I am very pleased all around. The service was user-friendly and convenient. The filter arrived in a very timely way, and the product is super quality. I like receiving them every 90 days, which eliminates the need to store them. It also helps to remind me when the filter needs changing. Thank you for providing such a helpful service. I'm a delighted customer. PSW
Don't really know yet. It took so long to get it that I just installed it a little over a week ago so haven't had a chance to see how good it is. And I also received a 2nd one, one that was supposed to come in 3 months. Hope they don't keep sending them in that haphazard way.
We haven't had them long but the air quality has improved dramatically. We have to keep things closed up because it is so cold outside. The air in the house does not smell closed up or stale. Very pleased.
