Common Mistakes That Reduce Water Filter Lifespan

Common Mistakes That Reduce Water Filter Lifespan
Maintaining and preserving your filtration and osmosis system, and keeping it in good working order is essential for healthy and efficient output.
However, many gardeners, from beginners to seasoned growers, make minor mistakes that substantially reduce the lifespan of their filters. Here are the most common mistakes and how to avoid them…
1. Not changing filters on time
This is by far the most common mistake growers will make. Each type of filter (sediment, activated carbon, osmosis membrane) has a specific lifespan. Using them beyond their capacity can reduce flow, contaminate the treated water, and even damage the entire system.
Recommendation: Create a maintenance schedule and regularly check the status of each filter.
GrowMax Advice: How often your filters should be changed is dependant on the number of litres filtered. [See Table 1]
(However, please note that water quality varies greatly from one area to another — therefore sometimes these guidelines apply, and other times the filters and membranes may last longer or shorter.)
For this reason, we usually recommend changing the pre-filtration (sediment and carbon filters) every 4 to 6 months, and the membranes every 1 to 1.5 years. Membrane lifespan will be much longer if the pre-filtration is replaced regularly, because the activated carbon protects the membrane from chlorine, which is its number one enemy.
2. Insufficient pressure in the system
Both excessively low and excessively high pressure can have an impact on the performance and lifespan of filters, particularly the osmotic membrane.
Recommendation: Check that the pressure is within the recommended ranges, and use a pressure pump as needed.
3. Incorrect storage and handling
If you store filters in humid or contaminant-prone areas before installing them, you risk damaging their integrity even before they are used.
Recommendation: Keep spare parts in dry, clean places with moderate temperatures.
4. Failure to periodically disinfect the system
Bacteria and biofilm can accumulate in the system after prolonged inactivity.
Solution: Use specialized disinfectants every 6-12 months or when the membrane is replaced.
GrowMax Pro Tip: Cleaning products containing H₂O₂ (hydrogen peroxide) are the most suitable for disinfecting reverse osmosis systems. It’s generally recommended to use hydrogen peroxide at concentrations between 3% and a maximum of 10%.
You can use products such as Silver Bullet Mist and Growth Technology Liquid Oxygen, but we suggest lowering the concentration to around 3%, not exceeding 5%. It’s better to clean the system every 6 months with a lower concentration than to do a very intense clean once a year.
