Best Water Filter Pitchers

Water filter pitchers are designed to hold and purify a certain amount of water. Once you fill the container, the water passes through a system made up of one or more filters to provide you with clean and tasty water.

After the pure water is drained into the container, you can pour it into a cup where the design of the pitcher guarantees that it won’t get in contact with the filters or contaminants.

How Do Water Pitcher Filters Work?

The pitcher is filled with tap water that passes through a filter to collect in the container after it has been purified. Most pitchers have one or more filters.

Activated Carbon Filters

Most pitchers have an activated carbon filter that blocks impurities because their atoms stick to its surface. Activated carbon is usually made of coconut shells, coal or wood. After a while, the porous surface of the filter gets filled with impurities, reducing the purification rate and the ability of the filter to block impurities. This means that it’s time to change it.

Activated carbon can remove some contaminants from your drinking water, but not all of them. Here is what it can get rid of.

• Chlorine is a disinfectant that is usually found in municipal water. It changes the taste of water and can be related to several health issues.
• Chlorine also produces trihalomethane compounds when it gets in contact with the organic matter in water. Although the government limits the addition of chlorine, you want to make sure that the water you’re using for drinking and cooking is chlorine-free.
• Volatile organic chemicals or VOCs are found in herbicides and pesticides but they will find their way to drinking water.
• Some parasites are safely removed when the water passes through activated carbon. If your water is infected with Cryptosporidium or Giardia, you can make sure that it’s safe and clean if you use a pitcher with an activated carbon filter.

Cartridge Filters

Some filter pitchers have cartridge filters. These pitchers will let water pass through several stages to improve the taste and quality. Such filters will restore some of the minerals to your water, as they might get filtered by the activated carbon.

Tourmaline filters produce a small electric current that moves water molecules in a specific frequency that resembles that of your body. Water that passes through tourmaline will increase your level of metabolism.

What Are the Pros and Cons of Water Pitcher Filters?

Water filter pitchers are common household items because they’re affordable and require zero installation. Here are some of their pros.

• Water filter pitchers are lightweight and suitable for small households. They’re more budget-friendly than bottled water, especially if you’re worried about leaving your water in plastic containers.
• They’re versatile. You can keep your pitcher in the fridge to drink cold water all day long.
• Pitchers are portable and can be easily packed for a trip, guaranteeing access to clean and healthy water when you’re away from home.

However, these filtration systems come with a list of cons. You should consider them when you’re shopping for the best water filter.

• The filtrations process is slow. This becomes a real problem when you’re living in a big household.
• You’re limited by the capacity of the container.
• Charcoal filters need to be changed regularly. This makes pitchers a bit expensive in the long run.
• Pitchers can’t be used with heavily contaminated municipal or well water. They can’t get rid of most microorganisms, organic, and chemical compounds.

Best Whole-House Filters

These filtration systems are attached to your water main line, guaranteeing that all the water that gets into your house is purified and cleaned. These systems work with well and municipal water supplies because they’re made of several filters.

How Do Whole-House Water Filters Work?

These systems feature various filters. The first filter is sediment pre-filter that blocks larger particles and lengthens the life of other filters. Water will be free of most dust, rust, and debris, but will have to go through other stages of filtration.

The next filter is usually made of activated carbon. Through absorption, the particles of impurities get stuck to the large surface area of porous activated carbon. This will remove chlorine, VOCs, and bacteria. Most systems will have a copper-zinc filter that removes heavy metals and microorganisms.

If you have hard water, you can look for a filtration system that has a special softener. UV filters are essential if your water source is highly contaminated with bacteria, viruses, and other microorganisms.

What to Look For When You’re Buying a Whole-House Filter

First, you should think about the number of stages or filters. These will determine the type of impurities that your filter is designed to get rid of and how efficiently it can do that. Microns are also important to consider. Most filters are designed to block 1-micron particles, although some models can block particles as small as 0.35 microns.

The flow rate is another point to think about. If you live in a big household, you want a filtration system with a high flow rate, providing clean water for drinking, cooking, cleaning, and laundry.

What Are the Pros and Cons of Whole-House Filters?

Whole-house filters represent a practical option for busy households. They come with a lot of benefits.

• Your water consumption is purified using a single system. Whether you’re drinking, taking a shower or doing the laundry, you can rest assured knowing that the water is clean and free of impurities and contaminants.
• Whole-house filters are potent enough to treat heavily contaminated water. Some models are designed to purify well water and can soften hard water.
• Installing a whole-house filter saves you the hassle associated with installing a filter to each water outlet.

These systems, however, don’t work for every household.

• Whole-house filters are expensive and require professional installation skills. You might need to hire a plumber to make sure that the filter is installed at the right point. However, in the long run, these filters prove to be cost-efficient as you don’t have to change the filters as frequently as other systems.
• They don’t allow for fine-tuning. All the water is filtered at a single point, so you’re unable to get the desired quality at every water outlet.

Best Reverse Osmosis Water Filters

When all filtration systems fail, reverse osmosis systems can provide you with pure water. These systems are so efficient that they can remove from 95% up to 99% of all the contaminants in your water.

How Do Reverse Osmosis Water Filters Work?

These systems purify the water as it passes through several membranes and filters. They’re able to remove smaller particles, even dissolved ones improving the quality of heavily contaminated water. If you don’t have treated city water or if your water has a high content of salt, a reverse osmosis system can be used to make it suitable for your household use.

External pressure is applied to water, forcing it to pass through a semipermeable membrane. Only water molecules are allowed to pass, while all dissolved and suspended impurities will be blocked, directed towards the drain with wastewater. This wastewater might be returned to the main water supply, or directed towards another water outlet to water your plants or for laundry.

Unlike other systems, filters used in reverse osmosis systems will stay clean and won’t be replaced that often. These systems feature several filters to remove all types of organic and inorganic impurities including heavy metals, chlorine, and bacteria.

What are the Pros and Cons of Using Reverse Osmosis Water Filters?

Reverse osmosis technology is used by the food and pharmaceuticals industries to produce pure water. Here are some of the benefits of using a reverse osmosis filter in your household.

• These systems remove 99% of the contaminants that might still be present in your water after using any other filtration system. They can remove heavy metals, fluoride, pesticides, asbestos, and cysts. They can even be used to treat groundwater.
• The water produced smells and tastes better.
• Some models can be connected to your ice maker or fridge.
• Although these systems are potent at removing impurities, they’re quite easy to install. The filters may last for years.

But reverse osmosis water filters might not suit your household needs. Here are some of their cons.

• Most of these systems are expensive. However, you should think of your filtration system as an investment that will last for long.
• The water produced will taste dead or flat. This happens because reverse osmosis blocks all minerals and particles, even useful ones like calcium and magnesium. This is why it’s important to pick a system that features a mineralization stage, adding useful minerals to pure water.
• Each reverse osmosis system produces a significant amount of wastewater. This cost should be taken into consideration.
