    Understanding the Mechanics - How Do Home Air Filters Work

    These days everyone focuses on a healthy way of living. But no one can deny the importance of an indoor air filter in healthy living. Because these filters help in cleaning the indoor air, and save us from many harmful diseases. So the question that arises here is How Do Home Air Filters Work? One common size you might come across when searching for air filters is the 20x25x1 air filter a dimension widely used in HVAC systems.

    Here we will explore various aspects of air filters and how these are helpful for day-to-day living.

    The Basics of Home Air Filters


    There are various airborne particles present in the air. These particles come from outside. And are harmful to the lungs and can cause various diseases. So the air filters capture all the pollutants. And clean the air space. Here is the list of those pollutants cleaned by the air filters. dust, pollen, pet dander, mold spores, and other pollutants.

    Composition and Structure


    The primary work of air filters is to capture these particles. And they do this with the help of their structure. They have a fibrous and porous structure. So they allow air to pass through and during this process, they capture all the particles. The air filters are primarily made of fiberglass, pleated paper, polyester, and high-efficiency particulate air (HEPA) filters. 

    The  20x25x1 is the basic size of an HVAC system. This size of filter is not big or small. Hence can easily work together with other devices like healing and cooling systems. So 20x25x1 is the first choice for everyone.

    Filtration Process


    The filtration process is very basic. The air filter takes in the air from the surrounding environment. Then the fibrous and porous membrane of the filter captures all the suspended materials from the air. The effectiveness of the filter depends on its MERV (Minimum Efficiency Reporting Value) rating. The higher will be the rating the more effective will be the air filter.

    20x25x1 filters are available in various MERV ratings. These ratings decide the size and the price of these air filters. If you are choosing the higher rating filter then they can capture even the smallest particles. While the low-rating ones are restricted to capturing certain types of particles. The choice of the air flyers depends on your use.

    Types of Home Air Filters


    There are different types of air filters available, each with its advantages and disadvantages. The choice of air filters depends on many factors. Like the requirement of the filtration, budget, and other specific needs.

    Here are some common types of air filters that you can choose from:

    • Fiberglass Filters – These are mainly for capturing large particles. And these are cost-effective and disposable ones.
    • Pleated Filters – These filters have the largest surface area. And these are very customizable. Hence available in various ratings. You can choose these according to your needs and budget. These are effective in cleaning the small particles too.
    • HEPA Filters These are for those areas where the air filtration is a must. Like a hospital and a laboratory. These are very effective and can clan the particles of size 0.3 microns. So these filters are the best of all.

    Maintaining Home Air Filters


    You must clean your air filters regularly. Because captured air particles can clog the filter. This will lead to decreased efficiency of the air filter. It is recommended to check and replace filters regularly, with the frequency depending on factors such as filter type, MERV rating, and environmental conditions.

    The 20x25x1 size filters can easily replaced. So all you have to do is purchase the filters in advance and whenever you feel the old filter is not working. You can easily replace the filter with the new one. This approach will not only help you to get the constant filtered air but also help in increasing the life span of the HVAC system.

    Conclusion


    Now you know how do home air filters work. The working process of these air filters is not complex. But you have to decide your requirements. If you want a high-quality air filter then you have to invest more. And if you are only looking to capture large dust particles then your budget will be minimal in this case.

    Air filters help in maintaining indoor air quality and protect us from various harmful lung and other diseases. These air filters are required in today’s living.
