Shower Filter Frequently Asked Questions

This depends on the type of shower you have and how you want to fit your shower filter. The three main methods of fitting a shower filter are :

1. The hand held shower filter: This simply replaces your existing hand held shower head that is attached to an existing shower hose. connecting-shower-hose-to-head-graphite-pencil
2. The in line shower filter: This simply fits between the shower water outlet pipe and either your shower head or shower hose. So you keen your existing shower head or shower hose and just install this shower filter in line / in between. connecting-shower-hose-to-head-graphite-pencil
3. Fixed pipe shower filter: For this one you just remove your existing shower head from the fixed pipe and then replace it with one of our fixed head shower filters (Paragon Luxury Fixed Shower Filter Head , Paragon Luxury Rainfall Shower Filter) . Just remember to remove the shower head entirely and expose only the shower pipe and threads.


You can find all our products and how to install them on each product page. Or if you wish you can send a picture to us at and we can try to help you further.

If you have normal water pressure don't worry, you shouldn't notice a difference.

If you have low water pressure you could try one of the AquaFilter™ products (Large Head Hand Held Shower Filter, Extra Large Head Hand Held Shower Filter) these have a smaller cartridge and as such work better in low pressure environments. Though please keep in mind with low pressure, you might encounter a drop after installing a shower filter.

Our shower filters remove or reduce a great number of impurities, some of the major ones include: Up to 99% chlorine, heavy metals, scale, kills bacteria, pesticides, trihalomethanes (THMs) & chemicals. It works just like a drinking water filter but in your shower.

The main ingredient in all of our shower filters is KDF® 55 this filter media is patented and removes or reduces chlorine and water-soluble heavy metals. It controls scale, bacteria and algae, even in hot water. The process medium received NSF International Certification and is certified by NSF to NSF/ANSI Standard 42 – Drinking Water Treatment Units – Aesthetic Effects. This medium is also in compliance with California’s Health and Safety Code Section 166875 (or commonly know as AB1953) and Vermont Act 193

Many of our shower filters also incorporate Granular Active Carbon (GAC), which is the standard in most water filter devices. GAC is a well proven filter medium and has been used in water filtration for decades to remove organic compounds, synthetic organic chemicals and adverse taste and odor compounds. You can read more about GAC here.

By themselves, both of the above filter mediums are great - but when combined into a single filter unit, they work to give the highest level of filtration.

The AquaFilter™ range of shower filters incorporate ceramic ball technology (rather than GAC), combined with KDF® 55 to provide an excellent degree of water filtration ability.

No, you just need to change the cartridge inside the shower filter.

Cartridges last usually between 8 - 12 months, depending upon usage and the quality of the water in your area.
For the AquaFilter™ products the cartridges last between 3 - 6 months (again depending upon how much you use it and the quality of the water in your area). But the refill packs are sold in two cartridges, so a refill will pack will last between 6 - 12 months.

Cartridges need to be changed at least once every 12 months. It is based on time, usage and the quality of the water in your area. But we offer a free reminder service which sends our customers a reminder e-mail when it is close to their time to change a cartridge.

Yes all of our shower filters come with a cartridge already installed.

Our shower filters will fit all standard showers. 99% of Showers in the UK and Europe conform to a thread size of 1/2 inch BSP (British Standard Pipe). So it's pretty much certain that our shower filters will fit your shower.

For the Hand Held Shower Filters, they will fit onto the great majority of shower hoses. If you have a shower hose, then we're quite certain our shower filters will fit.
For in-line shower filters, the pipe size (also known as thread size) is 1/2 inch BSP.
When measuring with a ruler the diameter is roughly 22mm.

If you wanted to install an in line shower filter but your water pipe is very close to the wall and you're worried about having enough room to fit a shower filter. Then we would recommend the 8 Stage Shower Filter, this shower filter can be installed on an angle with the body of the shower filter angling away from the pipe. Also the water inlet pipe can be tightened independent of the shower filter body.
We also offer an Angle Pipe adaptor, you can find it here :
