MERV = 'Minimum Efficiency Reporting Value' this is used to rate the overall effectiveness of an Air Filter. Below you will find a table that measures the MERV strength and tells you the Application of each unit's effectiveness. In general an Air Filter with a higher MERV Rating is more effective and has a broader application, but most residential homes will find the best use from an air filter between the 5-13 MERV rating.

Seriously, these filters were tested in-depth on a YouTube channel called Project Farm. They were the best balance of protection from dirt, dust and contaminants, and also allowing air to flow so that your air conditioner and furnace doesn't struggle to an early death. I won't buy anything else.

These are great filters at a very good price. We have 3 filters that need changed every three months. That adds up in a hurry, so being able to get Honeywell filters at a lower price than at the local home improvement center is fantastic.

The AC repair man told me to throw away the cheap filters like the one that was crumpled up inside my AC and buy the Honeywell Filters. My allergies are better and even less dust in the house.
