Brita filters can feature in tap faucets or certain pitcher jugs or water bottles. People may use these filters to remove the components of water that affect its taste, smell, or safety.

Water filters vary in design depending on their purpose, and there is currently no single type that can filter out all contaminants.

The taste of tap water varies slightly among water treatment systems and depends on the water’s source. This variety occurs because the concentration of components in the water differs from sample to sample. Brita provides different filtration options that can change how water tastes.

This article looks at how Brita and other water filters work, including what they filter and their effectiveness.

Water filters work differently depending on what they are trying to remove. For instance, a filter may catch microscopic parasites and prevent them from leaving the jug while allowing other components of the water through.

A Brita filter will come with a National Sanitation Foundation certification that a person can use to see what components of water the product will filter out.

How often do filters need changing?

Brita recommends changing its water filter every 2–6 months, depending on the type of dispenser or pitcher.

In most cases, this will mean that people can filter 40–120 gallons of water before a new filter is necessary.

According to Brita, standard filters work like a sieve, using carbon to lower mercury content and the taste and smell of chlorine. There is also an ion-exchange resin to filter zinc, copper, and cadmium.

These filters also have pores that control which components get through the filter. These pores come in different sizes, which may affect the filtration results.

The products Brita supplies include:

  • pitchers
  • dispensers
  • replacement filters
  • bottles
  • faucet systems

Brita states that it differs from competitors because its filters can eradicate more contaminants. They also reportedly last longer and are more environmentally friendly.

A few examples of Brita products are below.

This dispenser is available for $44.99, has an 18-cup capacity, and stores over a gallon of water. It features a slim design for easy storage.

Its filter can last for 6 months without needing a fresh one. Brita also claims the filter reduces more contaminants than competitors, including 99% of lead.

Ultraslim Stream Water Dispenser

This dispenser costs $44.99 and features a 25-cup capacity and a sleek design for easy storage.

It features a Stream Filter that filters water as it exits the dispenser. This filter needs replacing every 2 months. In hard water areas, individuals may need to change this more regularly.

Premium Filtering Water Bottle – Stainless Glacier

This stainless steel bottle is available in one color and retails for $24.99. It features a double-wall design, which reportedly keeps water cold for 24 hours. It can contain 20 ounces (oz) of liquid.

The filter fits inside the straw and filters as a person drinks. They are free from BPAs and reduce chlorine and particulates.

Premium Filtering Water Bottle – Hard Sided Plastic

This product represents Brita’s largest capacity bottle, which holds 36 oz of water, comes in four colors, and is dishwasher safe. The material consists of hard-sided plastic, making it more durable.

A person can wash and replace the filter within the bottle, and Brita recommends changing it every 2 months.

LongLast+ Replacement filters

Replacement filters for all Brita products are available for purchase online.

Brita claims the LongLast+ filter removes more contaminants than its standard filters, including 99% of lead. The brand also states it fits all pitchers and dispensers except the Stream range, and a person only needs to change these every 6 months.

They are available for $16.99 for one or $29.99 for a pack of two.

Standard Replacement Filters

A person can purchase these filters in a pack of one, three, four, five, six, or 10.

Basic Water Filter Faucet System

In addition to the above products, Brita also sells faucet systems to filter water straight out the tap.

This basic system retails for $19.99 and is available in two colors. The filter needs changing every 4 months on average.

What a filter removes from water varies among products, but Brita states that the filtered substances include:

  • asbestos
  • benzene
  • cadmium
  • chlorine
  • copper
  • lead
  • mercury
  • zinc

People may have differing opinions on whether it is important to filter water.

In the United States, public water filtration systems remove contaminants so that the water is safe to drink by the time it reaches the tap. However, filtering water can change the taste and odor to boost its appeal.

Sometimes, individuals refer to water as tasting “hard” or “soft.” This taste spectrum comes from the water’s calcium and magnesium content, which is higher in hard water. However, these essential minerals are good for the body.

The taste of soft water may indicate a reduction in mineral content. Studies have suggested that this lower content can lead to deficiencies that increase the risk of some diseases.

Fluoride

According to the Centers for Disease Control and Prevention (CDC), 73% of the U.S. population use community water systems. These systems have enough added fluoride to help prevent tooth decay.

Brita advises that its filters retain a healthy amount of fluoride.

Chlorine and chloramine

Small quantities of chlorine and chloramine play a role in community water systems, working as disinfectants and killing germs, such as Salmonella and norovirus.

Research has shown that small amounts of chlorine do not have harmful health effects in drinking water but can protect the body in the event of a waterborne disease outbreak. The same is true of chloramine.

All types of Brita filters remove a high percentage of chlorine.

Certain health conditions

Some people may need to avoid certain water components or contaminants for personal health reasons. In these cases, using a Brita filter can be effective in eliminating unwanted substances.

In the U.S., it is possible to order a customer confidence report from community water providers. These reports will determine the ratio of water components from individual systems. A person can then decide whether there are any components in high quantities that they wish to filter from the water before drinking it.

Collecting water through a private source means that it is not subject to the same regulations as public water systems, so it is up to individuals to filter the water appropriately.

According to the Environmental Protection Agency (EPA), approximately 10% of people in the U.S. use private wells to obtain their drinking water.

However, certain contaminants can get into the system, including pesticides, antimicrobials, and prescription medication.

Therefore, if using a private well, it is advisable to have a state-certified laboratory test the water at least once each year. The results will show the water components, and a person can then use an appropriate filter to remove any contaminants present in high concentrations.

Despite regulations, some contaminants can enter tap water after treatment. One of these products is perfluorooctanoic acid (PFOA), a compound that has links to kidney and testicular cancer. Brita does not claim its products filter PFOA.

Unnatural contaminants can also cause adverse health effects. For example, studies suggest that consuming agricultural contaminants in drinking water during pregnancy can lead to complications and congenital abnormalities.

Other components filtering systems should aim to remove from water include parasites and lead.

Filtering water lowers the chances of contaminants causing harmful effects.

As with most water filters, Brita filters restrict contaminants in drinking water. They will filter out different components, depending on the model.

In the U.S., the Safe Drinking Water Act (SDWA) regulates public drinking water. As a result, the country has some of the safest and most reliable tap water globally.

A person may choose to filter tap water if they have concerns over harmful contaminants, wish to change the taste or smell, or have individual healthcare requirements.

SDWA safety standards mean that the treatment process that water goes through before it reaches people’s homes removes harmful contaminants or reduces them to a safe concentration. However, private water systems are not subject to SDWA regulation, so it is best to get a laboratory to assess the water for contaminants at least once a year.
