How often to change a well water filter? This is a very common question. Almost every water filter user has this question on his mind. However, your water type and source determine a lot of it. In this writing, we will only focus on well water. Therefore, customers who have well water supply will hopefully be helped by this.
Moreover, you can go through this amazing book by Bryan Stevens first. Definitely it will help you to make a better choice. I am giving the link: /Are-Really-Going-Drink-That/dp/1463677049/ref=sr_1_3?keywords=water%20filter%20book&qid=1561042430&s=gateway&sr=8-3&fbclid=IwAR3EZ4DSGg7piUnEGzhoyB8v0RIHeD9bG7kBHUmzzPY3N7VvhDnjsFfwpcg
Exogenous factors affect the lifespan of your filter:
Firstly, I would like to mention that well water is very different from city water. This is because well water sources are heavily influenced by exogenous factors like geographical and environmental factors whereas city water is controlled by medicines and chemical treatments. Thus, the process of determining the time to change filters is different.
As I have mentioned before a lot of it depends on the geographical and environmental factors. Now, I will explain how it does. If you are someone from the colder environment or from somewhere it snows to be precise everything will change when winter goes away.
For example, with the arrival of spring, the snow will melt away and let go of the sediments it had absorbed during winter. Of course, these can flow into your water well water and change your water entirely.
In addition, heavy rainfall or drought might change your well water too.
You should not forget that autumn is a momentous time too. During autumn a lot of leaves fall from the tree. Eventually, they turn it to debris and decompose into the soil. Not only leaves, but many organic matters are also decomposing into the soil every minute.
Believe it or not, somehow these are affecting your well water source as well. Therefore, your water is changing from the source. To be precise, the components and pollutants of your water are changing from the source.
What should you do when exogenous factors are affecting your filter?
You will notice, often announcements are spread along with water testing kits by townships and local universities for testing specific contaminants. You should never avoid those tests. Moreover, at least test your water twice a year.
Although if you are an inhabitant of somewhere where there are extreme seasonality swings, you should check your water more than twice a year.
If you see the pollutants of your water has changed, change your filter immediately and find the one that can fight pollutants present in your water.
Does the lifespan of a filter vary with its type?
Of course, there are different timelines for different filters. I will discuss them in detail for you.
Whole house water filter:
If you are using a whole house water filter, you must change the sediment pre-filter within 3 to 6 months. Because this pre-filter, extract most of the rubble. However, you should also check how many gallons or liters you are purifying. In addition, a whole house water filter also sometimes contains Sub-Micron post filters. These filters eliminate minute particles. These filters should be replaced within 9 to 12 months.
Reverse Osmosis water filter:
Commonly, Reverse Osmosis water filters have three stages. Namely; pre-filters, post-filters, and membrane. Among these three, the membrane is the most expensive one. Luckily, one membrane serves well for two years. However, the pre and post filters are usable for six months. Therefore, you should replace them quite frequently.
Under-sink and faucet water filter:
Generally, these filters use two systems. One is reverse osmosis the other is carbon water filter.
If your under sink or faucet filter has a reverse osmosis system, the maintenance will be just as any reverse osmosis water filter. That is you will change the pre and post filters every six months and the membrane will serve you for two years. However, if your system has a carbon water filter, you need to replace it every six months.In addition, you must notice the flow.
Sometimes the water flow decreases even before six months. This might happen if there is too much debris resulting clogs in the pores of your filter. A quick backflush might help you if it is only a clogged issue.
Pitcher water filter:
Pitcher water filter filters work according to the hardness of your water. If your source water is hard then you have to change your filter more than usual. However, if your water has normal hardness, you can expect the pitcher to serve for at least three months to most six months.
Does a filter always serve its given life span?
No, any water filter might serve you for a greater or lesser period of time than it is supposed to. Because the lifespan of the filters, that are prescribed or given by the manufacturers are based on assumptions. To be precise, whatever durability for instance of 3, 6, or 9 months are given by the manufacturers are based on the assumption of the amount of water a household of four might require to purify by this time.
Therefore, if you require filtering your water below the average your filter will last for a greater period than prescribed.
Similarly, if you require filtering water above the average than your filter will last for a lesser period of time than it is prescribed to.
Hence, you must always keep track of the amount of water you are purifying. To illustrate the situation more clearly, let’s assume you bought a whole filter which can filter 100,000 gallons of water and claims to serve you for a year.
However, you have filtered 100,000 gallons of water within eight months. In this situation, your filter will not purify any more water. The vice versa might happen too and your filter might serve you longer than a year.
Last but not least, no matter what filter you are using do not forget to mark the installing dates on your calendar. Be conscious, and enjoy healthy drinking water.
