Camco TastePURE Camper/RV Water Filter, Inline, Reduces Bad Taste, Odor, Chlorine and Sediment, Made in USA, 4-Pack (40042) Review (2026)

What GAC and KDF filtration removes

Each filter in this 4 pack combines granulated activated carbon, commonly called GAC, with KDF filtration media in what Camco calls its Hex-Flow six-step filtration process. GAC is effective at reducing chlorine taste and odor along with some organic compounds, while KDF media is included specifically to help control bacteria and mold growth inside the filter housing when it is not actively in use between trips, which is a common weak point for simpler carbon-only filters that can host bacterial growth if left wet and idle in storage between camping seasons or shorter weekend trips out on the open road.

Certifications and made in USA

Camco states these filters are independently tested and listed to NSF/ANSI 42 and NSF/ANSI 53 standards, which are recognized certifications covering aesthetic contaminant reduction like taste, odor and chlorine, and health-related contaminant reduction respectively. The filters are also CSA lead-free content certified to NSF/ANSI 372, and Camco lists them as made in the USA, which is a detail some buyers specifically look for in water-contact products compared with imported alternatives that may not carry the same level of independent certification testing behind their manufacturing and materials sourcing, giving a clearer paper trail overall.

Wide-body design and flow

The filter uses a wide-body housing rather than a narrow inline cartridge, and Camco states this design is meant to increase water flow through the filter media compared with a slimmer housing, which matters for filling an RV fresh water tank or running the city water connection without a noticeable drop in pressure at the faucet or a slow trickle at the kitchen sink. Each filter measures about 11.13 inches in height and connects with standard garden hose or drinking water hose threads, so it installs inline between the spigot and the RV's fresh water hose without extra fittings or adapters needed in most standard campground hookup setups at any given site.

Why buy a 4 pack

Camco also sells this filter as a single unit and in other pack sizes, and buying four at once brings the per-filter cost down compared with repeat single purchases through a camping season, which matters since these are consumable filters meant to be swapped out periodically rather than cleaned and reused indefinitely. For a family that camps frequently or a full-timer filling up at many different campgrounds with varying water quality, having spares on hand also means never being caught without a working filter mid-trip while waiting days for a mail-order reorder to catch up at the next stop further along the planned route.

What this pack leaves out

Camco's related 40043 single-filter listing includes a flexible hose protector accessory alongside the filter, which helps take strain off the hose connection point and keep the fitting from twisting under the hose's weight, but this 40042 4-pack listing does not include that protector, so anyone who wants it will need to source it separately or reuse one from a prior single-pack purchase. That is a minor omission rather than a functional downside for the filter itself, since the core filtration performance and certifications are the same, but it is worth knowing before assuming the 4 pack matches the single listing feature for feature down to every included accessory that ships in the box with the filters themselves.
