Blue Pure 211+ colours


Winner of the prestigious 2014 Envisioneering Innovation & Design Award at IFA Berlin and Consumer Report's top air purifier choice for 2017, Blueair’s Blue Pure 211 air purifier has been improved, with the new Blue 211+ model now able to handle light chemical and gases. This affordable powerhouse offers effective air cleaning in large spaces, while still being ultra-quiet, energy-efficient and style-conscious. The Blue Pure 211+ boasts the cleaning power and room coverage of Blueair's more expensive models for less than $350! If you’ve been looking for high-end air purification at a reasonable price, this is the air purifier you’ve been waiting for!

Unlike other Blueair air purifiers, the Blue Pure 211+ features a washable fabric pre-filter designed to capture larger particles before they have a chance to enter the main filter. This prolongs the life of the main filter, allowing up to one year of use between filter changes. The pre-filter also doubles as a design element so that you can customize the air purifier’s look to your décor. The Blue Pure 211+ comes supplied with the “dark shadow” (dark grey) and "diva blue" pre-filters, but trendy colours such as crystal pink, buff yellow and lunar rock (light grey) can be ordered separately.

The Blue Pure 211+ air purifier offers a number of other stand-out features that make it unique in Blueair’s product line. At the heart of the Blue Pure 211+ is a fan with four over-sized 12” blades, designed to deliver more clean air faster and more quietly than air purifiers that are equipped with the standard one or two-blade fan. In addition, a 360 degree air intake makes the Blue Pure 211+ efficient no matter where you place it in the room, while the clean air outlet located on the top of the unit allows for unobstructed air circulation. A one-touch button on the front of the Blue Pure 211+ controls all air purifier functions (e.g., on/off, speed), making it a breeze to use, while the durable plastic and steel mesh housing make it extremely lightweight so it can easily be moved.

Blue Pure 211+ features

The Blue Pure 211+ air purifier features Blueair’s tried and true HEPASilent technology, allowing it to outperform ordinary medical-grade HEPA filters by combining mechanical filtration and electrostatic principles. As contaminated air is drawn silently into the Blue Pure 211+, all but the finest of particles are captured by a remarkable 46 sq. ft. of filtration media. The Blueair Blue Pure 211+ uses an advanced gradient media filter that is comprised of millions of interwoven ultra-thin fibres of different sizes and layers. This progressive filter design permanently captures airborne particles including pollen, dust, mould spores, pet dander, smoke particulates, combustion particles, printer/photocopier emissions, bacteria and other fine particulate matter.

The Blueair Pure 211’s internal ionizer than imparts a negative charge to any remaining ultra-fine particles in the air, ensuring that they adhere effortlessly to the positively-charged filter material on their next pass through the air purifier. This unique design allows the Blueair Blue Pure 211+ air purifier to capture an outstanding 99.97% of particles down to 0.1 microns, i.e., 3 times smaller than the particles trapped by traditional HEPA filters.

Putting the "Plus" in the Blue Pure 211+ is an activated carbon mesh filter for light chemical, gas and odour control. This has been incorporated into the main filter, so there is only one filter to change! Although not as effective as the woven activated carbon cloth media found in Blueair's Classic DualProtection filters, or the pounds granular activated carbon in Blueair's Pro GO SmokeStop filters, if you are only dealing with low-level ambient gaseous pollutants, then the Blue Pure 211's Particle+Carbon Combo filter will do the job.

Designed to be completely non-intrusive, the Blue Pure 211+ offers whisper-silent operation on low speed that will please even the most sound-sensitive people. Blueair even took the blue diode operating light on the unit into consideration, designing it to dim to a soft glow so that your sleep is not disturbed.

Energy Star-certified, the Blueair Pure 211+ is 40% more energy-efficient than most other air purifiers on the market, costing only pennies a day to operate for minimal impact on your electrical bills. And like all Blueair air purifiers, the Blue Pure 211+ releases absolutely no ozone or ozone by-products into the air, a must for individuals who are concerned about their respiratory health.

To maintain peak air cleaning performance the main filter in your Blueair Pure 211+ should be replaced every 6 to 12 months. When the indicator light on the one touch button turns red, it’s time to change the filter (with a yellow light giving you advanced warning). A periodic inspection of the filter should also be conducted to ensure that the airflow is not being impeded by a clogged filter in dustier environments. Changing the filter on the Blue Pure 211+ is simplicity itself: click the buttons on the side of the unit to release the top housing from the section with the filter in it, remove and discard the used filter, unfold the new filter and fit it inside the lower housing, then replace the top until it locks with a "click" sound. The unit’s fabric pre-filter can simply be washed, as needed.

Blueair’s unique Blue Pure 211+ air purifier is the perfect choice for allergy sufferers and health-conscious individuals who want a powerful air cleaning solution for a modest budget. Its compact size and ultra-quiet operation make it perfect for bachelor apartments, large bedrooms and offices where noise-free operation is a must.

“I received my Blueair Blue Pure 211+ air purifier, and in a very short time I can already feel the improvement in air quality in my home. As someone who has suffered from asthma and allergies all my life, the fact that I now wake up clear-headed and breathing normally throughout the day makes me realize how life-changing this will be. I hadn't seen the Marketplace episode testing of the various brands when I purchased. Instead, I researched air purifiers and learned everything I could to determine the important features to consider, and thankfully came to the same result. Thank you for the prompt delivery and for providing such an outstanding quality product.”
Carol C., Toronto ON

”My Blue Pure 211+ air purifier arrived this morning. I live in a 1000 sq ft Condo with a Magic Pac PVAC heating/cooling system. For unknown reasons, I have developed severe allergies that are currently being assessed. I am usually unable to see clearly or hear normally. My immunologist recommended purchasing the Blue Pure 211+ unit. Since plugging it in this morning, my normally swollen eyes and ears have cleared and my breathing has greatly improved. I do have to use antihistamines, but the difference in my ability to see, hear and breathe well is quite remarkable. I highly recommend the Blueair 211+. I will likely invest in a second and perhaps third unit for bedrooms. Robert from Modern Alchemy responded to my email enquiries quickly and in a highly professional manner. Thank you so much for excellent service and product. Modern Alchemy and Blueair - an awesome combination!”
K Marcino, Winnipeg, MB

“Thanks for the quick shipping on the Blueair Blue Pure 211+. It's already making a difference in our house. My pet allergies have noticeably fewer symptoms in just a few days. Pretty amazing! Please sign me up for the filter reminder program. I suspect this thing will be running constantly from now on!”
Dave D., Toronto ON

“Thanks so much for the excellent prompt service and surprisingly quick delivery. I’m delighted with the Blueair 211+ which substantially improved the air quality in our basement within a few hours and has helped us to regain full use of this space. It’s quiet operation means that I can run it continuously while conducting online meetings in my office.”
Paul H., Ottawa, ON

“I recently purchased two Blue Pure 211+ air purifiers and a Venta LW45 humidifier from you. I have set up both products and would comment that they are quiet, well-built and seem to be effective so far. Although it’s too early to comment completely on effectiveness, after two nights of sleeping in a room with both the Blueair and Venta units operating, I would say that my seasonal rhinitis shows signs of improvement, and therefore both breathing and sleep quality are improved. I will also say that I was pleased to find your business online. Your prices were very fair, and better than Amazon, you were there to answer the phone! Thank you for your emails along the way and follow-up throughout the process.”
R. Fowler, Mississauga, ON

“I recently purchased a Blue Pure 211+ air purifier from Modern Alchemy Air Purifiers. The service from Robert at Modern Alchemy was excellent. He was extremely helpful and patient and I received the air cleaner 2 days after the order – amazing! I ordered the Blue Pure 211+ unit to help with allergies, and I have noted a significant difference with my allergy symptoms. It would not be a good choice if the buyer was wanting to reduce household gases, e.g., cooking smells – however I knew this when I made the purchase. The sound on low or medium does not disrupt sleep and the air purifier is light enough to move easily to different rooms when desired. I am very happy with this purchase and the difference it has made.”
Kate C., Guelph ON

“My Blueair Pure Blue 211+ air purifier works great! I sleep better, am up earlier in the morning and feel a lot more alert and energetic. My lungs feel more relaxed and less congested, and I tend to take deeper breaths. It has only been 5-6 days since I received the unit! The Oransi EJ120 also works amazingly! My mom and brother are really happy. My mom is breathing easier and sleeps better through the night. The air smells cleaner too. It was the best decision to purchase both units!”
Tina K., LaSalle, QC

“Just wanted to let you know that the Blueair Classic 505 and three Blueair 211+ units that I purchased from you are awesome!! I never thought I could live with a cat!!! She says thanks too.”
D.W., Shelburne, ON

“I am very pleased with my Blueair Blue Pure 211+ air purifier that I recently purchased. It is very quiet during operation in various rooms we have used it in. The customer service from Robert at Modern Alchemy was friendly and helpful. The air purifier was ordered Friday afternoon and delivered Monday morning!”
Karen H, Uxbridge ON

“We purchased the Blueair Blue Pure 211+ air purifier almost a week ago. The reason we bought the product is that my son (4 months old) sneezed a lot. Also, I realized that I sneezed and had itchy eyes after I gave birth. We stay at home most of the time so we needed something to clean the air asap. I was so surprised and happy that we received the Blue Pure 211+ within 2 business days. It has been almost a week since we started using the air purifier, and we are very satisfied with it. My itchy eyes completely stopped. We only sneeze once or twice a day and there are days where we don't sneeze at all. I strongly recommend the Blue Pure 211+ to people who have allergies or who have a baby.”
Fumika O., Toronto, ON

“We have set our two Blueair Blue Pure 211+ units on the medium fan speed. The airflow is strong and also quiet. They were a good purchase, and now we are thinking of getting a 411+ for our son.”
B. Chan, Concord, ON

“We purchased the Blue Pure 211+ air purifier in the second half of 2020, and was motivated to do so with the poor air quality related to US wildfires that affected southern BC. We chose the 211+ unit based on positive reviews on the Modern Alchemy website and Consumer Reports. The customer experience with Modern Alchemy was very positive, and Robert handles questions quickly and efficiently. The unit arrived in great shape. Build quality looks good and assembly was very quick. In operation, it is very quiet at low speed, but the noise ramps up as expected at higher speeds. Operation is simple and intuitive. Overall, based on my early experience, the Blue Pure 211+ seems to be a very good air purifier.”
John N, BC

“The Blue Pure 211+ air purifiers that I purchased are as described, and I can see and feel the difference using them. I am also very happy with Robert’s quick communication and willingness to help on the delivery when there were challenges. Would highly recommend Robert and Blueair.”
Tanya S., Surrey, BC

“We always prefer to shop at Canadian retailers. While shopping for an air purifier, we were pleased to come across the Canadian retailer "Modern Alchemy." We found their website easy to use, with great, reasonably priced air purifiers and availability of replacement filters. We purchased a Blue Pure 211+ air purifier and are very happy with its performance and ease of use. The air purifier looks good and is not noisy. Dealing with Modern Alchemy was a very pleasant experience.”
Peter G., Port Rowan, ON

** An Important Word on Air Flow Rates and Room Coverage for the Blue Pure 211+ Air Purifier:

Many retailers and manufacturers overstate maximum room coverage figures by calculating them with air flow rates measured without filters installed (i.e., fan output) or with too low a number of air exchanges per hour to properly clean the room. Modern Alchemy Air Purifiers believes in stating the actual delivered air flow rates for the air purifiers we sell, as well as realistic room coverage figures calculated at effective air cleaning levels. Accordingly, we recommend that the Blue Pure 211+ be used in rooms of up to 338 sq. ft. (for premium cleaning) or 675 sq. ft. (for general purpose filtration).

Note that air purifier performance should not be judged by air flow rates and room maximums alone. Many features that make an air purifier more effective at cleaning the air actually reduce the air flow rate. For example, higher grade HEPA filters, well-sealed filtration systems and large amounts of carbon all increase air resistance and reduce delivered air flow rates.
