Title says it all (or almost all!) get a full case of 12 (TWELVE!) filters for the price others are selling only 6 for! The TITLE indicates the size being sold. Photo is for illustrative purposes as 3M continually changes their package designs. While Filtrete uses their own rating term MPR (Microparticle Performance Rating) to rate their filters, my research on the web indicates this is equivalent to a MERV 11 (Minimum Efficiency Reporting Value) stored in box ** Multiple purchases get reduced combined shipping. I changed the shipping charge on all my listings to the fairest rate possible, using the US Postal Services (USPS) rate chart, based on your ZIP Code or Country, as provided by products built-in postal rate system.Multiple item wins will receive a combined discounted shipping charge, assuming all items fit into a single box. Thank you for your buy, and good luck. International First Class Postage is less expensive than Priority Service, but First Class has a maximum weight of 4 pounds and some size restrictions too. If I am forced to use Priority Service, I will inform you of any increase in shipping costs for you to pay. Thank youTake care and happy looking! Powered by product .
