Pre-filters stop dust, dirt and airborne particles from clogging up your carbon filter and reducing the airflow through it.
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 experiencing any down time.
These fabric 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 extraction system. The pre-filter is, therefore, the first opportunity to remove dust and particulates 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 extraction 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, otherwise you'd only make the situation worse. 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.
