How Often Should I Change The Rainsoft Water Filter?

Filters should be changed every three to six months for optimal performance and effectiveness. The frequency with which you need to replace your filter depends on various factors, such as the amount of sediment in your tap water, the number of people living in your home, and the type of RainSoft filter you have.

RainSoft water filter systems use a combination of mechanical filtration and activated carbon to remove contaminants from drinking water. The system also eliminates unpleasant tastes, odors, and discoloration caused by chlorine and other chemicals in tap water.

How Often Should I Change The RainSoft Water Filter?

RainSoft recommends changing the filter every six months for optimal performance. However, if you notice a decrease in water pressure or an increase in sediment or chlorine odors from your tap water, it is time to replace your filter. It is also important to remember that filters will need to be replaced sooner in areas with higher levels of sediment or chemical contaminants.

  • For sediment filters: RainSoft sediment filters should be changed every three to six months or when the filter becomes clogged. It is important to inspect your filter regularly, as a clogged filter can reduce water flow and possibly wear out the pump prematurely.

  • Cartridge filter: If your filter is a basic cartridge-style filter, you should change it every two to three months or sooner if the pressure drop becomes noticeable. If your RainSoft system uses a carbon block filter, changing it every six months is better, as the filter will last longer.

Benefits Of Changing Water Filters Regularly

  • Improved water quality: Regularly changing your RainSoft water filter ensures you always consume the cleanest, safest, and most refreshing drinking water. By removing contaminants like chlorine and heavy metals from your tap water, a RainSoft filter can improve the taste of your food and drinks while providing healthier alternatives to store-bought bottled water.
  • Longer lifespan of your filtration system: Depending on how hard or soft the water is in your area, you can expect a relatively long life out of your RainSoft water filter. Generally, the harder the water, the shorter the lifespan.
  • Cost savings in the long run: Changing the RainSoft water filter every six months to one year will cost less in the long run than leaving it for longer periods. This is because contaminants accumulate in the filter over time, leading to clogging and reduced efficiency. Moreover, when a clogged filter is not replaced on time, this can lead to higher energy costs as your system works harder to produce clean water.
  • Environmental benefits: Changing the RainSoft water filter regularly also provides environmental benefits. The filters trap minerals, metals, and other contaminants that can lead to unhealthy drinking water if not removed. Removing these contaminants from your home’s water supply makes it safer for you but also helps keep them from entering waterways where they could create an even greater hazard. Additionally, by changing your filter regularly, you’ll reduce the amount of plastic waste in landfills or polluting oceans, as old filters can be recycled to help lessen their environmental impact.

How To Know When To Change Your RainSoft Water Filter?

  • Changes in water taste or odor: If your water begins to have a different taste or odor than usual, it could indicate that the filter needs changing.
  • Reduced water pressure: If you notice a decrease in water pressure, it may be time to change the filter. The filter will become clogged over time due to sediment and other particles that can reduce flow rates.
  • Visible debris in water: If you can see debris in your water, the filter may need to be changed. Generally, if there is a significant change in the taste or smell of your water, replace the filter as soon as possible.

How To Change Your RainSoft Water Filter?

Tools Needed:

  • Phillips head screwdriver
  • adjustable wrench
  • Rainsoft filter cartridge


Step 1: Shut off the main water supply to your house. The shutoff valve should be near where your RainSoft system is located.

Step 2: Unscrew the sump cover of your RainSoft system by using a Phillips head screwdriver. Place the cover and screws on a flat surface.

Step 3: Unscrew the canister holding your current filter using an adjustable wrench.

Step 4: Remove the used filter cartridge and discard it by local regulations.

Step 5: Install a new RainSoft filter cartridge, reattach the canister to its housing, tighten it with a wrench, and replace the sump cover.

Step 6: Turn on the water supply and run through a faucet until the water is clear again.


What happens if I don’t change my RainSoft water filter regularly?

If you do not regularly change your RainSoft water filter, you may experience a reduction in the quality of your drinking water. As the filter becomes clogged, it will become less effective at removing sediment, chlorine, and other impurities from your water. This can lead to an unpleasant taste and odor and diminished water pressure.

Can I reuse or wash my RainSoft water filter?

No, it would be best if you did not reuse or wash a RainSoft water filter.

Can I use generic replacement filters with my RainSoft filtration system?

No, it would be best not to use generic replacement filters with your RainSoft filtration system. Not only do they lack the same quality and efficacy as RainSoft filters, but using them could also interfere with your filtration system’s performance and void any existing warranties or product guarantees.

Can I change my RainSoft water filter, or do I need a professional?

You can easily change most types of RainSoft water filters yourself. If you have a whole-house water filtration system, however, it is recommended to contact a qualified professional for help with installation or servicing. This is because the larger and more complicated systems require specialized knowledge.


The replacement frequency depends on various factors, such as the type of filter you have, the amount and quality of your water, and how often you use filtered water. It is important to check your filter regularly for signs that it needs to be replaced. If your filter has not been changed in more than one to two years, it is probably time for a new one. Replacing your RainSoft filter regularly ensures you get the cleanest quality water possible and reduces the risk of damage to your plumbing system from clogged filters. With proper maintenance, you can enjoy the benefits of superior water filtration for years to come.
