How to Buy the Best Faucet Water Filters
When it comes to choosing a good faucet water filter, you will need to consider the following important things to ensure you make the right choice.
For any faucet water filter to be useful for you, it will first need to fit your tap. Luckily the best ones are often designed to be compatible with various faucet types and sizes.
However, it is important to note that sometimes you will need to buy faucet adapters and other things like extensions hoses to make a filter more usable with you faucet. Luckily many top models like Culligan FM-15A will come with adapter for all sink nozzles which makes them an excellent buy.
Besides fitting your faucet, it will also be important to consider the size of the filter when it comes to compatibility. The main reason for this is to ensure that it will not look awkward or comical on your faucet.
2. Your Needs
Your particular needs should always come first when it comes to choosing a faucet water filter. You need to consider things like the amount of water you want to filter every day, and the types and number of contaminants you want to remove.
Also, the style of the filter and its finish should suit your particular tastes and preferences to ensure that you get maximum satisfaction from having it.
3. Direct Flow or Side Offset Flow Faucet Water Filter
As faucet water filters continue to become a standard fixture in most homes, manufacturers are always coming up with different styles and types to suit different consumer needs.
However, most will often fall into two broad categories which are direct flow and side offset flow faucet water filters.
Direct Flow Thru
As the name implies, these are the types of faucet water filters designed to attach to the end of the faucet and extend out from it. They provide great water quality and are also quite affordable.
However, they have a small surface area, and so they will not filter out particles that are as small as what the side offset filters do, and they will also require more regular replacement.
Side Offset Flow Thru
Side offsets are the most popular faucet water purification filters. The main reason for its popularity is because it allows you to use a larger filter since it is not directly under or in line with the faucet.
The larger filter cartridges will not only last longer but also filter the water more thoroughly when compared to the direct flow types.
These filters are easy to install, and activating them is also straightforward. However, these water filters are more expensive than the direct flow types, and will also add more weight to the faucet which can cause stress in some instances.
4. Carbon or Reverse Osmosis Faucet Water Filter
As you try to figure out the right faucet water filter to buy, you will also need to consider the type of filters they use. And here the two main options are carbon and reverse osmosis filters.
If you have one of the common carafe type water filters, then you already have some experience with carbon filters. Carbon filters work by absorbing water and then trapping the impurities before allowing the clean water to pass through.
These filters are effective in removing a wide range of contaminants such as pesticides and even lead depending on the type. Also, they are more affordable and convenient than the reverse osmosis filters.
Reverse Osmosis Filters
Reverse osmosis filters feature an ultra-thin membrane that is often made of acetate. With these filters, water is passed through the membrane under high pressure and it squeezes out more contaminants than most other types including the carbon filters.
However, these filters are often pricier and bulkier which is why they are installed under the sink. Besides changing their filters regularly, you will also need to replace the membrane after at least every two years.
The best faucet water filters are ones that feature a mostly metal construction as they are the most durable ones.
As a general rule, the metal filters will also grip the faucet tighter and are also know to filter much better and with fewer leaks if any.
The type of metal used to make the faucet and the finish also matter. Make sure that the metal is not known to produce any toxins to ensure water safety. For the finish, it is all about finding a material that at least matches your faucet and complements other fixtures and appliances.
6. Filter Cartridge
Because filter cartridges are what will do the actual filtration and removal of contaminants, it is important to know about them before going out to buy a faucet water filter.
The heavy-duty cartridges that will remove various substances from the water are the best choice as they are durable and provide better quality drinking water.
Filter cartridges will also have a limited lifespan which the manufacturer will indicate in the form of gallons that they can filter before replacement or the number of months you can use them.
A filter cartridge that filters the most amount of water before requiring replacement like the 1,500-gallon capacity one on the New Wave Enviro 796515300000 is often the best.
But, it is important to respect the manufacturer’s replacement recommendations to avoid drinking contaminated water.
7. Ease of Installation
Nobody wants to spend several hours installing something as simple as a faucet water filter. Also, you do not want to have to pay someone to do it, and so it is always important to choose one that is easy to install.
Luckily, most faucet water filters are super easy to install, and you will often not even need to use any tool during the installation.
Those that come with everything that you need in the box are often the most convenient and easiest to install. Some simple instructions can also be very useful.
How to Install a Faucet Water Filter
Even with the best tap water filter, you will still need to install it correctly to get its many benefits.
Luckily, most are easy to install and you will not need any special tools. Besides the hardware that comes with the particular faucet water filter, you will probably only need an adjustable wrench and Teflon tape.
Here is how to install the filter in 5 easy steps.
Step 1: Remove Faucet Aerator
The first step is to remove the faucet's aerator. But before doing this it will be a good idea to shut off the hot and cold water valves just to be sure no water will come out when working. In most cases, you should be able to remove the aerator by hand, but if it is too tight you should use the adjustable wrench.
Step 2: Clean Threads
Depending on the water source and the age of your faucet, there is likely to be some buildup on the threads at the end of the faucet. You need to clean them using some vinegar.
Step 3: Ready the Parts
Once the threads are free of residue and buildup and dry, the next step is to ready the parts that you will need. Here you will have to take out all the parts that came with the filter from the package and lay them in the counter.
Check the faucet threads to determine whether you will need an adapter to install the filter and if that is the case you can easily get one at your local store if the package does not include one.
Step 4: Attach Filter
Once you ascertain you have all the parts that you need, you can now attach the filter to the faucet. In most cases, this is all about twisting it in place. And after the mounting collar is in place you can then insert the cartridge to finish the installation.
Step 5: Activate the Cartridge
The last step is to activate or flush the cartridge, and all you need to do here is to allow the water to run for 5-10 minutes before tasting it. It is an important step that you should not skip as it helps to remove excess carbon. Also, check for leaks and if there are none, the filter is ready for use.
How to Care and Maintain the Faucet Water Filter
Like all other fixtures in your kitchen, the faucet water filter will also require care and maintenance to ensure it lasts long and produces clean and safe water.
Most modern faucet water filters will not require much maintenance but here are a few things that you should do.
- If you use a filter with a filter change sensor, make sure that you respect the indication and change the filter cartridges appropriately.
- For filters without a filter change sensor mark the date of the last filter change and use the capacity indicator to determine when to change the filters again.
- Use a clean rag and vinegar or lime juice to clean any limescale deposits that might build up on your filter.
- As you are replacing the filters, make sure to clean all the elements of the system and ensure you do not use any harsh cleaning agents to avoid adding harmful toxins.
- Remember to monitor the faucet water filter and the water quality keenly to determine whether the filter needs cleaning and if it is working correctly.
