Whether your house has an HVAC central air system or simply a window-mounted or compact unit, you understand that replacing your filter on a regular basis is critical for the unit’s prolonged effectiveness. But do you have any idea regarding a system that relies on ducts and vents? For that, there are alternative ways of keeping dust and dirt out of your home.
For the last several years, vent filters have grown highly popular as a way to “double-down” on filtering to make sure that your house is dust, debris, and allergen-free. Usually, most of the vent filters are created to be a bit less efficient than HVAC filters in terms of overall effectiveness but powerful enough to stop bigger dirt particles, restrict insects from crawling inside, and make it simple to retrieve tiny things dropped inside the vent.
To learn further about vent filters and their function, read this article. It will provide you with more insight into this technology.
Understanding Air Filters
Vent filters are intended to be installed inside an air vent’s grating. Air vents are typically made of flexible fiber, foam, or fabric that can be extended to fill a cut or opening to fit perfectly within a duct.
Vent filters are different from HVAC filters when it comes to the number of filters you need to use. You’ll need a lot of vent filters to filter your home properly. HVAC filters are located directly outside a home’s central air system, requiring all circulating air to flow through the filter prior to going inside the system. Vent filters, on the other hand, provide the last level of filtration by passing the air that has already been treated through the filtering material. Unless you want to place vent filters in places where the quality of air seems to be more critical, like in a bedroom or living room, you’ll require as many vent filters as there are vents. For additional air purification, you can even use an air purifier.
However, if both HVAC filters and vent air filters are put to use in combination, they will turn out to be highly efficient and effective. It is because the air will first pass through the HVAC filter before entering the ducts, and in the end, it will pass through the vent filter before entering your room. So, the air filtering process becomes twice more effective in such a case.
Vent filters, like HVAC filters, will need replacement from time to time as the dust they remove from the air causes them to become clogged with time.
Vent filters may also be detached from the system for collecting objects that you may have dropped or fallen into the system, making vent filters a savior for little valuables like rings.
Air Filter: Working Explained
Let’s take a closer look at the working of the vent filter; however, we’ve just touched on it briefly.
Vent filters provide an extra layer of protection by preventing contaminants from spreading in the air you inhale through your home’s central air system.
While the HVAC system will filter away many of these contaminants, the vent filters will help make it even cleaner. Vent filters are normally stretched or cut to suit the size of each vent of the HVAC system. They are usually installed externally on the vent.
They serve as the final point of contact for air entering your house, as well as the last chance to clean or filter it before it reaches your breathing space.
Despite being installed externally, you can hide the filter by putting the duct’s grate over the vent again once the filter is installed.
It may be difficult to comprehend how a basic cloth-like foam or fiber can successfully cleanse the air, but the procedure is actually rather straightforward. The air is pumped out of the central air system and into your house.
The air will be properly filtered as it passes through the system before coming into contact with the vent filters at the very end. The air will go through the cloth or fiber that is obstructing the vent as it is forced out through the system.
Contaminants such as dust, on the other hand, will not be able to travel through the fabric. Because the contaminants have gotten caught in the filter, only pure air will be allowed to enter your home.
This happens at every filter-equipped vent, ensuring that the air entering your house is fully clean and healthy.
Are Vent Filters Effective Enough?
We now understand how vent filters actually work and function, but the main question is whether or not they are effective.
The short answer is that vent filters do function to a degree. They may eliminate contaminants from your air system, resulting in cleaner air entering your house than if you didn’t employ vent filters.
In contrast to other sorts of filters, the vent filters aren’t nearly as effective. A MERV rating is used to assess filters. The filter’s capacity to collect bigger particles is measured by this acronym, which stands for Minimum Efficiency Reporting Values.
Vent filters are seldom included in the MERV grading scale, demonstrating their inefficiency. They can, however, deliver cleaner air when used in conjunction with your HVAC filter.
So, while vent filters do function, they may not be the greatest solution if you want extremely pure air.
Overall, we can conclude that vent filters operate and accomplish their duty of eliminating contaminants from the air that reaches inside your home via the central air system.
They are, however, not the most efficient means of air filtration.
While vent filters provide a number of advantages, such as stopping tiny things from falling from entering the air system and preventing pests from crawling inside your home via the vents, they aren’t the ideal air filtering solution.
So, prior to installing vent filters, examine the HVAC filter properly if you believe that contaminated air is entering your home. You may also have custom air filters made to your specifications.
