AC Filter: Everything You Need to Know

As the summer season approaches, it’s essential to keep your air conditioning units in optimal condition, and an AC filter is an essential component that plays a key role in ensuring your home stays at a comfortable temperature. As such, we’ve prepared this comprehensive guide outlining everything you need to know about AC filters.

What is an AC Filter?

AC filters are screens placed in the air conditioning system that help purify the air circulating in your home. It prevents dust, dirt, and other debris from entering your home and maintains the indoor air quality. As your AC operates, it pulls air into the unit and filters it through a sheet of fibrous material designed to collect pollutants.

Types of AC Filters

There are various types of AC filters in the market, and each has its own advantages and disadvantages. Below are some of the AC filters to consider when purchasing a new filter.

1. Fiberglass AC filters

Fiberglass AC filters are the most common and least expensive type of filter. These filters are made of layered fiberglass that is held together by a metal mesh. They capture large particles, preventing them from entering your home, but they are less effective at trapping smaller particles.

2. Pleated AC filters

Pleated AC filters are more efficient than fiberglass filters. They consist of layers of polyester or cotton that have been folded like a fan, making them more effective in capturing small particles. Pleated filters are a bit more expensive than fiberglass filters, but they offer a better air cleaning performance.

3. HEPA AC filters

HEPA stands for High-Efficiency Particulate Air. HEPA AC filters capture 99.97% of particles as small as 0.3 microns, making them a top-performing filter. They are the best choice for people with allergies or respiratory issues, but they are also the most expensive.

AC Filter Maintenance

To keep your AC unit working efficiently, it is necessary to change your air filters regularly. Typically, most air filters require replacement every three months, depending on usage. Neglecting to change your AC filter has a negative effect on your health, and the well-being of your air conditioning system. When airflow is restricted due to a dirty filter, the unit has to work harder to cool your home, which may lead to malfunctions.
