Disappointed to see that this filter had very few pleats and thus little filter material - looked cheap!

Untapped filters

These were for a Waterfurnace geothermal unit. The originals came taped together as 1 piece 30 x 36. I had to retrofit your filters to ensure dirt wasnt getting through the gap between them.

I couldn't be happier with my new filters. I ordered a year's supply and they fit great and it feels good knowing that I'm getting clean air throughout my home.

At this time I cannot honestly give 5 stars. So, far the filter I installed is working great. But, it's only been about 2 weeks. I really like that I was able to get this odd ball size at a very reasonable price.
