Works as air purifier

We attached it to a boxfan (rather than put it in a furnace) to create an air purifying system. It has cut down on the amount of sneezing considerably.

I wish it had an adjustable width fit, with accordion sides to keep the unfiltered air from leaking out.

I need three sizes of air filter: 12x24x2, 18x30x2, and 12x12x1, all MERV13. Filterbuy is the only place I found that has all three. A pack of six lasts me two years and this is a repeat order.

Perfect fit (the vent filter space on my HVAC is a little tricky), good quality and the convenience of getting 12 filters delivered for a great price cannot be beat!

Good value. Well constructed. Shipped quickly. They even used a box can be folded smaller or into custom dimensions.
