Filters perform well, and I'm glad to be able to buy the odd size filter I need at Discount Filter.

Go the same quality as much higher priced air filters that had the same rating. Only had them in a couple of weeks, seem to do the job well. Delivery was good, had them about 5 days after order was placed.
