What Does Micron Mean In Water Filters

When you're looking at a water filter, you'll probable come across amongst the technical specifications, each filter has a micron rating. But what does a micron rating even mean and why you should care about information technology?

In this blog, nosotros will discuss everything you should know well-nigh micron ratings and tips to select the best filter for your abode based on micron rating.

What is a Micron Rating?

To understand what a micron rating is we first demand to empathise what a micron is.

A micron is a metric unit of measurement, also known equally a micrometre, a micron is a millionth of a metre or a thousandth of a millimetre. It is denoted with the symbol: μm.

Anything roughly below xl microns in size is invisible to the naked human eye and would crave a microscope to see it.

The micron size of a water filter, otherwise known as a micron rating, will decide what size particles information technology's capable of trapping, and which particles may be small enough to pass through.

The smaller the micron rating, the effectively the particulate removed. A five-micron filter, for instance, removes particles as modest as v microns. Annihilation smaller passes through the pores.

Absolute vs Nominal Micron Filters

Filters work in different ways to filter contaminants. The corporeality that will become removed during water filtration depends on whether a nominal or accented filter is used.

Accented Micron Rating

An absolute rating refers to the largest particle that will fit through the filter, so a 1-micron absolute filter should foreclose anything larger than i micron from passing through 95% of the fourth dimension.

Just equally its name would signify, an accented micron rating retains 100% of particulate at a specified micron rating. Several conditions demand to exist in place for an absolute micron filter to effectively piece of work, including the water pressure, the concentration of contaminants, the particle size or diameter of the impurities, and even the method used by the filter to identify the impurity.

An example of this type of filter is a pleated filter.

Nominal Micron Rating

A nominal filter gives an indication rather than a guarantee of the size of particles that volition pass through, with some of the pores or holes in the filter surface existence larger than the rated size, they will let a per centum of particles through that match the micron rating.

Dissimilar water filters have varying levels of effectiveness depending on the material used to manufacture the filter organization, the testing method and surroundings, and the concentration of the impurities in question. Commonly, a nominal micron rating for a filter will remove be between lx and 98%.

Nominal rated h2o filtration systems are those that can remove a lot of chemicals, such every bit chlorine and chloramine, as well as some kinds of particulate and impurities that affect taste and olfactory property.

Carbon filters are a popular case of nominal micron water filters.

Most Common Micron Ratings

As all water contaminants are of varying sizes, different h2o filters have varying micron ratings and are designed to tackle dissimilar impurities.

75 microns to 100 microns

Water filters with a 75-100 micron rating are often used at a dwelling house's point of entry to eliminate large sediment particles from well and city h2o supplies.

50 microns

l-micron water filters accept larger pores that allow for the removal of particulates that tin can be seen by the naked eye, without such a clogging issue.

25 microns

Filters with 25-micron pores can be used to eliminate annihilation bigger than a white blood cell. It should prevent well-nigh particulates from inbound your drinking water.

10 microns

A 10-micron rating refers to a filter that can retain a relatively broad range of contaminants like grit, sediment, chemicals and metals. Generally, they are used as sediment filters and can be made of wound or pleated polypropylene.

5 microns

A 5 micron rated water filter helps to remove sediment, silt and annihilation that is 5 microns in size and bigger.

1 micron

Systems of around 1 micron in size are the almost effective option when based at the end of a filtration system and used for tackling fine particulates.

How many microns should your filter be?

In that location is no universal filter micron rating that works best across the lath. Different filtration cartridges have different micron sizes for a reason: because they're intended to retain and remove impurities of specific particle size or size range.

When deciding on how many microns your filter should exist, make sure to consider the following things:

Know What Your Are Removing

Knowing what is in your water is the first step in determining what micron rating the h2o filter has to be. Water filters with dissimilar micron ratings are able to remove a range of contaminants such as sediments, chlorine, fluoride, heavy metals etc.

If yous're looking to remove tiny bacteria and viruses, then probably a UV filter is your best selection. Similarly, if you want to remove excessive hardness in water, then a water softener is the ideal solution.

Level of filtration required

Nominal filters are pretty effective at contaminant removal, while absolute filtration will allow for the removal of 100% of the problem impurity.

That means yous're ever going to go much improve results with absolute filtration. Once more, there's no right answer here, as you may not exist looking to eliminate the full amount of impurities from your water.

Smaller isn't e'er better

A lower micron rating will filter out a much broader spectrum of impurities, but it does come up with downsides. Smaller micron filters can often struggle with problems with flow, particularly if your water is sediment-heavy and may demand to be replaced more frequently, too, because of bottleneck.

To ensure there is fiddling to no flow loss, a filter with a higher micron rating or a larger pump is required.

Choose a Reverse Osmosis System

Reverse osmosis systems involve a multi-step filtration procedure that uses a combination of different filtration media with unlike micron ratings to eliminate contaminants of all micron sizes such as sediments, silt, heavy metals, fluoride, chlorine, pesticides, cysts etc.

As an example, our popular Ecosoft 5 stage reverse osmosis organization uses 5 different stages to purify water.

Stage one involves polypropylene sediment pre-filter with a 5-micron rating removing big particles of mechanical impurities (silt, sand, rust, scale).

Stage two involves a granulated activated (GAC) filter with a 10-micron rating removing chlorine and other organic compounds from water to improve taste and remove whatever odours present.

Stage iii is another polypropylene sediment pre-filter with a 1-micron rating that removes fine mechanical impurities which may accept passed on from 1^st stage.

Stage 4 is the semi-permeable membrane which at the molecular level removes everything from the h2o including cryptosporidium leaner and cysts.

Stage 5 is ordinarily a post-carbon filter that acts as a polishing agent and eliminates dissolved gases in the h2o.

Some reverse osmosis systems like our Ecosoft 6 stage system, Stella contrary osmosis system, and Ecosoft PURE AquaCalcium system too enrich the drinking h2o with salubrious minerals by adding an extra remineralizing filter equally the last filtration stage.

If you are on a public h2o supply, then a opposite osmosis system is probably the best way to get the highest quality drinking h2o possible.
