There are several different types of chemically treated filters, each with their own advantages and disadvantages. They work by absorbing contaminants from your water.

These can be expensive over time, but do have long life spans. Their filter element life will depend on how often they need to be cleaned.

Chemically-based filters tend to cost more initially but will likely save you money in the long run if you use them repeatedly. Initial price differences between the varieties lie in the amount of filtering capacity they offer. For instance, ultrawide cartridges cost more than regular filters, while pur filtration systems are significantly cheaper.

When cleaning these filters, you’ll also want to take care that you aren’t too aggressive or moving them around so much that you risk breaking them. You can try putting them into your mouth when you don’t feel like doing it yourself.

Filtration processes

What is the best filter for drinking water?


There are two basic filtration methods used in water treatment industries: pre-oxidation and post-oxidation. Pre-oxidation takes place before any reverse osmosis or other purification process, while post-oxidation comes after the final purification step.

People have different opinions about which type of filter is better; it largely depends on one’s preferences.

Pre-oxidizers remove fewer particles from contaminated water than post-oxidizers. This may be due to them being exposed to more contamination prior to filtration. Particle removal rates vary between brands of filters; therefore, there is no “best filter.” Find out what results you should expect depending on the brand you purchase.

It can also depend how much time you have to spend optimizing your filters. For example, if you upgrade your filtering system today, then that might actually take you more time than replacing your filters every three months.

If you do not have the tools or expertise to optimize the filter itself, then consider partnering with a professional to make sure all your efforts are effective. They will know where others have put dependent systems that need maintenance.

Activated carbon

Although it may cost more at first, activated carbon is an affordable filtering method that can be worth its weight in gold. This inexpensive filter may eliminate chemicals such as pesticides, chlorine, ammonia, and hydrogen sulfide from your water supply, depending on who made it.

It also can remove heavy metals like aluminum, arsenic, cadmium, lead, and mercury from your water.

Some labs use this compound to purify water because of its antimicrobial properties. That means you can safely drink the water without worrying about bacterial contamination.

This content goes above and beyond what the EPA requires by providing numerous additional benefits such as disinfection byproducts reduction and improved taste.

Activated carbon works by trapping chemical molecules inside its tightly bound carbon particles. Over time, it slowly releases them back into the water supply, where they no longer can do damage.

There are two types of activated carbon: granular and packed. With packed carbon, there’s an advantage--it’s reusable. With granular graphite, not only is it reusable, but it can also be used directly for water filtration.

Packed carbon tends to be less expensive. However, since it can be reused, it has many advantages over granular carbon. For example, it removes heavier metals much better than granular carbons.

Reverse osmosis

What is the best filter for drinking water?


When it comes to filtering water, there are two popular methods. The first is using an appliance such as a filtration system with reverse osmosis technology. This filters out all of the contaminants in water, including pesticides, inorganic chemicals, heavy metals, and even uranium from nuclear waste.

However, this method can be expensive. Also, since these appliances filter everything out, they take up space and are not very efficient at removing certain things from your water.

The second method is to use gravity.

You place one container above another over a sink, then fill the lower bottle with water. Basic physics shows that the upper bottle contains less contaminant than the lower one if both have the same height.

This simple step has also been found to remove many kinds of particles present in drinking water. Its effectiveness depends on the shape and size of the particle.

Hard water filtration


Many residential systems have hard water filters. These filtrations can filter out chemicals and minerals in your water. They rely on manufactured carbon filter elements to remove these substances.

These are designed as temporary solutions to clean up water with high levels of salts and sulfates, common contaminants found in raw (unprocessed) water supplies. Once these initial levels are reduced, the frequency of required maintenance is significantly decreased.

Hard waters typically require replacement every 1–3 years. You can keep extending the life of your system by updating it more often than that. [substeps] Contact your local utilities office or look online for water quality reports to see what their recommended drinking standards are.

If you share your water source with other families, consider getting a dual-source water meter so that each household member has his or her own tank. This eliminates any risk of long-term chemical exposure from one family member’s mistakes.

It also helps ensure that no person receives an excessive amount of water per day because of lack of accountability.

Softening additives

What is the best filter for drinking water?


Even if your water comes from a private source, like a home filtration system, you may need to treat it to remove mineral and other contaminants. While these substances can be harmful in large amounts, small levels of minerals are safe.

However, when consumed in excess, for example, in watermelon rind or oysters, heavy metals such as lead, mercury, arsenic, cadmium, and zinc can poison your drinking water.

Common ingredients used to soften water include carbonates (such as limestone), citrate, melaine, alginate, and starch. Only moderate quantities should be added since excessive softness is not desirable during hard boiling.

Chitin and chitosan have been shown to reduce the amount of microorganisms in water by binding with cell walls and capsular material around microbial cells. These oligomers work well because they are natural substances found in many shells and fungi.

Treating water with chlorine

What is the best filter for drinking water?


Although chlorination is one of the most effective means to disinfect drinking water, it does have some shortcomings. First, as with any medication, there are levels of toxicity. At higher doses, diarrhea, vomiting, headaches, etc., can be the result. Second, although pathogens are killed, other contaminants in the water remain. Third, stability problems can sometimes cause membranes and filters to fail. Finally, overuse increases risk of cancer. For these reasons alone, I recommend using natural methods first. If all else fails, sterile distilled or chemically-free bottled water may be used.

Copper sulfate

What is the best filter for drinking water?


Though it may be more commonly known as copper sulfate, it is actually made up of two different chemicals- copper oxide and sulfur dioxide.

It can either be used in dry form or in fluid form. When used in liquid form, it is generally labeled as saltwater because it contains other substances. However, it is also available in tablet form which makes it easy to administer.

When dissolved into water, this creates an oxidative compound that kills harmful bacteria and viruses. Unfortunately, it cannot kill all types of pathogens and has no effect on fungi.

However, this does not mean you should leave it out; its use in drinking water has been shown to improve health by providing vitamin C. Furthermore, studies show that exposure to copper can impart beneficial effects similar to those provided by ascorbic acid (vitamin C).

Due to its oxidizing properties, copper can bind with nitrogen compounds and reduce their ability to cause disease. It does this by breaking down nitric oxide, which in turn reduces inflammation and scarring.

Copper binding also helps remove reactive oxygen species from the body. When consumed in excess, copper can promote oxidative stress in the liver and kidneys. This can lead to cell death and tissue damage there.

For these reasons, the EPA limits copper intake via drinking water to 0·3 mg/kg total diet. For reference, a 200 pound person would need at least 2 cups per day less than that
