Advantages and Disadvantages of Countertop Water Filters
If you are still trying to decide whether to buy a countertop water filter or go for the other styles like the under sink water filters, here are some advantages and disadvantages of the countertop filters to help make your decision easier.
1. Advantages of Countertop Water Filters
While countertop water filters are definitely not the smallest options they will take up little counter space. Most standard size ones will use up only 6 inches of counter space unlike the under sink types that can take up almost an entire cabinet.
Most countertop water filters are super easy to install, and you can have them running in just a few minutes. If you are using the faucet models, you will only need to connect them to the faucet, and they will be ready to use. For the fitcher types, there is almost no installation required besides assembling the unit.
These water filters will only cost a fraction of what you would pay for other filtration options such as the whole house systems. You can get a simple model for under $100 while the top-notch ones will only cost a little over $200.
Because there are no containers that you will need to refill or have to wait for the water to drip through, these water filters are also quite convenient to use. All you need to do is turn on your faucet and you will get filtered and great tasting water.
2. Disadvantages of Countertop Water Filters
Slower Filtration Rate
While countertop water filters are quite convenient and efficient, they do not filter water very fast or at least not as fast as other more advanced systems. Faucet mount models will have a relatively faster filtration rate than the fitcher types but are still quite slow.
Works for Standard Faucets Only
For those that use a pull-down or pull-out faucet type, this will not be an ideal water filter for you as it is designed to work for standard faucets only.
The tubing going from the faucet to the countertop filter can be a little awkward to deal with and will sometimes come in your way when working in your sink. Also, the long tubing is not very appealing if it looks to matter to you.
How to Buy the Best Countertop Water Filters
When it comes to picking best countertop water filter system, you need to watch out for the following things.
1. Fitcher or Faucet Countertop Water Filter
The first decision that you will need to make when shopping for a countertop water filter is the type to buy. Here you will often need to choose between the fitcher and faucet countertop water filters.
Fitcher Countertop Water Filter
The fitcher water filter models such as Megahome MH943TWS are the kinds that will not be connected to your water filter directly but are still highly efficient when it comes to water filtration.
While it might be a little inconvenient to use a water filter that is not connected directly to your faucet as you have to refill it manually, it can also have some advantages.
Some key advantages of using fitcher water filters include the fact that you can use it away from the kitchen like in the office. Also, it is convenient for those with a small counter space near the sink as they can place it in a separate counter.
Faucet Countertop Water Filter
Perhaps the more popular of the two types, faucet countertop like Apec Water Systems RO-CTOP water filters are designed to be connected directly to your faucet.
These are easy to use water filters that will attach to your faucet easily, and you will never have to refill a tank periodically meaning you will have a constant supply of filtered water.
However, it is not always easy to tell how much water you have filtered if the faucet countertop water filter does not have an indicator, and they will also require more frequent maintenance.
Before you buy any water filter, you need to consider the size and ensure it will be ideal and convenient for you. This is even more important for the faucet types because whatever you buy should fit the available space in your kitchen sink or the counter next to it.
Pitcher filters are also not an exception as their size should not only fit the space that you have but also not take up too much of it as you might still need to use the counter for other things.
3. Filter Capacity
Filter capacity is the amount of water that the filter on the countertop water filter can filter before it needs replacement.
Your water needs or the quantity of filtered water your family uses should help you in deciding whether the filter capacity is adequate for you or not.
However, the larger the filter capacity the better as it means you will go for many months or even years without having to replace the filter.
Some water filters will have a capacity of under 100 gallons while the larger and more expensive ones can filter thousands of gallons before they require replacement.
4. Ease of Use
The ease and convenience of installation and use of the countertop water filter will depend on the type that you choose.
Faucet types are easier to use than the fitcher types as there is no tank to refill as all it takes is to turn on your faucet to get filtered water.
However, whether you are buying a fitcher or faucet countertop water filter, it is important to note that those that come with detailed instructions are easier to use.
How to Install a Countertop Water Filter
Though different brands and models of countertop water filters will come with specific installation instructions, here are few general steps that you need to follow when installing most countertop water filters.
Step 1: Place Filter Next to Faucet
The first step is to place your new filter next to the faucet and make sure that it is close enough for the water line to connect the two. You should also turn off your water supply using the shut-off valve before proceeding to the next step.
Step 2: Remove Faucet Aerator
Next, remove the faucet aerator because this is where you will install your filter. Here you can do it by hand or with a wrench depending on your faucet type or how tight the aerator is fixed.
Step 3: Check the Thread
You will need to check the thread before proceeding as it will determine whether you need an adapter or not. If your faucet has an outside thread, you can proceed to install the filter. However, if it has an inside thread, you will need to first connect an adapter before screwing on the filter.
Step 4: Attach Diverter Valve
Once the filter is screwed in, you can now attach the diverter valve and turn the swivel collar to tighten it. Also, make sure that the gasket inside the diverter valve is securely positioned between the faucet and valve. You should rotate the diverter valve to the desired position and you may need to retighten the swivel collar.
Step 5: Turn Water On
When you turn on your water it should flow through the faucet as it would normally do. But when you pull the diverter knob or turn the handle depending on the countertop filter model, water should flow through the filter.
With the best countertop water filter, you will have an efficient, easy to use and affordable way of getting filtered water for your family.
