I just had a new 4-ton tranquility 30 closed loop installed(I wanted a water furnace series 5 but long story).

Model SET048AGDD0SPVS

Came with 2- 15.5x29.5x2 filters

I can’t find any reliable information for the stock filter replacement. I can visibly see ~1” gap on the top of the filter housing and see the heat exchanger.

The 2 filters are stacked, resting on top of one another, no support rail. Seems a little beat up from initial install.

Can/Should I swap with a single 30x32x2? Rough measurements it should fit.

Are there any HVAC people here with any input? Anything I should worry about morning can fit it in there should I be good to go?
