In this article, I will compare the Blueair Blue Pure 411 and the Hathaspace HSP001.
The Blueair 411 is designed with minimalism in mind and lacks advanced features. In contrast, the Hathaspace HSP001 offers innovative and practical features, such as an air quality sensor and auto mode, which I find particularly appealing.
The Hathaspace also covers much larger rooms than the Blueair. Whether you prefer a minimalist approach or a product with more options, this comparison will give you a comprehensive overview of both the Blueair and Hathaspace air purifiers.
I will present and compare their performance in various tests, including noise levels, power consumption, and other key factors. So, keep reading!
Our Verdict
Both devices have their advantages and disadvantages. If I had to categorize them, I would say that the Blueair 411 is ideal for those who appreciate minimalism, while the Hathaspace HSP001 is better suited for those who prefer advanced features and additional options.
However, these preferences are subjective and don’t determine a clear winner in this comparison.
Taking all the parameters into account, in my opinion, the Blueair 411 is the better choice overall. There are several reasons for this, but I would highlight its excellent performance, better-optimized motor, faster results in our smoke test, the inclusion of a filter reset indicator, and the more affordable replacement filters.
That said, if you choose the Hathaspace, you won’t be disappointed either. Just keep in mind the higher maintenance costs and the absence of a filter reset indicator.

Performance Test – Comparison
One of the most important sections in a comparison is the performance test. The Hathaspace HSP001 is designed for rooms up to 250 sq. ft. (23 m²), while the Blueair 411 is designed for rooms up to 161 sq. ft. (15 m²).
Although the Hathaspace has a slightly higher CADR and larger room coverage, we tested both in identical rooms.
In the first test, performed in a 194 sq. ft. (18 m²) room, we evaluated their performance at maximum speed using the Temtop laser particle monitor.
Particle Removal Tests - Comparison
We placed the Blueair 411 Vs Hathaspace HSP001 in two separate tests and measured their performance using the Temtop laser particle meter.
The Blueair 411 reduced PM2.5 particulate matter from 101.5 to 4.2 µg/m³, achieving a 95% improvement in air quality. Under the same conditions, the Hathaspace HSP001 improved air quality by 94%.
In the second test, performed in a room much larger than recommended for both air purifiers, both devices delivered impressive results. This time, the Hathaspace HSP001 performed slightly better, improving air quality by 91%, compared to the Blueair 411’s 90% improvement.
Overall, both air purifiers performed exceptionally well in both tests, leading us to conclude this battle as a draw.
Smoke Box Test – Comparison
If we compare the CADR and room coverage of these two devices, we might assume that the Hathaspace would perform better in this test. Additionally, the Hathaspace has more filtration layers and uses a superior carbon filter.
However, in practice, the results were quite different. Despite being smaller and less powerful, the Blueair 411 removed all the smoke from the glass box in just 20 seconds, while the Hathaspace took more than twice as long—specifically 41 seconds—to achieve the same result.
Although this outcome was somewhat surprising, it reinforces that neither device’s capabilities should be underestimated, and the Blueair’s performance in this test is a clear testament to that.
Noise Level Test – Comparison
The Hathaspace is one of the quieter devices I’ve tested so far, especially considering the noise level at all speeds.
It’s also a device I frequently recommend to people looking for an air purifier for the bedroom. At its lowest speed, it produces 41.3 dBA of sound, while at maximum speed, it reaches 49.3 dBA.
In contrast, the Blueair 411 is noticeably louder, particularly at maximum speed, where it produces 67.5 dBA, while at its lowest speed, it produces 40.6 dBA.
Noise Levels - Comparison
Comparison of noise levels at all fan speeds between the Blueair 411 Vs Hathaspace HSP001 air purifiers.
The most significant difference in noise levels between these two devices is that the Hathaspace HSP001 produces a pleasant sound at all speeds.
Meanwhile, the Blueair 411 has bearable noise at the first two speeds, but at the highest setting, it becomes noticeably louder and somewhat unpleasant.
You can see the noise level ranges for both devices in the table below.
| Fan Speed | Hathaspace HSP001 (dBA) | Blueair 411 (dBA) |
|---|---|---|
| Speed 1 (Low) | 41.3 dBA | 40.6 dBA |
| Speed 2 (Medium) | 43.9 dBA | 54.5 dBA |
| Speed 3 (High) | 49.3 dBA | 67.5 dBA |
Overall, the HSP001 is much quieter than the Blueair 411, especially at maximum speed, where the difference in noise level is most evident.
Operating Costs – Comparison
The Blueair 411 has a 10W motor, while the Hathaspace HSP001 has a 45W motor.
Based on motor power alone, it’s easy to conclude that the Blueair consumes significantly less energy—nearly five times less.
If you run the Blueair at maximum speed, 24 hours a day for an entire month, the energy cost will be less than $0.67. Under the same conditions, the Hathaspace will cost around $3.05, which is three times more than the Blueair.
Monthly Power Consumption Cost - Comparison
Comparison of monthly power consumption costs for the Blueair 411 Vs Hathaspace HSP001 air purifiers at all fan speeds.
There’s also a notable difference in the cost and lifespan of replacement filters. The replacement filters for the Blueair 411 are cheaper and last longer.
| Fan Speed | Hathaspace HSP001 (W + $/month) | Blueair 411 (W + $/month) |
|---|---|---|
| Standby | 1.4W ($0.12) | 0.3W ($0.03) |
| Speed 1 (Low) | 20.3W ($1.78) | 0.6W ($0.05) |
| Speed 2 (Medium) | 26.5W ($2.32) | 2.4W ($0.21) |
| Speed 3 (High) | 34.8W ($3.05) | 7.6W ($0.67) |
Considering all of these costs, it’s clear that the maintenance costs for the Blueair 411 are significantly lower than those for the Hathaspace HSP001 over the course of a year.
Filtration Technology
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 Air Purifiers?
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.
Features Overview
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.
Ionizer
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.
Airflow
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.
