How hard is it to find custom size filters?
How hard is it to find custom size HVAC filters??? Let me tell you, when you have an odd size, it is near impossible without spending hundreds of dollars!!! I had a really unusual custom size filter request. After reaching out to Mark to make sure they could do it, he assured me they could and so I went forward with my order. Once I got them, I could see how easily it would be to replace the inner filter with the outer frame. I placed them in my vents and they fit perfectly! I noticed a reduction in the dust that was coming through my HVAC almost immediately, no more flying fairy dust in the sunlight!! I am so happy I found a new home to get my weird sized custom filter frames and could not be happier with the excellent customer service! These folks are the real deal and I am happy to support a small American business! Thank you!!
