Whole House vs. Refillable Carafe
Mam Nature Swiss vs. everdrop
everdrop is a Munich-based sustainability brand offering a refillable glass carafe water filter, positioned as an eco-friendly alternative to disposable pitcher systems. Mam Nature Swiss is a whole-house point-of-entry filter for PFAS, heavy metals, and chemical contaminants. These products solve very different problems — this comparison clarifies who each is actually for.
Two different goals: sustainability vs. certified contaminant removal
everdrop's strength is sustainability — refillable glass carafe, recycled plastic cartridges, B Corp certified, far less waste than disposable pitcher systems. Mam Nature's strength is independently certified contaminant removal across the whole house — PFAS, heavy metals, and chemical contaminants at every tap and shower. A carafe filters one glass at a time; a whole-house system protects every litre that enters your home.
Strong sustainability angle but not designed for full-spectrum contaminant removal.
Side-by-Side Comparison
| Criterion | Mam Nature Swiss | everdrop (Refillable Carafe) |
|---|---|---|
| Coverage | ✓ Whole house (all taps + shower) Point-of-entry installation. Every litre entering the home is filtered — drinking, cooking, bathing, laundry. | – One carafe at a time (drinking only) Manually-filled glass carafe. Only the water poured into the carafe is filtered. All other water in the home remains untreated. |
| PFAS removal | ✓ Up to 99.98% (ETH Zurich University) Independently tested at ETH Zurich (Dr. S. Bolisetty, October 2025) using EPA Method 537M for the full PFAS spectrum, including short-chain variants (PFBS, PFHxA). | – Not certified everdrop's activated carbon cartridge is designed for chlorine, taste, and lime reduction. No published independent third-party certification for PFAS removal, particularly short-chain PFAS. |
| Heavy metal removal | ✓ Up to 99.98% (ETH Zurich University) Lead, copper, arsenic, cadmium, chromium, aluminium — independently certified. | – Partial (lead, copper) Activated carbon reduces some heavy metals at low concentrations. Arsenic, cadmium and chromium not listed among certified reductions. |
| BPA removal | ✓ 97.87% (ETH Zurich University) ETH Zurich University certified BPA removal across the full filter assembly. | – Not certified No published independent certification for BPA removal. |
| Mineral retention | ✓ Full retention Selective protein-fibre adsorption targets contaminants. Calcium, magnesium and potassium pass through at natural levels. | – Partial reduction (lime) The cartridge is partly designed to reduce limescale-forming calcium, which also lowers dietary mineral intake compared to unfiltered tap water. |
| Bathing water protection | ✓ Yes — all water in the home PFAS and chlorine are absorbed through skin and inhaled in steam. Whole-house filtration addresses both exposure routes. | – None Carafe filtration only treats drinking water. Shower, bath, and bathing-water exposure routes remain uncovered. |
| Sustainability — packaging | – Long-life stainless housing + minimal packaging 316L stainless steel housing built for decades. Single annual cartridge shipped flat-packed in cardboard. Long replacement cycle reduces shipping carbon footprint. | ✓ Refillable carafe + recycled-plastic cartridges B Corp certified. Climate Neutral. Glass carafe + cartridges shipped in recyclable/recycled materials. Avoids disposable pitcher housings. |
| Sustainability — waste over 10 years | ✓ ~10 cartridges + 1 housing (multi-decade) Whole-house cartridge changed once per year. 316L housing has multi-decade lifespan; warranty 10 years, expected life 25+. | – ~120 cartridges + 1 carafe (10 years) Monthly cartridge change (~12/year × 10 years). Lower per-cartridge weight than disposable pitcher systems, but higher overall cartridge throughput than annual whole-house filtration. |
| Cartridge lifespan | ✓ ~1 year / 150,000 L Single cartridge replacement annually. 10-minute swap, no tools. | – ~1 month / 150 L Cartridge replaced approximately every 30 days or 150 L. A household consuming ~3 L/day reaches the replacement threshold in about 50 days. |
| 10-year cost (EUR, estimate) | = ~€3,600–€4,600 total (whole house) Complete Set purchase (€2,998) + ~€240/yr cartridge. Covers entire household. | = ~€1,200–€1,500 total (drinking only) Starter set ~€60–€100 + ~€10–€12/month cartridges over 10 years. Drinking water only — does not include shower, bath, or appliance water. |
| Cost per litre (filtered) | ✓ ~€0.002–0.004/L Calculated over 10 years across full household water usage. | – ~€0.08–0.10/L Calculated for drinking water at ~3 L/day per person. Higher per-litre cost due to short cartridge life and smaller throughput per unit. |
| Installation | – 1–2 hours (plumber, one-time) Professional inline installation at the main supply. | ✓ No installation required Fill, insert cartridge, ready to use immediately. |
| Certifications | ✓ ETH Zurich University Filtration Report · Swiss Safety Center · ISO 13485 Third-party independent academic testing for full PFAS spectrum performance. | – B Corp · Climate Neutral · NSF 372 (lead-free materials) Strong sustainability/material-safety certifications. No published independent contaminant-removal certification (NSF 53, equivalent academic testing, etc.). |
| Country of manufacture | = Switzerland (Jona, SG) Swiss Made under the Swissness Ordinance. 316L medical-grade stainless steel. | = Germany (Munich-based brand) German brand. Manufacturing partner locations not publicly itemised on the product page. |
Common Questions
Does everdrop remove PFAS?
everdrop's water filter cartridge is an activated carbon block designed for chlorine, taste, lime, and some heavy metals. The company does not publish independent third-party certification data confirming PFAS removal, particularly for short-chain PFAS (PFBS, PFHxA, PFBA, GenX) which are increasingly prevalent in European tap water as legacy long-chain PFAS are phased out. If your priority is PFAS protection, a certified selective adsorption filter — like the Mam Nature Swiss Fine Filter, independently verified by ETH Zurich University at up to 99.98% — addresses the full spectrum.
Is everdrop more sustainable than Mam Nature?
It depends on what you measure. For packaging and disposable plastic waste compared to traditional pitcher systems, everdrop is a strong sustainability story — refillable glass carafe, recycled-plastic cartridges, B Corp certification. For total system longevity and cartridge throughput, Mam Nature's annual cartridge cycle (one cartridge per year, multi-decade 316L housing) produces materially less waste over 10 years than a monthly carafe cartridge cycle. The two products optimise different sustainability dimensions.
Can I use everdrop and Mam Nature together?
Technically yes, but it would be redundant. If you install a Mam Nature Fine Filter at the point-of-entry, all water — including any water poured into an everdrop carafe — is already PFAS- and heavy-metal-filtered. The additional everdrop cartridge would provide no further filtration benefit. Some households still keep a small carafe for chilled drinking water, which is a use-case rather than a filtration need.
Which is better value over 10 years?
For drinking water at one location, everdrop is cheaper upfront and over 10 years (~€1,200–€1,500 total). For whole-house coverage — drinking, cooking, shower, bath, and appliance water — Mam Nature works out to roughly €0.002–€0.004 per filtered litre across the entire household, materially lower per litre than the ~€0.08–€0.10/L of a refillable carafe used only for drinking. The comparison comes down to coverage: one tap vs. every tap.
Does everdrop protect shower and bathing water?
No. everdrop is a carafe filtration product. Shower, bath, laundry and all other water sources in the home are unfiltered. PFAS and chlorine exposure through skin absorption and steam inhalation during showering is a well-documented concern that drinking-water-only filtration does not address.
