Water filters for your home
Water filters are usually recommended if you have a private water supply on your property with a high amount of sediment or is at risk of chemical contamination.
Many types of water filter are available for purchase or hire.
They range from the simple bench top style to sophisticated systems requiring special plumbing and electrical work.
How do water filters work?
Water filters work as a physical barrier that can block or trap debris (for example sand) and sometimes bacteria from passing through.
Generally, the speed of the water flow will depend on the size of the gaps in the filter barrier or membrane. A fine filter with the smallest gaps will mean a slower water flow. A clogged filter will also slow the water flow.
Careful consideration should therefore be given to the quantity of water required, and the time it takes to filter, before you buy a water filter.
Usually, water filters with a faster water flow are more expensive.
Will a water filter improve the taste and odour of water?
Several water filters currently on the market will effectively improve the taste and odour of water.
Filtration can remove tastes and odours whether they are naturally occurring or caused by a disinfection process.
Will a water filter remove bacteria?
Only a reverse osmosis water filtration system will effectively remove harmful bacteria.
The simplest way to remove harmful bacteria is to disinfect the water by chlorination or by ultraviolet radiation.
As some water filters remove biocides (substances that can control the growth of harmful organisms, such as chlorine), it is possible that bacteria will re-grow unless the filtered water is stored in a sterile container in a cool, dark place.
Some water filters may also allow bacteria to multiply to great levels on the filter pads if they are not maintained regularly.
In most circumstances domestic household water filters or ultra violet treatment systems will not make water safe in relation to amoeba unless you also disinfect with chlorine. Read more about amoebic meningitis.
Will a water filter soften hard water?
Some water filters will soften hard water. Hard water contains calcium and magnesium salts which results in:
- the need to use more soap
- a build up of scale on plumbing fixtures
- a metallic taste to water.
Filter types available
Water filters that are currently available to consumers include:
- polypropylene and ceramic
- activated carbon
- reverse osmosis and distiller.
The most sophisticated systems are reverse osmosis and distiller filters.
Polypropylene and ceramic filters
Polypropylene and ceramic filters function by removing particles from the water. Fibres are packed tightly together to form a fine mesh screen that physically traps and removes foreign particles from the water.
However, as these filters become clogged it is necessary to throw away the filter or cartridge and replace it with a new one. Some filters may also soften hard water.
Activated carbon filters
Activated carbon filters are most effective in removing chemicals such as iron, manganese, chlorine and hydrogen sulphide along with objectionable tastes and odours.
Some may also contain ion exchange resins that can soften hard water.
Polypropylene, ceramic or activated carbon filters should not be relied upon to disinfect water.
Reverse osmosis filters and distillers
Reverse osmosis filters and distillers are the most sophisticated systems. They are capable of removing bacteria and most residual chemicals, including minerals from a water source.
However, reverse osmosis and distillers are not effective in removing hydrogen sulphide (a gas with an unpleasant �rotten eggs� smell) in acidic waters.
How much do water filters cost?
The cost of water filters vary considerably.
Some water filters are simple two-tiered jugs while others connect directly to the kitchen tap and are located either on or under the bench.
Reverse osmosis filters are the most expensive to purchase, install and operate.
Which filter should I use?
For discoloured water with fine particles of grit and other foreign material, a polypropylene or ceramic filter will effectively remove the sediment. It will not remove bacteria.
To remove naturally occurring or disinfection tastes and odours from water an activated carbon filter is more appropriate. It will not remove bacteria.
To remove chemicals and bacteria, a reverse osmosis or distiller system would be required.
In most circumstances domestic household water filters or ultra violet treatment systems will not make water safe in relation to amoeba unless you also disinfect with chlorine. Read more about amoebic meningitis.
Does scheme water need filtering?
It is not necessary to filter water from scheme drinking water supplies in Western Australia unless you live in an area where you may need to soften hard water.
The Department of Health requires scheme drinking water suppliers in Western Australia to supply drinking water that is safe and complies with the Australian Drinking Water Guidelines (external site).
Routine sampling and reporting to the Department of Health ensures that drinking water provided to consumers is of the highest microbiological and chemical quality.
Water filters in rental properties
If you are renting out a residential property with domestic water filters, on either a short term or long term basis, it is best to ensure that the tenancy agreement or lease clarifies which party (the agent or the tenant) is responsible for maintaining the water filter and periodic replacement of any filter cartridge during the tenancy.
Checklist for buying a water filter
- Work out the volume of water that needs to be filtered.
- Decide on the type of filter that you need based on what you want to remove, for example odour, grit, chemicals.
- Buy a filter that has the standard WaterMark or Plumbing Safety Type Test mark.
Checklist for using a water filter
- Always follow the manufacturer�s instructions, including periodic replacement of any filter cartridges.
- Ensure the filtered water is disinfected prior to consumption.
- Store filtered water in a sterile container in a cool, dark place to prevent contamination.

Remember
- Water filters work as a physical barrier by blocking or trapping debris.
- Consult a water treatment professional to help choose the filtration method that best removes the contaminants you need to remove.
- Always follow the manufacturer's instructions.

The article author is making several good annotation on Water Filters in general in this post underneath.
Different types of water filters are available in the market as well as you can purchase these filters depending on your needs. There are various sorts of filters that can be made use of for different kinds of water needs. Below we will review some sorts of approaches for tidying up with water, that can assist people to filter pollutants from water.
To begin with, you can make use of a whole-house filtration system. These methods need to be set up in a specific place like the cooking area or bathroom. This system is usually utilized by people who are not very healthy or by people who do not want to purchase a separate equipment for each and every room in their residence. As the name suggests, this approach will get rid of all pollutants discovered in the drinking water.
In addition to the whole-house purification systems, there are other sorts of water filters that can be made use of for cleaning up with water. Several of these sorts of filters are chemical purifiers and also nano-technology filters. These filters are specially created to eliminate the pollutants present in water that is present in the air too.
The chemicals that are present in the air that streams in pipes are of such a wonderful danger that there are some chemicals that are known to be cancer causing. The federal government has actually know this and also therefore they have started a number of projects to avoid the spread of these chemicals in water products.
Chemical impurities in water can trigger a range of diseases like cancer, looseness of the bowels, belly ulcers, migraines, eye irritation, etc. They also position threats to unborn infants and also kids and also the children of ladies who consume dangerous water. Hence, it is very important that we make use of water filters that will properly remove all these pollutants from water.
The efficiency of water purification approaches depends upon the types of the materials that are present in the water. Water purification systems work successfully when chemicals are removed from the water that goes through the system. This method is referred to as non-selective filtration.
Various other types of water filters that are effective against chemicals include activated carbon filters and micron filters. These filters get rid of almost all the chemicals present in water without the requirement of having to be worried regarding the existence of any kind of poisonous substance in the water. Therefore, we can state that these filters are thought about to be very effective in eliminating damaging chemicals from water.
As we already understand that there are 2 types of filters that are effective against contaminations; these are the triggered carbon and also Website the micron top article filters. Since carbon as well as micron filters are extremely reliable versus chemicals, however the effectiveness of water filters that work versus pollutants depends on the type of water that is present in the pipelines. Given that it is just ideal that the water reaches its clients clean and also pure, consequently the water distributors should supply individuals with water filters that will certainly remove all the pollutants from water.
Approaches for cleansing water can be used in the house, as well as these techniques can be utilized to purify water for drinking, cooking, cleaning garments, washing, bathing, etc. Approaches for detoxifying water can be utilized to purify water by applying warm to it, or can be used by connecting the filter to the source of water and utilize the tap water to make ice cubes.
On the various other hand, individuals who do not have access to house water filtration tools can use ozone filtration systems for purifying water. These ozone filters get rid of all the impurities from water and also thus they are thought about to be really reliable in getting rid of the toxins existing in water.
Approaches for purifying water can be used to purify water for drinking, food preparation, cleaning clothes, washing, bathing, etc. This approach is called submicron purification method since it gets rid of water particles at one hundred thousand times lower than the water molecules. There are 2 types of these methods, initially one is ion exchange and the second one is reverse osmosis.
There are various other techniques for detoxifying water for alcohol consumption, food preparation, washing garments, washing, bathing, etc., but these 2 are taken into consideration to be the most common types of water filters. You can locate more helpful hints these techniques in different position on the net.
