Buy the $34.99 Camco TastePURE if your problem is how campground water tastes. Buy the $599.99 Clearsource Ultra if your problem is what might be in it. These are not two grades of the same product; they do different jobs, and most of this page is explaining that difference. Scores weigh published specs, warranty, and price. We have not lab-tested these units.

Micron ratings, in one paragraph
A filter's micron rating is the size of particle it physically stops; smaller numbers stop smaller things. The Camco inline is rated at 20 microns, which catches sand, rust flakes, and visible sediment. The Clearsource Ultra and the Beech Lane both run a 5-micron sediment stage into a 0.5-micron carbon block. That 0.5 figure is 40 times finer than the Camco, and it is the difference between screening a hose and actually filtering water. Nothing about the Camco is dishonest; a 20-micron sediment screen with carbon behind it is exactly what a $35 inline filter should be. It is just a different tool.
What carbon does and does not do
Every filter here uses carbon, and carbon has one core talent: adsorbing chlorine, tastes, and odors. That is why an inline Camco makes municipal campground water drinkable-tasting. What loose carbon media does not do is strain out fine particles; that depends on the physical pore size, which is why the solid 0.5-micron carbon blocks in the canister systems matter. And no carbon stage, block or granular, sterilizes water. Of the three, only the Clearsource's VirusGuard stage even claims bacteria, cyst, and virus reduction, and Clearsource does not publish a micron rating for that stage. Whatever you buy, start from a potable source. The filter is insurance, not treatment.
Where the Camco claims actually live
One honesty note before the table. Camco's SKU page for the TastePURE lists price, dimensions, and warranty, and nearly nothing else. The specs everyone shops on, the 20-micron rating, the 120-day lifespan, the NSF/ANSI 42 and 53 testing and NSF 372 lead-free claims, all come from Camco's TastePURE marketing pages rather than the product listing. We are reporting them as claims, and flagging where they came from, because that is the kind of detail that should be on the product page and is not. Clearsource has a milder version of the same issue: the roughly 2,000-gallon cartridge life is site content we found via search, not a product-page spec.

Who should buy what
Weekenders at developed campgrounds: the Camco, and stop thinking about it. The water is municipal, your complaint is chlorine, and $35 a season fixes it with zero installation.
Full-timers filling wherever the tap is: the Clearsource Ultra. Fine sediment staging, the 0.5-micron block, a claimed 4.5 gpm so your pressure survives, and a metal chassis built to live outside. $599.99 is a lot of money; seventeen seasons of Camco filters, by the math. Whether that trade makes sense depends entirely on how much you trust your water sources.
The Beech Lane is the interesting maybe. Same 5-micron and 0.5-micron staging as the Clearsource, lead-free brass, a claimed lifetime warranty, bracket and filters included. But the manufacturer site shows no price and simply links to Amazon, and it publishes neither a flow rate nor a cartridge life. If the Amazon price is right on the day you look, it may be the value pick. We cannot tell you that in advance, and we will not guess.
What we would skip
Buying the Clearsource for a rig that only ever fills at well-maintained campgrounds; it is solving a problem you do not have. And buying the Beech Lane without checking the current Amazon price and searching out replacement cartridge costs first, because a canister system with unknown consumable pricing is an open-ended subscription.
