5 Signs You Need to Replace Your Filter Media

Don’t wait until it’s too late! Find out how to determine the optimal replacement time for your filter media

Changing the filter media at the right moment is imperative in order to maintain a healthy filtration system. You can avoid unnecessary costs and process issues if you always change your media at the right time.

What are the signs that indicate you need to replace your media? Let’s find out:

1. The differential pressure has surpassed 30 PSID

Differential pressure is the best indicator of when it is time to change media. A good rule-of-thumb is to change the media once it reaches a differential pressure of 15-30 PSID. Most filter media have a maximum differential pressure rating indicating the point at which the filter will fail, but the filter should be changed at a far lesser value than the maximum rating.

2. The flow rate has changed drastically

If the flow rate is slower or faster than usual, it may be time to change your filter. A proper filtration system should have a consistent flow rate depending on how fast the filter is clogging. If flow rate drops too low, it can indicate a filter that is plugged and not allowing enough fluid downstream. On the other hand, if flow rate has significantly increased, it can indicate that the filter has failed and is passing contaminants downstream.

3. Too much or little time has passed

Changing your media based on time can be a risk since you could potentially change it out too often or not enough. Changing your filter too often or too early can lead to additional, unnecessary filter media costs; not changing it enough can lead to a build-up of differential pressure, potentially compromising the filter media and allowing contaminants to flow into final product.

It’s strongly recommended that you do not change your media based on time; however, if you do, it is imperative to monitor the differential pressure and flow rate. Changing based on time, alongside monitoring differential pressure and flow rate, is a great back-up method in case anything seems abnormal.

4. The downstream product quality is poor or inconsistent

It may also be time to change your filter if you notice the product has more “dirt” downstream. This means that the filter may be unloading contaminants downstream due to an inconsistent flow rate, high differential pressure or the media has been compromised.

5. The media is damaged upon inspection

If you find the media is damaged or compromised upon inspection, not only could it be an indicator to change your media more often, but you may need a different type of media or filtration system. A damaged or compromised media could mean your filter may not be able to handle the pressure or solids you need it to.
