How it works - Inline Water Filter 15mm

The Osmio filter housings with buttress threads for 9-3/4 in. filter cartridges are made from NSF and FDA grade materials, manufactured from the highest quality, FDA grade, 100% polypropylene and acrylic styrene. They have a leak-proof sealing is accomplished by compression against a top seated EPDM o-ring located in the housing’s sump. Thick wall and added ribs make the housings ideal for a wide range of applications. Polypropylene construction provides excellent chemical resistance with most acids, alcohol, ammonia, oils, plating solutions and many aggressive chemicals. 


The Osmio EZFITPRO-100 Inline 15mm push fit water filter system has the following dimensions:

A: 325 mm

B: 122 mm

C: 107 mm

Dimensions of Water Filter 15mm Inline

5 Micron Carbon Block

The Osmio Carbon Block filters use coconut carbon filtration technology to maximize the carbon capacity and prevent channelling whilst maintaining a low pressure drop leading to more efficient water filtration.

The filter is a compatible replacement water filter cartridge for similar 10" filter housings including brands such as Pentek, Ametek, Culligan, Whirlpool and so on. It will fit all under sink water filter housings which use a standard size small 10" x 2.5" filter replacement cartridge.

Product Questions

Does it remove farm pesticides
Question by: Bill on 12 Jul 2021, 15:04
Yes, carbon will do pesticide reduction. Effectiveness will depend on influent levels. If you are on the private water supply - please get in touch with us as we need more information to recommend a suitable system.

Hi, how do you change the filter? Do you need a plumber or is it laymen friendly. Thank you, Emma
Question by: Emma on 2 Apr 2022, 10:15
Hi, you do not need a plumber to change the filter.
1. Turn off the water supply to the filter and tap & open the tap to release the water pressure, leave the tap open.
2. Unscrew the filter bowl from the housing with the spanner provided.
3. Check & regrease the o-ring with plumber's silicon grease.
4. Insert the new filter, replace the housing bowl & retighten (being careful not to overtighten).
5. Turn the water supply back on & flush for 5 minutes.
6. Close the tap and adjust the pressure release screw on the system to release any air, a little bit of water will come out, then fully tighten the screw.

Hi, just wondering if this filter removes BPAs? I will have a plastic water container in my van and I don't want to ingest a load of plastic! Thank you :)
Question by: Alisha on 22 Apr 2022, 17:13
The carbon block filter in the EZfit Pro 100 system will reduce BPS and BPA, but the level of reduction will depend on contact time and influent level (how much is in the water drawn from the tank). Ideally, for 99% reduction of BPA we would recommend reverse osmosis, such as the Osmio Zero.

Does installation require a plumber?
Question by: Ali on 4 May 2022, 05:20
This depends on the DIY skills, it is straight forward to install - please see manual under section ''files'' under product description.

Hi does it remove PFAS
Question by: Mark Cawley on 12 Dec 2021, 22:46
Thanks for your question

Activated carbon is capable of reducing PAFS, to some degree, but the level of reduction achieved with Activated carbon will depend on many factors, like, the concentration of chemicals in the water and the contact time between the water and the filter etc.

Reverse Osmosis technology would be the most suitable method of PFAS reduction, with reduced levels of typically 93-96% reduction.

If you are concerned about the levels of any particular contaminant the only way to be sure of the exact level of reduction is to check the influent and effluent of the filter system over a period of time getting both tested at a laboratory.

We offer Point of use Reverse Osmosis systems, Please see the link below.
