Whole House vs. Pitcher Filter
Mam Nature Swiss vs. Brita
Brita is the most widely recognised water filter brand in Europe. But a pitcher filter and a whole-house filtration system are fundamentally different technologies — one filters the glass you fill, the other filters every litre that enters your home. This comparison explains what each can and cannot do.
The fundamental difference: coverage
Brita filters the water in one jug or at one tap. Mam Nature filters all water entering your home — including shower, bathing, cooking, and drinking water — at the main supply line. PFAS and chlorine enter the body through skin and steam, not only through drinking. A pitcher filter addresses one route; a whole-house filter addresses all of them.
Not a substitute for whole-house filtration.
Side-by-Side Comparison
| Criterion | Mam Nature Swiss | Brita (Pitcher / On-Tap) |
|---|---|---|
| Coverage | ✓ Whole house (all taps + shower) Point-of-entry installation at the main supply line. Filters every litre entering the home — drinking water, cooking water, and bathing water. | – Single tap / pitcher only Pitcher filters treat one container at a time. Even Brita on-tap filters treat one cold-water tap. Shower and bathing water are unfiltered. |
| PFAS removal | ✓ 95–99.9% (ETH Zurich) Independently certified by ETH Zurich (ISO/IEC 17025) for the full PFAS spectrum, including short-chain PFAS (PFBS, PFHxA) that activated carbon struggles with. | – Limited / uncertified Brita's standard activated carbon reduces some PFAS at low concentrations, but has no published independent certification for full-spectrum PFAS removal. Short-chain PFAS are largely unaffected by carbon filtration. |
| Heavy metal removal | ✓ 95–99% (ETH Zurich) Lead, copper, arsenic, cadmium, chromium, aluminium — tested and certified at ETH Zurich. | – Partial (lead, copper only) Brita Maxtra+ reduces lead and copper. Arsenic, chromium, and cadmium are not listed as certified reductions for standard Brita filters. |
| Microplastics removal | ✓ Yes — down to 0.1 µm The physical membrane pre-stage removes microplastics and particles larger than 0.1 µm before the adsorption stage. | – Not certified Standard Brita pitchers and taps do not have published independent certifications for microplastic removal. |
| Mineral retention | ✓ Full retention Selective adsorption targets contaminants. Calcium, magnesium, and potassium pass through at natural concentrations — WHO-recommended mineral intake maintained. | – Partial reduction Brita Maxtra+ uses an ion-exchange resin that partially reduces calcium and magnesium (reducing water hardness). This lowers mineral intake compared to unfiltered water. |
| Flow rate | ✓ Up to 2,000 L/hr No restriction on household flow. All appliances, showers, and taps operate at full pressure. | – ~0.5–2 L/min Pitcher filters: ~0.5 L/min gravity flow. On-tap Brita units: 1–2 L/min maximum. Cannot supply bathing, laundry, or dishwasher water. |
| Bathing water protection | ✓ Yes — all water in the home PFAS and chlorine are absorbed through skin and inhaled in steam. Point-of-entry filtration protects against this exposure pathway. | – None Pitcher and on-tap filters only treat drinking water. Shower water — a significant route of chlorine and microplastic exposure — is not covered. |
| Cartridge lifespan | ✓ 150 m³ (~1 year) One cartridge per year for a typical Swiss household of 2–4 people. Replacement takes approximately 10 minutes. | – 150 L per cartridge (~4–8 weeks) Brita Maxtra+ recommends replacement every 4 weeks or 150 litres for typical use. A household of 4 uses approximately 8–14 cartridges per year for drinking water alone. |
| 10-year cost (EUR, estimate) | = ~€3,600–€4,600 total Complete Set purchase (€2,998) + ~€240/yr cartridge. Zero wastewater. No salt or chemical costs. Covers the entire household. | = ~€500–€700 for drinking only Pitcher or on-tap unit (~€30–€80) + ~€45–€100/yr cartridges (drinking water only). Add-on cost if separate shower or bathing filtration is also desired. |
| Cost per litre (filtered) | ✓ ~€0.002–0.004/L Calculated over 10 years across full household water usage (~200–250 m³/yr). Significantly lower than bottled water. | – ~€0.03–0.06/L Calculated for drinking water only at ~150–200 L/month per person and typical cartridge cost. Higher per-litre cost due to short cartridge lifespan. |
| Installation | – 1–2 hours (plumber, one-time) Inline installation at the main supply — a standard plumbing job requiring no specialist knowledge. No ongoing professional maintenance. | ✓ No installation required Pitcher filters require no installation. Brita on-tap models attach in minutes. |
| Certifications | ✓ ETH Zurich ISO/IEC 17025 · Swiss Safety Center · ISO 13485 Third-party independent testing at Swiss Federal Institute of Technology. Performance data publicly available. | – NSF/ANSI 42 & 53 (in some markets) Some Brita products carry NSF/ANSI 42 (aesthetics) and 53 (health effects, lead) certifications in the US market. No independent PFAS certification for EU/CH market products. |
| Country of manufacture | = Switzerland 316L medical-grade stainless steel housing. Swiss Made under Swissness Ordinance. | = Germany Brita is a German brand (Taunusstein). Plastics-intensive product construction. |
Common Questions
Is a Brita filter enough to remove PFAS?
Standard Brita activated carbon filters can reduce some longer-chain PFAS at low concentrations, but Brita does not publish independent third-party certification data for full-spectrum PFAS removal. Short-chain PFAS (PFBS, PFHxA, PFBA), which are the compounds now increasingly found in European tap water as legacy long-chain PFAS are phased out, are largely unaffected by activated carbon filtration. Certified selective adsorption technology — like the Mam Nature Swiss Fine Filter — achieves 95–99.9% removal across the full PFAS spectrum, as independently verified by ETH Zurich.
Does a pitcher filter protect my family from PFAS in shower water?
No. Pitcher filters and on-tap filters only treat drinking water. PFAS, chlorine, and other volatile contaminants are absorbed through the skin and inhaled as steam during showering. Research published in the American Journal of Public Health (Brown, Bishop & Rowan, 1984) found that dermal absorption and inhalation during showering can account for a significant portion of total chlorine and volatile chemical exposure in households with unfiltered water. Whole-house filtration — which treats all water entering the home at the supply line — is the only approach that addresses all exposure routes.
How does the Mam Nature filter compare to Brita in terms of running cost?
For drinking water only, Brita is cheaper upfront. The initial cost is lower (€30–€80 for a pitcher vs. €2,998 for the Mam Nature Complete Set), but Brita cartridges need replacement every 4–8 weeks at €5–€8 each, adding €45–€100 per year. Mam Nature requires one cartridge per year (€240), but covers the entire household's water — drinking, cooking, showering, bathing, and laundry. On a per-litre basis across the full home water supply, Mam Nature works out at approximately €0.002–0.004 per litre compared to €0.03–0.06 for Brita on drinking water alone.
Can I use both Brita and Mam Nature?
There is no technical obstacle, but it would be redundant. If you install a Mam Nature Fine Filter at the point-of-entry, all water — including the water going into a Brita pitcher — is already filtered. The additional Brita cartridge would provide no further benefit and would be an unnecessary ongoing cost.
Which is best for a household in Switzerland or Germany?
Swiss and German tap water is generally high quality, but PFAS contamination has been detected in multiple catchment areas, particularly near industrial zones and airports. For households in affected areas — or who simply want certified protection across all water uses — a whole-house point-of-entry system like Mam Nature Swiss provides measurably stronger and broader protection. For households in reliably clean supply areas who only want to improve taste for drinking water, a carbon pitcher filter is a lower-cost option that addresses aesthetic concerns.
