MEASURE UP size of your bathroom
Every home has a different size of the bathroom room, and the first thing that you need to do is to measure up the bathroom room. if you have a large-sized bathroom, then you need a large size bathroom fan with a higher CFM rate, but if you have a small bathroom, then a standard bathroom fan with average CFM rate can be good enough for you.
Measuring the height of the bathroom is essential because some bathrooms have higher ceilings than the common standard bathroom, and this type of bathroom require powerful exhaust fans.
Exhaust fans come with individual specifications, and if that specification doesn’t meet your requirements, then the fan will not benefit you. Make sure that the fan you are going to buy should be suitable to the size of your bathroom.
Another aspect to be considered regarding the purchase of the best exhaust fan is the intensity of the sound of the fan.
The noise or sound of the fan is very irritating in the bathroom that upset the peace of mind of the user in the bathroom. There can be no soundless fan, but you can buy the fan that produces minimum sound in its operation.
The sound rating is measured in sones. The lower sones level means less sound produced by the fan, and higher sones level means more sound produced by the fan.
Always read the specification for knowing about the sones rate of the exhaust fan and only choose that fan which features fewer sones rate because fan with fewer sones rate will not produce irritating sound during operation and you will have your bathroom well-ventilated without the annoying sound of the fan. Whisper fans and brushless fan are often quieter than other exhaust fans.
Energy ratings mean the energy consumed by your exhaust fan during its run. Some fans consume more energy than others. There is the wrong assumption that a larger fan consumes more energy than a smaller fan. It is not a fact.Therefore always read the specification of the fan where you can read about energy rating of the fan so if you want to save your money, choose the fan that consumes less energy and does not increase your electricity bill.
Knowing about the size of the bathroom and an exhaust fan that you want to install is very important. you should be certain that you have enough proper space in your bathroom for the installation of the exhaust fan.
Sometimes you have to cut the tile or remove the whole tile for installation of the fan, and sometimes you are just replacing the old fan with a new one.
Whatever your situation is, keep it in your mind before buying the exhaust fan. Always choose the fan that fits best and performs good enough ventilation.
There are two types of exhaust fans. The wall mounting fans and ceiling fans. You should choose the one that fits well in your bathroom.
You should only choose that option that provides optimum ventilation to your bathroom because the purpose of both types of fans is the ventilation.
Durability is a feature that you seek in every product as naturally, you want a good return of your bucks. If the product that you purchase don’t last long, it would be useless. You can’t afford to replace such a thing again and again.
The durability of the product is also connected with the performance of the product. Obviously, If the quality of the product is not good, the performance of the product cant be good enough.
The durability of the exhaust fan is very important because there is a complicated process of replacing and installation of exhaust fan which cant be afforded after the short period of time.
