Water quality is a niche topic, but always an interesting topic of conversation. No matter what state (or country) you travel to, locals will have strong opinions. The water that flows from your kitchen sink may taste good, but it could still contain bacteria, heavy metals, and other unwanted contaminants. Or maybe you actually don’t like tap water, which is all the more reason not to drink it. In any case, there are simple solutions to the problem. When you’re traveling, you might decide to buy bottles of filtered water, but luckily there’s a much easier and cheaper solution for everyday life: you can equip your home with a filter. Below are five of our top recommendations for under-sink filters, as well as some information about what makes each one so great. After all, staying hydrated shouldn’t be complicated!

What are the benefits of an under-sink water filter?

When you hear “filter,” you probably think of a pitcher filter, like a Brita or a Pur. These certainly have their advantages, but you should also keep in mind that jugs need to be refilled daily and can take up excess space in your fridge or on your countertop. Seriously, many pitchers are not designed to remove significant contaminants. So you can make your water look and taste cleaner, but the effect doesn’t always go beyond that. For more comprehensive filtration, consider investing in an under-sink filter. The right device will remove all unwanted particles far more effectively and will not get in the way of your work in the kitchen. Plus, your water still tastes great – like bottled water, but much fresher!

What you should consider before purchasing an under-sink water filter

The biggest downside to an under-sink water filter is that you have to figure out which one is best for your specific kitchen. Not every model is compatible with every faucet, and if your home has naturally low water pressure, you should pay special attention when choosing your filter type. Specifically, there are four main types (more on this below). The filter you choose will also need to fit in your base cabinet, so some measure is appropriate. A smaller, low-capacity filter might create more space, but it won’t release as much water as quickly as a high-capacity filter. Additionally, the larger the filter, the more expensive it often is, so you should keep that in mind too. Size and price also affect how often you need to maintain or replace your filter.

Types of Under Sink Water Filters

Depending on the type of filter you choose, you’ll need to change it every six months to every four years. Reverse osmosis filters typically last the longest and need to be replaced every two to four years. You also need to consider how many people live in your household and how often you all use each sink. For example, a sink used by five people will need to replace the filter more often than a sink used by two people. Some filters have a set replacement time specified in the instructions for use, while others may have a built-in indicator that lets you know when it’s time to get a new filter.

Another factor to consider before purchasing an under-sink filter is whether you want it to be tenant-friendly. Many filters require you to drill an additional faucet hole in your sink to install them. You may also need to drill the filter body into the side of the cabinet and drill a hole in your sink drain pipe. Before purchasing, be sure to read the assembly instructions and, if in doubt, remember that you can always seek the help of a professional! If you’re worried about risking your deposit, an under-sink filter may not be right for you.
