If you regularly use carbon filters you will know that when they reach their capacity they will stop working efficiently. With this in mind, it is important that you change your filters before they get to this point to ensure that they continue to cleanse the air of potentially harmful as they should. Here, we take a look at how often your carbon filter needs changing so that you know what to look out for.

What is the lifetime of a filter?

Unfortunately, there is no exact science when it comes to working out the lifetime of an air filter. This is because it will depend on how often its used and they type of contaminants that it’s filtering. If your filter works around the clock in a laboratory that is prone to airborne particles it will have a much shorter lifespan than one that is only used every so often. The best thing to do is to consult the manufacturer’s guidelines for your particular filter as these will give you an idea about how long you can leave it before it needs changing.

Will a pre-filter extend a filter’s lifetime?

Pre-filters can help to extend the lifetime of an air filter as they work to trap larger particles before they can enter the main filter. These particles could otherwise saturate your main filter quite quickly which would shorten its lifespan. Pre-filters work best with carbon and HEPA filters, so you might like to invest if you have one of these filters as it could save you money in the long run.

Now you know how often your filter need changing you can look after it correctly. Should you need an engineer to check or replace your filter for you, please contact us and we’ll be happy to help.
