Mechanical filters work by physically trapping particles as air passes through the filter. The two main types of mechanical filters are pleated paper filters and fiberglass panel filters.
Activated carbon filters use adsorption to remove particles and contaminants from the air. Adsorption is a process where molecules adhere to a surface. In this case, the molecules are pollutants and the surface is activated carbon.
Ozone generators produce ozone, a gas that is made up of three oxygen atoms (O3). Ozone is effective at removing certain contaminants from the air, but can also be harmful to human health if used improperly.
MERV rating system
The Minimum Efficiency Reporting Value (MERV) rating system is used to rate the effectiveness of air filters. The ratings range from 1-16, with 16 being the highest level of protection.
Filters with a MERV rating of 7 or higher are considered “high efficiency” and are effective at removing small particles such as dust mites, pollen, and mold spores.
Filters with a MERV rating of 13 or higher are considered “ultra-high efficiency” and can effectively remove viruses and bacteria from the air.
Choosing the right air filter for your HVAC system
When choosing an air filter, it is important to consider the specific needs of your home or business. The size of the space, the type of heating and cooling system, and the level of indoor air pollution will all play a role in determining the best type of filter for your needs.
If you have a forced-air heating and cooling system, you will need to choose a filter that fits your specific system. The two most common sizes are 1 inch and 2 inches.
