- Air Filters, indoor air quality, MERV
Some of the most common questions we get from homeowners is about air filters and MERV ratings. In the summer, when allergy symptoms can be at their worst, people want to ensure that they’re using the right filter for their needs and their air conditioning system. We’ve put together a quick guide to help homeowners make sense of the available options.
What is MERV?
MERV stands for Minimum Efficiency Reporting Value, and this rating indicates how effectively an air filter can remove allergens, dirt, dust and other contaminants from the air flowing through the HVAC (Heating, Ventilation and Air Conditioning) system. To put it simply, a higher MERV rating means your home has more protection against harmful airborne particles.
Is a Higher MERV Rating Better?
While it might seem correct to assume the filter with the highest MERV rating is the best choice for your home, there are some important factors to consider, mainly, not all HVAC systems are equipped to handle air filters with a high MERV rating. Incompatible filters can potentially hinder airflow and cause the system to operate inefficiently and lead to costly repairs.
What Filter Should I Use?
It’s hard to definitively say which filter you should use. Generally, a filter with a MERV rating between 8 and 13 will be perfectly suitable for your needs and HVAC system. However, if you’re unsure, you should consult with a certified HVAC professional to find out what filter is best for your home and system.
