3 Things You Should Know about Your AC’s Filter

How often do you change your air conditioner’s filter? Is it once a month? Once a year? Is it something you’ve been neglecting to do for a long time? We know that changing the air filter isn’t on the top of everyone’s priority list, but we have some things to share that may change your mind.

#1: It was designed to protect the system.

The first air filters were not actually designed to help make your home healthier. While it’s an added bonus, and while they are optimized for air filtration today, air filters also stop particles from damaging the AC equipment.

Air is sucked in from around your home before it cools down at the evaporator coil. If dust and debris came through as well, the air conditioning system could undergo some major damage, so engineers designed this small part to block them as air comes through.

#2: Neglecting to change the filter can be very damaging.

Oftentimes, when an air conditioning system is damaged, the problem can be traced back to the filter. Neglecting to change it once every month or so stops air from coming through, not just particles. When airflow is obstructed, the system cannot do its job properly, so you’ll be more likely to need repairs and have an overworked system that takes too long to cool you off.

#3: There are different ratings for better filtration.

The standard air filter has a MERV rating that is no more than 4. The minimum efficiency reporting value (MERV) of an air filter is what you probably expect—an indicator of its efficiency—but you can go much higher than the standard number. The higher the MERV, the cleaner the air!

However, if you choose a filter with a MERV rating that is too high, it may not be effective at protecting your AC system. A strong filter could block air from coming into the system, just as a dirty filter can. Consult a technician before you buy!
