An inline water filter attaches to your existing water line, usually under the sink, to filter water as it flows through. It provides filtered water on demand, unlike pitcher filters, and has a higher capacity for contaminants. Compared to reverse osmosis (RO) systems, inline filters are cheaper and easier to install.

Types of inline filters include sediment filters (remove dirt, sand, and rust), carbon filters (improve taste and odour by removing chlorine), and ultrafiltration (UF) filters (remove bacteria and cysts). They are ideal for those wanting better-tasting water or targeting specific contaminants like chlorine or sediment.

How do water filters work?

There are various numbers of water filter brands available in the market. So, how do you decide which one you should choose for your home? Well, to conclude this, you should first understand how they are installed and work. Here is the complete breakdown of the whole process:

1.     Installation

These filters are directly installed into the water line, which supplies water to your refrigerator or ice maker. They are often placed in a convenient and accessible location for easy maintenance, such as behind or underneath the appliance. They can be easily installed and removed. Some filters even come with an installation kit, which mainly includes plumbing tape, screwdrivers, etc.

2.     Filtration

The number of filtration stages they have depends on the specific purpose and the level of filtration needed. There are Single-stage filters that typically target one specific contaminant, like sediment or chlorine in the water. And, there are multi-stage filters that have multiple filter cartridges stacked one after another. Each stage can target a different contaminant or provide a progressively finer level of filtration. Here are some common types of single-stage filters available in the market:

• Choose an Activated carbon filter if you want a water filter that removes chlorine to change the odour of the water.
• Want to remove larger particles like sand, dust, etc.? Choose a Sediment filter which will allow you to get clear water.
• Want to remove bacteria and cysts? You can consider choosing                                     

3.     Contaminant removal

Do you know how important it is to remove lead and other bacteria from water? These bacteria and lead can cause long-term effects such as nerve damage, kidney damage, diarrhea, etc. To remove these bacteria, it’s important to filter water. Inline water filters don’t just remove bacteria and lead but other contaminants, too, such as rocks, soil, pesticides, etc.

4.     Enhanced water quality

When all the impurities are removed, these filters dispense clean, fresh, and better-tasting water from your refrigerator.

Points to consider before buying

1.    Compatibility

The first thing to check before buying anything is compatibility. Check if your inline water filter is compatible with your refrigerator. Buying incompatible filters can affect the filtration process, allowing contaminants to pass through. Choosing a compatible one will ensure you get clean and safe water.

2.    Filtration capacity

Checking filtration capacity is one of the most important considerations when choosing an inline filter. If you need a filter for your whole house with a highly demanding kitchen, then you should choose high-capacity filters that can filter 100-5000 gallons of water.

If you want to install this filter for minimal use, like in refrigerators and ice makers, then purchase a standard filter that can filter out 500-1500 gallons of water.

Don’t know how to get filtered water while camping or in emergency situations? Don't worry—portable filters are here for you, and they can filter 100-300 gallons of water.

Before buying a filter, check its specifications to determine how much water it can filter.

3.    Replacement

Know how often you need to change your filter cartridges. Some models have indicators that will alert you when it’s time to replace the cartridge. This will help with maintenance and continuous filtration.

4.    Cost

While some filters may have a lower upfront cost, that doesn’t mean they require less maintenance. They may need more maintenance and cost due to lower quality material, smaller capacity and shorter life span—upfront cost, which may offer better filtration and long-lasting cartridges.

FAQs about inline water filters

• How often do filter cartridges need to be replaced?

Cartridge replacement depends on various factors, such as the filter’s capacity, water usage, and quality. Most manufacturers provide guidelines, and it typically must be replaced within 6 to 12 months.

• Are inline water filters difficult to install?

These are generally easy to install as many manufacturers provide a manual with guidelines and don’t require professional assistance.

• Does Inline water affect water pressure?

These filters may reduce water pressure because of the ongoing filtration process. However, there is minimal impact on water pressure.

Inline water filters ensure that the water flowing from your refrigerator or ice maker is clean, fresh, and safe by transforming tap water into clear water. Investing in an inline water filter is more than just a purchase. It is an investment in your health and convenience. While these might be a little expensive, the long-term savings from buying water bottles make them worthwhile investments. Let the clean water flow from your dispenser, knowing it’s leading you to a healthy future.
