Better filter efficiency.

Right product at the right price. I live along a heavily traveled bus route so I use them on my room filtration units between filters to capture dust and hydrocarbines

Not Much to Screw Up But....
By Placeholder on Reviewed in the United States on November 17, 2024
Simple pre-filter. Came folded unevenly and creased. Don't need them immediately so laid them flat with weight on them. They'll probably work fine but clearly not on par with others I have ordered from others previously.
