Other Blueair’s Air Purifier Reviews:
Blue Pure 121 Price
The Blue Pure 121 is the flagship from the Blue family of Blueair. That means it has a bigger size, a more powerful fan, and a higher price.
And it’s that final part that’s the Blue Pure 121’s only major issue. It comes with a hefty price tag of $349, putting it in direct competition with some very strong alternatives. In another family of Blueair, the Blueair Classic 205 provides the same powerful filtration technology with some tricky smart features. Though the Classic 205 doesn’t have much power for the price, in a modern day, using a Smart air purifier is always more likely than a classic one.
Other competitors with strong foundation in air purification industry are GermGuardian AC9200WCA, Rabbit Air BioGS 2.0 and Levoit LV-H133. They both offer lots of unique features and a little bit easy-going price to be settled in your home. But for the design, the top dog that has the most potential to compete with the strong power of Blue Pure 121 is Levoit LV-H134.
However, as a symbol of the most easy-of-use air purifier, Blue Pure 121 is still the Amazon’s Choice for many years, and will continue to keep this title for long.

Blue Pure 121 Design and Size
Being a flagship of this family, the Blue Pure 121 is actually the first of its kind. Apparently, the Blue Pure 121 is just a super-sized Blue Pure 211, at least that’s exactly what it looks like. There’s a more to it than that when you dig a little deeper, though. The big differentiator is that the huge 28-inch in height (the Blue Pure 211 is only 20 inches). Apart from that, it is still 13 inches in both width and depth, making Blue Pure 121 not a very different proposition to it’s little sibling.
This is also an air purifier that displays all Blue family’s key trademarks. That means you are looking at an unique one-button control air purifier in the world. So much ease of use in one powerful device, right?
Blueair is rarely bold with its color choices for Blue family, and with this Blue Pure 121 things are still remaining. You will choose from a variety of colors for your back-to-front fabric pre-filter: from the Buff Yellow, Crystal Pink, Diva Blue, Dark Shadow and Lunar Rock. Our testing unit in this review is a Dark Shadow edition, which is a truly mysterious black color.
With that huge spandex fabric pre-filter, you can imagine a huge 360 Degree intake air grill under it. This design concept is the most proper to utilize the efficiency of Blue Pure 121’s fan power. The air flow will direct the clean air to the top of this air purifier. A simple and powerful air flow system, which is mimicked by other competitors like the flagship of Levoit brand – Levoit LV-H133. This Levoit air purifier is also considered as the closest competitors to the Blue Pure 211.
The Blue Pure 121 is well balanced and light enough too at just 18 lbs. You’ll happily move it around your home without much effort like other Blueair air purifiers, for example Blueair Classic 405 (33 lbs) or Blueair Pro M (24 lbs). The Levoit LV-H133 is also heavier with a weight of 20.9 lbs.

Blue Pure 121 Filters
As the most important criteria to decide one air purifier’s power, we check the performance rating due to the materials of the filters and the air filter types are used. As the flagship of one family in the well-known Blueair brand, Blue Pure 121 delivers a powerful 3-stage air cleaning system as below.
- Pre-filter – The fabric pre-filter of Blue Pure 121 is outside the air purifier and can catch the large particles. This pre-filter is washable or vacuumable.
- Particle filter – Instead of using a True HEPA filter, Blue Pure 121 uses a polypropylene fibers filter to help capture 99% of all allergens like dust, dust mites, pet dander, pollen and fungi (HEPA technology).
- Activated Carbon Filter – The Activated Carbon filter is added inside the Particle filter and effective against smoke, odors, gases and VOCs.
Like any other air purifiers in Blue family, Blue Pure 121 doesn’t use a True HEPA filter. Instead, to remove allergens, pollen, mold spores and other irritants, Blue Pure 121 makes use of its Particle Filter and HEPASilent technology, to combine both mechanical and electrostatic filtration. With a simple air filtration like that, Blue Pure 121 can even match the Levoit LV-H133 with True HEPA filter in terms of air filtration performance.
The keywords using in this Blue Pure 121 is “simple”, and “strong”. The Blue Pure 121 operates at a pace no air purifier could do. To test the performance and compare with others, I put the new Levoit LV-H134, Sharp FP-A80UW and GermGuardian AC9400W in one room of 400 square feet. After one hour of running, the final result is interesting. Blue Pure 121 was the best performer with high efficiency of 99.92% of removing any particles down to 0.3 microns. The Sharp FP-A80UW only secured the runner-up with 99.91%, while both the GermGuardian AC9400W and Levoit LV-H134 were in third place with 99.9%. That’s how strong this Blue Pure 121 is.
Most importantly, the polypropylene fibers from this air purifier are free of chemicals and naturally anti-bacterial. Also, this Particle filter is 100% recyclable.
Only one downside, the filter cost of Blue Pure 121 is $109, which is higher than most of proper True HEPA filters from other brands. A filter of Coway AP-1512HH is about $45, or a pack of 3 filters for Honeywell HPA300 costs only $68. These above air purifiers are all staying in the list of best air purifiers 2019. You also need to replace this filter after 6 months of use.

Blue Pure 121 Room Coverage
As the most powerful air purifier in one family of Blueair, Blue Pure 121 can also cover the largest space of polluted air. For our testing unit, the room coverage of Blue Pure 121 is up to 620 square feet. This room coverage is no doubt the largest among air purifiers in $350 price range. The Rabbit Air BioGS 2.0 can cover 625 square feet, but with a more expensive cost. Others like Winix WAC9500 and Levoit LV-H133 can’t cover more than 550 square feet.
The ACH of Blue Pure 121 is 5X. Blueair always highlight their air purifiers’ power through an impeccable fan. 5X is among the highest ACH rating, which results in a frequency of 5 times air changes per hour.
The CADR of Blue Pure 121 is 400 Dust/ 400 Smoke/ 400 Pollen (cfm). This CADR rating is truly impressive, which brings the fan power of this $350 air purifier to equal with other high-range machines, like Austin Air HealthMate Plus (with 400 cfm CADR) or even Oransi Erik 650A (with 413 cfm CADR).

Blue Pure 121 Sound
Even with a stable and helpful technology like HEPASilent to reduce the noise level, Blue Pure 121 is still an air purifier for large room with a huge fan. Generally, an air purifier with such fan power can’t be quiet, especially at the highest setting.
However, this air purifier still hold a common noise level from 31 to 56 decibels (db) like its little brother – the Blue Pure 211. What you gain with an unrivaled fan power only exchange for an acceptable noise level. At the lowest setting, the noise level of 31 decibels is only half the noise level of library (which is truly quiet). Even if you try to run this Blue Pure 121 at the highest setting, the noise level is just like normal conservation at home. For some people, this is just the white noise and can help them sleep easily.
We highly recommended to use it in a large public places like your offices or dorms.

Blue Pure 121 Power Consumption
One of our most FAQs is “Do air purifiers use a lot of energy?” An air purifier is designed to run for a long time to be efficient. Therefore power consumption is always one important criteria when you decide to buy one air purifier.
As one member of Blue family, Blue Pure 121 needs to reserve the energy better than other large room air purifiers, which are mostly expected to consume lots of energy. We are happy to have a Blue Pure 121 with only 30 to 61 watts for energy consumption. With that much power, the Blue Pure 121 is actually as energy-saving as the previous Blue Pure 211. However, in this price range, the most energy-saving air purifier is still the Rabbit Air BioGS 2.0, which no other can beat in this field.
An investment in a Blue Pure 121 results in about $11 to $21 annually.

Blue Pure 121 Additional Features
One thing never change in Blue family of Blueair brand, there is no additional features for this one-button air purifier. You can’t expect any additional features in this Blue Pure 121, and with that said, no air sensor or timer. That’s how the Blueair calls “simple”.
To compensate for a powerful fan and high-quality materials, it’s inevitable to lose some smart features. If you are looking for a smart air purifier, you need to cut off some fan power, like in this Winix WAC9500. Or a Levoit LV-H133 with only half of CADR rating, but with more useful features.
For a Blueair air purifier with both high fan power and lots of useful features, you need to pay more than $500 to buy this Blueair Classic 405, a Today’s Parent recommendation for high-quality air purifier.
