Great filter, if a little challenging to install

This filter comes to you disassembled, and I confess to struggling with the build. However, Atomic Filters has a great “how-to” video on YouTube that makes this process as easy as possible. And once assembled, you’re left with a sturdy, long-lasting product.

First Class Filters.

These filters are well designed. Last year during fire season in Northern California I had the opportunity to measure the air equality inside our home vs the ambient air. These filters removed the fine particulate inside the home. I am pleased with their performance. The filters have a long life. Looking forward the the next time I purchase filters from Atomic.
