Well water filters need constant monitoring since well water is prone to heavy contamination.
Depending on the quality of your well water, you may need to change your filter more or less frequently.
We’ll go over how often to change a well water filter and when the best time to do so is.
The replacement schedule of a well water filter varies depending on several factors, but a good rule of thumb is to check your manufacturer’s recommendations.
Generally, a whole house well water filter must be changed every 3 to 12 months.
There are three primary factors that affect how often you need to replace your well water filter: the quality of your well water, the type of filter you’re using, and how much water you use.
Each type of whole house well water filter has a different lifespan. Some filters last only a few months, while others can last up to a year plus. Here is a rundown of the different filters and their average lifespans:
This is the most common type of filter used in well water systems. They remove particulates like sand, dirt, and rust from your water. Depending on the quality of your well water, sediment filters will need to be replaced every 3 to 12 months.
Iron filters can last up to 12 months depending on the amount of ferrous iron dissolved in your water. Besides, this filter type can also trap manganese and sulfur.
Activated carbon filters remove chlorine, chemicals, and other contaminants from your water. These filters typically need to be replaced around every 12 months.
KDF filters use redox reactions to remove stuff like heavy metals from your water – think lead. They also prevent the growth of bacteria. KDF filters usually last about 1 (2) year.
Reverse osmosis systems work by forcing water through a semipermeable membrane, leaving any contaminants behind. They often deploy multiple filter stages that have different replacement schedules.
UV light filters use ultraviolet light to kill bacteria and viruses in your water. UV bulbs typically need to be replaced every 12 months.
This type of filter uses a very fine membrane to remove even the tiniest of contaminants. On average, these filters last 6 months to 2 years.
While there are recommended replacement schedules for every filter, your overall well water quality can influence the lifespan, too.
Water quality is determined by the concentration of contaminants and other impurities in the water. If your water quality is exceptionally poor, you may need to replace your filters earlier than recommended.
If you have made any recent repairs or changes to your well, your water quality may be affected. Sediment or other materials may have seeped in during work, so it’s important to have your well flushed and/or tested afterwards.
If you have a pressure tank that stores your well water, it will eventually need to be replaced.
During the replacement process, there’s a chance for debris ending up in your plumbing system. This debris will likely cause your well water filter to clog quicker than normal.
Drought can cause your well water to become more concentrated with contaminants since there’s less water to dilute them. On the other hand, rainwater can wash new contaminants into your well. The Environmental Protection Agency (EPA) recommends having your water tested immediately after natural occurrences like these.
The amount of water you use also affects how often your filter needs to be replaced. If you live in a house with multiple people and have high water usage, your filter will need to be replaced more frequently.
Technically speaking, there are no filters that don’t need at least some form of replacement. Even if you have a well water filter advertised as “maintenance-free,” it will still need some level of regular care.
The good news is that there are well water filters that can last several years before their lifespan ends, like carbon-based filters using large tanks.
If you wait too long before changing your whole house well water filter, you could start to see some consequences throughout your home.
Yes, it’s possible to change a well water filter by yourself. Your manufacturer’s manual usually provides instructions on how to replace water filters, so it’s important to follow these to avoid any damage to the system.
That being said, if you’re not comfortable changing the filter on your own, you can always hire a professional to do it for you.
Changing a home well water filter is a lot simpler than it sounds.
And that’s it! You’ve successfully changed your well water filter.
Water filters that have not been used often have no expiry. However, if you used a water filter once and left it unused for a long time, contaminants may have already accumulated in the filter. This is why it’s important to change it even when you haven’t used it for a while.
Aside from the recommended schedule, several physical signs indicate when your well water filter needs to be changed.
