Water Filter Maintenance & Replacement:
Hampshire Hard Water Guide
Your filters are working overtime in Hampshire's extreme hard water areas. Here's the truth about replacement schedules that manufacturers don't tell you.





Why Hampshire Hard Water Kills Your Filters Faster
Water companies publish water hardness data, but they don't explain what it means for your filters. In Andover (SP10/SP11), Marlborough (SN8), and Hungerford (RG17), water hardness regularly exceeds 300mg/L calcium carbonate - classified as "very hard" water.
The Hidden Filter Killer
Hard water doesn't just contain calcium. It carries microscopic sediment, mineral deposits, and dissolved solite that quickly clog filter media. A filter rated for 6 months in soft water areas (like Scotland or Wales) may last only 3-4 months in Hampshire.
Replacement Schedule by Filter Type
These schedules are adjusted for Hampshire's hard water. Standard manufacturer recommendations assume average UK water hardness - we're well above average.

Carbon Inline Filters
Water2, Waterdrop, Budget brands
Most affected by hard water sediment. Monitor flow rate closely.

Under-Sink Reverse Osmosis
Osmio, APEC, iSpring
Pre-filters clog faster; RO membrane protected but still affected.

Whole House Systems
Aquasana, Pelican, 3M
Higher capacity but entire house load accelerates wear.

Refrigerator Filters
Samsung, LG, Beko
Often forgotten! Scale buildup reduces ice quality too.

Jug/Pitcher Filters
Brita, PUR, ZeroWater
Cheapest per filter but most frequent replacement.
6 Warning Signs Your Filter Needs Replacing
Don't wait for the scheduled date. Your filter may need replacing sooner. Watch for these signs.



Reduced Water Flow
Water pressure from filtered tap noticeably slower than before. Flow rate decreased by 30% or more.
Strange Taste Returns
Chlorine taste, metallic flavour, or earthy smell coming back despite filter installed.
Visible Sediment
Particles visible in water, cloudiness, or white specks (calcium) appearing.
Filter Housing Discoloration
Clear housing turning brown, orange, or showing sediment buildup inside.
Time Since Last Change
More than 4 months since last replacement in Hampshire hard water areas.
Ice Tastes Different
Refrigerator ice cubes have off flavour or appear cloudy.
Monthly Maintenance Checklist
Spend 10 minutes each month to prevent costly problems. This simple routine helps you catch issues early and ensures your filter is actually working.

Pro Tip: Keep a Maintenance Log
Write the installation date on the filter housing with a permanent marker. Keep a simple log in your phone calendar with reminders for:
- • Monthly check reminder (first of each month)
- • Replacement reminder (set 2 weeks before due date)
- • Annual professional inspection

5 Ways to Reduce Your Filter Costs


Buy in Bulk
Most filter brands offer 3-packs or 6-packs at 20-30% savings. Calculate your annual need and buy ahead.
Subscribe & Save
Amazon, Water2, and others offer 10-15% off subscriptions. Set delivery for your Hampshire replacement schedule.
Quality Over Cheap
Premium filters last longer even in hard water. A £30 filter lasting 4 months beats a £15 filter lasting 2 months.
Add Pre-Filtration
A sediment pre-filter (£30/year) can double the life of your main filter by catching larger particles first.
Consider Aquabion
Aquabion water conditioning reduces sediment load on filters. Many customers report 20-30% longer filter life.
Annual Service Plan
Professional annual service often includes discounted filters. Ask about maintenance packages.
