Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For a water filter, safety means named certifications, lead-free components and food-grade materials the listing actually states; a filter that states none scores zero on that line, whatever its capacity. Only the Camco listing states a warranty term, and only the Camco listing states NSF and CSA certification. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Camco Tastepure XL RV Filter | 9.7 | 32 | 22 | 21 | 9 | 3 |
| AQUA CREST RV Inline Filter | 9.6 | 30 | 21 | 21 | 8 | 0 |

Scores start at 9.2 for the lowest totals and top out at 9.8. In between, a kit’s position follows its weighted points one to one in order.
How to choose the best rv water filter for sulfur smell
Look for sulfur reduction stated, not implied
The H&G listing names sulfur odor and rotten egg odor directly, and the AQUA CREST listing names hydrogen sulfide among the substances it reduces. The Camco listing speaks of odor in general, with no sulfur compound named. If sulfur smell is the reason for the purchase, a listing that names sulfur or hydrogen sulfide gives a clearer match than one that only mentions odor.
Certification and media
The Camco listing is listed to NSF/ANSI 42 and 53 with CSA lead-free certification to NSF/ANSI 372, and the AQUA CREST listing is certified against NSF/ANSI 42 and 372. The other listings state GAC and KDF media without a named standard. A 20-micron filter is stated by the Camco, GLACIER FRESH and Hourleey listings, and the FRIZZLIFE listing in the more picks states a 0.5-micron filter.
| Filter | Media | Certification | Capacity |
|---|---|---|---|
| Camco Tastepure XL RV Filter | 6-step, GAC and KDF | NSF/ANSI 42, 53, 372 | Not stated |
| AQUA CREST RV Inline Filter | KDF and carbon | NSF/ANSI 42, 372 | 3 months |
| H&G RV Water Filter System | 2 kg GAC, 1 kg KDF | Not stated | 300,000 gallons |
| GLACIER FRESH RV Water Filter | GAC and KDF | Not stated | 3 months |
| Hourleey RV Inline Water Filter | GAC and KDF | Not stated | 3 months |
Capacity and service life
The H&G listing states up to 300,000 gallons, while the GLACIER FRESH, AQUA CREST and Hourleey listings state a service life of three months. A stated capacity in gallons suits a long stay, and a stated service life in months suits a season. See our guide on how long a water filter lasts before planning replacements.
Fittings and hose protectors
The H&G listing states a 3/4-inch GHT adapter, and the AQUA CREST listing states the filter attaches to any 3/4 GHT standard water hose. Every 2-pack here includes flexible hose protectors, and the AQUA CREST protector rotates 360 degrees. Keeping the tank clean matters too; see our guide on how to clean an RV water tank.
Sizing Notes
- Match the fitting to the hose: 3/4-inch GHT is the stated size on the H&G and AQUA CREST listings.
- Match the media to the smell: GAC and KDF are the stated media across this group, with sulfur odor named by the H&G listing and hydrogen sulfide by the AQUA CREST listing.
- Match the service life to the stay: 300,000 gallons stated for the H&G filter, three months stated for the GLACIER FRESH, AQUA CREST and Hourleey filters.
- Match the flow to the hookup: 0.5 gpm is the only flow rate stated, on the AQUA CREST listing.
FAQ: power away from the grid
How do I change an RV water filter?
The AQUA CREST listing states installation by hand in 5 minutes with no tools, attaching to any 3/4 GHT standard water hose. The Hourleey listing states the same no-tools hookup: connect the incoming hose to the filter following the water flow direction, then attach the outgoing hose to the RV.
How do I use an RV water filter?
Attach the filter to the hose between the hookup and the RV, following the water flow direction stated by the Hourleey listing. The Camco listing states the filter attaches to any standard garden or drinking water hose.
What is the best RV inline water filter?
For sulfur smell, the H&G listing names sulfur odor directly with a stated capacity of 300,000 gallons, while the Camco listing carries the fullest certification in this group. The right pick depends on whether the sulfur smell or the certification matters more.
Do RV water filters work?
The listings here state what each filter reduces: the GLACIER FRESH listing states 97.9% chlorine removal, the H&G listing states 99% chlorine removal, and the Camco listing states a 20-micron sediment filter. A filter works on what its listing states, so match the stated reductions to the water at the hookup.
What is the best RV water filter?
The Camco Tastepure XL leads this group on certification, with NSF/ANSI 42 and 53 listing and a Limited 1 Year warranty stated. For sulfur smell specifically, the H&G listing names sulfur odor directly.
