Furnace filters should be rated according to the MERV. This refers to Minimum Efficiency Reporting Value.

The range is between 300MPR-2800MPR where the higher number provide more filtration power. This is unique as many companies use the MERV.

MERV ratings range from 1 to 16. Given that the higher the MERV rating, the more the particles the filter will trap- the metric can help you define the best furnace filter.

Nevertheless, the filters with the highest rating allow less air flow which can lead to overworking of the furnace. Each MERV rating has a specific capability of the particles to trap. For instance:

MERV rating of 1-4. This rating is mostly effective when filtering particles which are bigger than 10 micrometers. These include, dust mites, pollen, textile fibers and carpet fibers. However, it has minimal filtration.

MERV rating of 9-12. This filters particles with a size of 1-3 micrometers. It is effective when it comes to humidifier dust, auto emissions, welding fumes. It is suitable in the superior residential.

MERV rating of 13-16. This filters are very effective when handling particles in the range of 0.3-1 micrometers. It traps all bacteria, most tobacco smoke, insecticide dust and cooking oil. It is suitable for surgery rooms in the hospital.
