Aquahot air filters

[gnlandrus]

Anyone know I’d there are any return air filters in the Aquahot furnace system. I have searched high and low and can’t find anything! I find it hard to believe there isn’t any air filtration in the system someplace !

I've never seen one.

being it is a heating coil only and not an evaporator coil as in an A/C filters or not needed. But it does not hurt to vacuum the fan coil if you can get to it.

I remember reading about cutting filter material to fit behind the resisters.

Don’t believe there’s anything other then cleaning off the heat exchangers. Will attach a manual, maybe it will help. Can’t get it to attach. Can email but need a address.

Thanks everyone!
I sure couldn’t find any filters! I will have to remove all the grills, and use my shop vac to clean them out, and maybe try to cut some filter material to insert behind the grills to catch large particles. I understand it’s important not to restrict the air flow so I will keep that in mind.
Guess my best option is to keep using the hepa air filter unit I bring from home.
Cheers!

We use rolls of stuff like this this at work if you scroll to bottom there are many "like this". I have seen furnace filters that use it , you might get one in a store and cut apart. But any filter media will reduce air flow , exaggerate by low pressure fans. The larger intake area you can create to filter the better.
