This is probably the 3rd time I have ordered these filters directly from Honeywell. Before that, I was ordering them from Amazon - where the price is much higher. The product works as expected and is delivered in a timely manner. I'm very happy with the ordering process and plan on continuing to order from Honeywell

These filters do a great job filtering out dust and pollen. I'm also able to use the filter longer than other filters before I have to replace it
