If you have a water purifier, it’s essential to know how often to change reverse osmosis filters?
Depending on your water quality, the system may need a replacement filter after a few months or every year.
RO filters remove salts and various impurities from the water, making it safe for drinking and cooking.
To get safe and pure water quality, follow the manufacturer’s instructions while changing the RO filters.
In this blog post, we’ll provide some tips on extending the life of your filters. Keep reading for more information!
How often to change reverse osmosis filters?
Pre Sediment Filter
A pre sediment filter can trap sediments like dirt, rust, and sand in the water.
You can extend the life of these filters by running cold water right after you turn off your faucet.
Change every 6-12 months or more frequently if your water is hard or you live in an area with high sediment levels.
Pre Carbon Filter
Reverse osmosis systems use a pre-carbon filter to trap chlorine and organic compounds in the water.
Prolonged use of filters can slow your RO system, so you need to change it on time.
Change every 6-12 months or more frequently if you have a large household with many users or if the water in your area contains a lot of organic compounds.
Reverse Osmosis Membrane
RO membranes are the last step in the filtering process. If your membrane is damaged, you should change it immediately.
Change every 24 months or more frequently if the water in your area contains high levels of sediment, chlorine, or total dissolved solids.
Post Carbon Filter
Post carbon filters trap any remaining impurities in reverse osmosis water. If your carbon filter is damaged at all, you should change it right away.
Change every 6-12 months or more frequently if you have a large water requirement or if the water in your area contains a lot of organic compounds.
Signs Your RO Water Filter Isn’t Working.
It’s essential to keep your reverse osmosis water filter clean, or you may find that you are drinking water full of contaminants.
Here are a few signs that your filters need to be changed:
- Your water does not taste as fresh.
- There is a leak at the RO filter housing or connections.
- Your water pressure has decreased.
- You notice a black substance building up on your dishes after washing them.
- The filters themselves are damaged or cracked.
- You also might notice that the purified water coming out of your RO faucet runs through a darker color, which can affect how clear your coffee, tea, and other beverages look.
- If you’ve noticed that the tastes of your drinks are lacking or that there is a noticeable difference in the clarity of your drinks, it may be time to replace your reverse osmosis filter.
- If you have a high water flow, you might need to change your filters more often than recommended.
- You should always change your RO filters as recommended by the manufacturer, but if you notice any of these signs, it’s time to change your filters as soon as possible.
These tips should help you extend the life of your RO water filter and maintain clean, tasty TDS-free (total dissolved solids) water all the time.
How to Change Reverse Osmosis Filters
Step 1. Turn off your water supply and unplug the water purification system if it has a plug.
Step 2. Turn off the cold water valve that supplies water to your water treatment system.
Step 3. Release water pressure from the line by turning on the faucet and allowing water to drain out until it runs clear or there are no more air bubbles in the bar, which could take up to five minutes.
Step 4. Detach the filter housing from where it connects to your water softener by unscrewing the nuts.
Step 5. Remove the old filter cartridge and replace it with new ones by pushing it into place firmly until they click, which means it is locked in.
Wash your hands with soap and clean water after you handle any of your carbon filters or tubing to avoid getting germs on the components of your RO system that touch the water.
Step 6. Please turn on your reverse osmosis system water supply and drain out any trapped air in the system by running it for a few minutes.
Step 7. Turn on your cold water valve and the RO system to ensure that everything is working correctly.
Step 8. Run a couple of pitchers of filtered water through your water purification system to flush out any leftover impurities.
Step 9. Test the pure water coming from your tap to ensure that it tastes and smells clean.
I hope you know the right way to change your reverse osmosis filters.
If your water still has an unpleasant taste, you may need to repeat these steps or call a plumber for assistance.
Reverse Osmosis MEMBRANE Replacement Instructions
1. Turn off the cold water supply and unplug the water treatment system.
2. Locate the membrane housing and remove the housing cap to expose the membrane.
3. Gently pull out the old membrane and replace it with a new one.
4. Replace the membrane housing cap and reattach it to the RO unit.
5. Plug in the RO water softener and recheck the connections.
6. Turn on the reverse osmosis system water supply and check for leaks.
7. Run two or more pitchers of tap water through the system before using it to flush out any remaining particles in the membrane storage tank.
If you are still experiencing cloudy water after flushing out your system, you can recharge it with fresh water for optimal function.
FAQs
How long do reverse osmosis systems last?
The lifespan of most RO systems is approximately 10 years, but it can vary depending on how well you maintain it.
Keep in mind that most RO systems are warranted for one to five years, depending on the brand, so if you are experiencing problems with your system, contact the manufacturer for assistance.
What is reverse osmosis slime?
Slime results from the accumulation of microorganisms that live within a reverse osmosis membrane storage tank.
If your purified water looks cloudy, tastes odd, or has a bad odor, slime may be the cause.
It is rare to experience slime in a household water filtration system because of regularly changing your filters.
If you have a large amount of slime in your storage tank, it may be necessary to replace the membrane or use a chemical additive to resolve the problem.
How to tell if the RO membrane is bad?
If you start seeing leaks within your reverse osmosis water supply that tastes odd, it is time to change the membrane filters.
In most cases, the membrane filter slowly becomes less effective as it accumulates microorganisms and debris, which can significantly reduce your RO system’s performance.
If you need replacement membranes more often than usual, then your RO membrane may have reached the end of its lifespan.
Why purge Reverse Osmosis for 24 hours?
Purging the RO unit is done to flush out impurities accumulated within the membrane.
Additionally, purging followed by a water flush will reduce the frequency of changing filters.
You need to purge and flush your RO unit within 24 hours to avoid any problems.
What order do RO filters go in?
Your RO filter requires three stages of a water filtration system, so each water filter should go in a designated order.
The first stage is your pre sediment filter.
The second stage is your post carbon filter, and the final stage is your RO membrane filter.
To ensure optimal performance, of your reverse osmosis filters cartridge, you need to change it in this order.
How much water can an RO system produce?
The RO system water production depends on the model and brand.
However, most RO systems can produce between 35 and 75 gallons per day, which is enough water for a family of four.
Whenever you initially install your RO system, running two or more pitchers of tap water through the system before using the water is essential.
It will flush out any remaining particles in the membrane tank.
Conclusion
If you know how often to change reverse osmosis filters, they are convenient and efficient in reducing the number of contaminants in your drinking water.
If you properly maintain your RO system, it should last 10 years or longer.
Once your system reaches the end of its lifespan, which you will know because the performance declines, it is time to filter replacement.
Also, as you install your RO system, remember to purge and flush the unit within 24 hours.
Doing so will improve the performance of your RO unit and reduce the amount of time that you need to change filters.
If you follow these steps and use quality replacement parts, then your new reverse osmosis system should provide clean drinking water for a long time.
