Which Is Better for Your HVAC System: HEPA or MERV Filters?

Your heating, ventilation, and air conditioning system has a filter that cleans the air in your home. This helps lessen the symptoms of allergies and asthma and contributes to the overall cleanliness of your house. The filter can clean the air moving around your house, which is then distributed back into the rooms in a pure form. So, choosing the appropriate filter per your requirements is vital for indoor air quality.

If you are familiar with the differences between MERV and HEPA filters, you will have a better idea of which kind of filter will work best in your house in Atlanta & surrounding metro area. However, this article will explain the MERV and HEPA filters and how to choose the best one for you.

What Exactly Are MERV Filters?

A grading system for air filters is the minimum efficiency reporting value, or MERV for short. To put it another way, the filter’s capacity to remove airborne contaminants improves directly to the MERV rating. An HVAC air filter’s minimum efficiency reporting value, or MERV, may range from 1 to 16.

It’s quite probable that the air filters in your HVAC system haven’t garnered much of your attention in the past. However, changing them as necessary is the best way to ensure your heating and central air conditioning systems continue functioning without a hitch.

The majority of your filters probably range from MERV 4 to MERV 8.

This only indicates there is a significant amount of potential for advancement! When you raise the MERV rating of your air filter, you must ensure your HVAC system continues to get an acceptable amount of airflow. If you are interested in upgrading to a filter of superb quality, it is strongly recommended that you seek the advice of a qualified heating and conditioning specialist. The number of contaminants in the air may be reduced by using one of many different replacement choices for air filters that are now available.

If the filter is of sufficient quality, it may even remove biological growth, smoke, and pollution from cars. They can remove airborne pollutants efficiently while using very little energy. Patients with allergies or asthma are strongly encouraged to use a high MERV rating filter.

What Are HEPA Filters?

There are strict air filtering requirements that HEPA filters need to fulfill. They are required to remove 99.97 percent of all tiny particles in the United States with a diameter of fewer than 0.3 microns. Even though HEPA filters are not graded on the MERV scale, their filtration capacities are far higher than those of MERV 16. So, filtration systems with HEPA filters might be helpful for those who suffer from severe allergies, like you.

The strength of these filters is that it would be impossible to put them in a household system without causing significant disruption to the flow of air. They have the potential to disrupt the normal functioning of the heating and cooling system. If your house has the best possible air filtration, you should consider having a skilled HVAC technician assist you in installing a HEPA bypass system.

Which Is Better for Your HVAC System: HEPA or MERV Filters?

First, all air passing through your HVAC system during operation cannot be run through a HEPA as it restricts too much airflow. The first step would be to update your primary filter to a 5” media cabinet that can hold a MERV 16 air cleaner media.

After operating the system for several months to get a feel of what clean air in the home is like, you could choose to go to the next step, installing a HEPA bypass system. This will take a small portion of the clean air out of the ductwork and clean it further to HEPA standards.

The HEPA system will have its own built-in fan that constantly pulls air out and cleans it, over time, all the air in your home will be cleaned, giving you all the health benefits. 

Consult a Professional

An essential step is to have a specialist specializing in HVAC and indoor air quality examine the equipment to determine what can be installed in your system. A professional can assist you in determining the extent of the issue with the air quality and the air filter size required to make the air in your house healthier and cleaner.

However, you may feel compelled to go to the closest hardware shop and buy your first air filter. Regrettably, this is not the most successful method, given that certain air filters are more effective and efficient than others.

When researching the ideal filter for your home’s ventilation system, you will probably come across suggestions for MERV and HEPA filters. What precisely differentiates the two from one another? And which filter do you think would work best in your house?

To get answers to these concerns, you must first consult a professional heating and cooling service near you.

A filter capable of capturing even the smallest particles is something that a homeowner should want. It is important to remember that the air will have a more difficult time passing through the filter if it is more effective. Because of this, your device may consume more power as it tries to force air through the filter. It is also possible that it may reduce the lifespan of your heating, ventilation, and air conditioning system.
