Your Guide to Common HVAC Filters

hvac filters

The global market size for HVAC filters was worth an estimated $6.1 billion in 2020. Growing demand for these essential HVAC components will push that figure to an astounding $11 billion by 2028.

HVAC filters help filter foreign particles such as dust, pollen, and chemical pollutants from your indoor air. Some trap over 99.9 percent of particles, ensuring that you never have to worry about indoor air pollution.

Preserving the integrity of your indoor air quality (IAQ) can help avert health issues, including allergies. By stopping pollutants from entering your HVAC, filters avert potential damage to your HVAC equipment.

In today’s post, we discuss the six top HVAC filters in the market today. This way, it’s easier for you to see which filters to purchase as part of your HVAC preparation for the summer ahead. 

HEPA Filters

HEPA stands for high-efficiency particulate air. As the name suggests, HEPA filters are incredibly efficient when it comes to purifying the air. 

These filters can remove at least 99.97 percent of all inborn allergens and pollutants. Even particulates as tiny as 0.3 microns stand no chance, including tobacco and bacteria. It’s no wonder the U.S. Department of Health recommends these filters.

Given that HEPA filters need replacement every few years, they’re cost-effective. 

But despite the unquestionable effectiveness of these filters, they’re still against certain pollutants. These pollutants include fumes and gasses as they’re too small for the filters. Some pollutants such as mold spores often settle on the filters themselves, shortening their useful lifespan. 

You can purchase HEPA filters from most HVAC companies out there. 

UV HVAC Filters

UV filters work by using shortwave UV light to eliminate bacteria and viruses. As air passes through your HVAC system, the UV lamps use germicidal radiation to disinfect it. 

UV HVAC filters are especially useful for killing mold spores and other microorganisms that are potentially harmful to your health. These filters also work continuously, even when your HVAC system is offline. Thus, you’re guaranteed toxin-free air round-the-clock. 

The main drawback of a UV filter is that it can convert oxygen into ozone. This gas is potentially dangerous, even in low amounts. It can cause a variety of health problems and worsen existing ones, including coughing, chest pain, and asthma. 

UV filters are also fairly costly to install and require replacement each year. The filters are also ineffective against such common pollutants as dust, allergens, gases, cigarette smoke, and fumes. 

Washable Filters

Unlike most types of air filters that are disposed of and replaced after a while, washable air filters come with the option of washing and reusing the filter over and over again. These filters are thus an eco-friendly option and can help you save money in the long term. 

The initial price is a bit higher compared to most other air filters, but view this cost as an investment that will last a long time. These filters can easily last ten or more years, unlike some other filters that need replacement every few months.

Always make sure that the filter is completely dry after you’ve washed and vacuumed it. Even a slight amount of moisture can cause mold or mildew growth, which would contaminate your air. 

Electrostatic Filters

Electrostatic filters use tiny cotton and paper fibers to create static that then acts as a magnet for airborne particles. The magnetism generated keeps the particles from spreading throughout your indoor space, which makes electrostatic filters effective in combating allergens. 

Consumers can choose between reusable and disposable. Therefore, when the time comes for changing your HVAC’s filters, you can decide whether to toss the current one away or wash and reuse it.

Media Filters

Media filters are popular for providing more benefits than most other filters, including standard filters with impressive MERV ratings. That’s because, while media filters can match the level of filtration of other highly efficient filters, they do not cause static pressure or airflow issues. 

Media filters generally feature a larger surface area. This provides better filtration while significantly averting static pressure. All the filtered particles get sealed into the filter, preventing them from being expelled back into your indoor space.

You’ll also love the fact that media filters are remarkably easy to maintain. These filters are also cost-effective and sturdy. They need replacement once or twice every year.

Note that you’ll need an expert in heating and air in Columbia, SC, to install a media filter. 

Fiberglass Filters

Fiberglass filters are among the commonest types of air filters around. These disposable filters are quite affordable. They also do an excellent job protecting your HVAC from debris, thus averting frequent air conditioning repair

The main drawback with fiberglass filters is that they don’t do an excellent job when it comes to improving indoor air quality. These filters only trap some dust and allergens and are helpless against smaller pollutants. They also tend to get clogged over time and won’t function properly, especially if you don’t replace them at the right time. 

Fiberglass filters are easily available in shops that specialize in HVAC in Columbia, SC. 

Choose the Right Filters for Your HVAC System
