Shower filters

Researched and approved by Sebastian, 10 years in water filtration and softening · Last updated 4 August 2026

A compact filter fitted between the shower arm and the head, aimed at chlorine and its effects on skin and hair.

A shower filter screws in between the shower arm and the head, or in-line on a hose. Most use a mix of media — KDF, calcium sulphite, activated carbon — targeted at chlorine, which is the main reason people buy them.

The reported benefits are less dry skin, less irritation and better-behaved hair, and there is a plausible mechanism: chlorine strips natural oils, and hot water opens pores and increases exposure. Plenty of people report a clear improvement. It is not a rigorously evidenced claim and this site will not present it as one.

What a shower filter does not do is soften water. This confusion is actively encouraged by some product marketing that talks about 'hard water shower filters'. If your problem is limescale on the screen and in the head, only a softener addresses that.

Best for

  • Chlorine sensitivity
  • Dry or irritated skin after showering
  • Anyone in a heavily chlorinated supply area
  • Renters who cannot fit anything permanent
Suitable for homes Suitable for commercial premises

Used in gyms and salons, though a whole-property solution is usually more sensible at that scale.

Cons

  • Does not soften water, whatever the packaging implies

Can you install it yourself?

Yes, this is a realistic DIY job

Skill level: Easy · Time: about 10 minutes

Unscrew the head, wrap the thread with PTFE tape, screw the filter on, screw the head onto the filter. Run it for a minute before use.

Tools you will need

  • PTFE tape
  • Possibly an adjustable spanner

Maintenance

Every six months, or sooner with heavy use.

Replacement interval: roughly every 6 months, though volume matters more than time. More on cartridge intervals.

Frequently asked questions

Do shower filters work for hard water?
Not in the sense most people mean. A shower filter reduces chlorine, and many people find that helps their skin and hair. It does not reduce hardness, so you will still get limescale on the screen, on the head and in the shower tray. Only a water softener changes that.

Carbon filters

Activated carbon cartridges that adsorb chlorine, organic compounds and the things that make water taste and smell wrong. The workhorse of domestic filtration.

Softeners

An ion-exchange unit plumbed into the rising main that removes calcium and magnesium entirely, giving genuinely soft water throughout the property.

Scale inhibitors

A compact in-line device that changes how hardness minerals behave so they do not stick as scale, without removing them. Far cheaper and simpler than a softener.
