Several points for attention when buying range hoods:


1. The suction capacity is usually measured by CFM (cubic feet per minute), usually around 800 CFM is enough. If it is too high, the noise problem must be considered, and a larger pipe must be used. The wall must be opened with a large hole, otherwise it is practical. The effect cannot be exerted, but rather noisy, not necessarily required. If you want to make a hole in the wall, you must install a covered air outlet, otherwise mice and cockroaches may enter the home through this, and the fume is very attractive.


2. Is it quiet enough? This point is considered in conjunction with the previous point.


3. The suction vent is outside, or the fan angle is slightly oblique, and the coverage area is larger, so the effect of absorbing oil fume is better. You can bring your own tape measure to measure it. The United States usually has a four-burner stove, and Asia generally has a second-burner stove. Therefore, a longer range hood is required.


4. Is there a drip tank design? Because American households do not cook vegetables, the range hood does not take into account the oil fume. The oil accumulates in the machine and will stink after a long time. Therefore, whether the range hood has a drip tank and easy to drain oil is a very important consideration. A well-designed smoker The range hood, even after long-term use, if oil accumulates in the body, it will automatically drip to the oil cup.


5. Is it easy to clean, or is there an oil filter design? Each design is different and each has its own advantages and disadvantages. In addition to filtering oil fume, the installation of an oil filter is generally to prevent hot oil from spraying into the body.


6. Range hoods are generally divided into two widths of 30 inches and 36 inches, and the average family is 30 inches. There are 6-inch, 7-inch, 8-inch, and 10-inch air outlet pipes. The normal size is 6 inches. The air outlets that need to be opened to be installed should also be checked first. It is better to have a Wall Cap cover. Use Duct Clamps to clamp the pipe. The hard pipe is more durable than the hose. When installing the pipe, you can use Sealant or Silicone Sealer to seal the inside and outside: the outside can be used for sealing and waterproofing of doors and windows. Before nailing, apply a circle along the cut hole on the outside. After nailing the Wall Cap, apply sealing and waterproofing around the sides. Such as Great Stuff Window and Door Insulating Foam Sealant. The inside can be sealed with DuPont or GE Aluminum & Metal Silicone adhesive to prevent air leakage. Installers like to use Mastic Sealant faster but uglier, and no one sees it inside.
