Ventilation systems of houses have generally improved with today’s advancement of technology. Recently, there have been many extractor fan for bathroom available in the market. They can be installed in kitchens and bathrooms to eliminate odors that are otherwise undesirable to the house. In some cases, they can be attached to filter systems to provide clean air back into the room. In the kitchen, these fans may be installed in extractor hoods with attached skirts to effectively capture rising gases and smoke. This eliminates fumes from lingering on the room after cooking meals. With a different construction and design, they are equally effective in bathrooms to remove odors and improve air circulation.
Ventilation fans are usually made so that they can be fitted in the wall, window, or the ceiling. In most kitchens, they are built above the stoves to effectively remove household fumes. In bathrooms, they are usually installed in holes cut in glass windows. This type of fan is easier to install, as no major construction is needed. The glass panel needs only replacement with a cut hole of the appropriate size. Those fans that are designed to be installed on walls generally take longer to install as a hole has to be cut from concrete, brick or wooden walls. Some are designed to start automatically with the light switch or can be turned on separately.
With the advancement of technology come more sophisticated fans. There used to be a time when consumers did not have any choice but to have noisy ventilation systems that were more detrimental than useful. Recently however, they have been replaced by more silent machines that may not even be noticed due to their silent operation. Aside from those that directly release air outside the house, there are those that feature several filtering systems that remove odor and other harmful contaminants and return clean air back to the room for fresher circulation. These need more maintenance as filters need to be replaced regularly for these types of fans to be continuously effective.
