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.

Allergy help-clean air
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.

First time trying these
First time buying these. They look to be similar in construction to the competitors FRAM & 3M Filtrete at a better price. Good customer service, fast reliable shipping, and a good price! I'll use these on three units with my NEST thermostats which monitor usage and tell when to change. We'll see how long they last and perform compared to others I've used.
Great Value
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.
