Blueair Pro M Hepasilent Air Purifier

Does an amazing job keeping parts per million down to below 2.5 µm

I am highly interested in the proper filtration of air and water, as these are of the most important elements for our physical existence, yet we can liver much longer without water than without air. We take in a new breath of air every few seconds, which then gets filtered out by the lungs.First I will say that most air filter companies out there don't really provide much scientific detail or testing on the way their system works, beyond just basic description of the stages and all are pretty much the same thing in a different wrapper, not much research has gone into proper air flow, powerful silent motors, scientifically correct placement and amount/quality of filtration media, proper insulation so no dirty air channels through holes and cracks in the frame, etc.After much in-depth research, I ended up with a choice between AirIQ and Blueair. After contacting AirIQ with some scientific questions, first impression was that their support reps are overworked and rush through your questions, second, AirIQ mails their filter media cartridges exposed to air, which is not good. It's a fact that carbon and other filtration media will readily absorb contaminants from the atmosphere unless properly sealed before it gets to you, thereby, shortening the capacity/life of the filter media prematurely. Furthermore, their technical department had no idea how to answer my questions, and did not return phone calls. I was totally turned off by their energy and lack of knowledge.Now, after calling Blueair support team, it was like a breath of fresh air. The were patient, genuine, explained their system in detail, and pointed me to a scientific, yet easy to understand video on their website, which is what played the deciding factor in choosing them over AirIQ:[...]I also used a laser particle counter from Dylos which measures down to 0.5 microns (beach sand is about 100 microns), which is quite accurate and nearly real-time analysis of particle much lower than the 2.5pm standard. Upon measuring the air in my bedroom, I found there were over 1000 particles smaller than 2.5pm, I closed the door and window and turned on this system on full speed. Within 10 minutes, the ultra-fine particle count went down to 200 and within 30 minutes it was in the 70s. Keep in mind, these are particles as small as bacteria and cannot be seen by the naked eye! This filter really works at removing ultrafine particles quickly!Also, in addition to their HepaSilent technology, their use special coconut shell activated carbon (the best carbon for absorbing volatile chemicals) which is further enhanced by being impregnated with magnesium and copper in order to be much more effective at breaking down difficult chemicals. Most other filter's I've seen just use regular activated carbon, and a very small amount of it.Looking back, considering how much I have spent in the past on cheap and poorly thought-out filters, I should have just bought this, but then again, I had to go through that learning curve with inferior units to recognize the value of this product. They also offer a decent warranty of 5 years if you register your product with them. Would have been better if the unit was actually Made in Sweden instead of China, but nevertheless, the build quality and materials look and feel good, the warranty is reassuring, and the performance was verified by my particle counter.Overall, very pleased with product quality, effectiveness, design and customer service. Top grade company with top grade products!BlueAir, I Hope you continue in this direction, stay true to real scientific principles, and don't become a publicly traded company (don't sell out to investors for greater profits), stay true to your customers and you will be in business for generations!

Fantastic product. Can’t say enough wonderful product

Really powerful and quiet when on low. Needed to buy an additional module separately to be able to use the auto function

Definitely as described. Purifier is very quiet however it is a lot smaller to competitors out there and does not cycle air as fast. I keep this as my bedroom air purifier as it is small and quiet
