Countertop Water Filters Versus Undersink Filter Devices

When the time comes to shop for a water filter, you could find yourself feeling confused. After all, there are plenty of different models to choose from. Do you need a countertop model or one that fits under the sink? It all depends on your personal needs and how your kitchen is arranged. Here’s a look at some of the factors that might be involved in choosing a water filter for your home.


Both countertop water filters and models designed for undersink use hit about the same price point. The difference is that you usually have a much wider range of options when it comes to undersink models. That’s because there’s more space available for multiple filter types. For instance, Aquasana offers three different undercounter models at several different price points. Their reliable countertop filters are less costly than the most complex undersink models, but you get fewer choices.


Countertop water filters have to sit on the counter. That means you’ll need to spare enough square footage to accommodate them. An undersink model tucks away into your cabinet, keeping it well out of the way. If you live in a home where counter space is a premium, it might be wise to choose a filter that doesn’t need to sit out in view.


You can easily hook a countertop filter up to your sink without any plumbing or carpentry expertise. When it’s time to move or if you want to use the filter on a different sink, simply unhook it and transport! That makes this kind of filter the one of choice for apartment dwellers and other renters. Moving an undercounter unit usually requires a lot more time and effort.


There’s no need to change your plumbing or modify your counter when you install a countertop filter. The device simply sits behind or to one side of the sink. When you install a model under the sink, however, you’ll need to make a few changes. Most require you to open up your sink’s inflow pipe in order to attach the filter. You might also need to drill a hole or two in the counter itself. These modifications are easy to make, but they could pose a problem for people who don’t feel handy or those who need to deal with rented kitchens.


Because they need to fit in small, relatively portable housings, water filters that sit on the counter are limited in their filtration options. You can use them to remove sediment, chlorine and its by-products, heavy metals like lead and mercury, and many industrial chemicals. These filters are also great for removing dangerous cysts that can transmit parasites. Most aren’t able to provide filtration for all types of contaminants, however.

If you’re not sure whether you need a higher quality filter, have your water tested and compare it to the device’s list of features. That way you’ll be certain to get the over or undercounter system that’s right for you.
