Which Carbon Water Filter Type To Choose?
And Things To Know Before You Buy...


A carbon water filter is basically just like any other filtration system.

It is mainly to absorb any impurity that could have found its way into the water. This includes rust, sediment, and dirt.

It is also used to get rid of the nasty odor and even bad taste of liquid, especially if they come from public water supplies.

Because it is highly cheaper than other types of water filters, carbon water filters are normally utilized by a lot of households.

Others, especially those that are being used in industrial applications, are known to get rid of the presence of coliform, asbestos, and lead in liquid. There are also a number of these carbon-based water filters that are considered to be excellent in trapping VOCs, or volatile organic chemicals.

Two Types of Carbon Water Filters

So far, there are two known kinds of water filters with carbon. These are the solid-block carbon water filtration system and granular activated carbon. Knowing and understanding their benefits and loopholes will allow you to come up with a much better decision when you're going to be picking your carbon-based water filter.

Solid-block Carbon Filter
Solid-block carbon filters are usually made of activated carbon that have been pulverized and transformed into very fine granules.

They are then bound together until the fusion will create a solid-block carbon.

Because the pores of solid-block carbon water filters are very fine, they're known to be highly efficient in filtering out disease-causing bacteria and viruses as well as coliform.

They can also get rid of cysts like giardia and a number of VOCs.

Moreover, the solid-block carbon-based filters can come in close contact with impurities, which make them also effective in removing them completely. There's also very slim chance for bacteria to grow inside the filter.

Granular Activated Carbon
When it comes to efficiency, granular activated carbon is just as superb as the solid-block carbon. It can get rid of gases and harmful chemicals from the water. It may even get rid of microorganisms.

However, this kind of carbon water filter is plagued with many problems. First of all, the impurities that remain in the filter can actually help breed bacteria inside it.

What's worse, there's a huge tendency that these impurities can find their way back into the water, especially when the carbon filter has already reached its saturation point. The impurity level is then much higher than the untreated water.

Things to Remember in Carbon Water Filters

Thinking of purchasing your own carbon-based filters? Then consider the following notes:

1. Carbon filters require constant maintenance. Block filters should be changed more often than granular-activated carbon filters.

2. There are several types of carbon filters that you can choose from. Your choice will practically depend on whether you want it to be seen or not.

If you like to keep your kitchen stylish as ever, you may want to have a carbon-based filter that you can install under your sink. Otherwise, you can simply go for one that you can mount on your faucet or place on your countertop.

3. You should realize that there's a big difference between a water purifier and a filter. A filter shouldn't be called purifier unless it has the ability to remove at least 99.75 percent of bacteria from the liquid.

4. Carbon filters cannot remove any inorganic material that is dissolved. These include lead, cadmium, mercury, and any radioactive material.

5. Don't be afraid to ask the sales representative some questions pertaining to your chosen carbon filtration system. Make sure that you pay for the right equipment.
