Different accessories and add-ons are popping up as brands attempt to differentiate themselves in the filter space. These include Bluetooth capability and sensors that monitor and measure effectiveness. These accessories and add-ons can look great but they don't have to be. The sensor can be removed if you are following manufacturer instructions for replacing filters. It doesn't matter if the filter can remove the impurities that you desire.

Types Of Water Filters

Water filters are often thought of as a pitcher, however, water filters can also be used in almost any point along the water's path through your home.
Whole-home water filtration systems can be installed in your house to filter the water entering it.
- Under Sink: They can attach to or be under your sink and provide drinking water.
Faucet attachments: These are similar to under-sink filters and provide instant access water purification at the exact place you'd expect to get it, like your kitchen sink.
Pitchers are not as convenient as a sink filter and must be filled again.
- Countertop: Water filtration systems that are countertop work in a similar way to faucet filters. They divert water from the sink and filter it through a system which has its own tap.
- Water Bottles: The NSF and ANSI can certify water bottles as filtering water. You can fill them with water or let it filter as you consume.

Replacement Filters

Another thing you should consider is the cost of filtering. Water filtration systems are only as effective as the filters they contain. When deciding to purchase a filtration system, make sure you consider all factors, such as price, availability and frequency of replacement.


When purchasing a filter, you should also consider the water usage of your household. For smaller households, such as apartments or dorms, a pitcher may work well. However, if your household is larger or you need to filter water for drinking and cooking, you may want to consider using under-sink or faucet filters. It doesn't take much time to refill a pitcher, but it is easy to forget about it and just go back to the tap to get unfiltered water.


A water filter that is affordable for your personal use can be purchased. However, you should make sure that certifications are obtained. When deciding on what water filter to buy, you should consider its cost and the frequency it will need to be changed.

Installation And Maintenance

It is not as simple as installing a faucet filter to install whole-house water filters. It is necessary to shut off the water supply to your entire home, drain the pipes, cut the water lines, and then install the fittings. If you don't have any experience in plumbing or soldering plumbing fittings, a professional plumber will install your water filter.
The average cartridge lifespan is 3 to 12 months depending on how much water you use, your filter type, and the quality of the water. Most whole-house water filters make it easy to change the cartridge. Turn off the water supply and drain all lines. Then, unscrew or remove the filter tank and the cartridge. Install a replacement cartridge, attach the tank to the system, then recharge it.

Softening Capability

Some whole-house water filter systems can utilize heavy metal cartridges in order to decrease the amount of calcium and magnesium. However, many products come with sediment filter cartridges. These cartridges are designed to remove biological or chemical contaminants. It is advisable to get a combination whole-house filter/softener if you have hard water.

Types Of Contaminants

There are many contaminants that can cause water to be contaminated, from well and city water. Disinfectants, organic chemicals, metals and sediment are all common contaminants. There are three types of whole-house water filters: one, two, and three stage.
Three-stage filtration systems are best for removing the highest contaminants and improving water quality. However, it is a good idea check the National Drinking Water Database (EWG) to see what possible contaminants could be in your water.

Water Flow Rate

A whole-house water filter's water flow rate determines how much water can be passed through it in a certain time. The water flow rate is usually measured in GPM or gallons per minute. Whole-house water filters must have sufficient water flow to supply large appliances like dishwashers and showers.


What Water Filters Are The Best For Removing Contaminants?

There are many water filtration systems available, but none is better than another. Different types of filters may remove different contaminants, depending on the way they were manufactured or certified. We recommend that you know what contaminants you are looking to remove before searching for filters with a large number of removals. A water report can be obtained if you're unsure about the water quality in your area.

Can I Drink Water That Has Been Filtered Using A Whole-house Water Filter System?

Some whole-house filters have the ability to remove chemicals and harmful substances, but not all filters can do this. These filters are used to remove dirt, sediment and rust. It is better to test the water source before you drink it.

How Do You Clean A Water Filter Pitcher?

To keep your water filter pitcher in good condition, it is important to replace the filter. Although most filter brands suggest replacing filters after 40 gallons, this can vary from model to model.
Most water pitchers we tested could be washed as any other plastic kitchen equipment. The filter can be removed and washed by hand using hot soapy water. Be sure to rinse thoroughly to remove any soap residue. Many water filter pitchers can be washed in the dishwasher. Don't forget about the filter, which shouldn't be washed with soap.

Are Water Filter Pitchers Effective In Removing Bacteria?

No. No. A standard water filter will not help if your tap water is already treated for bacteria.
If left unattended for a long time, the water filter could become clogged with grime and bacteria that can then grow. You should change the filter as recommended by your brand every other month.

Are Water Filters Able To Remove Fluoride From The Water?

Yes, certain types do. You can specify a filter type, but make sure you check the certification.

Is It Possible To Filter Any Kind Of Water?

In short, absolutely. You can use water filters for both city water and well water. They are also suitable for soft or hard water (higher mineral content). Be aware of the specific minerals you want to filter. For example, a whole-house system that is specifically intended to remove hardwater minerals won't be the same as one that purifies chlorine for taste.

Is It Possible To Remove All Contaminants From A House Water Filter?

Whole-house water filters are capable of removing a lot of contaminants. However, water still flows through pipes and into the taps. This means that these systems can't guarantee 100% contamination.

What Is The Average Life Expectancy Of Water Filters?

Water filters are as good or worse than the water they filter. Most filters are meant to be changed, so certifications take into account the lifespan of each filter. To ensure that your filter lasts six months, it is recommended to test every filter. Filters that are regularly replaced can make the system last many years.

Are Water Filters Effective In Removing Bacteria?

The NSF certifies filters that eliminate bacteria according to a standard known as P231" but these are usually designed for outdoor activities such camping where you might need water from the stream. You should be concerned about the presence of bacteria in drinking water.

Is It Necessary To Have A Whole-house Water Filter?

A whole-house water filter is recommended for older houses with old plumbing. They can filter out dirt, rust and sediment as well as harmful chemicals and heavy metals. A whole-house water filter can be beneficial for homes even with brand new plumbing.
