Whole-Home vs. Under-Sink Water Filtration: Which To Choose

If you’re looking for the right purification system to keep your drinking water clean and flavorful and wondering which to choose between whole-home and under-sink water filtration, continue reading to find which one might be best for you.


A whole-home water filter, sometimes known as a point-of-entry tap, is installed directly to where the main water line enters a home. This system removes impurities such as sediment, rust, chlorine, sulfur, and lead. One of the most significant benefits of this type of filtration is that it ensures clean water flows from each of your taps. Whether you’re doing activities such as taking a shower, getting a glass of water to drink, or washing dishes, you’ll have peace of mind that you don’t need to worry about contaminants. Furthermore, these systems add tremendous value to your home if you ever decide to put it on the market.


As the name implies, under-sink filters are put directly beneath a sink to filter water for drinking, cooking, and other uses. Unlike a whole-home system, under-sink filtration systems are considered point-of-use. They decontaminate water incredibly well, and they’re relatively simple to install and move when necessary.

They also don’t require a lot of room. They tuck neatly into kitchen and bathroom cabinets, hidden from view. Furthermore, they don’t need permanent plumbing modifications, so they’re perfect for rental properties. Simply attach the filter to the cold-water pipe that runs beneath the sink.

Which One Is Best for You?

When you’re figuring out which to choose between whole-home versus under-sink water filtration, your situation can significantly affect your decision. If you rent an apartment or move around a lot, an under-sink system can effortlessly improve the taste of your water, and you can reinstall it many times. On the other hand, a whole-house filtration system is the better option for heavy-duty contaminant removal from every tap in your home. These systems have a lot of advantages over point-of-use systems, including better plumbing maintenance and keeping appliances in good working order.
