Camco Part 40631 KDF Inline Filtration Camco EVO 40631 Inline RV Water Filter

Clean, great-tasting drinking water at every campsite. The EVO inline filter connects directly to your RV water hose using standard 3/4-inch GHT fittings and uses KDF filtration media to reduce chlorine taste and odor, sediment, bacteria, and other contaminants before they reach your plumbing -- no canisters to swap, no tools required.

Better Water, Less Hassle -- At the Hookup

Campground water quality varies wildly. Some sites deliver water that smells like a swimming pool; others carry rust, sediment, or a metallic taste that lingers in your coffee and ice. The Camco EVO 40631 sits between the spigot and your RV's inlet -- filtering the water before it ever enters your tank or on-demand water heater.

The EVO's KDF (Kinetic Degradation Fluxion) media works through a redox reaction to reduce chlorine, hydrogen sulfide, iron, lead, and certain bacteria and algae. A granular activated carbon (GAC) stage follows to polish taste and capture remaining odor compounds. The result is noticeably cleaner water with no cartridges to unscrew or housings to sanitize mid-trip.

KDF + Activated Carbon

Two-stage media reduces chlorine, sediment, bacteria, and hydrogen sulfide odor effectively.

3/4-Inch GHT Fittings

Threads directly onto any standard garden hose or RV water hose -- no adapters needed for most setups.

Exterior-Rated Housing

UV-resistant canister built for outdoor campsite use. Stands up to sun, temperature swings, and repeated use.

Inline Design

Installs in seconds between the water pedestal and your RV hose. No tools, no fittings, no permanent plumbing.

What the EVO Filter Reduces

The dual-media design targets the most common campsite water complaints:

  • Chlorine taste and odor -- municipal water sources are heavily chlorinated; the KDF and GAC stages strip it out
  • Sediment and particulate matter -- catches rust, sand, and debris from aging campground plumbing
  • Hydrogen sulfide (rotten egg odor) -- KDF media reacts with and neutralizes sulfur compounds
  • Bacteria and algae -- KDF's redox action inhibits microorganism growth within the filter body
  • Lead and heavy metals -- reduced by the KDF media stage
  • Bad taste from iron and scale -- common in well-fed campsite water systems

Designed for Full-Time and Seasonal RV Use

The EVO 40631 is compact enough to tuck into a wet bay or utility compartment between uses. It is equally at home on a weekend warrior's checklist or plumbed into a full-timer's permanent hookup routine. Replace the filter after approximately 3 months of regular use or when flow rate noticeably drops.

Installation -- Three Steps

  1. Thread the filter inlet onto your campsite water spigot or the male end of your RV hose (3/4-inch GHT).
  2. Connect your RV fresh water hose to the filter outlet.
  3. Plug the hose into your RV's city water inlet as normal. Turn on the water slowly to seat the media and flush for 30 seconds before drinking.

Tip: Use a white/clear drinking water safe hose on the outlet side to keep the filtered water clean all the way to your inlet. Camco's Tastepure hoses pair well with this filter.

Flow Rate and Pressure

The EVO is rated for campground city water pressure, typically 40-60 PSI (use an RV pressure regulator upstream if your site runs higher). Flow rate through the filter is approximately 1.0 GPM, adequate for filling tanks and running appliances. High-demand simultaneous loads -- like running a dishwasher, shower, and washing machine at the same time -- may see slightly reduced pressure at fixtures, which is normal for any inline filter.

Not a Complete Purification System

The Camco EVO reduces contaminants but is not rated for purification of untreated backcountry or well water of unknown quality. For boondocking with non-potable water sources, pair this filter with a certified purification solution. This filter is intended for use with treated municipal or campground water supplies.

Maintenance and Replacement Tips

  • Replace every 3 months or after approximately 3,000 gallons of use, whichever comes first.
  • If water develops any taste, odor, or the flow rate drops significantly, replace immediately regardless of schedule.
  • Store the filter out of direct freezing temperatures when not in use -- freezing can crack the housing or damage the media.
  • Flush 1-2 gallons through a new filter before first use to purge loose carbon fines (water may appear gray briefly -- this is normal).
  • Do not reverse the flow direction; the inlet and outlet are marked on the housing.

Goes Well With

  • Camco RV Pressure Regulator -- protects your plumbing and the filter from high-pressure spikes at the hookup
  • Camco Tastepure Drinking Water Hose -- keeps filtered water clean between the filter and your RV inlet
  • Camco Rhino Flex Sewer Hose -- complete your water station setup at the campsite

Important Information -- Read Before Use

  • This filter is intended for use with pre-treated municipal or campground water only -- not for raw, untreated, or backcountry water sources.
  • Do not use on hot water lines. Cold water use only.
  • Flow is directional -- always connect with the labeled inlet toward the water source and the outlet toward your RV.
  • Do not allow the filter to freeze with water inside -- freezing will crack the housing and render the filter unusable.
  • Replace every 3 months or 3,000 gallons. Using an exhausted filter provides reduced or no protection.
  • Flush approximately 1-2 gallons through the filter before first use. Initial output may appear slightly cloudy or gray due to carbon fines -- this is harmless and clears quickly.
  • Verify hose washers are seated in all fittings before pressurizing to prevent leaks at connections.
  • A pressure regulator is strongly recommended upstream of this filter if your campsite water pressure exceeds 60 PSI.
