HEPA filters: Understanding how filtration helps an AC system

When it comes to the air conditioning system of the home, most home owners do not consider the integral parts of the unit. The only concern we have is that our AC unit works. However, it is important to understand that an AC unit is not only cooling the air of the home but also providing clean and sanitized air to breathe. The filtration system of the air conditioning unit is what provides us with the clean air. This is why it is so important for every home owner to change their filters on a regular basis.

One filter option that is very popular is the HEPA filter. The term HEPA stands for High Efficiency Particulate Air. This means the filter will purify the air better than a regular filter as it is created to do so. This filter is very special and has the ability to capture at least 99.97% of the particles in the air that are of .3 microns of diameter. This is very, very small and why the HEPA is the perfect choice for home owners who have respiratory issues. This filter will take out most every element in the air that can be harmful to breathe.


Because a HEPA air filter is so efficient, they not only allow you to breathe easier, but they also help keep your unit running smoothly. This filter will remove the items in the air which would normally come through and out of your AC unit. Such items include: pet dander, dust mite particles, pollen, allergens and mold spores.

These filters are usually used in hospitals, surgical rooms and other areas where the particles must be removed to keep the room sanitized. However, these filters also work well in the home, especially for those who suffer from respiratory diseases or those who have allergy issues.


One of the best options that can be used is a Hepa-Pure filter. This option can be purchased online and uses several layers of pleating to provide a larger area to collect the dust and other harmful items that can be in the air. These filters can also be cleaned quite a few times, so you not only have clean air in the home but an investment which can be used over and over.

HEPA filters definitely have their advantages. When purchasing a new air filter for your harm, give a HEPA option a try. You may find that you breathe easier at night and have an easier time enjoying the comfort of your own home!
