Should You Use Cheap or Expensive HVAC Filters?

Air filters play an important role in the quality of your home's indoor enrolment and the air circulating throughout your living spaces. Some homeowners concerned about indoor air quality are under the assumption that more expensive air filters are a worthwhile investment. As for whether this is true, we discuss this issue a bit further below.

Why an Air Filter Is Necessary

Air filters are designed to remove an assortment of impurities from the air that circulates in your home. This is done with layers of various materials that get into your indoor air. A properly functioning air filter benefits you by:

  • Creating a safer indoor space for children, the elderly, and pets
  • Removing an assortment of airborne impurities, including mold spores, allergens, and airborne pathogens
  • Helping your HVAC system work better - and reducing the need for costly repairs
  • Managing indoor pollution levels

Why You'll Find So Many Air Filter Choices

Filter manufacturers know many homeowners - and business owners, too - are concerned about the quality of indoor environments today. For this reason, they tend to make an assortment of choices available to consumers. Some of these filters are lower-quality and designed with affordability in mind, but others are a bit more of an investment.

MERV Ratings and Air Filter Quality

Air filter quality is measured by the Minimum Efficiency Reporting Value (MERV). The higher the rating, the higher the quality of the filter and its ability to filter out potentially harmful and unwanted impurities and contaminants.

More Expensive Air Filters Can Equal Higher HVAC Costs

Just because higher MERV-rated filters are available doesn't mean you'll benefit from them. Hospitals, for example, often use air filters with a 15-16 MERV rating. While this level of filtration makes sense for hospitals and similar medical facilities, it's not all that beneficial for homeowners. 

In fact, a filter with an excessively high MERV rating is designed with more layers, which means your HVAC system has to work harder to push air through it. This, in turn, contributes to increased HVAC-related costs.

Finding the Right Air Filter for Your Needs

The type of filter appropriate for your home depends mainly on your indoor air quality concerns. If, for example, you have pets or regularly prepare foods with stronger scents, you may prefer a high-efficiency particulate air (HEPA) filter. 

These are higher-quality and remove about 99 percent of all airborne pollutants and contaminants. HEPA filters are more expensive but still worth considering if you prefer or need a higher level of filtration. This can also be the case if you have allergies or household members with respiratory concerns.
