Multi-Stage Comprehensive Filtration vs Single-Purpose Basic Filters
Basic filters address one problem at a time. pH Prescription systems provide comprehensive, layered protection.
Basic filters target one specific contaminant or problem - usually chlorine or sediment.
Reality: You may feel like you're filtering, but 95% of tap water contaminants pass right through.
We use six distinct filtration stages, each targeting different contaminant categories.
Result: Up to 99% reduction of contaminants across 15+ categories in a single system.
The dirty truth about single-stage filters and pitcher filters
Basic filters are designed for taste and odor - not safety. Here's what they don't remove:
When you use basic filters, you believe you're drinking safer water - but you're not.
A false sense of security is dangerous.
Our six-stage system doesn't just remove chlorine - we remove:
Plus we add back beneficial minerals and create alkaline, hydrogen-rich water.
What each filtration type removes - side by side
| Contaminant/Feature | pH Prescription (Multi-Stage) |
Pitcher Filters | Faucet Filters | Basic Under-Sink |
|---|---|---|---|---|
| Chlorine | 99.9% | 80-90% | 70-85% | 85-95% |
| Lead | 99.99% | 0% (No removal) | 0-30% | 30-50% |
| Mercury | 95%+ | 0% (No removal) | 0-20% | 20-40% |
| Fluoride | 95%+ | 0% (No removal) | 0% (No removal) | 10-30% at best |
| PFAS ("Forever Chemicals") | 98%+ | 0% (No removal) | 0% (No removal) | 0-20% |
| Pesticides/Herbicides | 98%+ | 50-70% | 40-60% | 60-80% |
| Pharmaceuticals | 90%+ | 0% (No removal) | 0% (No removal) | 20-40% |
| Microplastics | 99%+ | 50-60% | 40-50% | 60-75% |
| Uranium/Radium | 85-90% | 0% (No removal) | 0% (No removal) | 0-10% |
| Bacterial Contaminants | 99.9%+ | 20-40% | 30-50% | 50-70% |
| Alkaline pH Creation | Natural mineral-based | None | None | None |
| Molecular Hydrogen | Naturally generated | None | None | None |
| Water Restructuring | Yes - reduced cluster size | No | No | No |
Understanding the differences in filtration approaches
A simple carbon cartridge sits in a pitcher. Water slowly passes through, and gravity does the work.
Screws onto your kitchen faucet. Water passes through a single carbon stage as you pour.
Installed under the sink. Water is pressurized through one or two filter stages, usually carbon and sediment.
Four distinct stages work together. Water passes through KDF-55, specialized carbon, gemstone media, and mineral cartridges in sequence.
Cost of ownership and effectiveness over time
| Factor | pH Prescription | Pitcher Filters | Faucet Filters | Basic Under-Sink |
|---|---|---|---|---|
| Initial System Cost | Contact for quote (systems for every budget) |
Low upfront cost | Low upfront cost | Moderate upfront cost |
| Filter Replacement (Annual) | Affordable maintenance (professional service available) |
Frequent replacements (cartridge every 2-3 months) |
Regular replacements (cartridge every 3-4 months) |
Periodic replacements (2-4 cartridges per year) |
| Lifespan of System | 10-20+ years | Indefinite (pitcher) Cartridges every 2-3 months |
Indefinite (faucet) Cartridges every 3-4 months |
5-10 years before replacement |
| 10-Year Total Value | Best long-term value (investment pays for itself) |
Ongoing expense (adds up over time) |
Ongoing expense (limited protection) |
Moderate ongoing costs (still misses key contaminants) |
| Cost per Gallon | Pennies per gallon | Higher per gallon | Moderate per gallon | Lower than pitchers |
| Contamination Coverage | Up to 99% across 15+ categories |
Chlorine & taste only 5% coverage |
Chlorine & sediment 10% coverage |
Chlorine, sediment, some metals 30-40% coverage |
| Coverage Area | Whole home or point-of-use |
Drinking water only (limited to pitcher use) |
One faucet only | One faucet only |
| Maintenance Required | Replace cartridges every 6-18 months |
Replace cartridge every 2-3 months |
Replace cartridge every 3-4 months |
Replace cartridges every 6-12 months |
| Health Protection Value | Comprehensive protection from all major contaminants |
False sense of security misses dangerous contaminants |
False sense of security minimal protection |
Partial protection still misses PFAS, fluoride, pharma |
While pitcher and faucet filters have lower upfront costs, when you factor in:
pH Prescription systems deliver superior value: comprehensive protection at a lower cost per gallon, with replacements needed only every 6-18 months, protecting your entire home or providing whole-system drinking water.
Stop settling for false security. Get truly comprehensive water protection.
Every day you drink water with fluoride, lead, PFAS, and pharmaceuticals, these contaminants accumulate in your body.
Plus: Our professional maintenance service means our technicians handle all filter replacements for you.
Our water experts will assess your specific needs and recommend the perfect system for you.
