Everything about Central Air Filter

Air is a matter we cannot avoid in our everyday life. It is one that keeps us surviving. But it can also bring to us some damaging effects. As it is widely circulated, it is the melting pot of countless microscopic organisms and particles which pose a danger to humankind. It has dust allergens, pet or hair dander, mould and numerous germs in it. So it is not a wonder how we get colds, runny noses or difficulty breathing from time to time. Nowadays, air filtration systems are needed to keep us surviving.

Benefits and disadvantages of central air filter

A filter screens out unwanted particles such as dust, dust mites, mould spores, pet dander, pollen, smoke, bacteria and viruses, and more in the room air where it operates. It provides air filtration for the whole house because of its central air filtration system. Thus, it allows the whole family to breathe healthier air. Filtered air is beneficial for people with asthma and allergies. The system works very efficiently and very quietly. It is located in discreet areas which do not pose risks. Central filters are integrated into the heating system.

On the other hand, the filter operates only when the HVAC is working; thus, it does not ensure continuous air filtration. Another problem with it is its cost – a relatively expensive range of $1500 to $2500.

Kinds of central air filter

Electrostatic air filter has been dubbed as the most efficient air filtration technology suited for residential homes. The filter makes use of electronically charged filters which can easily attract and cling to allergens, dust and other irritants. It is reusable and can be cleaned as needed. Though very large in size, which is difficult to fit in furnace filter slot and expensive to buy, an electrostatic air filter still is regarded to operate more effectively than standard or pleated ones.

A regular furnace filter is a simple air filtration unit that operates with minimal efficiency. It is designed to filter large particles, such that the standard glass furnace filter is estimated to remove only about 10 percent of the airborne particles. It is one of the most inexpensive air filters, with an average cost of about $1.00, and it is a throwaway type.

Pleated air filters are made of a heavy paper fan that is folded to form pleats on the surface. This kind of filter is craftily designed to fit into the furnace filter slot. Unlike the regular air filter, it draws 30 to 40 percent of air particulate, which provides better air filtration. Because of this, it is slightly more expensive than the glass filters, costing about $10.00. Its lifespan is about two months and it is then discarded.

Maintenance of central air filter

It is very important to clean and maintain air filters as their primary function is to keep the interior of the air conditioning system clean. So as it filters and cleanses air particulates, it should also be cleaned once in a while. It may have accumulated much debris, that if not replaced or maintained, the efficiency of the air conditioning system will surely be affected.
