Today’s review features the Propur ProMax 4-stage shower filter.
According to Propur, the filter removes 200+ contaminants that might be lurking in your shower water, protecting your skin and hair from their unhealthy effects, and improves water odor and taste (in case you get thirsty).
What’s more, no cleaning is required, because the filter cartridge contains neither resins nor beads, but instead makes use of micro-pore filtration technology.
It’s rated at 2 gallons per minute flow rate which is adequate and you can choose between 3 different finishes:
They all come with a ProMax massage head, although the chrome version is also available with a handheld wand or a dual-head setup (handheld wand + overhead shower head).
All heads offer 5 different spray settings for the highest comfort.
What we like about the ProMax shower filter is the fact that it was thoroughly tested (not certified) against NSF Standard 42 + 53. Here is an excerpt of the lab report:
The filter reduces or removes
As you can see, the filter is NOT perfect for all types of contaminants, heavy metals in particular. This is also why Propur advised against the use with microbiologically unsafe water without adequate disinfection.
All in all, the filtration performance is solid when compared to other shower filters on the market.
Other pros are that the filter provides great pressure, is made from BPA-free plastic, and the 1-year limited warranty on the assembly respectively 9 months on the filter cartridges.
As with most shower filters, installation is simple and straightforward and shouldn’t take more than a couple of minutes, provided that everything goes as planned (see below). Just follow these instructions:
By the way, the filter fits ½” standard pipe threads.
As with the installation, replacing filters is a quick and easy process:
Filtration capacity: Up to 6-9 months.
Here is a link to the manual.
Leaks, leaks, leaks. Leaking is the biggest issue with the Propur ProMax by far. The filter might leak where it connects to the shower arm. This is mainly due to a loose thread connection which may also cause the filter to spin, blow off, or not fit at all – no matter how much Teflon tape you use.
Or the filter compartment itself might leak. You can try checking the O-rings to make sure that they are properly seated, lubricate with food grade silicone and tighten the housings, but it might not help.
We also don’t like that there have been too many incidents where the plastic cracked, especially considering the high price.
Speaking of, replacement filters are a bit more expensive that what you pay with the competition.
We would have rated the Propur ProMax with 4 stars or more if there weren’t these issues with leaks, loose thread connections and cracking. After all, the filtration performance is really good for a shower filter. Anyway, it is what it is, so 3.5 stars from us!
