The Best Home Air Conditioning Filter
Why is it important to consider
the Filter in your air conditioner?
What is the MERV-13 Filter?
MERV stands for ‘Minimum Efficiency Reporting Value’. This is a scale that shows the effectiveness of filters at removing particles of different sizes. The higher the number, the more particles the filter catches! As a reference, the ratings go from 1 (low) to 16 (exceptionally high filtration).
The MERV-13 Filter catches up to 90% of particles in the range of 1-3 µm range i.e. where PM2.5 exists. This is perfect for homes where people suffer from asthma, allergies or any other respiratory illnesses.
What does this mean?

Did you know?
Particulate Matter 2.5 (PM2.5) are droplets and tiny particles in the air that are 2.5 microns or less in width. These particles are small enough to travel into our lungs. Long term exposure to these particles can cause respiratory issues. People with cardiovascular and respiratory health concerns can be especially sensitive to PM2.5.
During the 2019-2020 Australian Bushfires; this is why authorities were recommending people to stay home or wear an N95 face mask when outdoors.

Frequently Asked Questions
MERV-14 to 16 are used in facilities where it is critical to have extremely clean air such as operating theatres in hospitals. These filters can almost eliminate all airborne contaminants. Generally, these are not recommended for residential homes as it will greatly restrict the adequate airflow needed in a home. It is very important to meet halfway and make sure that you have enough airflow and removing as many contaminants as possible. Make sure you consult your HVAC specialists before you get a filter installed.
Within a typical home, the MERV-13 strikes the right balance between efficient filtering and adequate airflow. Filters in lower MERV ratings cannot catch contaminants on a smaller scale that can affect asthma, allergies or any other respiratory concerns. For example, a MERV-8 doesn’t filter out smog, smoke, virus carriers, cooking oil, and cough and sneeze particles.
Majority of viruses spread via droplet nuclei i.e. sneeze and cough particles which range from 1 to 5 microns. These droplets then evaporate and stay suspended in the air for a long time. The MERV-13 filter can remove up to 90% of contaminants within 1 to 10 microns and even up to 50% of 0.3 to 1 microns.
