Blueair DustMagnet 5210i Price

The Blueair DustMagnet 5210i is a dainty yet smart delight. This air purifier is built for those who have been dreaming of owning a Blueair console air purifier but aren’t ready to spend money for the HealthProtect series. And Blueair has done an exceedingly good job at making that a reality, still being certified by the AHAM, CARB, Energy Star and Intertek.

It has a more premium version called Blueair DustMagnet 5240i, and we’re running both to compare the performance. Spoiler alert: you should buy the Blueair DustMagnet 5210i for only $319, $40 less with the same performance as the DustMagnet 5240i.

It isn’t perfect, as its fan power is a bit below the competition like the Coway AP-1512HHS, Levoit Core 600S and its own brothers in different line: Blue Pure 311 Auto and Blue Pure 211 Auto. But if you can put this negative aside, you will love the Blueair DustMagnet 5210i and even pay more for its premium version, because it has great smart features and extremely economical for long-term running.

If you can stretch budget more, the options of Blueair DustMagnet 5410i and DustMagnet 5440i are much better for larger rooms, but at the extra of $80.

Blueair DustMagnet 5210i Design and Size

Blueair DustMagnet 5210i is a very special air purifier you can find on the market, along with its brothers in family. It doesn’t have the casters like other common Blueair air purifiers you’ve seen, but it’s a welcome alternative for those who want a smaller air purifier, and who’ve looked on in dismay as Blueair has released big air purifiers with high cost.

It essentially the basic design concept of the whole DustMagnet family, an air purifier with a small “table” on top, so you can put anything on it for convenient. The design is interesting, but after months of running the air purifier, the table is a hidden place for dust, just like its name DustMagnet implies.

With dimensions of 20.5 x 8.6 x 8.6 inches, it’s smaller than most other Blueair air purifiers. It’s also light, without feeling too light – at 10 lbs, you can trust it can stand on its own toes. The legs is also a good design for the Blueair DustMagnet 5210i, as it helps its fan power to maximize the volume of air into the unit, and reduces the dust settled in the bottom. Bravo design, Blueair.

The Blueair DustMagnet 5210i is the standard version of the series, with white color. I also find the white color is suitable for any devices that sucks dust. If you prefer a more premium texture, you should look for the DustMagnet 5240i or DustMagnet 5440i.

Blueair DustMagnet 5210i will run the same bottom-to-top air flow system concept, but the air outlets are not only from top, but also from both sides. That makes me remember of the perfect design of the original Blueair Classic 605, and it is also implemented in the Blueair HealthProtect 7770i. As I must say, even the budget Blueair air purifier feels premium.

The control panel is hidden under the table, and with as little buttons as it should be, because the Blueair DustMagnet 5210i is a true smart air purifier. You will control it either with your smartphone or Alexa voice control.

Blueair DustMagnet 5210i Filters

As the most important criteria to decide the performance of one air purifier, we always look at the quality and material of the air filters, as well as the number of air filter types in the testing device. Blueair DustMagnet 5210i features the signature HEPASilent technology from the first Blueair device.

  1. Pre-filter – For best performance, you’re required to clean the pre-filter weekly. It can trap large objects of pollutants, to prolong the life time of the Combo Filter.
  2. Combo Filter – The combination of True HEPA filter and Activated Carbon filter, the Blueair DustMagnet 5210i removes light household odors, chemicals, and gases, as well as 99.97% of airborne particles, like pollen, dust, viruses…

Though the company doesn’t say much, I’m certain this is still the core of HEPASilent technology, which combines both electrostatic charging and mechanical filtration to improve the performance of the HEPA filter. However, it seems the Blueair DustMagnet 5210i is just a simple “dust-magnet” air purifier with a light carbon cloth attached inside.

Still, this is the certified air purifier by the Association of Home Appliance Manufacturers (AHAM) for its great performance. Blueair DustMagnet 5210i also doesn’t emit ozone, certified by both the CARB and Intertek.

The last but not least, all of Blueair air filters are naturally anti-bacterial and 100% recyclable. It is free of chemicals and binders.

Blueair DustMagnet 5210i is a bit behind the competition, but it certainly doesn’t lack power. It’s suitably powerful as it can clean 99.7% of all particles down to 0.3 microns in our test of 200 square feet, for 1 hour. Well, that’s a bit behind the Medify MA-35 and Oransi Max, but not by much.

However, the best thing about the combo filter of the Blueair DustMagnet 5210i and DustMagnet 5240i is that it is only $44 and can last for 1 year. That’s why its annual cost ranking is great, in fact, it is a lot better than its brother Blue Pure 211 Auto.

Blueair DustMagnet 5210i Room Coverage

Blueair DustMagnet 5210i is completely certified by the AHAM, so the manufacturer doesn’t need to suggest room coverage for this air purifier. Both 5200 models are certified to clean up to 212 square feet. While that may not match a lot of other manufacturers on paper, we found that any air purifiers complied for AHAM certification is better in terms of quality. That’s why we consider it as an increase in performance ranking.

The ACH of Blueair DustMagnet 5210i is 5X. This ACH rating is certified by AHAM too, so you can enjoy clean air every 12 minutes.

The CADR of Blueair DustMagnet 5210i is 133 Dust/ 137 Smoke/ 140 Pollen (cfm). Yes, we know it is even lower than the Classic 205 that you loved in the past, but our test indicated that the performance of Blueair DustMagnet 5210i is still decent for the competition.

Blueair DustMagnet 5210i Sound

Blueair DustMagnet 5210i, while not being as powerful as its brothers, is really quiet. It can trim the noise level to only 23 decibels (db) on lowest fan speed, and that’s just like the sound of rustling leaves. That’s the power of HEPASilent technology.

Even on highest fan power, the noise level is only 47 decibels. The fact is this Blueair DustMagnet 5210i could be the most silent air purifier, even better on highest fan power versus the Blue Pure 311 Auto, the best air purifier for bedroom.

Blueair DustMagnet 5210i Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?” An air purifier is meant to run for a long time to be efficient, that’s why many air purifier brands consider the energy-saving standard, mostly in the rate of Energy Star, is one important selling point.

The Blueair DustMagnet 5210i is an Energy Star air purifier, and it shows off its incredible CADR rating per watts, as its rated power is only 4 to 22 watts. Yes, this is such an incredible air purifier with performance per power, and it is even better than its HealthProtect flagship brother.

If you use the Blueair DustMagnet 5210i for 8 hours per day, you only need to pay up to $8 annually. I believe this is the most economical air purifier in terms of both energy saving and low-cost filter replacement.

Blueair DustMagnet 5210i Additional Features

Blueair DustMagnet 5210i is a top pick for its combination of performance and great smart features. The Blueair DustMagnet 5210i ports nearly everything good from its top-of-the-line brothers, especially the Wi-Fi enabled feature. This air purifier is available to control anywhere with your smartphone app. It is also compatible with voice commands of Alexa and Google Assistant.

It obviously has a dust sensor, because the air purifier is a dust magnet itself. The Smart Sensor can activate Auto Mode, which adjusts to changing fan speed when pollution levels rise in your indoor environment and return to a slower speed once the air is clean. There is an advanced sensor to automatically turn on or off the device whenever you come and go.

The one thing special about the DustMagnet series is its Auto Start feature, this means that the unit will automatically restart at the set speed if a power failure occurs, the unit is unplugged or a power switch timer is used.

Night mode is available as a great material for your bedroom. When in night mode, your DustMagnet air purifier disables features you don’t need while sleeping. This includes the Air Quality Indicator LED light and adjusting to a whisper-quiet low speed.

Finally, you don’t need to track the filter life, because the DustMagnet 5210i will alert you on time.
