What water filter will remove arsenic?

Arsenic is one of the elements found in nature in free form. It can be relatively easily isolated from compounds. As a rule, arsenic in not drinking water appears when groundwater passes through a layer of earth that contains a large amount of pesticides and herbicides, and arsenic can also get into a not drink water source with industrial effluents. Include for heavy metals.

What water filter system are able to purify water from arsenic?

Many drinking water filtration systems can remove arsenic, but we recommend that you use reverse osmosis filters. They are best suited for purifying water from arsenic.

Reverse osmosis: How does it work?

Arsenic removal system is a drinking water purification technology in which a pressurized liquid passes through a synthetic membrane that retains approximately 98% of pollutants, salts and impurities.

Arsenic removal system is considered one of the most effective ways to prepare water. And not only in domestic conditions (for drinking) and in industry, but also to solve a more global problem — desalination and drinking water purification in regions where there are problems with drinking water. We tell you how the technology works.

What is osmosis

Osmosis is a natural phenomenon that underlies metabolic processes in wildlife. Thanks to it, organisms, for example, receive nutrients and remove waste products.

Reverse osmosis

Water filtered, without requiring energy expenditure. But if you put pressure on the part of the container where the solution is located, a similar process will start in the other direction — this is reverse osmosis system. During reverse osmosis system, a semipermeable membrane will allow water molecules to pass through, but will stop most of the salts, organic substances, bacteria and other impurities.

But to do this, you need to apply pressure that will exceed the natural water filtered.

What is a semipermeable membrane?

This is a special two-layer synthetic ro membrane. It consists of a selective layer — the barrier itself for impurities, and a reinforcing layer that affects the strength of the membrane. They are made from cellulose acetate, reinforced polyamide or thin-film composites.

Reverse osmosis filter technology is able to remove 90-98% of salts, organic substances, bacteria and other particles from water. A properly functioning system retains impurities with a molecular weight of more than 150.

The result is water that does not require boiling and cleaning in other ways.

For remove arsenic is effective in the purification of surface and groundwater, as well as salt water, not only in domestic, but also on an industrial scale. This technology is used in the pharmaceutical industry, in the production of food and beverages and in many other areas.

But reverse osmosis systems still have a drawback: they pass gases dissolved in water, such as hydrogen, oxygen or nitrogen. Because of this, there may be a slightly lowered pH level in the water purified by this method. Water with a reduced pH level acts more aggressively on metal, thereby increasing the intensity of corrosion of metal water pipes. And this, in turn, allows lead, copper and iron particles to get into the water.

If you constantly drink such water thanks to the filtration system, metals can accumulate in the body, creating potential health risks. But they can be avoided if you monitor the acidity of the water and the condition of the water pipes.

Water filtration system in everyday life

Home reverse water filtration system are small devices that operate at a pressure of up to 3 atmospheres. They produce several liters of water per day. This is not very much, but it is quite enough for an apartment or a house. Water after filter arsenic can be drunk immediately.

As a rule, arsenic filter membranes are changed or cleaned 1-4 times a year, depending on the quality of the incoming water. It is possible to understand that the time has come by external signs: the water pressure has decreased, pressure drops have begun.

What water filter will remove arsenic

The filter arsenic membrane is cleaned using reagents with high and low pH. All pollution is divided into several main groups of pollution:

Colloidal impurities — clay particles, coal dust and other impurities that have passed through pre-cleaning filter media;

Inorganic salts — calcium and magnesium carbonates, iron, manganese and other metallic compounds that create dense deposits in the membrane;

Organic substances, most often of natural origin, create mucus between the membrane sheets;

Biological fouling — colonies of algae and microorganisms that settle and multiply in the membrane body.

Deposits of inorganic salts will help eliminate acidic solutions (pH <7), and colloidal and organic impurities are eliminated with alkaline solutions (pH >7).

Important: all solutions for cleaning reverse water filter membranes are quite aggressive and can be dangerous to health, so we must not forget about safety, and it is better to contact the service.

What is the arsenic water filter made of

Water systems consist of several pretreatment sections, after which water enters a tank equipped with a semi-permeable membrane.

What water filter will remove arsenic

It is made of:

  • Cellulose Acetates;
  • Polyamide compounds;
  • Polyacrylic Acid;
  • Nylon.

It does not allow particles larger than liquid molecules to pass through, distillate is obtained at the output. Such filters are equipped with a special tank for collecting water due to the fact that it passes through the membrane slowly.

To ensure the necessary pressure, the system is equipped with a built-in pump, which significantly increases the cost of the kit.

It is recommended to purchase a water systems containing a mineralizing block in the kit, since distilled water does not bring any benefit to the body

How is the purification of water from arsenic?

If you turn to chemistry, you can find out that there is a huge amount of water softener remove arsenic, but let’s look at the most convenient way that can be used at home, or rather in filter media. Since arsenic filter is considered a heavy metal, almost any filter containing coal can clean it.

The operation of activated carbon filtration is based on the attraction of impurities to the surface of the sorbent by weak interaction (adsorption), the reaction of some pollutants with carbon filtration (chemisorption).

High – quality activated carbon exhibits the following properties:

  • Actively binds foreign substances, does not react to water molecules;
  • It is easily wetted with water, without collapsing at the same time;
  • Does not initiate oxidation reactions, tarring of impurities;
  • It has pores with sizes from 0.8 to 5 nm, which allows organic pollutants (petroleum products, pesticides, surfactants) to penetrate;
  • It has a large capacity for short-term interaction with water.
  • Backfill fillers of filters are subject to regeneration by washing.
  • After a few recoveries (up to 4 times), the activity of the coals does not decrease.
  • Long-term use of the sorbent is not recommended.
  • To fully recover, you need to activate. It is almost impossible to do this at home.

Important. Some fillers can only be disposed of together with the impurities accumulated on them from the water.

Water filter system are used to achieve the following objectives:

  • Discoloration of polluted water;
  • Removal of unpleasant smell and taste;
  • Extraction of organic compounds;
  • Release of biological impurities from the aquatic environment;
  • Fixing on the porous surface of disinfection products (chlorination) of water pipes.

Coal materials successfully cope with all common pollutants. Their characteristics may not be sufficient to purify water with an increased level of impurities containing high concentrations of hardness salts. In such situations, in addition to carbon filters, additional cleaning modules need to be installed.

Water softener remove arsenic are more effective than any conventional mechanical cleaners, but they remove impurities to a lesser extent than systems with reverse osmosis and ultrafiltration.

Maintenance features and how to flush the filter for arsenic.

Modern arsenic removal systems are unassuming in operation, do not require much effort for maintenance.

For water filter system with cartridges, cartridge replacement is easy. To do this, unscrew the cover with the key from the kit, remove the old cartridge, put the new one in its original place. At the end of the procedure, the lid is firmly screwed into place, eliminating the appearance of leaks in the future.

Attention. It is absolutely not necessary to allow the use of the arsenic removal after the expiration of the period specified in the accompanying documents.

The effective arsenic removal time depends on the intensity of the load on the sorbent. Usually, with an average consumption of a family of 3 people, the replacement of the carbon filter is needed in a month.

The indicators of exhaustion of opportunities are as follows:

  • The appearance of a taste in water;
  • Reducing the flow rate (for all filters except the jug);
  • Precipitation after boiling.

New arsenic removal filtretion system with automatic indication of the arsenic water filters status are very convenient.

In such cases, it is impossible to forget about changing the arsenic water filters. You have to pay a lot for convenience. Such units cost over 15 thousand rubles.

Some inventive consumers use an original method of checking the condition of the sorbent. They make a barely colored solution of potassium permanganate or any food coloring. They pass it through the arsenic removal filtration system. If the outgoing stream is colored, it means that the reverse osmosis filter needs to be changed. The idea is original and well-founded.

Washing the reverse osmosis filter of the water pitcher filters, made in the form of a balloon, is economically justified. To regenerate the abilities, the coal must be removed, rinsed repeatedly in clean water filtration systems, then you can repeat the procedure in a 3% solution of baking soda.

To restore the functions of the sorbent, it needs to be shaken, stirred, washed out. It is impossible to make a full-fledged regeneration of carbon cartridges at home.

Arsenic poisoning

Poisoning with arsenic and its compounds is an acute or chronic intoxication that occurs when the poison is ingested, as well as its ingestion by inhalation. The main symptoms are severe diarrhea, severe abdominal pain, vomiting, dehydration. A paralytic variant is possible, which is manifested by hearing loss, convulsions, and coma.

Pathology is diagnosed on the basis of toxicochemical examination, radiography, clinical picture. Treatment — non-specific antidotes, antitoxic and symptomatic therapy. Asenic include for heavy metals.


Arsenic from water poisoning is divided according to the form of flow. There are intestinal-toxic and paralytic types of the disease. Pathology is also divided by the type of toxic agent (intoxication with a pure substance, its inorganic or organic complexes).

It is possible to systematize according to the severity of the lesion (severe, moderate, lethal, light). Structuring according to the nature of pathology is of the greatest practical importance:

Spicy. It is determined by obvious violations in the work of several internal organs. There are symptoms of damage to the brain, intestines, stomach, respiratory apparatus, kidneys, blood system, cardiovascular structures. It has the greatest lethality in the absence of timely medical care.

Subacute. There are moderate changes in the activity of nerve tissues without obvious life-threatening symptoms. There is a decrease in intellectual abilities, encephalopathy. Non-lethal failures of the coronary rhythm, breathing difficulties, weight loss, periodic abdominal colic may be detected.

Chronic. A number of nonspecific symptoms are detected in the victim, which are not always possible to associate with the toxic effect of arsenic. There are complaints of periodic intestinal disorders, implicit elements of damage to the central nervous system and peripheral nerves, cough, skin symptoms. There is no immediate threat to life.

Symptoms of arsenic poisoning

The clinical picture of As intoxication is quite diverse, it depends on the type of damaging agent, its dosage and the period during which the poison entered the victim’s body.

70% of poisoning mainly has symptoms of gastrointestinal tract damage: metallic taste in the mouth, vomiting and nausea, epigastric pain, intestinal colic.

Due to copious diarrhea, a picture of dehydration occurs. Signs of damage to other systems in case of poisoning heavy metals :

  • CNS: weakness, inappropriate behavior, decreased memory and performance, seizures, coma.
  • Peripheral nerves: neuropathy, narrowing of the visual fields, pain in the extremities.
  • Respiratory apparatus: cough, swelling of the respiratory tract, wheezing, suffocation.
  • Blood system: erythrocyte hemolysis, agranulocytosis, anemia.
  • Kidneys: tubular necrosis, decreased functional ability up to acute renal failure.
  • Skin: baldness, swelling, hyperemia, rash, hyperpigmentation, keratosis, basal cell carcinoma.
  • Heart and blood vessels: rhythm disturbance, hypotension, arrhythmia, cardiomyodystrophy.

Acute arsenic poisoning manifests itself after 30-120 minutes that have elapsed from taking the poison. The death of the victim often occurs within the first hour after the occurrence of a characteristic clinic or after 1-3 days. The reason is the phenomenon of cardiovascular insufficiency caused by dehydration.

With a paralytic course, the lethal outcome is provoked by the paralysis of the respiratory and vasomotor centers.


The main complication in drinking arsenic lesions is severe exicosis. Massive fluid loss leads to a decrease in preload on the heart, a drop in coronary output and blood pressure, a collapse of the circulatory system, and the occurrence of hypovolemic shock.

If help was not provided on time, similar symptoms are detected in 80-85% of patients. With timely initiation of infusion therapy, dehydration can be avoided.

The second problem is considered to be a critical weakening of the function of several organ water supply — multiple organ failure.

Usually there is damage to the kidneys, liver, and heart. At the same time, the process of metabolism and excretion of the toxic substance slows down, which contributes to an increase in the severity of the pathology.

PON is diagnosed in 15-20% of victims with acute intoxication, delivered to the hospital a few hours after taking xenobiotic.

Chapter FAQ

Do refrigerator water filters remove arsenic?

It all depends on which water filters is used in the refrigerator to remove arsenic. If the filter is carbon, then the water will be remove arsenic, but if the water filters is not reverse osmosis, then most likely the particles of the toxic substance will get into the refrigerator.

Therefore, we recommend giving preference to reverse osmosis water filters or any other carbon water filters for removing arsenic. In addition, it should not be forgotten that filters need to be changed often so that toxic substances also do not get inside the refrigerator, and subsequently into food and products, because this can lead to serious health problems up to death. In refrigerators, filters are most often used to purify water, the same as in sinks.

When buying a refrigerator, we advise you to clarify in advance the question of which water filters you have, or immediately change it to the one that will suit you.

How to choose a filter?

The water filter for the sink is a flow—through water purifier, which is installed under the sink and connected to the water pitcher filter.

The water goes through several stages of purification, each of which purifies the water from different types of impurities, and exits through a separate faucet, which is permanently installed on the sink. There are water pitcher filter with a double tap: tap water flows from the tap in one position of the handle, purified water flows in the other.

The water filter under the sink can have from one to four stages of cleaning. The system of several water filter simultaneously removes large particles, chlorine, bacteria, softens water, reduces the content of iron and other metals.

Water filter with an ultrafiltration membrane purify water from all impurities larger than 0.1 microns. Different filters need to be changed at different times: some — every three months, others — every six months or once a year.

To choose the right water filter, you should understand what it needs to be cleaned from. The answer to this question will be given by any independent laboratory that analyzes the composition of water. After receiving the result, you can assemble a cleaning system suitable in this case.


New reverse osmosis water filters help total dissolved solids. Total dissolved solids is an indicator of a good filter. Remove arsenic is considered basic filtration. Each carbon filter should remove arsenic easily, since arsenic is a heavy metal. The remove arsenic from water is mandatory, as it contains many toxic substances.

Whole house water filter will supply your family with clean and fresh water softener. We hope that the article was useful and we were able to answer your questions.
