Medify Air MA-15 Vs Blueair 411 – Trusted Comparison!

Today’s comparison is attractive, especially since it’s the first time I’ve compared Medify Air and Blueair companies. In this comparison, I will compare Medify MA-15 Vs. Blueair 411 air purifiers.

What is interesting about these two companies is that they are predominantly focusing on air purifier products and that they have a huge selection of different air purifiers on the market.

When it comes to these two models, the most significant difference that can be noticed is in the design and the advanced features that each of these two models possesses. The Blueair 411 is a minimalist air purifier, which does not have many advanced functions. It is intended for rooms up to 161 sq. ft.

Medify Air MA-15 is an air purifier that offers slightly more advanced options than Blueair. This model is designed for rooms up to 330 sq. ft. Medify is available in white and silver colors, while at Blueair, the choice of colors is a bit specific. The pre-filter takes up 2/3 of the device, and it can be purchased in over 5 different colors, which means that in this case, customers really have a choice.

Below I will compare everything regarding these two models. I will show which device performed better on the tests, which is quieter and more economical, and in the end, I will announce the winner.

Features Overview

As I mentioned at the beginning of the comparison, the Blueair 411 is a very minimal device, while the Medify Air MA-15 is a slightly more advanced air purifier that uses some advanced options.

What I like is that both devices have a filter reset indicator, which in my opinion, is a crucial thing for a modern air purifier. The Blueair 411 uses only one button to control the device fully, while the Medify MA-15 uses several buttons arranged horizontally. The buttons on both devices are responsive to touch and are located on the top of the device.


The first feature that sets the Medify MA-15 apart from Blueair is the timer. This is a great option that makes it easier for many users to use the device.

The timer allows you to set a time when the device should turn off. The timer can be set to 1h, 2h, 4h, or 8h.

Child Lock

The next feature that is also only available on the Medify model is child lock. This is a great option to ensure that someone does not accidentally change fan speed, turn off or change settings on the device. When the child lock is active, all other buttons on the device are locked and will not respond when pressed.

Personalized Pre-filters

Still, the Blueair 411 also has some features that make it unique and that set it apart. One, perhaps the most frequently mentioned feature, is the ability to change the pre-filter.

Namely, Blueair offers a choice of over 5 different colors, which you can buy and combine with your device. This will make it easier to style Blueair in any environment.

Filter Reset Indicator

As I mentioned before, I really like that the Medify MA-15 and Blueair 411 have a filter reset indicator. It is simply inconceivable to me that a modern air purifier does not have this option and that the user has to manually monitor when it is time to replace the filter.

As for the filter reset indicators, it works on a simple principle. The air purifier will notify you when it is time to replace the filter. After which, you need to replace the filters on the device and reset the filter reset indicator. Note that with Blueair, the pre-filter does not change; it needs to be washed.


The airflow in these two models is somewhat different. Blueair 411 is circular in shape, open on all sides. Therefore, the device draws air through openings that occupy an area of ​​almost 2/3 of the device. The air is then filtered and exits through tiny holes at the top.

The Medify Air MA-15 is designed somewhat differently. This air purifier uses two identical filters that are arranged on the sides. So the device draws in air from the sides, which is filtered and then exits through the openings on the top.

Filtration Technology

When it comes to filtration, Medify MA-15 and Blueair 411 also differ a lot. Medify MA-15 uses two identical filters, which are placed on the sides of the device. Both devices use 3-stage filtration. The first stage of filtration in both devices is the pre-filter. The difference is that the Blueair pre-filter is washable and much easier to maintain.

When it comes to the particle filter, there is also a big difference because Medify uses the True HEPA filter while Blueair uses the HEPA filter. A true HEPA filter is much more efficient. It has been proven to collect finer particles than a regular HEPA filter. When it comes to a carbon filter, Medify uses carbon pellets, while Blueair uses a fibrous filter coated with carbon. I would add that the filter at Blueair is much larger when it comes to filtration, even though Medify uses two filters.

How to replace filters on these two devices?

With Medify Air MA-15, the filters are changed on average between 3-4 months.

With the Blueair 411, the situation is somewhat different; the pre-filter is permanent and does not change. The HEPA and Carbon filter changes on average between 6-8 months.

Blueair has proven to be a much more serious device when it comes to filters; they are larger and last longer. Both devices use a filter reset indicator, so you won’t have to worry about when it’s time to replace the filter. The device will let you know.

Noise Test

Both devices have three operating speeds. What I don’t like is that not one of them has a sleep mode. However, Blueair is very quiet at first speed and is almost quieter than many air purifiers with sleep mode, so the lack of sleep mode won’t be a problem.

Medify, on the other hand, is much quieter than the Blueair 411 at the highest speed. Honestly, both devices are very loud at third speed, but if I had to choose, then I would say that Medify produces a slightly more pleasant sound than Blueair.

I think you will be able to use either of these two products at first speed in the bedroom without any problems. The table below shows the volume ranges of these two air purifiers.

Product Noise Range (dBA)
Medify Air MA-15 41.2 – 61.1 dBA
Blue Pure 411 40.6 – 67.5 dBA

Performance Tests

Medify MA-15 is designed for rooms up to 330 sq. ft. which is much more than the Blueair 411, which is designed for rooms up to 161 sq. ft.

However, due to identical CADR’s, I tested these two devices in similar rooms. Therefore, I will very easily compare the performance and make a conclusion which product is better. Each test is separate, and the duration of each test is 60min. I measured the air quality with a Temtop device to read the current air quality.

194 sq. ft. Room Tests

I tested both devices in a 194 sq. ft. room. I did the tests separately, and each device worked at the highest speed all the time. The Medify MA-15 improved air quality by about 92% in 60 minutes of operation, while the Blueair 411 improved air quality by about 95% at the same time.

Blueair performed better in this test and improved air quality by a percentage more than Medify.

320 sq. ft. Room Tests

In the second test, in a room of 320 sq. ft., I did an identical test.

Blueair lowered the AQI from 131 to 13 in 60 minutes at the highest speed, thus improving air quality by about 90%.

Medify has improved air quality by about 90% in the same period.

There is not much to say here; the devices performed very well and showed equally good performance.

Operating Costs

Electricity consumption is an essential part when choosing an air purifier.

Some will be pleased with the fact that these two products are not powerful and do not consume much electricity.

The Medify MA-15 uses a 25W motor, while the Blueair 411 uses a 10W motor. Although Blueair uses a weaker motor, the difference in power consumption is not huge.

Product Wattage Range (W)
Medify Air MA-15 0.9 – 23.7W
Blue Pure 411 0.3 – 7.6 W

If you leave Medify running at third speed, 24 hours a day for a month, it will cost you about $ 2, while Blueair will cost you less than $ 1 in the same conditions. When it comes to the price of replacement filters, again, Blueair is much cheaper. In addition to more affordable filters, they also need to be changed less often.

Final Conclusion: Which is the Winner?

This was one fascinating comparison in which the Blueair 411 and Medify Air MA-15 were measured. Although Medify is designed for larger rooms, it also has more advanced features. In my opinion, a better choice to buy would be the Blueair 411 air purifier.

If you read the comparison carefully, you might have been able to guess who is the winner. The reasons the Blueair 411 is a better choice to buy are better performance, a much smaller power consumption, affordable price, and much more affordable replacement filters.

I think the reasons listed are enough to declare a winner. In any case, if you opt for Medify, you won’t go much wrong. You’ll get a device with good performance, slightly quieter than Blueair, and with many more advanced features.

    did you consider the reduced capacity of the Blueair 411 to deal with ultrafine particulars in your AQI analysis? will the m-15 not perform better overall when these smaller particles down to .3 microns are taken into account?


    • Milan Antonic

      The tests I do are specific, not the laboratory ones. In the tests presented in the comparison, I used the Temptop air quality meter.

      Additionally, I test almost every air purifier in different rooms such as the kitchen, a basement, a room where people smoke, etc. In that way, I get a subjective feeling of how an air purifier works in real-life conditions. Although my subjective feeling is not crucial in making a final decision, you wouldn’t believe me how different (performance-wise) are air purifiers from different brands.
