Many people who own under sink water filter systems know how essential it is to replace filters promptly. But what exactly is the correct time to replace a filter?
There is a lot of information online: often contradictory and sometimes confusing.
The thing is, there are multiple types of under sink water filters. Naturally, each one features different filter cartridge lives. Moreover, other external factors affect filter lifespan as well.
Stay with us as we give you a clear guideline for all types of under sink filtration systems.
Under sink water filters are, perhaps, one of the most popular in-house water filtration systems. They are fuss-free, easy to install, and require little to no maintenance – except filter changes.
Most under sink filters do an excellent job of elevating the taste and smell of your water which is the number one problem associated with drinking water.
What’s more, some good-quality multi-stage filter systems are designed to remove a wide range of impurities, including chlorine, pesticides, VOCs, lead and other heavy metals, and more.
In the same way, advanced reverse osmosis under sink water filters can effectively remove salts like nitrates, bacteria and viruses, chromium 6, and many more nasty contaminants.
As a result, your water is high quality and sparkling, just like it should be.
Here is why we love these nifty appliances:
Under sink water filter cartridges typically last on average six months before needing replacement. However, the time period could vary considerably due to a number of factors. Calculating the exact replacement time for your filters is essential to avoid changing them too soon (useless expense) or too late (dirty water).
The capacity of a water filter is measured in gallons or a set time frame. Typically, strong and large under sink filters can process 500 to 1000 gallons, or 6 to 9 months of water before becoming too clogged.
Since all households use a different amount of water for cooking and drinking every day, the filter’s life also varies based on that.
To put it simply, a household with a bigger family and pets will require more frequent replacements compared to a single-person home.
Similarly, the water quality in every neighborhood is unique. If your water supply is high in sediment, metals, minerals, etc., filters will clog sooner.
On the other hand, the cleaner your water supply is, the more time your under sink water filter will last before giving up.
Filter capacity varies between brands and filter types/models. If you use a generic model from the market with poor quality, you might need more frequent replacements.
Not sure when your under sink filter needs to be replaced? Here are a few giveaways that suggest your cartridge has exceeded its service life.
You may often wonder if you can get away without replacing filter cartridges at the desired time. Or maybe you hate changing your filters repeatedly. But remember: Replacing is not optional – a poor filter is no filter at all!
Replacement filter costs will vary depending on the type and brand of under sink water filter you choose to buy. Thankfully, you can buy them in sets of two or three, which helps save costs.
We always advise using genuine replacements to avoid poor performance. You may also want to look for NSF/ANSI certifications, which ensures you are getting a good worth of your money.
On average, most replacement filter cartridges are priced around $50 to $100 for a set of two or three, including sediment and carbon filters.
Here are a few tips and tricks we have learned over the years:
You see, manufacturers like to believe it’s better to change early than late. But replacement filters are expensive – frugality, all the way!
