Standard web store. Easy to understand info and really competitive pricing. No way to measure efficiency or reliability of filters outside of given info. Same with any store selling non-name brand filters.
Very easy to set up, filter shipped fast, and now I can just change it every time a new one shows up. Great product and great service. Highly Recommended!
As soon as these were installed, the air began to feel crisper&cleaner, it even smelled fresher in the house.They seem to work very well.I am So Happy!!Thank You.
