any suggestions on MH water filter systems?

My verbose response:

What are you trying to accomplish? There's no single one-size-fits-all answer. Do you want high quality drinking water or just want a basic inexpensive sediment/carbon block filter? You *could* do multiple whole house filter in series and get down to around 1 micron or you could buy an inexpensive combo inline cartridge that has low flow rate and is 100 microns.

Do you want to remove some micro-organisms like Giardia and cysts? You'll need a low micron rating filter to do that. Be careful of using a carbon filter to remove/reduce chlorine as it will mean the system inside your MH downstream of the filter will be unprotected against bacteria, etc. If you want a carbon filter to improve taste, I would mount it close to the faucet you will use for drinking water.

If you want to get down to around 1 micron, the Daulton sterasyl imperial ceramic filter is interesting, but you you'll need 1 or 2 sediment filters ahead of it. It has a nominal 0.5 -0.8 micron rating and has over 2gpm flow rate. It's re-useable up to 50 times by cleaning the outer layer and will last for years. Daulton ceramic filter

Another consideration is whether or not you want/need a bacteriostatic filter so bacteria won't grow in it. Some sediment filters (like the pleated paper type) promote bacteria growth while the string-wound polypropylene type won't. The Daulton ceramic filter has silver in it and is bacteriostatic.

You should pay attention to flow rates of filter cartridges, some have low flow rates and you may not be happy. I would aim for 2-3 gpm and 5gpm or more would be good. Generally speaking, the physically large a cartridge is, the better the flow rate. Better flow gives lower pressure drop too.

While you are considering filtration, I would think about installing a Watts regulator inside your MH like the 263A model which has good flow rate. Then just use a Valterra high pressure hose to your water inlet.

If you install water filtration on the city water inlet side of your system, you'll have no filtration for your holding tank. It'd be possible using some valves to make it possible.

It may depend also on where you intend to travel to. Water quality in some areas is not good. Sometimes you can also be on well water in a CG and the water quality can be suspect.

I'm about to install a 4 stage filter system in our TT using 2 sediment filter, the Daulton ceramic filter and then a UF (ultra filtration) filter. The UF filter is 0.2 microns and will be used for just drinking water at the kitchen counter using an RO type faucet. Everything except the kitchen sink will just have sediment filtration. All the 10" filter housings will fit nicely under the kitchen sink. A UF filter is used in bulk water dispensers in grocery stores and will provide good quality drinking water and does not remove minerals like a RO system does.

The Culligan filter is a kind of "entry level" filter and low cost. It's "only" 1 gpm. They don't say what the micron rating is but I'd guess it's something 100 microns. Keep in mind that a small filter like this that has low flow rate to start with, will only get slower and slower as sediment gets deposited inside. It's bacteriostatic (uses KDF) which is good. There is very little tech. data on it. Note that it is rated for max. 100 deg. F. You should use a inline pressure regulator ahead of this filter. Inline regulators also have low flow rates.

So the answer to your question is - it depends...
