Brita Complete Faucet Water Filtration System
For a simple and effective faucet-mounted solution, the Brita Complete is a household name for a reason.

It’s certified to reduce lead, chlorine, and other contaminants that can affect taste and odor. The flip-switch is convenient for quickly changing between filtered and unfiltered water, which is handy for tasks like washing dishes where you don’t want to use up the filter.
The filter life indicator is a simple but useful feature that takes the guesswork out of when to replace the cartridge. The flow rate is decent for a faucet filter, making it practical for filling water bottles and pots. While it won’t remove as many contaminants as a reverse osmosis system, it’s a great budget-friendly option for improving the taste of your tap water. It’s compatible with most standard faucets, making it a versatile choice for many homes.
Pros
- Extremely easy, tool-free installation

Installation is a breeze, and it fits on most faucets. The one-touch button to switch between filtered and unfiltered water is very responsive. I noticed a significant improvement in the taste of the water, with chlorine odor completely eliminated. The main thing to keep in mind is that, like all faucet filters, it does reduce the water pressure a bit. But for everyday drinking and cooking water, it’s a reliable and affordable workhorse.

It’s a great value for the price.

Installation requires some plumbing know-how, but the instructions are clear. The system has multiple filters that need replacing at different intervals, but it comes with a clear schedule. The water quality is exceptional, and the ability to adjust the filtration stages is a bonus for customizing your water. This is a great system for someone who wants the most thorough filtration possible and doesn’t mind a more involved setup process.

The system is built with durable, full-size filters that have a longer lifespan than many competitors. The all-in-one unit looks professional and is fairly straightforward to install. The permeate pump does require an electrical outlet under the sink. For me, the combination of high efficiency, great-tasting water, and robust construction makes this one of the best RO systems available. It’s an investment in quality and performance.
Pros
- Buying Guide: 10 Best Water Filters for Kitchen Taps | 2025
Choosing the right water filter for your kitchen tap can feel like a big decision. I’ve tested a bunch, and the best one for you really depends on your water, your budget, and how you use your sink. Let’s break down the key things to think about before you pick from our list of the 10 best water filters for kitchen taps | 2025.
First, consider the type of filter. The main options are faucet-mounted filters that attach directly to the end of your tap, and under-sink systems that are installed out of sight. Faucet-mounted models are great for renters or anyone who wants a simple, DIY installation. Under-sink filters require a bit more work to set up but free up space on your faucet and often have a higher filtration capacity.
Next, look at the filtration technology. This determines what gets removed from your water. Activated carbon filters are fantastic for improving taste and odor by reducing chlorine, sediments, and some organic compounds. If you’re concerned about a wider range of contaminants like heavy metals, fluoride, or nitrates, you’ll want to look for a system that uses additional methods, like reverse osmosis (RO). RO systems are highly effective but also produce wastewater and can slow down your flow rate.
Don’t forget about the filter lifespan and cost. A cheaper initial price tag might be appealing, but you need to factor in the long-term cost of replacement filters. Some cartridges need swapping every two months, while others can last a full year. Check how the system tracks filter life—some have simple timers, and others have smart indicators that monitor actual usage. It’s a good idea to confirm that replacement filters are readily available and fit your budget.
Finally, think about practical features. What’s the flow rate like? You don’t want to wait forever to fill a pot. If you go for a faucet-mounted model, does it have a switch to easily toggle between filtered and unfiltered water for tasks like washing dishes? For under-sink systems, does it include a separate faucet? These small details make a big difference in your daily experience.
FAQ
How often should I replace the filter cartridge?
This varies a lot by model and your household’s water usage. Most manufacturers recommend a change every two to six months. The best advice is to follow the guidelines for your specific unit. Many of the modern filters on our list of the 10 best water filters for kitchen taps | 2025 have indicator lights that take the guesswork out of it, letting you know when it’s time for a fresh cartridge.
Do these filters remove essential minerals from water?
It depends on the technology. Standard carbon filters typically do not remove beneficial minerals like calcium and magnesium. However, reverse osmosis (RO) systems are very thorough and will remove most minerals along with contaminants. Some RO systems address this by adding a remineralization stage at the end of the process to put the good minerals back into the water, improving its taste.
Can I install a water filter myself?
In most cases, yes! Faucet-mounted filters are designed for easy, tool-free installation that usually takes just a few minutes. Under-sink models require a bit more DIY skill, as you’ll need to connect to your cold water line and potentially drill a hole in your sink for a separate faucet. If you’re not comfortable with basic plumbing, hiring a professional for an under-sink installation is a smart move.
Will a water filter slow down my water pressure?
There might be a slight reduction in flow rate, but with a high-quality filter, it should be barely noticeable. Cheaper or clogged filters can cause a more significant drop in pressure. If strong water pressure is a priority for you, look for models that advertise a high flow rate. This is a key feature we consider when selecting the best options.
What’s the difference between a water filter and a water softener?
This is a common point of confusion. A water filter’s main job is to remove contaminants to improve safety and taste. A water softener, on the other hand, is designed to remove minerals like calcium and magnesium that cause scale buildup (hard water). They serve different purposes. Some advanced under-sink systems might combine both functions, but they are generally separate solutions.
