This filter was an odd size and I was having trouble finding it locally. It fit correctly. The quality was acceptable. I was expecting a faster ship time, but it wasn't advertised that way, so maybe I just had an unrealistic expectation. From order to my door was 9 or 10 days.
Filters look good although the packaging cardboard was a little beat up. I am using each filter for two months which has not been reached yet for the first filter. The air is smelling clean.
I was definitely a skeptic, but now I am a convert. After using Flanders only for years, I decided to give Filterbuy a try with the expectation this would be a short lived experiment like box store products. Receiving them I couldnt be more pleased with the quality, even on oddball sizes that require manual joins. Thank you!
