These filters tend to be on the expensive side, and the prices can vary a lot. The thing is, regardless of the price, they've both necessary and they work. I have COPD and a blood cancer. The first makes it more difficult to breathe, and the latter leaves me with compromised immunity. It's very important that the air I breathe be clean. These filters do the job nicely.
Value priced, fast shipping and well packed, great deal. we were able to use it immediately and were very pleased by the fast shipping. Item was as advertised, and was new, still factory wrapped. We have no complaints or problems with the service or product.
Good initial quality, long-term performance is yet to be determined.
This is a furnace filter which I've only installed 2 weeks ago. Filtration performance is nearly impossible to gage at only 2 weeks. However, product quality certainly meets expectations.
