ability to change pre-filter and match it to the style of your room is great benefit of this Blueair air purifier.
Pre-filter is essential, and its job is to catch large particles that may represent trouble to fine filters. Pre-filter in Blue Pure 411 is unique, it is easily replaceable, washable and you can buy additional ones in various colors. You can even use a vacuum cleaner on it. You will notice dust on the pre-filter, and as soon as you see it is too dirty, you can clean it.
Pre-filter is not replaceable; it is washable. As soon as you see, it has dirt, clean it.
How to Change the Blue Pure 411 Filter in 6 Easy Steps?
Filter changing is easy and is one of the great features of the Blue Pure 411 air purifier. The filter replacement usually depends on how often you use the air purifier and how bad the quality in your room is. You can wait for a red light to let you know that filter needs replacement, or you can replace it after 6 to 8 months, which is a recommended time for a replacement.
Before starting with the filter changing process for the Blue Pure 411, you need to make sure the air purifier is not attached to the power.
Total Time: 10 minutes
Remove the top cylinder
Remove the top cylinder off by rotating it counterclockwise.
Remove the fabric filter
Remove the fabric filter (pre-filter). After taking off the pre-filter, use your vacuum cleaner to remove the particles, or wash it in the washing machine.
Remove the particle and carbon filter
Remove the particle and carbon filter. Do it by removing the filter shelf and pulling the the particle and carbon filter upwards.
Place a new filter in
Place a new filter. Take the plastic bag off a new filter, and place the new filter.
Prepare the air purifier for work
Prepare the air purifier for work. Return the filter shelf and pre-filter, and return a top cylinder on the top by rotating it clockwise.
Reset the filter changing indicator
Reset the filter changing indicator. Hold the button for 5 seconds to reset the filter replacement timer. When the color changes from red to white, you are sure that you did everything well.
I have tested Blue Pure 411 noise levels at different fan speeds. The air purifier has three fan speeds. The third speed is loud and generates weird noise. It is hard to listen to that noise level for a longer time. The second speed is much better.
However, on the first speed, the noise level is as low as it gets, you won’t even notice it. At first speed, you can easily use it in the bedroom. In the table below, you can see noise results. In my opinion, the Blueair should reduce motor noise levels, because it’s too loud at the highest speed.
|Speed 1||40.6 dBA|
|Speed 2||54.5 dBA|
|Speed 3||67.5 dBA|
I did performance tests as well. This low energy-consuming air purifier did a decent job in some of the tests. I did experiments in different room sizes.
The recommended room size for the Blue Pure 411 is 161 square feet, with 5 air changes per hour. On the third speed, performance is best, but so is the noise.
Airflow is strong and fluctuates from 35 to 120 CFM depending on the speed. In all tests, I used the third speed. At that speed, dust from the room will be gone fast, and in only a few days, you will notice there is less dust in the room. These tests I did are real-life tests, and there were no lab tests done by me.
For best results, start it on third speed and let it run for some time, after that you can switch it to the first speed.
194 sq. ft. Room Test
This room is a bit larger than the recommended one. But still, the device did a great job. In only one hour, it dropped AQI from 133 to 6. That means the air quality was improved by 95%. I let it run for a longer time, and AQI was additionally dropped. Air quality was stable after that, and there were no signs of air pollution increase.
|#||Starting Baseline||After 60min|
320 sq. ft. Room Test
Double the size of the recommended room; I was skeptical about what this little device can do. But Blueair Blue Pure 411 shows no mercy to pollution and reduced AQI from 131 to 13, which is 90% better air quality.
I must say that the test was done on the third speed; on the first speed, the results would not be so good.
|#||Starting Baseline||After 60min|
It uses so little energy that it is better to stay on than to shut it down. The maximum energy consumption is 10W. On first speed uses only 0.6W. Standby consumes 0.3W. Your energy bill will stay the same even if you run it all the time.
If used in the bedroom, it will drastically improve sleep quality.
In other words, if you run it for 24h and 30 days, you will pay less than a dollar. Without a doubt, the Blue Pure 411 air purifier deserved the Energy Star certificate. The highest operating cost is filter replacement.
Energy consumption is a valuable factor when choosing an air purifier. Other than this Blueair air purifier, there are many different air purifiers you can look for, such as Levoit Vista 200 and Airdog X3, that consume less energy than the average air purifier consumes.
|Speed||Power Usage (W)|
Does Blueair 411 produce ozone?
No, it doesn’t. It doesn’t have an ionizer or any other filtration type that could produce ozone.
Can you leave the Blue Pure 411 working at night?
Yes, you can leave it at night. I suggest you use a NightCap if you want to use an air purifier during the night. That is a little sticker that covers the lights.
How long do the Blue Pure 411 filters last?
It could last up to 8 months, but it depends on how often you use the air purifier. Anyway, you should change it between 6 to 8 months.
Does Blue Pure 411 use a True HEPA filter?
No, it uses the HEPA filter instead. No, it uses the HEPA filter instead. Although it doesn’t use a True HEPA filter, it will remove 99% of particles down to PM 2.5.
Does Blueair 411 have an ionizer?
Yes! I got a confirmation from Blueair’s support that all their air purifiers use a HEPASilent technology, which means they all have a built-in ionizer. But, the good thing is that this model is CARB certified.
Pros and Cons
To revise, here are the advantages and disadvantages of Blue Pure 411:
Your FAQ states that it definitely does not produce ozone as it has no ion function. Just to confirm.. the reason that this device claims such a high filtration without a true hepa filter is because it uses a combination of silent hepa tech and de ioniser which you claim it doesn’t. This is not hidden and is well advertised on all selling sites including bluair site. It has however passed tests which show it may actually reduce ozone.
The review also mentions it ships with two pre filters. On buying one it comes with the diva blue pre-filter only and I confirmed this with bluair whose customer support is actually great. The 211 model comes with both filter colours as standard.
