FRIZZLIFE MV99 RV Inline Water Filter: features, specs and fit

The FRIZZLIFE MV99 is an inline water filter that connects between an outdoor tap and the hose feeding an RV, camper or boat. It is built to filter the water as it enters the vehicle, rather than at a single drinking tap. This page covers what the listed specs mean and what to check for your setup.

How an inline hose filter works

An inline filter sits on the fill hose. Water passes through a filter cartridge on its way to the RV's plumbing, so everything downstream receives filtered water. FRIZZLIFE says the MV99 is larger and sturdier than traditional RV hose filters, with a service life it puts at two to four times longer, and that it maintains good flow at high water pressure.

What the carbon block and 0.5 micron figure mean

The cartridge uses a composite activated carbon block with a filtration accuracy of 0.5 micron, which describes the size of particles it can catch. Activated carbon is typically used to reduce chlorine, which affects taste and odour, and a fine block also traps sediment. FRIZZLIFE lists chlorine, sediment, lead and other heavy metals, bad taste and odours among the things it reduces. Actual results depend on your source water, and no filter addresses every concern. If you have specific worries about a water source, check local guidance.

NSF/ANSI 42 and 53

FRIZZLIFE states the MV99 is certified by IAPMO R&T against NSF/ANSI 42 and 53. Standard 42 covers aesthetic effects such as chlorine, taste and odour. Standard 53 covers health-related contaminants, with each certified product tested against specific claims. Look at the certification documents for exactly which reductions are covered.

Fittings, installation and holder

The connection fittings are lead-free brass, and FRIZZLIFE says they fit standard 3/4-inch garden hoses. The package includes what is needed for installation, and the brand says it takes about five minutes with the manual and an installation video, with no plumber needed. A filter holder with metal pegs keeps the unit upright on the ground, which helps avoid hose kinks. The unit can also be mounted on a wall with the supplied screws. FRIZZLIFE also mentions an optional PRV02 pressure regulator, sold separately, to protect the system from high-pressure outdoor sources.

Changing the filter

The MV99 has an auto shut-off design, so you do not have to turn off the water supply when changing the cartridge. The cartridge twists in, and FRIZZLIFE says it can be replaced in about three seconds. Only the inner filter core is replaced, so the plastic housing is reused. The replacement model named in the listing is the FZ-2. How often to change it depends on how much water passes through and its quality, so follow the manual.

Cold weather and storage

Water left inside a filter can freeze and damage the housing. In general, filters should be drained and kept indoors, or removed, when temperatures near freezing are expected. Check the manual for FRIZZLIFE's guidance.

Who it suits

It suits RV owners, campers, boaters and gardeners who connect to a hose at campgrounds, marinas or home and want filtered water on board. The listing also mentions uses for cleaning, dishwashing, cooking and a car rinse.

What to check before you buy

• Thread size: confirm that your hose and the RV inlet use standard 3/4-inch garden-hose threads.
• Space and weight: the unit weighs 6.2 lb, so check it fits where you plan to stand or mount it.
• Pressure: consider a regulator if you connect to high-pressure supplies.
• Replacement cartridges: note the FZ-2 model and how often you will need to change it.
• Certifications: read the specific claims behind the NSF/ANSI listing.
• Cold climates: plan how you will drain it and keep it frost-free.
