Frequently Asked Questions (FAQ)
Which under sink water filter is best?
This is a difficult question to answer, since many factors have to be considered. For instance, how long has the company been around? What sort of contaminants do you want to remove? What contaminants does your city have a problem with? What brand of water filtration system works best in your under sink space?
In general, we will attempt to answer this question with a recommendation based on the best under sink water filter system for the average American home. In the end, there are a few brands that consistently receive good reviews, but for many people the best under sink water filter hasn't been invented yet.
Are under sink water filters worth it?
An under sink water filter is a great investment for reducing your exposure to contaminants in your tap water. While municipal water systems have dramatically improved over the last decade, they still occasionally find contaminant levels that err on the side of the cautionary side. If this is the case for you, then you’ll definitely want to consider a filter for your under sink water supply.
How do I choose an under sink water filter?
Choosing the right filter depends on your specific needs. Water filters can be very helpful if you buy bottled water or if you live in an area with suspected contamination. However, if you live where the water is reliably pure (i.e., you have a well that is tested and deemed safe by EPA standards), there’s no immediate need to filter your water.
Under sink filters are a great way to save money and achieve water purity simutaneously. An under sink filter is a bit more involved than your typical pitcher. It’s attached to your faucets by a water line, and it can require quite a bit of work to install correctly.
However, installing the filter does give you the advantage of being able to remove it and relocate the filter as you wish. That is something you can't do your pitcher, for example, since every pitcher is mounted to the faucet and that is permanently installed.
How long do under sink water filters last?
Regrettably, there is no hard and fast rule. Unlike what you may think, water filters are not suppose to last one year or two or five. It's more of just a rule of thumb given by the manufacturer that the average appliance or filter should last anywhere between 5,000-50,000 gallons. For us, it's difficult to rely on that kind of guidance without first seeing real world figures for ourselves. Despite the lack of real facts, there are a couple of things that can help us understand when it's time to replace the filter:
If you use a whole house filter, the sediment or carbon block it contains will be more likely to fail, as these are large and often have a very short lifespan.
If you purchased a pitcher-style filter, the filter itself is the only part likely to fail, and sometimes those can last for several years.
Conclusion
We are huge proponents of buying local and drinking local. When you drink locally, you enjoy better quality and a wider selection of products. We’ve also noticed there is an undeniable link between pure water and pure taste. There is no need to get all poetic about it – just use this guide to select and install the perfect faucet mount water filter for application at your sink. These will help keep your water on tap healthy and tasty.
