How Faucet water filters work

Most sink faucet filters are a Point of Use(POI) filtration system as they do not have their own storage tanks and produce water on demand. When you switch on the faucet, the filter immediately produces filtered water and there is no waste experienced as all the water that goes through the filter comes out as clean and healthy drinking water.

Some faucets come with their own faucet and storage tank that stores approximately gallons of water such as the reverse osmosis water filters. You can install the kitchen faucet water filtration system on your own to the faucet of your kitchen sink or you can hire a handyman.

What features to look for when purchasing a faucet water filter

1. Filter Capacity

The basic faucet water filters have a capacity of around 100-200 gallons of water and last 2-6 months depending on your water usage and also the impurities level. For families, the best faucet water filter capacity is one with around 700-2000 but is a bit more expensive.

2. Filter Change Indicator and Sensor

This helps to easily tell you when you need to replace the faucet filter instead of going through the trouble of guessing. Most faucet water filter models use a small light that indicates when the filter exhausts the end of its life. Some models actually count the number of gallons you have used with an electronic meter.

3. 360-degree Swivel

The ability to swivel 360 degrees makes the filter quite easy to use but this can be used with only the faucet water filters that mount on the faucet and not the countertop faucet ones.

4. Different finishes

Faucet water filters usually come in different finishes and you should be able to easily find a finish that matches your current appliances and fixtures. The most common finish is chrome which easily blends with your kitchen while matching with the faucet. Try to choose a finish that matches your kitchen faucet. Avoid choosing white plastic finishes as the color hardly matches anything in the kitchens.

5. Size

Most sizes of the faucet water filters are almost the same. The size of the filter matters because it is related to the water filter cartridge's size. The larger the size of the cartridge, the larger the filter. The size does not affect how the filter works just important for you to know how much space will be occupied.

6. Filter Cartridges

Filter cartridges are very crucial in any faucet water filter as they are responsible for removing any contaminants from your drinking water and thus you should have more information about them before making any purchase.

They remove up to 70 contaminants from your drinking water however they have a limited lifespan which you are notified of with the filter change sensor that comes with most models. Models that don't have the sensor most of the time use periodic filter changes of either 1, 2, or 3months. Always follow the manufacturer's recommendation of filter change.

7. Cost

This might be an important consideration that some customers may overlook. Ensure you check how expensive the replacement cartridges are of the model you want to purchase. Some are quite expensive while others are cheap and as a result lowering your maintenance costs.

Types of Faucet Water Filters

1. Facet Mount Water Filters

These are the most common types of water filters and you don't need lines or tubes because the faucet filter is a compact unit that is mounted on the faucet. These faucet mount filters use up small spaces and can be installed and maintained easily. A major downside is their capacity is 100 gallons of water or 200 gallons and not more.

2. Activated Carbon Faucet Filters

Depending on the model, activated carbon filters can remove a lot of contaminants from your drinking water at a slightly cheaper price, and also the models are quite convenient to use. A carbon filter usually removes contaminants from the water using a carbon block cartridge.

These filters work great for reducing any organic chemicals or chlorine and can also remove cysts and fine sediments. However, activated carbon does not easily neutralize germs and bacterias and also does not remove dissolved solids like iron and magnesium. These faucet water filters are sensitive to high temperatures and cannot be installed on a hot water faucet.

3. Countertop Faucet Filters

If you are looking for a high capacity filter, a countertop faucet filter is the best faucet for the job. The installation and maintenance are simple as the tubes directly connect to the faucet just like in the faucet-mount filters.

The main filter sits on the counter with tubes and brings water to it and takes it back to the faucet. They perform quite well because they have bigger filters that capture more impurities and they also last longer and need to be replaced once a year. To boost performance, some models use multiple filters as many as 10 at a go. A disadvantage of this is that they are costly and also need counter space

4. Reverse Osmosis Faucet Filters

For any high-performance faucet water filter system, a reverse osmosis faucet filter is the best. This is considered the best in water filtration systems which remove even the smallest contaminants during the filtration process which are hard to catch, for example, perchlorate and arsenic.

This faucet filter removes heavy metals and chemicals while removing harmful microorganisms. However, these filters are very expensive and bulky.

Benefits of Faucet Water Filters

1. Provides safe and clean water

The filter's purpose is to get rid of any contaminants or minerals in the water and thus making it clean and safe to drink it from your faucet. Drinking clean water removes chemicals that might be harmful to any of your family members.

2. Easy to Install

3. Saves you some money
