New filters for an older system
on October 3, 2023

Can recommended by our HVAC service person for our home unit. With 3 dogs, a cat, and hardwood floors throughout the house we needed a quality filter that is not too thick to over work our system. We change our filters every 60 days when system is running continuously.

Filters were sent "actual" size
on October 1, 2023
Posted by: Anonymous
Filters were sent "actual" size and NOT nominal size. I can only use filters that are closest to nominal size. These filters are too small for my vent and actually have gaps in the spacing at the vent. Obviously not good enough to "capture" all the airflow thru the filters !! ouch ! My old Filtrete filters "fit the bill" in its sizing with vent! I really can't use these filters!Thank you for allowing comments...

Haven't used it yet so I can't comment on protection and dust. It appears to be well constructed. The price is bit high but I thought I would give it try on performance. I usually replace every 60 days so I'll see itf it holds up
