No, it is not necessary to use a dryer with a front-load washer. Front-load washers are designed to efficiently remove moisture from clothes during the spin cycle, which means your clothes will come out of the washer less damp compared to traditional top-load washers.
However, whether or not you need to use a dryer depends on your personal preferences and circumstances. If you prefer to have completely dry clothes or if the weather conditions don't allow for air-drying, a dryer can be convenient. It can also be useful for certain types of clothing or fabrics that require specific drying methods.
If you choose not to use a dryer, you can air-dry your clothes by hanging them on a clothesline or using a drying rack. This can help save energy and reduce electricity consumption.
