Which Water Purifier Is Best for Low Water Pressure Homes?
If you have low water pressure at home, you need a pump-assisted RO purifier. That’s it. Simple. Now let me explain why, and why our CleanTech RO systems are built exactly for this problem.
My Name is Md. Monirul Islam, and I Fix Water Problems Every Day
I’m the service manager at CleanTech Engineering LTD. For 15 years, I’ve visited homes in Dhaka, Chittagong, Sylhet, Rajshahi, everywhere. And I hear the same complaint: “Sir, our water pressure is very low. Will an RO purifier work?”
Yes, it will. If it has a booster pump. Let me tell you exactly what works, what doesn’t, and how to choose the right one for your home.
What is Low Water Pressure and Why Should You Care?
Low water pressure means your tap water flows like a thin stream instead of a strong flow.
In Bangladesh, most homes have water pressure between 20-35 PSI (PSI = pounds per square inch). But a normal RO purifier needs at least 40 PSI to work. If pressure is lower, the RO stops purifying — or works so slowly that you get only 2-3 glasses per hour.
That’s why you need a booster pump. It’s like a small heart that pushes water into the RO system with enough force.
Three Types of Purifiers for Low-Pressure Homes
1. Pump-Assisted RO Purifiers (The BEST Choice for 90% of Bangladeshi Homes)
This is what we install in almost every home with low pressure.
- How it works: A small built-in pump increases your water pressure from 20 PSI to 55-60 PSI automatically. The RO membrane then removes all dissolved salts, arsenic, lead, bacteria — everything.
- Why it’s perfect for Bangladesh:
- Built-in Booster Pump: Works even if your pressure is only 20 PSI. No extra equipment needed.
- Removes TDS, Arsenic, Lead: Essential for borewell and tubewell water (most common in Bangladesh).
- Fast Flow Rate: Get 1 liter per minute — no waiting.
- Large Storage Tank: 12-20 liters ready anytime, even during load-shedding.
Our CleanTech Models That Solve This:
- CleanTech PowerRO 12L — ৳18,999 (Works at just 20 PSI, 8-stage purification).
- CleanTech Zero-Waste RO 20L — ৳24,999 (Saves 90% water, booster pump + smart TDS controller).
Note: Every CleanTech RO includes the booster pump at NO extra cost. Other brands charge ৳3,000-5,000 extra for the pump.
2. Gravity-Based Purifiers (Only for City Water with Very Low TDS)
Use this ONLY if:
- Your TDS is below 200 ppm (very rare in Bangladesh).
- You have NO electricity.
- You use Dhaka WASA water that’s already soft.
How it works: You pour water in the top, gravity pulls it down through filters. No pump needed.
Our Model: CleanTech Gravity Pure — ৳5,999
Warning: This will NOT remove dissolved salts, arsenic, or fluoride. If your water is salty or you use a tubewell, this is NOT safe.
3. Filter Pitchers (For Renters or Small Families)
Best for: Students, renters, or families of 2-3 people with municipal water.
Our Model: CleanTech SafePitcher — ৳1,499
Limitation: Cannot handle high TDS. Must change the filter every 2 months.
How to Choose the Right Purifier in 3 Simple Steps
Step 1: Test Your Water (We Do This FREE)
- Check Pressure: We’ll measure your PSI. If it’s below 40 PSI → you need our pump-assisted RO.
- Check TDS: If TDS is above 300 ppm → you MUST have RO. Most Bangladeshi borewell water is 800-1500 ppm.
Step 2: Match Your Water Source
| Your Water Source | What You Need |
| Borewell / Tubewell | CleanTech PowerRO (pump-assisted) |
| Tanker Water | CleanTech PowerRO |
| Dhaka WASA Tap | RO if TDS >300, or Gravity if TDS <200 |
| Frequent Load-shedding | Any CleanTech RO (works with home inverter) |
Step 3: Choose Size for Your Family
- 2-4 people → 12 liter tank
- 5-8 people → 20 liter tank

Real Customer Story
“We live in Uttara, Dhaka. Our water pressure was only 22 PSI. We bought a normal RO first — it barely gave 2 glasses per hour. CleanTech came, tested our water, and installed their PowerRO. Now we get 12 liters in 30 minutes. The booster pump is silent and works perfectly.”
— Mrs. Akter, Uttara
Frequently Asked Questions
Q: What is the minimum water pressure for RO purifiers?
A: Normal RO needs 40 PSI. Our CleanTech RO works at just 20 PSI because of the booster pump.
Q: Can I use a gravity filter for borewell water?
A: No. Gravity filters cannot remove the salt and arsenic in borewell water. Only RO can.
Q: How much electricity does the booster pump use?
A: Very little — about 5 watts. That’s less than ৳15 per month.
Q: What is the best water purifier price in Bangladesh for low pressure?
A: CleanTech PowerRO 12L at ৳18,999 is the best value. Includes free installation and booster pump.
Q: Do Walton or RFL water purifiers work for low pressure?
A: Most Walton/RFL models don’t have booster pumps. They can’t handle low pressure or high TDS properly.
Final Answer: Which One Should You Buy?
If you have low water pressure (below 40 PSI) in Bangladesh, buy a pump-assisted RO purifier. Period.
- Gravity filters and pitchers cannot handle high TDS water.
- Only RO removes arsenic, lead, and dissolved salts.
- CleanTech’s built-in booster pump solves the pressure problem at no extra cost.
