The new Cannon kicks butt (scientific definition of kicking butt<\/a>), but it\u2019s noisier than the Original DIY. How noisy is it? As is my habit, I wanted to answer this question scientifically.<\/p>\n

So I bought a decibel meter:<\/p>\n

\"1\"<\/p>\n

And I tested the Cannon, Original DIY, Blue Air 203\/270E, and IQ Health Pro Plus on their highest settings from 1.95 meters away. That’s the distance between my pillow and where I put the purifiers. Here are the results:<\/p>\n

\"2\"<\/p>\n

The cannon is noisier than I\u2019d like, but it\u2019s similar to the Blue Air on the high setting. To give you an idea of how loud that is, this decibel chart<\/a> says that\u2019s between \u201cconversation at home\u201d and \u201cconversation in restaurant.\u201d<\/p>\n

It\u2019s louder than I\u2019d like, but fortunately I\u2019ve found that the Cannon is still very effective on the lower settings:<\/p>\n

\"3\"<\/p>\n

So I recommend running the cannon on a lower setting if you find it noisy.<\/p>\n

Conclusions:\u00a0<\/strong><\/p>\n

    \n
  1. Cannon-owners can use the lower settings without sacrificing much performance.<\/li>\n
  2. For people who are particularly sensitive to noise, the Original may be a better choice.<\/li>\n
  3. For people who are VERY sensitive to noise, the\u00a0Philips AC4072<\/a>\u00a0is expensive (2,700 RMB), but it\u2019s quite quiet on the low setting.<\/li>\n<\/ol>\n

    As always, I\u2019m posting the data and methods below for fellow nerds.<\/p>\n

    <\/p>\n

    I\u2019m posting the raw data here for the medium and low settings. The raw data for the tests on the high setting\u00a0are here<\/a>. All of the methods are identical to my\u00a0previous tests<\/a>\u00a0and are described in (excruciating) detail there.<\/p>\n

    The Cannon and HEPA used in these tests are identical to the kits we are shipping from\u00a0Smart Air<\/a>.\"4\"<\/p>\n
