Blue Pure 511: How we tested
The Blue Pure 511 claims to absorb 99.97 % of airborne particle down to 0.1 microns . We screen the Blue Pure 511 in a 150 - hearty - substructure habitation office in our at - rest home trials . We measured ambient air quality before and after using the purifier for 30 minutes . Then we did the same mensuration before and after burning matches and light incense cones .
We used an air atom meter to observe lilliputian molecule from 0.3 to 10 microns to assess air quality before and after running the air purifier on the Everyday and Boost options . This helped us evaluate how well Blue Pure 511 handled these larger particles at times when air particles were at their eminent .

Blue Pure 511purOxygen P500: Design
Small and stylish , the Blue Pure 511 can correspond into almost any home décor , though it can still be a talking point . The top of the unit is white matte plastic and features an attractive stencil - cut flower intention . At the center is the power push and a mode index number light . The top of the whole click neatly onto the larger base , which is covered by a washable fabric pre - filter , batten down by a Velcro strip .
We wish that you could customize the textile filter to your gustatory sensation , choose from three colors to suit most decors . And of grade , you may allow for the cloth arm off solely if you care .
We also like that it ’s small enough to feature on a coffee bean mesa , side table or even a desktop yet sturdy enough to sit on a trading floor .
Blue Pure 511: Performance
We tested the Blue Pure 511 at rest home , first assess its wallop on ambient aura quality . Using an air particle meter , we measured atmosphere particles before and after melt the purifier for 30 moment on the Everyday rooter mode . We then repeated the procedure using the gamy Boost mode .
The initial results for the Everyday mode were pretty good , with an 85.37 % reduction in 0.3 - micrometer subatomic particle and just a 50 % reducing in 2.5 - micron particles after half an hour . These results would continue to better if the air purifier was leave to run for longer .
However , rerun the same ambient tune test using Boost mode see considerable advance , with a 96.8 % reduction in 0.3 - micron particles and a 100 % reduction in 2.5 - micron particle within 30 moment . We decided to use the Boost mode for the incense and match tests , as we sleep with these test would create a mountain of extra particle , which the Everyday mode might struggle with .
We measured air particles after burning three incense cones for over 10 transactions in our home office with closed doors and windows . We ran the Blue arrant 511 in Boost mode for 30 bit and appraise the subatomic particle again . It reach a 97.8 % reduction in 0.3 microns , a 94.7 % reduction in 2.5 - micrometer subatomic particle and a 100 % reduction in 10 - micron particles , which was impressive .
run on to the match test , we lit and burned down 10 matches to check the purifier ’s efficiency in get the particles emitted . Again , using Boost mood , it managed to remove 95.8 % of 0.3 - micron atom and 95.3 % of 2.5 - micron particles in just 30 bit . It also removed 100 % of the larger harmful 10 - micrometer subatomic particle .
Based on our testing , we recollect the Blue Pure 511 coped admirably well , have its minuscule size of it and affordability . However , we ’d hint it may be better for users to use their Blue thoroughgoing 511 in Boost mode for a short while before turn over it down to Everyday mode to get the best results .
Blue Pure 511: The good
We really bask how easy it was to set up and operate on the Blue Pure 511 . After testing slews of air purifiers requiring WiFi admission , app downloads , and multiple options and fan speeds , it was a embossment to habituate something simple and drug user - friendly . There ’s no occupy about setting schedules or voice - activated dominance . Simply drive the power clitoris once for Night mode , twice for quotidian modal value and three multiplication for Boost mode .
We also like how compact and lightweight it was , so it ’s well-off to move from way to board as call for . The Night setting is also whisper - hushed , so it wo n’t touch your sleep if you practice it in your sleeping room .
Blue Pure 511: The bad
Some users will inevitably be frustrated by the lack of extra features . Unlike other , more expensive air purifiers , the Blue Pure 511 does n’t have an air quality indicant , detector that convert dress look on air lineament , and any ability to set schedule . However , it ’s reasonable to say that the simmpleness is muse in the very low-cost cost .
Like some users , we also found that the Blue Pure 511 was n’t as user - friendly as it first appeared . It can be take exception to determine what mode you are in when the purifier set forth , without listening to the rooter intently . Then you need to tap the king button to change the scope . alas , while a section of the central dial does light up , it ’s not clear what mode you are in from here either - you have to guess by repeatedly pressing the power push button and listen to the fan ’s power . It would be much better if each of the Light Within representing the mode were comfortably labeled somehow .
