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.

Shipping was great and filters are working fine.
When it comes to filters, there is a fine line between too much that taxes the unit, and not enough to filter the air. I find these filters the perfect balance. Honeywell products are always designed well and this is no exception.
great service and a great product-grand slam!
Excellent product and fast shipping.
These thick filters are pricey but you don't have to change them as often as the thin ones. They are frequently not available in stores but ordering directly from Honeywell is the same price. They arrived in good condition and the last ones I bought from my local discount retailer was smashed so ordering online is the way to go. There are cheaper brands but Honeywell is by far the best quality.
I have set these up as a recurring purchase so that I don't even have to think about getting new ones and never worry about the quality.
It is a Merv 8. I tried to buy a Merv 10 but was not available. I would have preferred more filtration.
Exactly what I need for my new furnace
Seems to work fine. The whole process of purchasing this was easy and smooth.
This has been by far the best way to purchase air filters. We have 2 units at home so purchasing in bulk makes the most sense.
