An inline water filter is a filter that you install directly to your home water supply line that leads to your appliance or faucet that consumes water. This filter comes with one primary role – to eliminate contaminants and odor from your water.

But how are inline water filters different from other water filtration systems. I have already mentioned that they have a different installation method as they are fitted in between your water line and appliance. Other ways in which these filters are different include;

  • They have a compact design, making them ideal for homes where space is at a premium
  • They can easily be used as a pre-filter alongside other systems like a reverse osmosis water filtration system to purify water further
  • You can connect them to home appliances like ice makers, coffee makers, fridges, and so on. You can use them with appliances that have lower workflow rate

Also, inline water filters offer you an affordable way of filtering your home water making it healthy and clean for drinking and cooking.

Unlike the notion that most homeowners have regarding inline water filters that they are all the same, different inline water filters vary greatly based on intended purpose, functioning, features, and so on. This explains why you need to choose your model after careful consideration to ensure it meets your water filtering needs.

Below, we review the top 5 top-rated inline water filters that are enjoying extensive usage in many homes.

Inline Water Filter Buyer’s Guide

Benefits of a Water Inline Filter

Modern inline water filters reduce contaminants that previously could only be removed using a reverse osmosis system. Old models of these filters only used activated carbon filters to eliminate contaminants, but modern models have cartridge filters and carbon filters making them very effective in eliminating virtually all the contaminants.

Here are major benefits of using inline water filters;

  • Remove bad tastes and odors- most modern inline water filters use several activated carbon water filters. These filters are very effective at removing bad tastes and odor from the water.
  • Chlorine removal- carbon filters eliminate chlorine from your drinking water. Models with double carbon filters trap most chemicals and contaminants from water with the first filter and chlorine with the second filter thereby ensuring you drink pure, healthy water.
  • Sediment removal- the inbuilt cartridge filter removes sediment from the water. This is made possible by the spun polypropylene or pleated polypropylene in the cartridge
  • Bacteria and microorganism are also removed from your water. The cartridge used by your inline water filters also block bacteria and harmful microorganism such as giardia and cryptosporidium from reaching your faucet

How to Buy the Best Inline Water Filter

When buying an inline water filter, there are a couple of features you need to consider;

  • Water Pressure

When it comes to inline water filters, water pressure is an important factor to consider. It is very annoying to wait a long time for a glass of water to fill. Use a water filter that can deliver good water pressure especially if your home water supply doesn’t have enough pressure. Modern inline filters offer a better water pressure than traditional ones. However, one downside of having the filter increase water pressure is that the water spends less time in your filter and thus some of the contaminants might bypass the filters. This might be a problem if your home water is highly contaminated. If the water supplied to your home is quite clean, the number of contaminants reaching your faucet will be insignificant.

  • Ease of Installation and Frequency of Filter Change

This is another important factor you need to consider. You might wonder why installation matters since you are installing the unit once, but the fact is that if the filter is difficult to install, you might damage it in the process. Another reason you need to buy a unit that is easy to install is that you will not need to hire a plumber for the installation work.

These filters are designed as DIY projects, and thus there is no need for hiring a professional. If you encounter difficulties during the installation process, the chances are that you will find a detailed video tutorial that might help. You can also call the model manufacturer to get more details as well. More often, customer service will provide more valuable information that will help you finish your installation process fast.

Besides, go for models that have an easy process of changing filters. All the models we have reviewed here use filters that can be changed easily. However, you will find other models on the market using filters that are really difficult to change. This can be problematic if you are to change filters more often.

  • Filtering Capacity

Depending on the number of filters and components of the filter cartridge, some inline water filters will be more effective at removing some contaminants than others. Some models are very good at removing most of the contaminants but lack the capacity to remove specific contaminants. That’s why you should use a water quality testing kit before buying an inline filter. A kit will show you the level of each contaminant in your water source. You then use this information to look for a model that is efficient at removing these particular elements contaminating your water.

  • Cartridge Longevity

From the above reviews, I’m sure you have already noticed that most models need new filters every one or two years. Most cartridges work in the same way, and thus you need to check a model with cartridges that last longer and made of high-quality components. However, remember that cartridges longevity depends on the quality of your home water supply.

When Should You Change a Water Filter Cartridge?

There is no accurate answer to this question as some models will need a filter change every 6 months while others can last up to five years before they need a replacement.

You should read your manufacturer’s instruction to know the optimal time to change the filters. Some systems will notify you when it is time to replace the filters.

How to clean and replace a cartridge in your inline water filter

This process varies according to the model, but here are some steps that are common for all filters;

  • Turn off your water supply
  • Drain all the water by opening the faucet
  • Use a screwdriver to open the casing or the tool recommended by the manufacturer
  • Remove the filters
  • Clean its casing
  • Replace the filter and close the casing
  • Turn on the water to check for leaks

Conclusion

Inline water filters offer a perfect balance of size and filtration; they are ideal for small spaces or if you want to protect your appliances. All of the best inline water filters we have reviewed here are easy to install and maintain, and they are highly effective at removing contaminants from your drinking and cooking water.
