According to foreign media reports, water filtration service providers in Singapore point out that even with a good filtering system, improper use can reduce effectiveness, affect water taste, and unnecessarily increase expenses. This article guides you through 10 things to know before deciding to buy a water filter to help extend equipment lifespan and make the right installation decision.
10 Things to Know Before Buying a Water Filter - Risk of Reduced Performance and Increased Costs
1. Not Changing Filter Cartridges on Schedule
Neglecting to change filter cartridges on time is a common mistake. When used beyond the recommended period, filtering efficiency decreases and bacteria and mold can accumulate, affecting water taste.
Advice: Check manufacturer guidelines and set reminders for cartridge replacement.
2. Not Checking Tap Water Quality
Water quality varies by location, including hardness, chlorine, heavy metals, and other contaminants. Choosing an inappropriate filter may not effectively remove these pollutants.
Advice: Analyze water quality before selecting a filter.
3. Overusing the Filter System
Using the system beyond its designed capacity or duration can reduce efficiency and increase system wear.
Advice: Choose equipment appropriate for your household size and monitor usage volume.
4. Not Cleaning the Filter System
Beyond the filter cartridge itself, other components like water tanks and faucets can accumulate dirt. If not cleaned, water may develop odor or quality issues.
Advice: Clean according to manual instructions using warm water and mild soap; avoid harsh chemicals.
5. Choosing the Wrong Filter Type for Your Needs
Different filter types have different capabilities, such as:
- Carbon filters suit chlorine and odor removal
- RO systems remove various contaminants but reduce minerals
- Ceramic filters work for bacteria but don't handle chemicals
Advice: Choose based on your specific water problems or use a multi-stage system.
6. Not Flushing Before First Use
New filter cartridges may contain manufacturing dust or residue. Skipping the flush can cause cloudy or odorous water.
Advice: Run water as per instructions before initial use.
7. Ignoring Environmental Factors
Placing the filter in hot areas or direct sunlight can accelerate material degradation and increase microbial growth risk.
Advice: Install in appropriate locations away from heat and direct sunlight.
8. Overlooking Other Water Sources in Your Home
Many households filter only drinking water but neglect other sources like bathrooms, washing machines, or water heaters that may not be filtered.
Advice: Assess total water usage and install additional filtration systems if needed.
9. Not Paying Attention to Water Smell and Taste
Changes in smell or taste may signal problems like expired cartridges, system contamination, or pipe issues.
Advice: Notice abnormalities and address them immediately.
10. Ignoring Long-Term Costs
Expenses include not just the initial purchase but also cartridge replacement, maintenance, and electricity.
Advice: Consider total long-term costs, not just the initial price.
Using a water filter system helps ensure clean and safe drinking water, but small oversights like failing to change cartridges on time or choosing the wrong filter can lead to problems.
