The most important role of kitchen ventilation is to remove all the greasy, smoky, steamy, gaseous byproducts that you don't want hanging around in your kitchen. When it comes to the choice of the right range hood, it usually depends on the layout and structure of your kitchen, your local building codes, and your own style preferences.
Many of our new, innovative range hood systems use carbon filters. The carbon filters provide better, cleaner ventilation and may eliminate the need for an air duct that leads outside. In addition, the durability and effectiveness of carbon filters is far superior to that of conventional filters.
One of the many advantages of range hoods is the ease of assembly. Many of our range hoods have a telescopic chimney, which allows more freedom for adjustments to the placement of the cooker hoods. Our new range hood chimneys are also easier to bypass through rough walls, which makes installation faster and easier.
Why need a range hood?
There are many safety reasons for not trying to install or build range hoods systems. First of all, range hoods are in place to make sure that you direct dangerous fumes away from the rest of your home. cooktop hoods
are also in place to help keep steam and smoke out of your kitchen as well as prevent smells from moving all around your home. If you don't have a range hood in your home, you can set yourself up for dangerous fires too if the heat should become too high on your range.
The continued presence of cooking fats, grease, steam and odors are an ongoing problem in every kitchen. Every year, an average of 4-1/2 liters (1 gallon) of cooking fat deposits itself on the cooler surfaces of walls, ceilings and cupboards. These deposits condense and cause discoloration and dulling of paintwork.
Range hoods filter out the kitchen grease saving you hours of cleaning, extending the time between repainting and giving you a cleaner, fresher kitchen, as well as protecting and adding to the value of your home.
Selecting the right range hood:
The efficiency/extraction rate of the range hood is measured by the volume of air passed through the hood. The measurement is cubic-feet per minute (CFM = ft^3/m).
To ensure that the range hoods meet your cooking requirements, the following needs to be considered:
- As a rule, the air should be changed in a kitchen 12 times per 60 minutes.
- Multiply the floor area in square feet and the height of the kitchen in feet (result: ft^3).
Divide the extraction rate (Extraction Rate = CFM of the hood x 60 minutes) by the calculated figure from above. As an absolute minimum the rate should be in excess of 7 times per 60 minutes.
Types of range hoods:
There are three general types of ready-to-install range hoods: the island mount range hood, the wall mount range hood and the under cabinet range hood. Within this sub-topic we'll briefly examine each of the three types while also discussing some optional features.
Island mount range hoods: This type of range hood often accompanies a downdraft in which attachment to an exterior wall isn't an option. In many cases a retractable intake device is raised from the range or counter in order to pull air into exhaust ducts set below floor level. The ability to retract the range hoods and the sleek nature of many island mount range hood models makes these models more stylish than many under-cabinet models. Shown SV218Z2-I36/I42.

Wall mount range hoods: Large, stylish and professional in appearance, wall mount range hoods continue to gain popularity among homeowners. Often used on exterior walls when a cabinet isn't available, a range hood with a wall mount resembles an upside-down chimney in appearance. Stainless steel finishes are common on wall mount range hoods. A range hood wall mount model is considered the most stylish of the three types. The wall mount range hood model shown here is SV218D-30/36. View our entire collection of wall mount range hoods.
Under-cabinet range hoods: Traditional and usually the least expensive type of range hood, under-cabinet range hoods are, in fact, usually mounted under a wall cabinet and attached to an exterior wall. In many models, air is pulled out of the kitchen through an exhaust duct in the exterior wall. As a general rule, under-cabinet models aren't decorative or trendy.

Ducted or re-circulating ductless range hoods:
When you install range hoods, they can be either ducted to the outside or set up to recirculate the air within the kitchen. With the ductless range hood recirculation option, most of the grease and smells should be trapped by a special carbon filter. Moist air will still contribute to condensation problems and some smells may escape with a ductless range hood. However, with external ducting, the process of removing a lot of hot air quickly does mean the room gets a little cooler. Most of our products do however feature range hood vents or ducts. To convert to a ductless range hood, simply purchase our optional re-circulating kit.
Size of range hoods:
With two pots on your cooktop, most hoods will cope pretty well, and won't let steam escape at the sides. However, most models won't cope very well with four pots of simmering water, particularly if they're only 30-in wide. The bigger the range hood, the more effective it will be at removing steam and odors. If you have the space, consider fitting a 36-in wide range hood over a 30-in cooktop. The extra width on each side will catch more steam.
Range hoods filters:
All range hoods have a filter to trap oil and grease from cooking. Most have reusable, metal mesh filters that will go in the dishwasher. Because the filters are quite large they are not easy to wash in a standard sink.
Range hoods' Fans:
Efficiency is not necessarily related to the number of fans. Some larger single-fan models can out-perform smaller two-fan models.
Fans can be quite noisy on full speed, and there's a tendency for noise to increase with performance. A range of fan speeds is therefore useful: you don't need the thing whooshing away if you're just scrambling some eggs. Noise levels can get up to 60 or even 66 decibels (dBA).
Range Hood Lighting:
A good range hood will provide enough light over the cooktop for you to see into the pots. Many models use only a single 40 watt bulb, which many cooks won't find adequate. Others use two bulbs, sometimes suffusing them with a perspex strip. Many of the more expensive range hoods provide much better light with halogen lamps with dimming options or suffused fluorescent bulbs.
Range hoods maintenance:
Range hoods are not maintenance-free. You need to remove and wash the filter, clean the body of the range hood and occasionally change a light bulb. You should be able to perform most of these tasks easily.
Range hoods controls:
It's pretty standard for hoods to have their controls in an easy-access position on the front. However, some older models have sliding switches that are a little tricky to set in the right position. Touch controls are easier to use and all of our range hoods uses touch controls.
Range Hoods Maintenance:
Wipe the exterior and interior of the range hood regularly. When you need to give it a thorough scrub, use a solution of hot water, dishwashing detergent, and ammonia to cut the grease; wear rubber gloves.
Clean metal mesh filters when they are dirty, and replace the filters on non-vented range hoods every six to nine months or as often as the manufacturer recommends. For more detailed instructions, please see Maintenance section of the User's Guide.
- Exterior cleaning:
Clean your kitchen stove hood periodically with hot soapy water and clean cotton cloth. DO NOT use corrosive or abrasive detergent (e.g. Comet Power Scruv®, EZ-Off® oven cleaner), or steel wool/scoring pads, which will scratch and damage the stainless steel surface. For heavier soil use liquid degrease such as “Forumla 409®” or “Fantastic®” brand cleaner.
- Interior cleaning:
Warning! Be sure the unit is turned off before you clean it. Also avoid spraying cleaner directly onto the light bulb or light bulb socket. Clean the interior of the range hood with a standard household degreaser/cleaner.
- Fan motor care:
Most kitchen hood exhaust fan motors don't need any maintenance. Over time, the motor and bearings may become stiff because of the constant heat, humidity, and grease to which they're exposed. Also over time, the blower wheel gets greasy and dirty, which can slow down the fan or cause vibration. Remove the wheel and clean it with a degreaser. Then, if the fan is still slow or if it vibrates, you need to replace the fan motor.
- Cleaning the grease trap/cup:
You can clean the grease trap/cup in your range hood by soaking it in a degreasing solution until all the grease is dissolved and then washing it with warm, soapy water.
- Charcoal filters:
If your unit contains charcoal filters, these will need to be replaced. They cannot be cleaned.
Use of the range hood:
- Turn on the range hood before turning on the gas range.
- Both motors must be turned on when the range is set at high heat for stir-frying.
- When decocting Chinese medicinal herbs, make the range hood operate at a lower speed for 3-5 minutes every hour to prevent the plastic lamp covers and oil cup from softening and deforming.
- After cooking, keep the range hood rotating for 3-5 minutes before turning it off.
