Not always. Many people don't consider how a filter with a high MERV rating will affect other parts of the HVAC system. ... The reduction in airflow can have far-reaching implications in terms of performance and efficiency on your entire HVAC system.Oct 19, 2020
Do MERV 13 filters reduce air flow?
For example, let's say you have a pleated filter that's 1-inch thick and has a 13 MERV rating. Because the filter is thin and the MERV is high, it reduces airflow into the duct system. ... To make matters worse, this type of filter will reduce airflow even further once it gets dirty, which it will do very quickly.
Do some air filters restrict airflow?
All filters will restrict the air flow to some extent because, in every case, the air has to move through the filter for the unit to be able to remove the particles in the atmosphere. The higher the MERV rating, the denser the filter is going to be, and so the more restricted air flow will become.Nov 5, 2018
How does MERV rating affect airflow?
A higher MERV rating means a higher resistance, which means less airflow. When researching HVAC systems, airflow will come up a lot. That's because it's very important for the performance and longevity of your furnace or your air handler. Airflow is also the key to a comfortable home.Sep 20, 2019
Do I really need a MERV 13 filter?

Will an air purifier help protect me from COVID-19 in my home?
COVID-19Common questionWill an air purifier help protect me from COVID-19 in my home?When used properly, air purifiers can help reduce airborne contaminants including viruses in a home or confined space. However, by itself, a portable air cleaner is not enough to protect people from COVID-19.Jan 12, 2021
Can COVID-19 spread through HVAC systems?
COVID-19Common questionCan COVID-19 spread through HVAC systems?While airflows within a particular space may help spread disease among people in that space, there is no definitive evidence to date that viable virus has been transmitted through an HVAC system to result in disease transmission to people in other spaces served by the same system.
Can HVAC systems reduce the spread of COVID-19 in indoor spaces?
COVID-19Common questionCan HVAC systems reduce the spread of COVID-19 in indoor spaces?Heating, ventilation and air-conditioning (HVAC) systems are used to maintain indoor air temperature and humidity at healthy and comfortable levels. A well-maintained and operated system can reduce the spread of COVID-19 in indoor spaces by increasing the rate of air change, reducing air recirculation and increasing the amount of outdoor air coming in. Settings that recirculate the air should not be used. HVAC systems should always be regularly inspected, maintained, and cleaned.Mar 2, 2021
Are MERV 13 filters worth it?
Filters within a MERV rating of 17-20 are almost never necessary in a residential home. A MERV rating of 13-16 is considered hospital level air quality, so it is unlikely your home needs any more than that.Sep 20, 2019
