Now more than ever Im relieved that such a great product is available at an affordable price. My parents are elderly and my mother has breathing issues. In my mind its one less thing to worry about.Thank you for your great product and service!
I was recently having problems with our furnace shutting down and starting up right away. The furnace tech recommended I change the filter. He also found a cracked air tube end. I ordered 4 replacement filters which were fairly costly. I had them 2 days later. I put a new one in and it seems to have solved the problem.
The filters are for backup and won't be used for some time. I have a good filter in my furnace now but purchased it elsewhere so can't give a rating on the filter itself but the on line purchase went well and was done in a timely manner.
