Air Filters: What to Know

Air Filters

When you are breathing in the fresh air entering your home, you want it to be clean, right? Of course you do, otherwise, the air may contain all kinds of pathogens, contagions, dust, dirt, sand, mold, bacteria, viruses, allergens or pollutants. In order to prevent this, we have air filters. These useful tools are capable of filtering out the worst elements out of airflow and keep the fresh air coming in without issue. The tools work constantly and do not require anything more than simply putting them in the system. When working, they trap and absorb harmful particles while letting airflow into your home.

Air filters are used to clean up airflow so that the indoor air quality of a home is raised in the process. This is mostly the result of the filters MERV rating, which helps you see how effective it is at cleaning out incoming airflow. The weaving is what is being judged and the tighter it is, the more particles it is capable of stopping. However, the tightness of a filter also presents a problem. You need to make sure the filters you buy are average in rating or you face issues for your home as a whole.

Ratings and Why They Matter

Air filters for your home are made with the idea that they will allow airflow through without any issues. However, when the filter’s MERV rating is too high then that means that it becomes much more difficult to have air come in through. This is due to the mesh weaving being so tight that even has a tough time coming through into the systems behind the filter. While this does mean cleaner air, it also causes problems and is a large part as to why air filters of higher MERV ratings are reserved for office buildings with more powerful air systems.

You need to be more careful with what types of air filters you choose to place into your home systems. To this end, look through the owners manual for your air system and check up on the air filters sizes needed and if there is any specification on MERV ratings required. The average home air filter MERV rating needed is around 8 or 9. Any number less and harmful particles could sneak their way in, any more and the airflow will have trouble coming in.

Other Problems with Airflow

The air filters in a system need to be clean or the loss of clean airflow will affect more than just the air quality of your home. When the air filter is dirty, it becomes so full of captured particles that air is unable to pass through into your home. The system will keep trying to push the air inside but when it cannot this could lead to the system becoming damaged. You may need to pay a raised energy bill as well as for repairs on the system.
