The other half
of your filter.
The upper filtration chamber — a stainless steel mesh that traps sediment and boosts ionization, paired with the Ionic Stainless Steel plate that generates negative ions and resists limescale. The annual companion to your NMC cartridge: refresh it once a year for full filtration and that soft, ionised spray.

Mesh + plate.
The ionic finish.
The upper chamber is the top half of the filter — the sediment mesh and the ionic exit plate that give your water its final polish and that soft, negatively-ionised spray.
Two twists.
Once a year.
When your yearly reminder lands, swap the upper chamber. The whole job — open, seat, close — takes about a minute. No plumber, no mess, no interruption to your day.
Everything to refresh
the top half.
The upper chamber, the ionic plate and a fresh washer — matched to your fixture. Pair it with a new NMC cartridge for a fully refreshed filter.
What buyers say
about the upper chamber set.
Verified customer reviews from buyers of the upper chamber spare set — summarised honestly by AI. The trust strip above shows totals across every platform we sell on.
Reviewers describe the swap as a one-minute job and note the spray feels finer and softer again after fitting a fresh upper chamber. Several mention doing it once a year alongside a cartridge change, and a few highlight less limescale on the plate.
The upper chamber — answered.
It's the top half of your Ionic Shower Filter — the upper filtration chamber with its stainless steel sediment mesh and the Ionic Stainless Steel spray plate. Together they trap fine sediment and give your water its ion-rich, limescale-resistant finish.
About once a year — every 10 to 12 months. Where the NMC cartridge is your roughly 2-month refill, the upper chamber is the annual refresh that keeps the mesh and ionic plate working at full strength.
Pick your fixture above: Handheld (10 cm), Handheld (12 cm), Wall Mount, or Over Head. Each set is matched to that model of the blu Ionic Shower Filter — check the diameter on your current head if you're unsure.
Under a minute, no tools. Twist the old upper chamber off the filter head, seat the new one until it clicks, hand-tighten, then run the water for 15 to 20 seconds to clear any trapped air.
Yes — they work together. The NMC cartridge does the heavy filtration (chlorine, heavy metals and bacteria) and swaps every roughly 2 months; the upper chamber adds the sediment mesh and the ionic spray plate and refreshes once a year.
As water charges through the perforations precision-etched at 0.3 mm, it generates negative ions — softening the spray, resisting limescale build-up, and helping prevent biofilm on the showerhead itself.
Yes — this is the original blu upper chamber set, engineered to spec and part of the system independently tested by TÜV, SGS and Eurofins. Buy from bludubai.com or our official stores to be sure you're getting genuine blu parts.
