Everything You Need to Know

Every detail of the TENAX Hard Water Shower Filter is worth knowing. Here's a closer look...

15-Stage Multi-Layer Filtration +

Each cartridge contains 15 distinct filtration layers
Each layer targets a different category of contaminant
Chlorine, sediment, rust, heavy metals, microplastics, and odour are all addressed
The layered approach catches what single-stage filters miss

Spiral Flow Design +

Standard filters push water straight through the centre of the cartridge
The spiral design distributes water across the full width of every layer
Every filtration stage gets even water contact
More consistent, more thorough filtration per cartridge

KDF-55 and Activated Carbon +

KDF-55 is a copper-zinc alloy that targets chlorine and heavy metals through a chemical reaction
Coconut activated carbon absorbs odour, taste, and organic compounds
Together they handle both the chemical and particulate side of water quality

Tool-Free Installation +

Unscrew the existing shower head from the arm
Wrap Teflon tape around the shower arm thread
Twist the filter on by hand
Reattach the shower head to the bottom of the filter
Flush for 20 seconds, done

4-Month Cartridge Life +

Each cartridge lasts up to 4 months with daily use
When the water flow slows or the filter reaches the 4-month mark, swap it
Twist off the housing, pull out the old cartridge, drop in the new one
No tools needed for replacement either

Frequently Asked Questions

Does it reduce water pressure? +

No. The filter is designed to maintain normal water pressure. There is no noticeable drop in flow during use.

Does it fit any shower head? +

Yes. The universal G1/2" connection fits standard shower arms and handheld hoses. The existing shower head reattaches to the bottom of the filter.

How hard is the installation? +

Simple. Wrap Teflon tape, twist the filter onto the shower arm by hand, reattach the shower head, and flush for 20 seconds. No tools, no plumber, under 5 minutes.

Can a difference be noticed from the first use? +

Yes. Visibly clearer water and reduced chlorine odour are typically noticeable from the first shower after installation.

Does it remove all contaminants? +

The 15-stage system reduces chlorine, sediment, rust, heavy metals, microplastics, and odour. It is not a water purifier and does not make non-potable water safe to drink.

Will it reduce my water pressure? +

No. The filter maintains a flow rate of 8 litres per minute, so water pressure stays strong even with the filter in place.

How long does the filter cartridge last? +

Each cartridge lasts up to 4 months of daily use, or approximately 50,000 litres. This will vary depending on water quality and household usage.

How do I know when to replace the cartridge? +

If the water flow starts to slow down or the water begins to smell or look different, it's time for a new cartridge. As a general rule, swap it every 3 to 4 months.

How do I replace the cartridge? +

Twist open the filter housing, remove the old cartridge, drop in the new one, and close it back up. No tools needed. Takes less than a minute.

Is it safe for all skin types? +

The filter is designed to reduce common irritants like chlorine and heavy metals from tap water, making the water gentler for everyday use across the whole household.

How long does shipping typically take? +

Orders are processed within 1–2 business days, and delivery typically arrives in 7–10 business days. Tracking information is provided once your order ships so you can follow its progress every step of the way.

Please read our Shipping Policy for more information.

What if this isn't right for me? What's the return policy? +

Every TENAX product is backed by a 30-day return policy, giving the opportunity to try it and ensure it meets expectations. If it doesn’t feel like the right fit, returns are available within 30 days of delivery in accordance with the return guidelines.
