Cheap vs Expensive Air Filters: Does Price Really Make a Difference?

What Are Air Filters?

Air filters are a crucial component of your HVAC system. They are designed to remove contaminants and particles from the air before it’s distributed inside your home. These particles can be pollen, dust, pet dander, and other allergens. They can also be viruses and bacteria.

Deciding Between Cheap vs Expensive Air Filters

Replacing your air filters can set you back $40 to $200 a year. That’s a pretty wide price range so it’s natural to wonder if paying for an expensive model is really worth it.

Cheap Air Filters

Cheap air filters are usually made of fiberglass and other synthetic materials. They’re designed to be replaced every 30 days or so. They are generally sold in packs by most home improvement stores. These filters are affordable and easy to replace, but they may not be as effective at filtering out small particles compared to more expensive options.

One of the main issues with cheap air filters is their MERV (Minimum Efficiency Reporting Value) rating. The MERV rating measures the effectiveness of the filter at removing particles from the air, with higher numbers indicating better performance.

Cheap air filters usually have a MERV rating of 1 to 4, which means they are only effective at capturing larger particles like dust and pollen. They may be unable to filter out smaller particles like bacteria and viruses, which can be a concern for those experiencing respiratory issues or compromised immune systems.

Expensive Air Filters

On the other hand, expensive air filters are usually made of higher-quality materials like pleated paper or HEPA (High-Efficiency Particulate Air) filters. These filters are designed to last longer than cheaper options and may only need to be replaced every 6 to 12 months. They also have higher MERV ratings, usually between 8 to 13, which means they do a better job of filtering smaller particles.

HEPA filters, in particular, are known for their ability to remove 99.97% of particles from the air that are as small as 0.3 microns. This makes them an excellent choice for people with allergies and respiratory issues, as well as anyone looking to improve the overall air quality in their home.

Does Price Matter?

The answer is yes and no. While more expensive air filters may be more effective at removing particles from the air, they aren’t automatically the best choice for everyone.

If you live in a relatively clean environment and do not have any respiratory issues or allergies, a cheaper air filter may be sufficient. However, if you take care of pets, live in a dusty area, or have respiratory issues, it’s a good idea to consider more expensive filters that have higher MERV ratings.



It’s also important to note that the cost of the filter isn’t the only factor that you should consider. Cheaper filters may need to be replaced more frequently which can be more expensive over time. Pricier filters last longer and need to be replaced less often which can be more cost-effective.

Cheap vs Expensive Air Filters: Additional Considerations

Here are a few additional aspects to consider when deciding between cheap and expensive air filters:

Environmental Impact

Cheaper air filters are often less durable and need to be replaced more frequently, which can lead to more waste. Expensive filters can be reused or recycled, which can help reduce your environmental impact.

Health Benefits

Investing in a high-quality air filter can have significant health benefits, especially if you have certain health conditions. 

Energy Efficiency

Cheaper filters may restrict airflow and cause your system to work harder, leading to higher energy bills. More expensive filters with higher MERV ratings can help improve airflow and reduce energy consumption.

Consider your individual needs and budget when deciding between cheap vs expensive air filters. And don’t hesitate to consult a professional HVAC service like C&G Heating & Air Conditioning if you need more advice on the type of filter you should get.
