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 5-12 MERV rating.

I have not used my new filter yet. I bought it as a backup. I want to commend you for the excellent box my filter was sent in. Other companies are not using very good boxes, so filters arrive damaged. Thank you also for the quick shipping time.

I got exactly the kind of Honeywell Air Filters that I ordered. They are very efficient and the price is better than I can get from my HVAC company so I am happy.
