Perfect balance for high velocity air
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.

Pricey but best quality and less frequent changes
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.

Never worry...
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.

Works as Claimed
It is a Merv 8. I tried to buy a Merv 10 but was not available. I would have preferred more filtration.

Air Filters
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.

Shipping was great and filters are working fine.
