Does this housing comes with the two O rings?

Yes the filter came with the O-rings and the mounting plate along with screws to mount the bracket to the top of the black lid that the housing screws into. Also the unit comes with the appropriate lubricating grease for the O-rings and it is strongly advised that the installer uses this grease on the entire O-ring surface to prevent tearing of the O-ring while tightening the housing.

Where can I get the o-rings for this housing?

The top one is Pentek 151122. I have not been able to find the 6" side o-ring. Maybe the Pentek 151122 can stretch to fit? Not sure. I think the side o-ring isn't that important, the top one is doing all the work.

Are threr any cartridge type filters that will remove TDS from water to use in a humidifier?

Buy a R/O if you want water specifically for the humidifier

We have very hard water which deposits calcium and lime in out electric water heater will this product help on the cold water input to the tank?

This filter will only remove sediments such as dirt, rust particles, etc which are larger than the pore size of the filter cartridge. Calcium and magnesium are dissolved minerals. I’d suggest a water softener. I use the Fleck 5600SXT which does a good job. I use the Big Blue 20” filter inline before the water softener
