Every range hood relies on its filters. Mesh filters, layers of fine aluminum or steel screen, trap grease droplets in their weave; baffle filters, folded steel channels, force the air to turn sharply so the grease is thrown out of the stream and runs to a collection channel. On a recirculating hood, a charcoal filter behind them soaks up the smell before the air returns to the kitchen. When these fill up, everything else suffers: the hood pulls less, the blower works harder and runs hotter, grease begins to condense inside the body and drip back onto the burners, and a flame flaring from a pan can find fuel waiting above it. This service is more than a wash. Filters are inspected for bent frames, torn mesh and loose clips that let air bypass them; baffles and mesh are degreased, dried and refitted; charcoal pads are replaced with the correct size; and the grease channel, the drip cup and the underside of the canopy are cleaned. Where the hood has a filter reminder, it is reset. If the buildup has already reached the blower wheel or the duct, the visit says so and names the next step. How the visit goes ### What it usually costs Lowest · Mesh or baffle filters, charcoal pads and the grease channel Cleaning and refitting the filters with a new set of charcoal pads is the smallest job on this page.

In a kitchen that cooks most days, about once a month, and every couple of weeks if you fry or sear often. Soak mesh or baffles in hot water with a degreasing dish soap, rinse and let them dry fully. Many steel baffles can also go through a dishwasher; check the maker's note first. ### Are baffle filters better than mesh ones? They catch grease differently. Baffles are sturdier, keep their airflow as they load and clean up easily, which is why pro-style hoods use them. Mesh filters are lighter and catch finer droplets but clog sooner. The best choice is the type your hood was built for, kept clean. ### Does a hood with dirty filters really raise the fire risk? Yes. Grease that the filters and the hood body hold is fuel sitting right above the burners, and a flare from a pan can reach it. Clean filters are one of the simplest ways to keep a kitchen safer. If grease has built up inside the hood body or the duct, that deeper cleaning is worth booking. --- **[Read on the site: Range Hood Filter and Baffle Service](https://rangehooderepair.center/services/range-hood-filter-and-baffle-service/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
