Trust this company

I ordered the 2 pack of Merv #10 x6673 from for so very much less than if I were to have got them here in Denver. I received them within 3 days. Very happy and will not hesitate to use company again and again for my filter needs.

Lennox X6673

I can't believe how easy it was & it was very clear. The cheapest price I have seen among different webistes & same quality I hope. I was able to even take the advantage of some promotion as well. I would prefer to other friends & families.Great work!! Ke

Great company to do business!

I have been ordering the Lennox Merv 10 Cat. # X6673 from for several years. Naturally the tightwad I am, I always review the "competition" and I always return to The Hough Company makes it so eazy to complete the order
