Cooking is, without a doubt, one of the oldest art forms the human race has yet conceived and certainly one in which the vast majority of the human race takes some pleasure in. Whether it’s a healthy dietary staple that keeps the eater going through a long day or a delectable treat that may not be the healthiest, the fact is people need to eat, and people prefer to eat certain things. Still, cooking can be an ordeal for, particularly large or complex meals. And, in the case of high output kitchens that need to cook a lot of food in a small amount of time, it can also be a serious fire hazard.
Kitchen hood filters are an essential element of restaurant kitchens across the planet, be they the smallest hole in the wall fast food outlet or the stateliest eatery in town. When cooking large amounts of food very quickly, grease will often take on a gaseous form rather than the liquid form most cooks see in their work. The gaseous grease then finds its way into the ventilation, climate control ducts, fans, kitchen hoods or even the fans that keep the kitchen’s air breathable and safe for human habitation.
While this is a fairly small amount of gaseous grease slipping into the air systems of a building (and in almost all residential kitchens is a total non-factor as too little grease will accumulate), in a commercial kitchen, it can get worse. A little bit of a grease with each meal, combined with serving hundreds of meals a day, can lead to a large accumulation of grease in kitchen exhaust systems. Left uncleaned long enough, these grease build ups become a genuine fire hazard, a flammable material entrenched in a kitchen’s exhaust systems just waiting for the smallest spark to kick start a disaster for any business and possibly the entire community.
One option for fending off these disasters is disposable kitchen hood filters. But what is the case for disposable kitchen hood filters? These are simple filters, similar in principle to ordinary residential furnace filters and the lint catches of ordinary dryers, that are placed over a stove, fryer or other commercial kitchen appliance. As the grease evaporates and flows upwards with the steam generated by the cooking process, the kitchen’s fan sucks the grease towards the hood. The hood’s filter, however, captures the vast majority of the gaseous grease and prevents it from ever making its way into the duct systems. Some grease does evade these filters, but very few filters operate at one hundred percent capacity.
The advantages of these devices are fairly important to any commercial kitchen operator. The main advantage is that any grease that gets lodged in the filter is not lodged in the duct systems. This works out in the kitchen’s favor in some ways. First off, the grease lodged in the filter is easier to remove and tends to present less of a fire hazard if removed from the kitchen’s hood soon enough. Second is that by preventing the build of grease in the duct system by directing it into the filter, it requires that the duct systems be cleaned of greaseless often. This reduces the fire hazards and saves a business money, as any grease trapped in the filter doesn’t need to be paid to be removed. And, given the cost and complexity of removing entrenched grease from a kitchen’s duct work, anything that cuts back on these costs is a good thing. Still, even these filters do need regular replacement if they are to remain safe for use in any kitchen, and should not be overused.
