what is the micron rating of brita?

Hi Linda Google brita micron rating to get this answer. There is a wealth of information on this and other facts about the brita. There are arguments for and against it. It makes our local tap water palatable which is mainly why I use it. As a Brit I mainly boil it to make tea. Tea made with unfiltered water is unpleasant to say the least. Good luck with your research.

the manual states that it pulls down to 30 microns, but that would be dependant of some factors such as your local barometric pressure and what your using it for

Micron is a unit of length measurement. 1 micron equals .0000393 inch. Simply put micron filtration means it prevents extremely small particles of impurities from being in your water.

Microscopic is the only information I have. You could contact Luna for specification on that.

The MERV rating is a standards manufacturers use to compare the efficiency of filters. The higher the rating, the better the efficiency I picked the following information off another site "the following MERV ratings measure filtration efficiency of particles ranging from 0.3 microns and up. With more an more emphasis being placed on micro particles, 3M developed their MPR Micro Particle Rating to measure filtration of even smaller particles, down to .001. Some competitors are beginning to adopt the new standard that 3M developed but there is still predominant use of MERV. As a reference, the 3M Micro furnace filters have a MPR of 1000. Their rough equivalent MERV rating is 13-14. So while their is currently no sure equation way to convert MERV to MPR, if you use the approximate MERV rating of the Micro filter MPR rated at 1000, then the 4" filters MPR rated at 1550 would conceivably exceed MERV 18, which currently puts their filtration in line with the more expensive NordicPure furnace filters. Because 3M uses this different measuring scale and system, it's difficult to do a straight comparison."

I don't know about micron ratings. If my mask is rated 3 microns, then I suspect it would not protect against 2.5 micron particles.

I have not used mine yet, but the silt filter is 5 micron. the other 2 are charcoal.

It is probably too coarse for what you want at 75 microns. Yo are looking for 400 microns as the optimal filter for compost tea. Here's what you are looking for: 5 Gallon EZ Strainer Insert 400 Micron for Bucket Pail Filtering Water Paint Biodiesel WVO WMO Vegetable Oil

Just fed this about 10 minutes ago and the bottle says it contains particles ranging in size from under 20 microns up to 150 microns. Hope that helps - love this stuff!

As I noted in my review, all of the filters that I rec'd are marked 228 micron. It is my understanding that the "assorted" means that you could receive anything in the 90-190 micron range (even tho I rec'd 228 micron!); "assorted" does not apparently mean that you will receive an assortment of sizes.

I only know of Brita, (I have a brita now), and Pur. Both of these are plastic.

We have used this pump all summer and were able to pull down to 25 to 50 microns. Lots of factors that ratings would be of no use when pulling a vacuum on different systems.

The one I received was pretty close about 0.2 if I remember correctly. It is not really an issue though as it comes with chemicals to mix calibration solutions. You just need to mix it with distilled water.

Berkey doesn't publish micron ratings as they're a little misleading. From their website, if a filter traps of 0.2 micron particles then it's acceptable - even if the other 10% lets in 1.0 micron particles - to call it a 0.2 micron filter. But if you read the test results on their website, their filters are capable of filtering 99.999% of viruses and 99.9999% of bacteria. That's better than almost any filter out there. In fact, you test the filter by adding a teaspoon of red food coloring to a gallon of water and running it through the filter. I can vouch for the fact that in mine, the water comes out crystal clear.

It depends on the filtration level you are looking for. The smaller the micron number the cleaner the water will be. The tradeoff is if your water has more sediment then the filter will clog up faster. Or if you only need to remove sediment then perhaps the larger micron filter will do. I use a 1 micron filter since I want to remove as much as possible.

I really like these micro readers. Mine is 1.25 strength. It was very hard to find.

A micrometer, commonly known as micron is one millionth of a meter, one thousandth of a millimeter or one thousand nanometers. A strand ofhuman hair is about 100 microns wide and a red blood cell is approx. 8 microns in diameter. A Micron is .000039 inch or .001 mm. This filter is rated at .003 Microns! Get this filter!!
