Blueair 211 vs 121

Blue air 211:

The Blue Pure 211 is the Blueair Blue family’s flagship at the moment. For the Classic, it is the Blueair Classic 680i and for the Sense, you can have the Blueair Sense+. This device is a slightly different proposition. Though it’s quite big, the Blue Pure 211 is still one of the best compact and simple air purifiers in the world. Let’s not waste your time anymore and get ready for the blue air purifier. Blueair is a Swedish brand that designs air purifiers and other home solutions with smarter and reactive features. Made from 100% recyclable materials, these products stay on top of your indoor air quality. Not only do they track the changes in air quality. But they can adjust certain settings such as fan speed to ensure you have a healthy living environment. One of the best air purifiers is the Blueair Blue Pure 211.

Design and size:

Being a flagship of this family, the Blue Pure 211 is actually the first of its kind. Apparently, the Blue Pure 211 is just a super-sized Blue Pure 211, at least that’s exactly what it looks like. There’s more to it than that when you dig a little deeper, though. The big differentiator is 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 211not a very different proposition to its little sibling.

Blueair is rarely bold with its colour choices for the Blue family, and with this Blue, Pure 211 things are still remaining. You will choose from a variety of colours for your back-to-front fabric pre-filter: 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 colour.

 

Filters:

1. FilterPre-filter

The fabric pre-filter of Blue Pure 211 is outside the air purifier and can catch large particles. This pre-filter is washable or vacuumable.

2.  Particle-filter

Instead of using a True HEPA filter, Blue Pure 211 uses a polypropylene fibers filter to help capture 99% of all allergens like dust, dust mites, pet dander, pollen and fungi (HEPA technology).

3. Activated carbon filter 

The Activated Carbon filter is added inside the Particle filter and effective against smoke, odors, gases and VOCs. Without a True HEPA filter is a disadvantage to Blue Pure 211, especially when the market becomes increasingly saturated with the certified HEPA filter. However, the Blue Pure 211 is still powerful with a unique Particle Filter with HEPASilent technology, to combine both mechanical and electrostatic filtration at one.

Room coverage:

This unit is ideal for large rooms, offices, or large spaces up to 540 sq. Independently tested. Performance Certified by Aham to filter room air 5x an hour in medium to large bedrooms, living rooms and spaces up to 540 square feet.

Sound:

HEPASilent technology helps reduce the noise level significantly from all Blueair air purifiers. That’s why Blueair can achieve such a noise level even with a huge and powerful fan. In the case of Blue Pure 211, with a more powerful fan than even the Honeywell HPA300, the result of its noise level is truly impressive.

Pros:

• Fantastic performance
• Well built for the price
• Slightly quiet
• Low-cost filter replacement
• 46 sq ft large pleated fibrous particle filter
• High airflow rate, suitable for remove
• Allergens faster
• Multicolour fabric pre-filter option
• One-button minimalist design
• Low energy consumption, Energy Star certified

Cons:

• Still no air sensor
• No timer
• The particle filter is not HEPA-grade
• Not suitable for odor removal
• Fewer features, no timer function, no air quality sensor

Blue Air 121:

The Blueair Pure 121 Auto has impressed me both in styling and performance. In its first 48 hours of use, I’ve seen and felt the impact it has made on the air I breathe. With the pandemic still lingering, I’ve had a lot of time to transform my 500-square-foot garage into another inhabitable spot in our home. A man cave, if you will. Here is where I perform my work-from-home duties, watch TV and play video games. The trouble with the garage is it’s not quite as insulated nor sealed as the rest of the home, so particulate matter and dust roam freely. I notice daily because my keyboard is covered in it by the time I

begin my day. The 121 Auto changed that overnight! On the first night, I ran a full blast to get the air in a nominal state before switching to auto. Within a half hour, I can already smell the difference; the air was removed of garage smells, and it was very pleasant to inhale the fresh air. I couldn’t believe it. Waking up to see that the keyboard had much less dust on it was a happy sight to see. The Blueair Blue Pure 121 Plus has a no-frills, streamlined design that’s easy to use. It has a 360-degree air intake to pull in airborne irritants from all corners of a room. One button controls the fan speed, indicates when the filter needs replacing, and powers the unit on and off. Designed for use in large spaces, the Blueair Blue Pure 121 Plus is built with a three-filtration system to pull every possible particle out of the air. The Blueair Blue Pure 121 Plus is moderately expensive but worth the investment. Designed for use in large rooms, it is probably best suited for your living room area. It may also be helpful near the kitchen since it also helps pull odors out of the air.

Design and size:

The Blue Pure 121 ushered in a new design direction for the company and its DNA runs strong within the Blue Pure 121. Thanks to a slightly shorter size, with only 20 inches in height (the Blue Pure 121 is 28 inches), this Blue Pure 121’s footprint is fractionally smaller and it is lighter but beyond that, changes appear slight. This air purifier uses a similar design concept like most of the compact air purifiers at the moment, with a 360 Degree of air intake to maximize the efficiency of the fan power. The air outlet will be found on top of the Blue Pure 121

Filters:

1.  Pre-filter

The fabric pre-filter of Blue Pure 121 is outside the air purifier and can catch large particles. This pre-filter is washable or vacuumable.

2.  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).

3.  Activated Carbon Filter

The Activated Carbon filter is added inside the Particle filter and is effective against smoke, odors, gases and VOCs. Like any other air purifier in the 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 a True HEPA filter in terms of air filtration performance.

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 the $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 highlights 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.

Sound:

This air purifier still holds a common noise level from 31 to 56 decibels (DB) like its little brother pure air purifier211. What you gain with an unrivalled fan power only in exchange for an acceptable noise level. At the lowest setting, the noise level of 31

decibels is only half the noise level of the 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 white noise and can help them sleep easily. We highly recommended to use it in large public places like your offices or dorms.

Power consumption:

As one member of the Blue family, Blue Pure 121 needs to reserve 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, which also gains the Energy Star rating. 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.

Pros:

• Pre-filter comes in five colours, washable fabric
• Minimalist one-button design, glossy finish
• The Built-in LED indicator, automatically dims after 7 seconds
• Energy-efficient, AHAM verified, CARB approve
• Super easy function
• Good results on air quality and fast
• One of the highest CADR ratings on the market

Cons:

• ESP filtration produces ozone, which is not suitable for asthmatic persons
• Filter replacement cost is a bit high
• Some people have noticed a strong smell in the
• Early days
• It has no automatic features.

FAQS:

Without pre-filter, can I use the blue air purifiers?

The simple answer is yes; without adding the prefilter, you can still run the blue air purifier. Though, you can put a lot of strain on the main filter. This is because the purpose of the pre-filter is to stop large particles that are getting clogging the main filter.

Can I clean the blue air prefilter?

Yes, thereafter, hang it for dry and wash it from the machine.

Frequently, how should I wash the pre-filter?

Every 2 to 3 months, you should wash the pre-filter. But it depends on where it is, and it has a kind of air filter. Dirtier pre-filters might find a scenario where it is quicker than anticipated.in such type of scenario, Before recommended 2-3 months, you should go ahead for wash it.

Do air quality sensors available in these types of models?

No, on their devices, the blue family of blue air purifiers has no quality sensors in an air purifier. But if you want to keep your air clean, run to your devices to keep it running on medium or low.

Conclusion:

In my opinion, both air purifiers are best in their prices. Both machines are certified and tested and have a delivery rate clean by AHAM value. It has a similar power consumption level. And have a similar noise level. Both purifiers are good and solve their objectives. At the given price, it really should have such type of features as sleep mode, timer, auto mode, and air quality indicator lights. It’s a good-looking brand air purifier,

SO YOU CAN BUY IT NOW.
