Great Filters

Our air conditioning system takes an unusual size filter. The filter was custom sized and fits perfectly

Very satisfied with purchase

Filter king had the exact size I needed that couldn't be found at a big box store. Great price, quality and service.

Perfect, odd size filters

I needed some odd size filters, and these work perfectly in my old boiler heating system blowers. Shipping was prompt and I will definitely buy these filters when I need them again.
