So let’s say that the water supplied at your household was of a low quality and you decided to install a filtration system. Now both you and your family are happy with the new water provided that tastes great and has beneficial properties for your body, health and even plants or house appliances. Yet, over the time you see a slight change in your water which might include noticing sediment, discoloration or funny taste. To prevent the latter it is important to know that in order to enjoy your filtered water simply installing a filtration system is not enough as it requires frequent maintenance. By this we refer to changing the essential part of your water cleaning system – filter. But how do you know when it is time to change your filter and how long does a water filter last?
On average a water filter lasts up to 6 months. However, the exact lifespan depends on a filtration system you own, primary water condition, and the amount of water that has been filtered. Also, take into consideration the type of your system as pitcher or under sink filters will need a rather frequent change (every 3-6 months) than a whole house one (every 6-12 months).
To be sure that your filters are being changed on time keep notice of the information provided by the manufacturer as every water cleaning system has different lifespan that depend on different factors which determine the exact period eligible for your filter specifically. Take a look at an estimate filter lifespan depending on its type:
|Filtration system||How often do you need to change its filter|
|Whole house system||6-12 months|
|Pitcher Cartridge||4 weeks|
|Under Sink system||3-9 months|
|Shower||6 months (every 10k gal)|
|Fish Tank Cartridge||4-6 months (for 10gal tank)|
How Often to Change Whole House Water Filters
Whole house water filters need to be changed every 6 to 12 months. However, most of the whole house water filtration systems have several stages of filtration. Therefore, each of these stages have its own separate filter that has to be changed accordingly. In short, a pre-filter (the one that collects larger particles) has to be changed every 3-6 months, a carbon filter (if present) lasts for 12 months and a post-filter (which concludes a cleaning process) also has the lifespan of one year. Of course there are other options on the market that would need less maintenance throughout the year. For example, Reverse Osmosis systems are a great option if you are seeking for perfect quality water and less care. Whole house RO system would provide you with 99,9% clean water and would require to change all of its filters (except the membrane) once a year to ensure the maximum effectiveness.
How Often to Replace Pitcher Cartridge
Ideally a pitcher cartridge has to be replaced every 4 weeks. As much as pitcher filters are convenient in their price and availability it comes with a downside of frequent maintenance. Pitcher filters are a great choice for those who have to make an on-the-spot decision to clean their drinking water, yet not a great choice for a long term use. Although cartridges clean your water effectively from contaminants like zinc, copper and unpleasant tastes its lifespan is very short due to their primitive mechanic way of operation.
How Often to Replace Under Sink Water Filters
Normally under sink water filters have to be replaced every 3-9 months. However, the actual lifespan of a filter is very much dependent on the pollution level of unfiltered water at your household. These types of filtration systems are a great choice for those who need high quality water supply locally in their house, e.g. kitchen. Under sink water systems are highly effective and require low maintenance due to their technological advantages. If you are considering installing an Reverse Osmosis system then keep in mind that you can also have an under sink RO system as well as the whole house one.
How Often to Replace Refrigerator Water Filters
Depending on the manufacturer, refrigerator water filters need to be changed every 6 months. Having a water filter or ice maker installed within a refrigerator is a very convenient feature chosen by most families. However, because this feature is usually used daily the filters that provide you clear water and ice have to be cared for. Changing refrigerator filters at least twice a year will ensure to remove any impurities, contaminants or tastes and odors from the water it supplies.
How Often to Change Shower Water Filters
On average shower water filters have to be replaced every 6 months or every 10.000 gallons of water. This average has been estimated counting the amounts of a daily use of shower water of a family of four. Shower filters are very important to maintain since they protect your skin from toxic contaminants like chlorine and heavy metals that would damage it and cause dryness. Moreover, untreated shower water would also negatively affect your hair as it would be more prone to dryness, loss of shine and discoloration.
How often to change Fish Tank Cartridge
Fish tank cartridges have to be replaced every 4-6 months for a 10 gallon tank. Therefore, the exact lifespan of a fish tank cartridge depends on the size of your aquarium. An easy way to identify whether a filter cartridge needs to be changed is to notice water flow – once it is decreased you have to change the cartridge. To prolong the lifespan of your fish tank cartridge consider using RO water which is ideal solution for a fish tank. Because Reverse Osmosis water is completely pure it will decrease workload for your cartridge extending its effectiveness for a longer time.
Factors that Influence the Need of Water Filter Replacement
The lifespan of your filter or cartridge depends on many uncontrolled factors. Learn what they are in order to manage your water systems work effectively:
Type of filter
The lifespan of a filter directly depends on its type. That is because certain types of filters are designed for certain tasks. So when you have a filter for a whole house system it is made in a way to deal with large amounts of water when on the other hand a pitcher cartridge has a rather primitive design for a quick water cleaning solution in small amounts.
Type of water
Different filters are made to deal with certain contaminants and only to some extent. Therefore, if your water is more polluted your filter has to deal with removing more substances and in larger amounts hence, decreasing its effective lifespan.
The more filtered water you use the more workload your filter has. As every filter has an estimated amount of gallons of water that it can filter, once it reaches its maximum filtration scope it loses effectiveness. Therefore, when using filtered water in large amounts it may reduce the lifespan of your filter.
Depending on the area you live in your water might have more sediment than normal. Filtering out sediment is very hard for your filter and in some cases might simply clog it. If you are aware of the presence of sediment in your water consider using a pre-filter or any other methods to treat the sediment first and then give the rest of the job to your regular filter. Some systems like RO have sensitive membranes that would be easily damaged by the sediment resulting in a failure of the whole water system.
