Countertop water filters are the easiest to install type of domestic filters. They are the perfect fit for people who move a lot, people living in smaller households, and for those who don’t want to deal with installation and maintenance issues involved by other types of water filter systems. Which are the pros and cons countertop water filters? Is a counter top filter a good fit for you?
Advantages of countertop water filters
Minimal installation: Countertop water filters either don’t require any installation or they are installed by simply attaching a tube to your kitchen faucet. Gravity water filters are a special kind of countertop filters that require zero installation and you can carry them with you wherever you go.
No extra tap needed: Some filters (e.g. undersink filters) need a special filter tap that you have to install next to your existing tap. This requires you to create another hole on your kitchen sink to accommodate the filter tap. This may be a problem if you simply don’t want to damage your existing sink or the material the sink is made of doesn’t allow you to drill into it.
Easy maintenance: Countertop filters are one of the easiest filters on the market. You only need to replace the filters at the required periods.
Price advantage: Countertop filters are an inexpensive way of obtaining purified water at a single point of use.
Disadvantages of countertop water filters
Single point filtration: Unlike whole house water filters that filter all water that enters your home, point of use water filters like countertop filters only filter water that flows through the tap they are installed on.
Aesthetic considerations: These types of filters sit next to your kitchen sink, which may not be an aspect that is liked by everyone. Based on aesthetic considerations, some may prefer a more discreet solution, and opt for under-sink filters instead.
Efficiency: Being smaller in size than multi-stage water filters, they may not have the same contaminant removal capacity as multi-stage or other types of water filter systems. Other countertop filter types (e.g. gravity water filters) may not have a high filtered water output in terms of volume.
As with any type of filter, countertop filters will not remove any and every type of contaminant, especially that most of these filters are a single stage filter that contains only one type of filter media. More advanced countertop filters, however, contain more than one type of filter media (e.g. the H2O PCT Counter-Top Water Purifier contains KDF and coconut shell granular activated carbon for a more comprehensive filtration), and are indeed able to deal with a wider spectrum of contaminants.
