Discovering The Various Types Of Water Filters For Your Home

Is a faucet water filter enough to allow you safe water, or is it wiser to set up a water filtration system for the entire house? Is UV treatment or a smarter option? Finding an exact answer can be difficult. The type of water filter and the filtration method you use depend on a few factors. Some of these include your preferences, your budget, specs, and materials of the pipe, water pressure, biochemical properties of the water, etc. All of those vary from home to home.

In this article, we’ll look at the most popular types of water filters, making the whole process of selecting a water filter easier. Typically people install faucet filters, buy water in bottles or use water pitchers – very popular option that has been trending lately read more about filters for water pitchers here. All of these have their pros and cons and it us up to you to decide with what you should go.

Various Types of Water Filters and How They Work

Based on your application, there are several types of water filters:

– Absorption filters
– Mechanical filters
– Ion exchange filters
– Sequestration filters
– Reverse osmosis filters

All of these address a distinct water problem and most filters utilize a combination of these techniques to carry out multiple levels of filtration.

How Do They Work?

Absorption

More often than not, carbon carries out the absorption in a water filter, which is very effective at trapping water-borne contaminants. Carbon absorbs these pollutants so readily mainly because it has a huge internal surface that’s full of crannies and hooks that can catch chemical impurities like chlorine.

Many common residential water filters comprise granular activated carbon, which minimizes unpleasant tastes and odors through absorption. Expensive filters have carbon block filter components that are usually more effective and often come with a micron rating. Various substances are applicable in making carbon for filters such as coconut shell and wood; coconut shell filters are more expensive but effective.

Mechanical

Mechanical filtration aims at physically removing dirt, sediment, or any particles available in the water by using a barrier. A basic mesh that captures large debris can be a mechanical filter. A ceramic filer is also a mechanical filter but has a very complex pose design for ultra-fine filtration of various pathogenic organisms. A mechanical filter will often come with a micron rating which shows the effectiveness of the filter based on the size of particles it can remove.

Ion Exchange

Ion exchange, unlike scale inhibition, physically eliminates the hard minerals, lowering limescale and ensuring the water is suitable for usage where it’s maintained at a constant high temperature. Ion exchange resins are commonly used to carry out ion exchange and are usually in the form of small beads. Since water filters are normally sealed units, you could replace the filter. However, it’s worth noting that you can return Calcium Treatment Units to your supplier to get regenerated.

Sequestration

It’s the process involved in chemically isolating an element. Food grade polyphosphate is popularly used in scale inhibiting filters to isolate the magnesium and calcium minerals which bring about limescale and corrosion. Polyphosphate, however, is generally introduced in really small quantities and it only inhibits the scale instead of removing it. That implies that polyphosphate doesn’t soften the water but rather deals with maintaining the minerals within the solution, keeping them from forming a scale on those surfaces they get into contact with.

Reverse Osmosis

It’s the process of eliminating dissolved inorganic substances (such as calcium ions and magnesium ions) from the water by forcing it via a semipermeable membrane that’s under pressure such that it allows water to pass through but leaves behind most of the contaminants. Reverse osmosis is a very effective method of purifying water and is often combined with a few other water filters such as absorption (activated carbon) filter and a mechanical (sediment) filter to return water with some contaminants remaining.

Test Your Water Supply Before Choosing a Filter for It

Tap water can still contain some chemicals and other pollutants that may make it unsafe for drinking. This requires you to fit water filters to improve the quality of water.

Choosing a filter can be confusing because of the many different types of filters that are available for home use. Some of them are easy to install, some are easy to look after, while there are filters which require some care and maintenance. The filtration of water goes through the physical processes of sedimentation, filtration, and distillation. Filters also use biological filters like slow sand filters and activated carbon. Some use flocculation and chlorination which are chemical processes. Others use ultraviolet light or reverse osmosis to give you clean filtered water.

Water filters can use all the methods of filtration, physical, biological, chemical and others to provide you the required output of safe drinking water. Most water filters use carbon filters to remove large particles from your water supply and will trap silt and sediment. The use of these filters also reduces odor and improves the taste. There is a significant reduction of chlorine that is used by most municipalities to treat water. These carbon filters use activated carbon or charcoal that has been treated with oxygen so that tiny pores open up in between the atoms of carbon. This activated carbon is efficient at removing pollutants.

Reverse osmosis filters remove all hazardous contaminants and make the water free from odor. In this process, water is allowed to pass through thin membranes under pressure and removes all solids, dissolved liquids, and even arsenic and lead. Most reverse osmosis filters also have other carbon filters and water in them passes through two or three stages before it is allowed for consumption.

The electrolysis process is used in some alkaline filters and water ionizers. Water passes over plates that are electrically charged. This separates the water into two streams one that is acidic and the other that is alkaline. So you can get water that has very little acidity while also being softer, and therefore more suitable for the hair and the skin.

One of the latest technologies in use for water filters is the use of ultraviolet light. This light destroys all bacteria that can be dangerous to health. The fact that these filters use no chemicals or heat, makes them environmentally friendly. Some filters use infrared light to make the water softer. They use both light and heat to give the water a negative charge.

Reverse osmosis water filters remove all contaminants, minerals, and particles. They can be expensive to install and maintain. They also have a low flow rate and do cause some wastage of water. The removal of minerals that are essential in water may require separate devices to add back the required minerals. The best water filter for a home is better decided on the quality of the water that is being supplied to a home. Test your water, find water filters that can remove any detected impurities and those that are low in cost, easy to install and not too difficult to maintain.
