Question

Advantage and disadvantages of mechanical air filters

Answer 1

Mechanical ventilation systems are used in bathrooms, kitchens and sometimes attics to push unwanted air to the exterior of a home. These systems are relatively new to home construction and have their advantages and disadvantages. The modern airtight home requires some fresh air exchanges to keep the living environment healthy for the occupants.



Mechanical bathroom vents are required by the building codes in most municipalities.

What Is Mechanical Ventilation?

Mechanical ventilation is any method of using a power-driven fan to move air in a desired direction. These types of systems are commonly installed in bathrooms, on or near the ceilings, to remove moist air when showering or bathing. Mechanical ventilation systems are also installed above stovetops to remove water vapor, cooking smells and to exhaust the by-products of combustion for gas stoves. They are also installed in attics to increase the amount of air exchange with the outside, reducing moisture buildup and mitigating the chances of mold.

Advantages

Ventilation reduces the amount of moisture in the interior of a home. This moisture comes from people breathing, bathing and sweating, as well as from plants, cooking and stored firewood. As the moisture content of the air rises, the likelihood of mold and fungus taking hold increases as well. If the moisture content of a wooden structure exceeds 18 percent it can begin to deteriorate through rot. Your home needs a much dryer environment than you do, so trying to find the correct humidity is always a balance. Ventilating the house also brings fresher, cleaner air into the living environment. Common household cleaners and products evaporate and can create indoor air pollution.

Disadvantages

The more you ventilate a home the more its heating and cooling efficiency is reduced. When you bring in the exterior air you increase the workload for your HVAC system. However, you can install heat recovery ventilators (HRV) to recover the energy lost through ventilation. Another disadvantage of mechanical ventilators is that they can depressurize a home. The modern home is so airtight that when you force air to the exterior it can lower the interior pressure. This can cause problems for natural vent appliances like furnaces and hot water heaters that need positive pressure to exhaust their combustion products out of the home. The negative pressure pulls these gasses into the living environment and are potentially very dangerous for the occupants.

The Right Balance

As of 2011, engineers and architects are still perfecting the ideal balance between efficiency, ventilation and the health of occupants. When designing an HVAC system, it is best to consult a professional technician to calculate the proper needs of the home.

hey mate here is your answer....


You might have heard many motorcycles sounding different and interesting than the other ones of the same make and model. Sometimes, you see an aftermarket exhaust muffler on these motorcycles, while some of them look similar to the standard model. So, what makes them sound more throaty than the regular motorcycles. The answer is a High Flow Air Filter, which allows more air than your regular air filter. So, let’s know something about these type of filters, their advantages and disadvantages.

An air filter is basically a pleated multi-layered, oil impregnated mesh made from surgical cotton or other fabric. It is used to do the job of cleaning the air going to the intake system of your engine and reduce its turbulence, while restricting the foreign particles (majorly dirt) in that air. So, the internal parts of you engine are kept protected from excessive wear and failure for a longer time. Generally, a filter is selected for an engine on the basis of its displacement and maximum operating speed after calculating the effective filtering area needed. 

Common filters have high obstruction for the foreign particles, which also restricts the flow or air. However, some of the air filter manufacturers (like K&N, S&S, TBR and Screamin’ Eagle) offer special kind of filters that feature better airflow along with superior dirt protection. These type of filters are known as High Flow Air Filters and they offer a lot of advantages as well as some minor disadvantages to your engine, so let’s talk about them.

Advantages of a High Flow Air Filter:

One of its major advantages is performance enhancement of your motorcycle. As a High Flow Air Filter allows more air to enter the engine intake system in a time period compared to your regular filters, the fuel gets more air to burn. It results in a better combustion process that leads to actually increase the maximum power as well as peak torque output of your bike. 

The better combustion process also contributes to a slightly improved fuel efficiency and also enhances the throttle response of your motorcycle.

You need to change your regular air filter almost every year, because they get clogged easily. When your air filter is clogged, your engine starts suffocating and it results to decrease your vehicle’s performance. However, the Free Flow Air Filters don’t get clogged easily and you don’t need to change them every year. In fact, you can use it for multiple years and all you have to do is just clean it about every two years. Even after using it for years, a good quality High Flow Air Filter provides better airflow as well as superior filtration of the air going to the engine of your bike.

Disadvantages  of a High Flow Air Filter:

Not guaranteed to happen, but the High Flow Air Filter may cause a little bad impact on the engine as well. If a low-quality High Flow Filter is used, your bike’s engine gets more exposed to debris and contaminants. It can also increase the amount of dirt/dust in your engine oil that can increase the wear of the engine’s moving parts.

Another problem with the High Flow Air Filters is that water splashed from the road can be soaked by this kind of filters. And this water can be induced to your engine, especially with the cold air intake. However, there are ways to avoid this problem as you can use a hydroshield or making sure to not drive through roads with high water.

Generally this kind of problems occurs only with the low-quality filters as they are not made with the precision that comes with a genuine filter of a good brand. So if you want to install a High Flow Air Filter in your motorcycle, only buy a genuine one from a reputed brand like K&N, S&S, TBR and Screamin’ Eagle.
