Cooker hoods containing extractor fans and filters are very popular and do a great job in keeping the kitchen from steaming up. However, the filters through which the steam is extracted can become very clogged up with fat, grease, dust and dirt, and can become a fire-risk if blocked. The metal mesh filters in cooker hoods are designed to be cleaned and reused, unlike carbon or plastic filters, and the Mesh Filter Cleaner is designed to make cleaning them easy! Clean filters mean that your cooker hood works much more efficiently, and it is recommended that they are cleaned every month.
