Media Air Filter-Help

[allan403wood]

I was wondering if anyone had any experience with Ultravaison Media Filters. Specifically, how do they compare with Trion AirBears?

Also, what is the nest way to determine whether to use a 4" or 5" filter. I have a 5-ton system.

Thanks.

Use whatever fits. A 5" will last a little longer than a 4". Not sure about the brands you mentioned. I'd stick with a MERV 8 rating.

I would go with Trion over Ultravation any day!
