Every HVAC system comes with a standard air filter, but the job of this air filter is not to improve your indoor air quality; rather, it is to help reduce the amount of dirt, dust and debris that can enter your system.

MERV Ratings: Why They Matter
Air filters come with a rating known as MERV, which stands for minimum efficiency reporting value. This number tells you how effective a particular filter is when installed into your system. MERV ratings range from 1 to 20, with residential use typically ranging from 5-12. As an example, the standard filter that comes with your HVAC system usually has a MERV rating between 1-4. Other ranges break out as follows:
- MERV 5-8 – captures pollen, dust mites and dust mite debris, sanding dust, textile fibers, carpet fibers, some mold and mildew spores and pet dander.
- MERV 9-12 – captures the above-listed items and these additional ones: Legionella, Humidifier dust, lead dust and auto emission particulates.
- MERV 13+ – filters with a MERV higher than 12 can start to restrict air flow, so it’s important to consult a professional about using a filter with this high of a MERV rating.
Reasons to Install an Air Filtration System
The main reason to install an air filtration system is to improve your indoor air quality. Here are a couple of more reasons to consider installing an air filter:
- Better energy efficiency – a stronger, better air filter removes more contaminants from the air, which can help improve the air flow in your system.
- Less stress on your system – improved removal of items that can clog your system, like dirt and dust, allows your system to work optimally, reducing levels of stress.
- Help for allergy sufferers – stronger air filters can remove far more allergens from your indoor air, which can go a long way toward reducing the effects of allergies.
