Filter confusion
on October 1, 2020
Posted by: Therese M.
I think the filters are great and although the package says it's merv 13, this is not marked on the filter itself. I plan to buy several types of filters and won't know which is which unless I write on the filter.. suggest adding this info directly into each filter.Thank you!

Great product. With the smoke from wildfires we needed more frequent filter changes. One look and one could see they are doing their job. New on the left, 2 months old on the right.

We are in the fire

We are in the fire area with tons of smoke. I have hooked up some filters on a couple of box fans to work with the house air system to filter the smoke out of the house. They are doing a great job.
