Minimum Efficiency Reporting Value (MERV) is a filter industry standard system that rates the overall effectiveness of air filters. Higher value MERV rating equates to finer filtration, meaning fewer dust particles and other airborne contaminants can pass through the filter. Other common ratings found within certain brands and stores includes FPR, MPR. They all follow the same basic principal, the higher the number the greater overall effectiveness of the air filter.

Choosing the correctly sized air filter is important in order to keep air clean in your home. An improperly sized filter may have limited performance. Determining the proper air filter size can be confusing, since filter packages generally display two sets of dimensions. It is important to understand that these dimension sets are the nominal and actual dimensions of the filter, and differences between the two.

When you place an order with RememberTheFilter.com you are charged at the time of purchase. The main reason for this is most of our filters are custom made after an order is placed and some filters have longer lead times. As an online retailer the credit card authorization that takes place when you checkout is only valid for 7 days. After 7 days we would no longer be able to collect payment - thus not send your filters. If you shop with retailers that do charge after longer periods they most likely save credit card information - we don't save credit card information. 

If at anytime you would like a refund or to make an inquiry regarding your order status please let us know. Our customer service representatives will be happy to help.
