I bought two air filters from them
I bought two air filters from them, and one of them is producing an oily smell when I install it and run my air filter. I asked for a replacement and was told to return it at my cost and that there would be a restocking fee since I already used it. Total garbage service, and unlikely a real HEPA product. I'm pretty sure the quality standards of producing a real HEPA product, which is supposed to filter impurities, includes making sure that you do not sell the HEPA filter with an impurity on it.
