A clean Can Pre Filter Cloth is an excellent way of extending the life of your Can Filter. Pre filters stop dust, dirt and airborne particles from clogging up your carbon filter and reducing the airflow through it. Get yourself one of these spares and you'll be able to wash the original pre filter without any down time.
Very low air resistance,
Easily changed,
Blocks dust and other particles from entering filter.
Clean pre filters allow for much better airflow in your extraction system
Better airflow means better temperature / humidity control, and faster CO2 replenishment
These fabric Can pre filters fit around your carbon filter. Air is drawn through the fabric, then through the carbon itself and out via the ducting of your system.
The pre filter is, therefore, the first chance to remove dust and particles before they can clog up the carbon. Once dust finds its way inside the filter, it will start to reduce the rate at which air can flow through your system.
Lower airflow rates inevitably make it harder to deal with high temperature and humidity levels. As well as reducing the rate at which CO2 is replaced in the room or tent.
To keep your pre filter clean, you'll need to wash it. Without a spare, you'd need to stop using your extraction system until your pre filter was clean and dry. If you keep a spare, you can swap pre filters over without a problem.
It may seem like a trivial issue, but don't forget that your environment is crucial to the success of your indoor garden. Keeping your extraction system running at 100% is one of those things that will help you to maximise the quantity and quality of your harvest.
