S7 Pro Reverse Osmosis Under-Sink Water Filter is made for people who want genuinely clean drinking water at home, without waiting for a tank to refill or dealing with bulky under-sink setups.
If you’re not fully comfortable with what’s coming out of your tap (taste, smell, or just what might be in it), this is the kind of system people upgrade to when basic jugs and faucet filters stop feeling like enough.
Is this the right filter for me?
It’s a great fit if you recognise yourself in any of these:
Who it’s not for
This might not be the best match if:
Is installation something to worry about?
Usually, no.
Bottom line: if you want cleaner water, fast flow, a compact under-sink setup, and low ongoing hassle, you’re in the right place.
Does this system remove harmful contaminants?
Yes. The S7 Pro uses a 5-stage reverse osmosis system with a 0.0001-micron RO membrane. It reduces chlorine, rust, sediment, bacteria, and over 1000 contaminants commonly found in municipal tap water.
Is the water flow slow like other RO systems?
No. This is a high-flow, tankless system rated at 400 GPD (gallons per day) with a real-time flow of about 1.6 L/min. You get clean water on demand, without waiting for a tank to refill.
Do I need a storage tank?
No. The system is fully tankless. This saves space under the sink and avoids water sitting in a storage tank.
How often do I need to change the filters?
The pre-filter typically lasts 9–12 months, while the RO membrane lasts around 18–24 months depending on your water quality and usage. Replacement filters can be ordered directly from our website as single or double packs at a fair price. Filters are tool-free and very easy to replace, taking just a few seconds.
Is it difficult to install?
Most users install it themselves by following the manual. The tankless design keeps installation simple and it’s usually done in under 30 minutes. If you prefer, any plumber can install it quickly.
Do I need special water pressure?
No. It’s designed for standard municipal water pressure and works within a wide pressure range, so additional regulators are usually not needed.
Does it waste a lot of water?
Compared to traditional RO systems, no. It operates at a 1.5:1 drain ratio, which is significantly more efficient than older systems that waste much more water.
Does it come with a tap?
Yes. It includes a dedicated tap, allowing you to easily switch between filtered drinking water and regular tap water.
Is it noisy?
The system uses an electric pump, but noise levels are low and generally not noticeable during normal kitchen use.
Is it suitable for families or shared homes?
Yes. With its high daily output and fast flow, it’s well suited for families, shared homes, and even small hospitality settings.
What warranty do I get?
The system comes with a 3-year warranty and dedicated customer support for peace of mind.

What Exactly Is in Your Local Tap Water?
Many UK households face tap water filled with hidden contaminants invisible to the eye: chlorine, heavy metals, PFAS (forever chemicals), fluoride, microplastics, limescale, and even bacteria. These not only affect taste and damage appliances over time but, more importantly, raise concerns about long-term health of you and your loved ones.
At Veltra, we design our products to protect your home from those contaminants, delivering cleaner, safer, and better-tasting water.
Common frustrations we help eliminate:
The 5-stage, 0.0001 μm RO filtration reduces a wide range of common tap-water contaminants, while the tankless design prevents water stagnation and frees up valuable space under your sink.
