The frequency of replacing your whole house water filter depends on a few factors: the type of filter you have, how much water is used in your home, and the quality of the incoming water supply. Generally, a whole house water filter should be replaced at least every six months or more frequently, depending on your usage. If you have a high sediment filter, it should be replaced more often depending on the amount of debris in your water. Additionally, if you notice any changes in your water quality or pressure, this may indicate that it’s time to replace your whole house filter. Regular maintenance and replacement will ensure the system is working properly and provide your family with clean, filtered water.
What Is A Whole House Water Filtration System?
A whole house water filtration system, also referred to as a point-of-entry (POE) filter, is a complete filtration solution for the incoming water supply of your entire home. It is installed at the source of your water supply before it reaches any other fixtures or appliances, ensuring that all the water used in your home is filtered. This type of system offers more comprehensive filtration than a standard point-of-use (POU) filter, which typically only filters the water used for drinking and cooking.
Why Filters Need To Be Changed?
It is important to frequently change your whole house water filter since filters can become blocked with sediment, rust, and other debris over time. If the filter is not changed regularly, it will lead to decreased water flow and pressure issues in your home. In addition, if you have a carbon-based filter, the carbon itself will break down, decreasing its ability to filter out contaminants in your water.
How Often Should I Change My Whole House Water Filter?
The frequency of changing your whole house water filter will depend on several factors. These include the type of filter you use, the quality and quantity of sediment in your water source, and your usage patterns. Generally, most filtration systems should be changed every three to six months.
- Pre-filter: Every 3 to 9 months: If you are using a pre-filter to protect the primary filter, it should be changed more often than the main filter. This will help catch finer particles and extend the life of your main filter.
- Post-filter: Every 6 to 12 months: It’s best to replace your post-filter cartridges every 6 to 12 months. Even if you don’t see any visible signs that the filter is clogged or is working less effectively, contaminants can still be present in your water supply and could impact the taste or texture of your water.
- Filtration tanks: Every 5 to 10 years: Filtration tanks are the most commonly used type of whole-house water filter. They have a life expectancy of 5 to 10 years and must be replaced regularly. The frequency at which they should be changed will depend on the quality of your water and how often the filter is being used. If you experience any decreased water flow in your home, this could be a sign that the filter’s capacity has been reached and it needs to be changed.
- UV filter (lamp): As needed (about once a year): Depending on your usage and how often you check the filter, replacing your UV lamp once a year is a good idea. This is especially important if you have hard water or other contaminants in your water supply. A dirty UV lamp won’t be effective at killing off bacteria and viruses, so make sure to change it annually.
- Salt-free water softener filtration tank: Every 6 years: It is recommended to replace the water softener tank every 6 years to reduce the chance of contaminants or other particles being released into your drinking water.
How Often Should You Change Water Filter Cartridge?
The rule of thumb is to change your filter cartridge every 6-12 months or when the manufacturer’s instructions suggest. This can vary depending on the type and size of your filter system and how much water you use in a given amount of time. Generally speaking, most whole-house water filtration systems will need to be changed sooner if they are used more frequently or have higher water flow rates. Some systems may require you to change their filters as often as every 3 months to keep the system running smoothly and efficiently.
How Often To Change Big Blue Water Filter Cartridge?
The frequency of filter changes for a Big Blue Whole House Water Filter can vary depending on the filtration needs of your home. The most common recommendation is to change the filters every 6-12 months, but this may need to be adjusted depending on water quality and usage. For example, if your water has high sediment or iron levels, you may need to change the filters more frequently.
It can also be beneficial to install a sediment pre-filter before your Big Blue filter. This will help reduce the frequency of filter changes and keep your system operating at its best. If you have a sediment pre-filter, we recommend changing it every 3-6 months to maintain optimal filtration performance.
Factors That Influence How Long A Whole House Filter Lasts
- Filter Type and Material: Different types of whole house filters use different filtration media to capture impurities from the water. The type and material used in a filter can have an impact on how long it lasts. For example, some filters use a ceramic or pleated polyester material designed to be durable and last longer than other materials like activated carbon which doesn’t last as long.
- Filter Capacity: The larger the filter capacity, the longer it will last before needing to be replaced since it will have more effective filtration media. When choosing a filter, consider the size of your home and how much water you use daily to determine what capacity is best for you.
