Depends on water source for filter requirements.Fla, South Ga, La,Michigan needs lots filter capacity. The worse the water the more filter capacity required.
Th better the filter, the more they cost and the more frequent you have to replace them.
N way to cheat the situation.
A large whole house 10 inch filter housign with remote sensor to let you know it is full cost about 70,00 at Home Depot for GE or Lowes for Culligan. The less expensive 25 micron KDF filter of them will get just about all sediments and many bugs. Buy the filters on.25 micron kdf filter when if f lien and save.ng
Higher spec filters for those housings are available on line, and the variety confusing. Replace the large filter when led shows. A somewhat to a lot more expensive .5 micron or whatever,spected to get all the bugs won't have to be replaced so often.
In Michigan the well water at numerous campgrounds especially when the campgrounds are full will load up a filter in no time, like one day, if you wash clothes.
South Georgia, Louisiana, had .9 micron ceramic filter with a pre filter stop up in two days with stinky black and yellow sulfur and iron.
Those inline Camco filters load up fast and then everytime you turn on the tap flush sediment right past it and into your glass or shower, in Michigan per example.
Right now here in the desert we have just a half micron, high spec cartridge in small 10" housing. Cost was about 47.00. Don't remember the number right at the moment. But...nothing much gets through the filter, and the source has lots of calcium and magnesium, I think, but virtually no sediments.
All the KDF filters get the chlorine out of the water, I think, so I put some drinking water chlorine in the fresh water tank, and no taste if not too much is used.
No need or desire to buy bottled water with a shot of ozone in it to aggravate the palate.
On edit: I remember several years ago at a favorite campground in Michigan, a camper next to us, in conversation I showed him the sediment, mud, in clear filter housing. He said they didn't drink it but just showered and washed clothes in it. They drank bottled water.
His white t shirt and socks were a decidedly unlovely hue of yellow/brown. And his "tan" too.
