Is the Furnace Air Filter the Same as the Air Conditioner Filter?

In general, your heating and cooling system share the same air handler and the same filter. However, if you have two separate heating and cooling units, each unit would have a separate filter.

Things to Consider before Purchasing an Air Filter

When you purchase an air filter, consider the following factors:

Efficiency

Air filters are usually given a Minimum Efficiency Reporting Value (MERV). This rating helps you determine how well the product catches particles. Home filters usually generally have a MERV rating of 1 to 13. This number signifies how efficient the filter is, a high MERV rating means the filter can collect more particles.

Keep in mind, however, that the higher the MERV rating, the lower the airflow. It could be more expensive to run the unit because the air filter will cause more resistance.

Size

To choose the right size air filter, calculate the square footage of the room. Measure the length and width in feet and multiply the 2 numbers together. Buy an air filter with a square foot coverage that corresponds to your room’s measurements.

Type

There are several different kinds of air filters, including the Flat-paneled fiberglass air filters, pleated media air filters, HEPA air filters, and washable air filters.

Consider your requirements. If you have allergies, you should choose an air filter especially constructed for allergy relief. These models feature HEPA filters, (High Efficiency Particulate Air filters), which are proven to destroy 98% of airborne allergens. HEPA air filters are considered to be the most effective air purifiers in existence.

Features

Are there any special features you require?  For example, elements such as handles, wheels, remote controls, multiple fan speeds, filter change indicators, and air quality sensors give you greater control over the performance of your product.

Performance Rating

You also need to consider the MERV rating (minimum efficiency reporting value). A MERV score is an indicator of the size particles that can go through the filter. People with asthma should purchase a filter with a MERV rating of at least 12.

Remember:  the right air filter can improve the air quality of a home and reduce allergies.

Indoor air is often much more polluted than the air outside. Indoor air pollution is considered to be a major health risk. Filters aggressively trap dust and allergens from the air and help create a cleaner, fresher, environment.

MERV ratings provide a standard comparison of air filter performance. A higher MERV rating signifies greater efficiency and increased protection against airborne particles.

The other 3 filters are impressive and have many good qualities:

  • The Filtrete Healthy Living Elite Allergen Reduction Filter is created with Filtrete Brand 3-in-1 technology from 3M
  • The Filter Buy AFB MERV 8 Pleated AC Furnace Air Filter This filter is configured with a pleated surface area to trap more dust particles.

In spite of their numerous assets, the other three filters are not HEPA.

Asthma and allergies can seriously impact a person’s health and the quality of an individual’s  life. The other 3 filters have some impressive qualities, but even if all else were equal, I would have more confidence in the HEPA models because they are considered to be the best by many experts and consumer groups.

The chosen models feature HEPA filters, (High Efficiency Particulate Air filters), which are proven to destroy 98% of airborne allergens. HEPA air filters are considered to be the most effective air filters that can be purchased today. I believe I just have more confidence in the HEPA Models.
