Blueair Blue Pure 411 Vs Hathaspace HSP001

In this comparison, I will compare two almost entirely different devices, the Blueair Blue Pure 411 and the Hathaspace HSP001.

When we look at the options these air purifiers offer, we can notice many differences and roughly know what to expect with which device.

The Blueair 411 and Hathaspace HSP001 do not have many standard options, so I will describe some of the most essential options from both devices in the following chapters.

Device Control

The Blueair 411 is a very minimal device that uses only one button to fully control all the device options. Hathaspace HSP001, on the other hand, offers a multitude of options, including 6 buttons.

Besides, Hathaspace has a remote controller, with which you can control all the options on the device from a chair.

Smart Sensor and Air Quality Indicator

Hathaspace features a smart sensor that measures current air quality in real-time. The smart sensor reads dust particles in the air, and based on that, it determines what the current air quality is. These readings are shown on the Air Quality Indicator located on display. Blueair 411 does not have a smart sensor.

Auto Mode

Hathaspace HSP001, unlike Blueair 411, has an auto mode option.

Auto mode works in combination with the smart sensor. When the air purifier is in auto mode, it will switch the motor speed depending on the room’s current air quality. This is an excellent option with which you can turn on the device and “completely forget” about it.


Hathaspace stands out for another functionality, and that is the Ionizer that is built into the device. I do not use Ionizer, and that is why I really like the fact that with Hathaspace. The Ionizer is turned off by default and is turned on as needed or desired by the user by pressing the “Anion” button.

Filter Reset Indicator

This is an option that only adorns the Blueair 411 air purifier. I think it’s a big minus that Hathaspace doesn’t offer this option, mainly because of the benefits and ease of using the device that the “Filter Reset Indicator” offers.

Basically, the filter reset indicator will notify you when it is time to replace the filter. That way, you don’t have to manually worry about when it’s time to replace the filter.


These two devices are entirely different in shape, so the airflow is a bit different. The Blueair 411 is circular in form. The filter is located on the underside and occupies two-thirds of the device. This means that Blueair draws air through the surface occupied by the filter. The filtered air then exits through the grilles on the top of the device.

Hathaspace HSP001 is rectangular in shape. The device draws air through openings in the front. The air is then filtered and exits through the grilles located on the upper side.

When it comes to filtration, these two devices are very different.

The Blueair 411 uses 3-in-1 filtration without an ionizer or some additional filtration stages.

At Blueair, the first stage of filtration is interesting. The washable pre-filter is available in a variety of colors. This is a great stylish detail that can help the device fit into almost any environment.

I don’t like that the Blueair 411 doesn’t use a True HEPA filter; it uses a HEPA filter. The gas filter at Blueair is a fibrous filter coated with carbon.

Hathaspace HSP001 uses 5-in-1 filtration, which also includes an Ionizer, which is activated as needed. Suppose I were to compare the filters on these two devices, in my opinion. In that case, the most significant difference is that Hathaspace uses a True HEPA filter. It uses carbon pellets that are very densely arranged and of very high quality, to everyone’s surprise. 

However, let’s check out the performance tests and see which filtration is better and which air purifier is better at purifying the air.

How to replace filters on these products?

With the Blueair 411, the filter changes on average between 6-8 months. With the Hathaspace HSP001, the filters are changed on average between 4-6 months.

I would like to emphasize that Hathaspace does not have the “Filter Reset Indicator” option, which means that you will have to manually count when is the time to replace filters.

The Blueair 411 has this option, so you won’t have to worry about when it’s time to replace the filter; the device will let you know.

The Hathaspace is one of the quieter devices I’ve had a chance to test so far when we consider the volume the motor produces at all speeds.

Overall, the HSP001 is much quieter than the Blueair 411, especially at top speed, where the difference in volume between the two devices is greatest.

The most significant difference when we compare these two devices’ volumes is that Hathaspace HSP001 produces pleasant sound at all speeds. In contrast, Blueair 411 has a lovely sound at the first two speeds, while on the third, it makes a slightly louder and more unpleasant sound.

You can see the volume ranges of these two devices in the table below.

Product Noise Range (dBA)
Blueair 411 40.6 – 67.5 dBA
Hathaspace HSP001 41.3 – 49.3 dBA


For a complete comparison, perhaps one of the most important sections is the performance test. Hathaspace HSP001 is designed for rooms up to 350 sq. ft. while Blueair 411 is designed for rooms up to 161 sq. ft.

Although Hathaspace is designed for a room more than twice the size of Blueair, I tested the devices in rooms of identical dimensions and in similar conditions.

Whether the Blueair, although intended for smaller rooms, can match this Hathaspace model can be found out in actual tests.

194 sq. ft. Room Test

I tested the devices in a room of 194 sq. ft.; I tested them separately.

During the test, the machine was running at the highest speed all the time.

* Data measuring time is 60 minutes.

Blueair 411 improved the air quality in this room after 60 minutes by about 95%, which is an excellent result, and in a way expected from an air purifier like this.

In a room of the same dimensions, also in 60 minutes, the Hathaspace HSP001 lowered the AQI from 134 to 8, thus improving air quality by about 94%. This is also an excellent result.

Both devices performed excellently in this test. I have no objections to the operation of either device.

320 sq. ft. Room Test

I did the next test in a slightly larger room, which is 320 sq. ft. This room is almost twice the size recommended for the Blueair 411 and somewhat smaller than the recommended dimensions for the Hathaspace HSP001.

* Data measuring time is 60 minutes.

In the first test, the Blueair 411 lowered the AQI from 131 to 13 in 60 minutes, improving air quality by about 90%. This result is unexpectedly good, especially if you consider that the room is much larger than the recommended dimensions.

In this test, the Hathaspace HSP001 improved air quality by about 91% in 60 minutes, thus lowering the AQI from 129 to 11.

Operating Costs

The Blueair 411 is an air purifier that has a motor of 10W, while the Hathaspace HSP001 has a motor of 45W.

From the motor’s power, it is straightforward to conclude that Blueair has a much smaller energy consumption by several times.

If you leave Blueair running at maximum speed, 24 hours a day, and so on for a month, the device will spend less than $ 1. Hathaspace will spend about $ 3 at the highest speed in the same conditions, which is 3 times more than Blueair.

Product Wattage Range (W)
Blueair 411 0.3 – 7.6 W
Hathaspace HSP001 1.4 – 34.8 W

Also, there is a big difference in the filter replacement cost and the time it takes to replace it.

Replacement filters for Blueair 411 are cheaper and last longer. When we take all of the above into account, we can conclude that the maintenance costs for Blueair 411 are much smaller than the Hathaspace HSP001 over one year.

Which one is the winner?

Both devices have their advantages and disadvantages. But if I had to categorize them, then I would say that the Blueair 411 is an air purifier for people who are highly fond of minimalism, while the Hathaspace HSP001 is for people who want a lot of advanced and additional options.

However, these are matters of taste, not something that decides victory in this clash. Taking all the parameters into account, in my opinion, the Blueair 411 is a much better choice to buy than the Hathaspace HSP001

The reasons are numerous. I would single out: excellent performance; Blueair is several times smaller energy consumer than Hathaspace, filter reset indicator, and cheaper replacement filters..

In any case, if you opt for Hathaspace, you will not go wrong either; just keep in mind the maintenance costs as well as the lack of filter reset indicator.
