Choosing the right water filter can be overwhelming with so many options on the market. To help you decide, let’s break down the differences between popular types: Brita filters, water distillers, reverse osmosis systems, and other filtration options, considering cost, advantages, disadvantages, ease of use, ease of cleaning, and water quality.
1. Brita Filters (Activated Carbon)
Rough Price: £15–£30 for a pitcher; £5–£10 for replacement filters (last ~1 month).
Advantages: Affordable, widely available, reduces chlorine, odour, and some contaminants. Compact and portable.
Disadvantages: Limited filtration—doesn’t remove heavy metals, fluoride, or bacteria. Needs frequent filter replacement.
Ease of Use: Simple—just fill and pour.
Ease of Cleaning: Rinse the pitcher and replace filters as needed.
Water Quality: Moderate improvement, suitable for everyday use but not comprehensive.
2. Water Distillers
Rough Price: £80–£300 for a home distiller.
Advantages: Removes nearly all impurities, including bacteria, heavy metals, and minerals. Produces ultra-pure water.
Disadvantages: Time-consuming (4–6 hours per gallon), removes beneficial minerals, high energy usage, and bulky.
Ease of Use: Plug in, fill with water, and wait for the distillation process.
Ease of Cleaning: Requires regular descaling to remove residue from boiled-off minerals.
Water Quality: Extremely pure but may taste flat without minerals.
3. Reverse Osmosis (RO) Systems
Rough Price: £200–£500 for under-sink and counter top systems; £30–£100 for annual filter replacements.
Advantages: Removes 99% of contaminants, including heavy metals, fluoride, and nitrates. Often includes a remineralisation stage for taste.
Disadvantages: Produces several litres of waste water per litre filtered. Initial cost and installation can be high.
Ease of Use: Once installed, it’s effortless—just turn on the tap if using under sink. Counter top will require filling each time.
Ease of Cleaning: Filter changes (2–3 times a year) . If counter top then wash filter jugs x 2 once a week.
Water Quality: Exceptional—ideal for drinking and cooking.
4. Other Filters
Ceramic Filters:
Price: £40–£120.
Advantages: Removes bacteria and some heavy metals, durable.
Disadvantages: Slow flow rate, doesn’t filter fluoride.
Ease of Use & Cleaning: Easy to maintain with regular scrubbing.
Water Quality: Good for reducing pathogens but not comprehensive.
UV Purifiers:
Price: £100–£300.
Advantages: Destroys bacteria and viruses instantly.
Disadvantages: Doesn’t remove heavy metals or chemicals. Needs electricity.
Ease of Use & Cleaning: Low-maintenance. Replace bulbs annually.
Water Quality: Excellent for biological contamination but requires additional filtration for chemicals.
Alkaline Filters:
Price: £100–£400.
Advantages: Adds minerals like calcium and magnesium, improves taste.
Disadvantages: Focuses on pH rather than contaminant removal.
Ease of Use & Cleaning: Similar to Brita systems.
Water Quality: Enhanced taste and pH but limited filtration.
Which One Should You Choose?
For Everyday Convenience: A Brita filter is affordable and easy but limited in scope and water quality.
For the Purest Water: Go for a distiller or reverse osmosis system. RO is more efficient; distillers are better for occasional use.
For Camping or Off-Grid Living: Consider a ceramic filter or portable UV purifier.
For Taste Improvement: An alkaline filter or RO system with remineralisation adds a polished finish to your water.
Final Thoughts
Your choice depends on your budget, water quality needs, and lifestyle. If you’re unsure, start simple with a Brita and upgrade to a reverse osmosis system if your tap water has serious contaminants.
