Blue Pure 411+ colours


With the launch of the new Blue Pure 411+ by Blueair, there’s no longer any reason for those on a budget to resort to ineffectual big box and hardware store air purifiers! The new Blue Pure 411+ air purifier offers high-performance air cleaning, durability and a striking design for under $200!

The new Blue Pure 411+ air purifier is an upgraded version of Blueair’s older 411 model, with a more powerful fan providing better room coverage and a premium metal-mesh frame for added durability. This compact and affordable air purifier offers effective air cleaning in spaces up to 110 sq. ft. (for premium cleaning) or 225 sq. ft. (for general purpose use), while still being ultra-quiet and energy-efficient.

Featuring Blueair’s proprietary HEPASilent filtration technology, the Blue Pure 411+ air purifier is able to capture particles down to 0.1 microns at 99.97% effectiveness – that’s 3x smaller then a medical-grade HEPA filter can achieve! The Blue Pure 411+ not only captures traditional allergens such as dust, pollen, mold spores, pet dander and dust mite by-products, but 0.1 micron filtration enables it to trap smog and smoke particulates, combustion particles and airborne pathogens such as bacteria as well.

Although not engineered for heavy chemical, gas and odour adsorption, the Blue Pure 411+ air purifier does incorporate an activated carbon mesh material into the filter, allowing it to handle low levels of ambient gaseous pollutants. So although the Pure 411+ can filter out the harmful particulates found in smog, smoke and vehicle exhaust, those who want full protection from the toxic gases associated with these pollutants should invest in Blueair’s Classic line of air purifiers (equipped with optional DualProtection filters) instead.

The Blue Pure 411+ by Blueair features a washable fabric pre-filter designed for use in environments with high levels of dust, pet hair and other large particulates. The Blue Pure 411+ comes with a Dark Shadow (dark grey) pre-filter, but extra prefilters can be purchased in one of five contemporary colours to accent your décor. While using the pre-filter can prolong the useful life of the main filter in dusty environments, some may want to forego it for a cleaner metal-mesh look. For those who prefer to go “naked,” the premium metal frame has been treated with an anti-scratch coating for long life and sustained good looks.

With a 360 degree air intake pulling pollutants into the air purifier from all directions, the Blue Pure 411+ is efficient no matter where you place it in the room. After passing through the filters, ultra-clean air exits the air purifier from the clean air outlet located on the top of the 411+ unit, allowing for unobstructed air circulation and preventing short-cutting (i.e., just cleaned air being pulled right back into the machine).

The Blue Pure 411+ couldn’t be easier to use – a one-touch button on top of the 411+ unit controls all major air purifier functions (e.g., on/off, fan speed selection). A filter indicator light on the button will turn red when it’s time to change the filter, a quick and easy process that requires no tools, with a simple twist giving you access to the filter. Typically the filter in the Blue Pure 411+ will last for 6 to 12 months.

If you are sensitive to sound, you will be happy to know that the Blue Pure 411+ air purifier has met and exceeded the highest standards of Quiet Mark (an independent, international approval award programme). The ultra-quiet operation of the Blue Pure 411+ (only 17 dB on its low speed setting) means undisrupted rest for light sleepers and minimal noise for work environments. Speaking of sleep, Blueair designed the blue diode operating light on the unit to automatically dim to a soft glow so as not to disturb your slumber.

Like all of their award-winning air purifiers, Blueair’s Blue Pure 411+ is AHAM tested for true Clean Air Delivery Rates (CADR), certified by the California Air Resources Board (CARB) as ozone safe and US EPA approved as an Energy Star rated device. On high speed, the 411+ air purifier only consumes as much energy as an LED lightbulb (around 10 watts). Running it all day on low speed to continuously maintain your indoor air quality will only use 1.5 watts of power, making it easy on your wallet.

The Blue Pure 411+ air purifier offers high-quality air cleaning performance at an unbeatable price. The unit’s ultra-compact and sleek design makes it the perfect choice for use in small bedrooms, nurseries, dorms, small offices, cubicles, hotel rooms and RVs.

“I recently purchased a Blueair Blue Pure 411+ air purifier from Modern Alchemy. We are very impressed and pleased with this purchase. Within a very short period of time, we noticed an improved quality in the air in our room. We share our home with a dog. My husband has allergies. Since running the 411+ my husband is less congested, and the room is so much fresher. The 411+ is light, easy to move and comes equipped with three speeds. We are also very impressed with Modern Alchemy. Customer service is obviously a priority. Robert is very knowledgeable and listens well to customer’s needs and suggests an air purifier accordingly. He answers questions easily and is happy to give reasons for his recommendation. There is excellent phone and email communication available if further information or clarification is required. I highly recommend Modern Alchemy to others.”

“Just wanted you to know that my new Blue Pure 411+ air purifier arrived a couple days ago. It seems to be working very well and is so quiet on speed 3 that you aren’t even aware it is there, except for the air being cleaner of course. The 411+ has a much better design than the earlier model I had looked at, and it arrived just in time for another round of smoke from the California fires. Thank you for your assistance and advice over the last few years.”
Kathleen B, Comox BC

“We received our two Blueair Blue Pure 411+ air purifiers recently and have tested both. Thank you, they are awesome!”
J. Noble, Kelowna BC

“Thank you for your quick delivery of our Blue Pure 411+ air purifier. It replaced our 25 yrs plus BREATHEasy Hepa in our bedroom. It's great, quiet, easy to operate and just the right size. We've recommended it to our family and friends.”
Pierre G, Rockland, ON

** An Important Word on Air Flow Rates and Room Coverage for the Blue Pure 411+ 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 411+ be used in rooms of up to 110 sq. ft. (for premium cleaning) or 225 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.
