There are many different types of air filters to choose from. The one that is the best for you, depends on what kind of heating and cooling system you have and if it requires a particular kind of filter. If you have the choice in filters, you’ll need to use the one best for your needs. Specifically, choosing best air filters for homeowners in Kingsport, Johnson City, and Bristol, TN.

How to decide what kind of air filter

Before you buy air filters, first answer these questions:

  • filter size
  • air quality and dust/dander removal
  • air flow

Ultimately, the choice for which air filter you need depends on your level of indoor air quality needs. Leinbach Services technicians will listen to your needs and help you decide which air filter will work best for your home and budget.

Filter Size

Find the size that is right for your unit to ensure adequate air flow and air quality. Each heating unit is built differently. Therefore, any single unit may not have the same size filter as the next. If the filter is not sized correctly to fit your unit, do not bend the filter. This will minimize the air flow cleaning potential. Contaminated air will travel around where the filter is bent replacing it back into your establishment and on your system components.

Air Flow

For most filters, it is pertinent that you replace your filter once a month. Yet, some filters such as a high performance filter can withstand a span of 90 days. In the turn of irregular replacement of your heat and air conditioning unit filter, the dust, dander and other particles caught in the cycling of air between your establishment and unit can restrict the air flow. With this restricted air flow due to a dirty filter, your unit works harder to function while it is being starved for air because of the unclean filter. The more worked your unit and its components are, the more chance there will be of faulting and eventually breaking of your heating and cooling system’s parts.

Air Quality

For people with allergies, excellent air quality is a must. The choice you make on increasing air quality within your establishment will affect how you live within your residence or how employees work within your business. Each kind of filter provides different features to increasing air quality. Yet, the best filter theoretically for removing more dust and dander are pleated filters. If pleated filters are not the right option for you, certain filters are available in tightly woven formats where more particles are caught within the process. Each filter encompasses a Minimum Efficiency Reporting Value (MERV) rating. The higher the MERV rating, the fewer particles that passes through the filter. Typical filters with a 1-4 rating are washable, electrostatic or fiberglass throwaways. A 5-8 rating normally encompasses pleated, cartridge and some throwaway filters. Filters with ratings higher than a nine provide superior air quality.

Difference in materials used for air filters

Fiberglass air filter

Although cheaper than others, fiberglass air filters aren’t recommended by any HVAC brand. These filters have a low air flow quality because they allow most dust to pass through, so, this filter actually decreases indoor air quality.

High Efficiency Particulate Arrestance (HEPA) air filter

If you are looking for efficiency, the High Efficiency Particulate Arrestance (HEPA) filter is your best choice. A HEPA air filter will remove almost all allergens from the air that passes through your heat and air conditioning equipment by trapping particles in the deepest point of its thick pleated surface area encompassing roughly 7 pleats per inch. Yet, if not maintained properly it can restrict airflow through your heat and air conditioning unit. Unlike most other filters, you can clean and reuse HEPA filters.

Electrostatic air filter

An electrostatic filter is permanent and washable requiring monthly cleaning. If not properly maintained these filters will restrict air flow.

Poly air filter

A poly filter maintains higher efficiency over the life of the filter. These filters have the ability to use an electrostatic charge allowing more to be captured in the filter within air transfer between your establishment and HVAC unit.

Pleated air filters

The most popular filter, this one catches dust in the lowest part of the pleat. Pleats range in thickness of 1 to 6 inches. Airflow becomes restricted if not changed regularly.
