Purified water undergoes advanced processes like reverse osmosis, distillation, or UV treatment, removing almost all impurities, bacteria, and chemicals. 

Filtered water removes sediments, chlorine, and some contaminants but cannot eliminate microorganisms or dissolved toxins, making purified water safer and cleaner for drinking compared to filtered water.

Let’s dive in and learn more about it.

What is Purified Water?

Purified water is water that has undergone advanced treatment processes, such as reverse osmosis, distillation, or UV purification, to remove impurities, contaminants, bacteria, viruses, and harmful chemicals, making it safe and clean for drinking.

Key Differences Between Filtered and Purified Water

Purified water undergoes advanced treatment, removing most contaminants, while filtered water only removes larger particles, sediments, and some chemicals.

The Process of Purification vs Filtration

Filtration uses a physical barrier or media to remove sediments, dirt, chlorine, and some impurities. Purification, however, involves multi-stage processes like reverse osmosis, distillation, or UV treatment, eliminating bacteria, viruses, heavy metals, chemicals, and other contaminants. Purification ensures almost all impurities are removed, producing cleaner and safer drinking water compared to basic filtration.

The Winner:

Purified water is superior due to its thorough multi-stage treatment.

Level of Impurity Removal of Purified Water vs Filtered Water

Filtered water removes visible particles, sediments, chlorine, and some chemicals but cannot eliminate microorganisms or dissolved toxins. Purified water, through advanced processes, removes nearly all impurities, including bacteria, viruses, heavy metals, and harmful chemicals, ensuring high-quality, safe, and contaminant-free drinking water.

The Winner:

Purified water removes more impurities, making it safer and cleaner.

Taste and Health Impact of Purified Water vs. Filtered Water

Filtered water improves taste by removing chlorine and sediments but may retain some harmful contaminants. Purified water provides a cleaner taste, free from chemicals and microorganisms. Drinking purified water reduces risks of waterborne diseases and ensures overall better health compared to only filtered water.

The Winner:

Purified water offers better taste and health benefits.

Cost and Availability of Purified Water vs Filtered Water

Filtered water systems are generally more affordable, widely available, and easier to maintain. Purified water systems, such as RO or UV purifiers, are more expensive, require electricity and maintenance, and may be less accessible, but they provide higher quality water. Costs vary depending on system type and brand.

The Winner:

Filtered water wins for affordability and accessibility.

Benefits of Purified Water vs Filtered Water

Filtered water provides cleaner water, improves taste, and is convenient and cost-effective. Purified water offers high-level safety, eliminates bacteria, viruses, chemicals, and heavy metals, ensures long-term health benefits, and is ideal for sensitive users or areas with poor water quality.

The Winner:

Purified water provides greater health and safety benefits.

Drawbacks of Purified Water vs Filtered Water

Purified water systems are expensive, need electricity, regular maintenance, and may remove beneficial minerals. Filtered water cannot remove all contaminants, bacteria, viruses, or heavy metals, providing only partially clean water and potentially leaving health risks if used exclusively.

The Winner:

Filtered water is easier and cheaper to maintain.

Types of Purifier

Purifiers include RO (Reverse Osmosis), UV (Ultraviolet), UF (Ultrafiltration), and gravity-based purifiers, each offering different purification levels depending on water quality and source.

Types of Filter

Filters include activated carbon, sediment, ceramic, and inline faucet filters, designed to remove physical impurities, chlorine, and odors and improve taste, but they cannot remove all microorganisms or dissolved chemicals.

Which One Should You Choose?

Choose filtered water for affordability, convenience, and basic purification. Opt for purified water if safety, contaminant removal, and long-term health are your priorities, especially in areas with unsafe water sources.

Frequently Asked Questions About What Is the Difference between Purified and Filtered Water?

Question: Is purified water always better than filtered water?

Answers: Purified water is generally safer because it removes more contaminants, bacteria, and chemicals. However, filtered water can be sufficient in areas with clean tap water, depending on quality and personal needs.

Question: Can I use filtered water for cooking and drinking?

Answers: Yes, filtered water is safe for cooking and drinking if your source water is reasonably clean. It removes sediments, chlorine, and odors, improving taste, but may not remove all bacteria or chemicals.

Question: Does purified water taste different from filtered water?

Answers: Purified water often tastes cleaner and fresher because it removes almost all impurities, including minerals and chemicals. Filtered water may retain some taste or odor depending on filtration method and water quality.

Question: Which is more affordable: purified or filtered water?

Answers: Filtered water is generally more affordable due to simpler technology and lower maintenance. Purified water systems like RO or UV are costlier, require electricity, replacement parts, and higher initial investment.

Question: Can filtered water remove bacteria and viruses?

Answers: No, most basic filters cannot remove bacteria or viruses. Only advanced purification methods like RO, UV, or distillation effectively eliminate microorganisms, ensuring safer drinking water.

Question: Is purified water safe for babies?

Answers: Yes, purified water is safe for babies, as it removes harmful contaminants, bacteria, and chemicals. Ensure the water is fresh and the purification system is properly maintained

Shift Tech BD provides Water Purifier installation and maintenance services across Bangladesh to ensure reliable performance and customer satisfaction. Some of the key areas we serve include

• Water Purifier installation and maintenance in Khulna
• Water Purifier installation and maintenance in Dhaka
• Water Purifier installation and maintenance in Chattogram

Clean drinking water is essential for good health, and choosing the right water purifier ensures safety from harmful contaminants while matching your home’s water quality, usage, and budget.

Types of Water Purifiers

Different technologies remove specific contaminants based on water type and quality.

RO (Reverse Osmosis) Water Purifier

RO purifiers use a semi-permeable membrane to remove dissolved salts, heavy metals, and impurities. Ideal for high TDS or hard water, they provide safe, great-tasting water but may also strip beneficial minerals unless paired with a mineral retention feature.

UV (Ultraviolet) Water Purifier

UV purifiers use ultraviolet light to kill bacteria, viruses, and microbes without altering the water’s taste. They’re best for low TDS water with microbial contamination and require electricity to operate effectively, making them unsuitable for high TDS or muddy water.

UF (Ultra-filtration) Water Purifier

UF purifiers use a membrane to filter out bacteria, cysts, and other microorganisms without electricity. Best for low TDS water, they work even with turbid water and keep minerals intact but are not effective against dissolved salts.

Activated Carbon Water Purifier

Activated carbon purifiers remove chlorine, pesticides, bad taste, and odor from water. They are ideal for municipal supply water with low TDS, improving taste and smell, but cannot remove dissolved salts or microorganisms alone.

Checklist Before Buying a Water Purifier

Evaluate water quality, technology, storage, budget, maintenance cost, and service availability to ensure the purifier meets your family’s needs and long-term performance expectations.

Water Quality & TDS Level

Before buying, test your water’s TDS level using a TDS meter or laboratory report. High TDS water above 500 ppm requires an RO purifier, while low TDS water under 300 ppm works best with UV or UF systems. Correctly matching the purifier to your water quality ensures optimal performance, better taste, and safe drinking water, while avoiding unnecessary expenses on unsuitable purification technologies.

Check Your Water Supply Source

Knowing your water source—municipal supply, borewell, or a mixed source—helps determine the type of contaminants present. Borewell water often contains high TDS and heavy metals, making RO systems ideal. Municipal water may have chlorine and microbial contamination, best treated with UV or activated carbon purifiers. If your water supply changes seasonally, a combination system such as RO+UV+UF ensures consistent purification performance throughout the year for safe drinking water.

Size of Your Family and Water Usage

Household size directly affects the purifier capacity needed. A small family may need a compact unit with moderate output, while a large family should choose higher purification capacity with larger storage tanks. Consider daily cooking and drinking needs as well. Underestimating capacity can lead to shortages during peak hours, while oversized systems may waste water and energy. Choosing the right size ensures efficiency, convenience, and continuous availability of purified water.

Purification Capacity & Storage

Purification capacity is measured in liters per hour (LPH), indicating how quickly the purifier can process water. Higher capacity models suit larger households and areas with high daily water needs. Storage capacity ensures you have a ready supply during power cuts or peak usage times. For small families, 7–8 liters may suffice, but larger homes may need 10–12 liters. Balancing purification speed and storage prevents shortages without overloading your kitchen space.

Electric vs Non-Electric

Electric purifiers, such as RO and UV models, require constant power to operate and are best for high TDS or contaminated water. Non-electric purifiers, like UF and activated carbon filters, work without electricity and are ideal for low TDS areas or regions with frequent power cuts. Your choice depends on water quality and electricity availability. Selecting the right type ensures uninterrupted access to safe drinking water without unnecessary dependency on electrical supply.

Water Purifier Installation Space

Before purchase, measure your available kitchen or utility area to determine whether a wall-mounted or countertop model is best. Wall-mounted purifiers save space but require proper support and plumbing, while countertop units are portable but occupy counter area. Ensure proximity to a water inlet and drainage outlet. Planning installation space avoids future fitting problems and keeps your kitchen organized, allowing the purifier to function optimally while blending with your interior layout.

At Shift Tech BD, we provide skilled technicians, quick response times, authentic replacement parts, and dependable service to keep your water purifier running efficiently. Our solutions ensure your business consistently enjoys high-quality water.

We offer professional water purifier installation and maintenance services throughout Bangladesh, guaranteeing optimal performance and complete customer satisfaction. Key areas we cover include:

• Water Purifier installation and maintenance in Dhaka
• Water Purifier installation and maintenance in Chattogram
• Water Purifier installation and maintenance in Khulna

Ease of Water Purifier Use

A water purifier should be user-friendly for all family members. Look for simple dispensing options, easy-to-read indicators, and straightforward controls. Models with quick filter access make cleaning and maintenance simpler. Automatic shut-off features prevent overflows, and transparent tanks let you monitor water levels. A design that is intuitive to operate reduces dependency on others, ensures proper usage, and increases the purifier’s lifespan by encouraging regular upkeep without technical complications or extra effort.

Filters Offered By a Water Purifier

Check the stages of filtration your purifier offers. A good system typically includes sediment, activated carbon, and post-carbon filters, with RO, UV, or UF technology depending on water quality. Multi-stage filtration removes physical, chemical, and biological impurities effectively. More advanced systems may also include mineral retention filters for healthier water. Understanding the filter types ensures you get the right protection against contaminants while maintaining the taste, odor, and nutritional quality of water.

Maintenance & Filter Replacement Cost

Maintenance is an ongoing part of owning a purifier. Check the recommended filter replacement frequency and annual maintenance contract (AMC) charges. RO membranes may last 1–2 years, but carbon and sediment filters require more frequent changes. Choosing a purifier with affordable and easily available spare parts lowers long-term costs. Ignoring maintenance can reduce performance and risk health issues, so consider total annual expenses before purchase to ensure sustainability and safe water.

Brand & Warranty Service Network

A reputed brand often guarantees better build quality, reliable purification, and longer-lasting components. Check warranty terms for both parts and labor, and ensure a strong service network exists in your area. Quick access to trained technicians helps with timely filter changes and repairs. A weak service network can cause downtime, leading to unsafe water. Selecting a trusted brand with proven service support ensures long-term performance and peace of mind for your family.

Budget & Long-Term Value

Budget should cover both initial purchase and recurring costs like filter changes, electricity, and AMC. Avoid focusing only on the lowest price; instead, weigh features, durability, and efficiency. A slightly higher investment can mean fewer breakdowns and better water quality over time. Long-term value comes from consistent performance, low maintenance issues, and good service support. Spending wisely at the start ensures years of safe, great-tasting water without constant repair headaches or extra costs.

Check User Reviews Before Final Decision

Reading verified customer reviews helps you understand real-world performance, durability, and service quality. Look for repeated complaints or consistent praise to identify strengths and weaknesses. Avoid relying solely on product descriptions or advertisements. User experiences often reveal hidden issues such as slow service, high maintenance costs, or unreliable filtration. Checking reviews ensures you choose a purifier that meets expectations in practice, not just on paper, saving you from future disappointments.

You should change your water purifier filters when you notice reduced water flow, cloudy appearance, bad taste, unusual noises, increased reject water, maintenance alerts, or after exceeding the manufacturer’s recommended usage period to ensure safe, clean, and fresh-tasting water.

Flow Rate Is Slower Than Usual

A noticeable decrease in water flow indicates filter clogging. This means impurities are blocking the filtration process, and replacing the filter will restore proper water pressure and flow.

Cloudy Or Discolored Water

If purified water appears cloudy or has a strange color, it often means the filter can no longer trap fine particles, making immediate replacement necessary to ensure water safety.

Bad Taste or Less Sweet

When water tastes bitter or metallic or simply loses its natural sweetness, the carbon filter might be saturated and unable to remove taste-altering contaminants effectively.

Unusual Noises from the Purifier

Strange humming, buzzing, or vibrating sounds from the purifier can indicate blocked filters, causing the motor or pump to work harder than normal to push water through.

More Water Gets Wasted As Reject Water

If your RO purifier produces more reject water than usual, it may mean the RO membrane or pre-filters are clogged and need prompt replacement to restore efficiency.

Maintenance Alerts from Smart Purifiers

Modern purifiers have filter change indicators or digital alerts. When these turn on, it’s a direct signal to replace the filter for continued safe and clean water.

Exceeded Recommended Usage Time

Every filter has a maximum usage lifespan. Using it beyond the recommended period can reduce efficiency and risk contamination, so replacement on schedule is necessary.

General Timeline for Changing Water Purifier Filters

Sediment filter: Every 6–12 months, depending on water quality.

Carbon filter: Replace every 6–12 months for best taste and odor removal.

RO membrane: Lasts 2–3 years with proper pre-filter maintenance.

UV lamp: Change yearly to maintain germicidal effectiveness.

You can maintain the filters by following the above guidelines. However, if you ever need any help, Shift Tech BD provides water purifier service and maintenance in Dhaka with their experienced team.

To maintain commercial water purifiers, regularly replace filters, clean storage tanks, check for leaks, and inspect electrical components. Use the purifier daily, monitor water quality, and schedule professional servicing to ensure safe, fresh-tasting water and long-lasting system performance for your business. Let’s talk about it in detail.

Maintenance Practices Businesses Should Follow

Perform regular filter changes, clean water tanks, monitor system performance, and schedule professional servicing to ensure optimal water quality and purifier longevity.

1. Use the Purifier Regularly

Running the purifier daily helps keep water flowing, prevents bacterial buildup, and maintains filter efficiency. Inactivity can cause stagnant water, unpleasant odors, and reduced filtration performance. Consistent use ensures the system stays in good working condition.

2. Timely Filter Replacement

Replace filters as per manufacturer guidelines to maintain water purity and taste. Overused filters can cause contamination and strain the purifier. A timely change improves efficiency and prolongs the system’s lifespan.

3. Regular Tank Cleaning and Sanitization

Clean and sanitize the storage tank every few months to prevent bacterial growth and mineral deposits. A clean tank ensures safe, fresh-tasting water and maintains the system’s hygiene standards.

4. Leak and Pressure Monitoring

Regularly check for leaks, pressure drops, or unusual surges in the system. Identifying these issues early prevents damage, reduces repair costs, and ensures smooth water flow in daily operations.

5. Electrical Component Checks

Inspect wiring, switches, and electrical connections to ensure safe operation. Faulty electrical parts can cause system failure or hazards, so timely repairs help maintain reliable purifier performance.

6. Check and Clean the External Parts

Wipe the purifier’s exterior to remove dust and grime, preventing contamination from reaching internal components. Keeping the outside clean also improves hygiene and the unit’s professional appearance.

What to Check During Routine Inspections

Flow Rate Is Slower Than Usual: Indicates clogged filters or internal blockages. Immediate cleaning or filter replacement is needed to restore normal water flow.

Cloudy Or Discolored Water: May signal sediment buildup, worn filters, or contamination in the tank. Inspect and clean components promptly.

Bad Taste Or Less Sweet: Suggests filter saturation, bacterial growth, or chemical imbalance. Replace filters and sanitize the tank.

Unusual Noises from the Purifier: Can be caused by trapped air, loose components, or pump issues. Investigate to prevent system damage.

Maintenance Alerts from Smart Purifiers: Smart models display alerts for filter changes, cleaning, or system errors. Address them promptly for uninterrupted operation.

Exceeded Recommended Usage Time: Running beyond rated capacity strains filters and internal parts. Replace or service components to prevent failures.

Common Issues and Troubleshooting for Commercial Water Purifiers

Frequent problems include slow flow, unusual taste, cloudy water, or leaks. Most can be resolved by cleaning the tank, replacing filters, checking water pressure, and inspecting electrical connections. Persistent issues should be addressed by a trained technician to avoid costly damage.

Why Is Scheduling Professional Servicing necessary?
