8 Signs of Media Replacement


When it comes to replacement every application is so different. The manufacturers suggest that you should replace your media about every 3-5 years depending on its application. Due to the fact that every application is different you should check your media often for replacement. We have put together a list of 8 Signs to watch for in media replacement.





As media ages it can start to sag or slump. If you check the media and it is sagging or slumping in the unit that is a huge indicator it needs to replaced. If it is slumping it is not getting the proper amount of airflow and not wetting out properly which is costing you more in energy usage.





We always suggest following media maintenance tips to help prolong the life of your media. One of these tips is to spray your media out Regularly. However, if you are cleaning regularly and you keep getting bad smells that do not disappear it may be time to replace.






Probably one of the most common things we see with older media is scale and particulate buildup. A lot of this buildup comes because of water treatment. If the buildup is getting to a point where it cannot be washed off or is hardening the media it may be time to replace.







As media ages it may become discolored, especially with lots of sun exposure. As it ages and loses its coloring you will probably start seeing some of the other signs. For applications with increased sun exposure you can always consider media coating.







Overtime media may start to shrink especially if exposed to heavily treated water. As media shrinks it will cause your unit to lose efficiency. It will also cause the media to lose in its functionality.









Sometimes we have seen the media start to fall apart after time and the sheets will start to pull away from each other. For these cases it is important to replace.










One of the most common issues we see as media ages is that it will stop saturating correctly. This will diminish your cooling and cause your machines to work harder trying to pull through cool air.










In some extreme situations we see media that is so old it has nearly turned cement. If your media is to this point it is no longer efficient and needs to be replaced as soon as possible.






We hope these signs and tips help as you seek to get the most out of your evaporative cooling experience! Be sure to reach out to us if you have any questions. You can also go to our Media Replacement page which talks even more about replacement and why it is so important.
