7 micron will filter smaller particles than 10 micron.
It is 7*100 microns.
0.1 micron = 10-7 metres or one ten millionths of a metre.
7 microns
Since 62 is a bigger number than 7, and you are measuring the same unit, 62 microns is bigger than 7 microns.
Because it's the same units used and 7 > 3. (ie 7 kilometres is farther to run than 3 kilometres)
In my opinion, EQ of magnitude 7 means , the Amplitude of vibration due to the EQ is 10 metres.( 107 microns). Those who agree with my answer , please confirm it.
Merv ratings are a more quantifiable way to measure the effectiveness of a filter to remove contaminants from the air stream. A filter with a MERV rating of 3 is a typical home furnace filter and is about 15% efficient at removing dust. A MERV 7 is one of the better residential furnace filters you can purchase and is about 25% efficient at removing dust. A MERV 12 filter is the top of the line filter for residential use and is about 70% efficient. There are multiple steps in between and there are steps above that are used in commercial applications. HEPA filters that you will see for residential use and in clean room applications are designed to remove 99.97% of all particulate 0.3 microns and above and are rated at a MERV 17. For reference, hair is 25 microns in diameter.
There are 6 different types of white blood cells and they all have different sizes. They are measured by diameter in micrometres (or pm). Neutrophils are 10-12. Eosinophils are 10-12. Basophils are 12-15. Lymphocytes are 7-8. Monocytes are 14-17. And macrophage, which is found only in humans, is 21.
White blood cells have a variety of different spacial features. They are two types, granulated and agranulted. They can vary in size from about 7 microns for a lymphocyte to 21 microns for a phagocyte.
