About this model
Molekule sells premium air purifiers using PECO technology to destroy pollutants at a molecular level. The business combines an upfront hardware purchase with recurring replacement-filter demand, making the installed base and filter cadence important drivers of lifetime value beyond the original device sale.
The model must balance consumer-hardware economics with consumables. Demand requires education and acquisition spending, while inventory, manufacturing, freight, warranty, and channel mix affect cash and gross margin. Filter replenishment can improve retention and contribution margin if customers remain active after their initial purchase.
Model units sold, ASP, installed base, filter attach, replacement cadence, subscription adoption, and repeat purchases. Deduct hardware COGS, filters, freight, warranty, inventory, marketing, and support costs. Conversion, hardware margin, filter retention, CAC, inventory turns, and channel mix should drive scenarios.
A turnkey financial model
Live formulas, no hardcoded values
Outputs are driven by live formulas, so the workbook updates from its assumptions instead of relying on hardcoded results.
All assumptions in one tab
Inputs are clearly marked in the Assumptions tab and separated from calculations, making it clear what to change and what to leave intact.
Statements always balancing
For integrated-statement models, the balance sheet, cash flow, and supporting schedules tie through properly.
Distinct schedules for clarity
Debt, working capital, taxes, and cash flow can get messy quickly. We group calculations in clear schedules, not across disconnected tabs.
No hidden macros or external links
There are no unexplained external workbook links or macros to undermine auditability or portability.
Changes flow through the model
Update a key driver and see the impact carry through the forecast, financing, and return outputs. We never use hardcoded numbers in formulas.

How to build a detailed financial model for Molekule
A complete walkthrough of the business, drivers, and assumptions behind the downloadable Molekule model - distilled from its pitch deck and publicly available information.
Product & value proposition
- Core product: Molekule Air (launched 2017) - PECO-based air purifier at $799 (shown as "Molekule Home One").
- Second product: Molekule Air Mini - smaller form factor, also sold DTC.
- PECO (Photo Electrochemical Oxidation): 20 years R&D, University of Florida; peer-reviewed, third-party tested, patented process, proprietary manufacturing.
- Key differentiator vs. HEPA/Carbon: destroys mold, allergens, viruses, VOCs, bacteria at molecular level rather than trapping; independent lab tests (U Minnesota, U South Florida) show pollutant percentage balance drops to minimum detection levels (~10-15% balance at 140 min vs. HEPA staying ~105% and Carbon rebounding to ~75%).
- Roadmap: Connected device / app (air quality monitoring); commercial vertical (product image redacted in deck).
Market
- US addressable sufferers: 25M asthma, 80M allergy, 166M pollution - total ~271M US sufferers.
- Global addressable sufferers: 300M asthma, 800M allergy, 3B+ pollution.
- Mortality framing: 3.3M deaths annually from air pollution globally.
- Indoor air can be 5x more polluted than outdoor.
- No TAM/SAM/SOM dollar figures provided in deck.
Revenue model
- Hardware (DTC): Molekule Air at $799; Molekule Air Mini at unspecified price.
- Filter subscription: $129/yr per device.
- Connected device / app subscription: described as "building value added subscription experience" - pricing not disclosed.
- Commercial: mentioned as a second vertical (hospitals, offices implied) - no pricing or channel detail.
- Channel: DTC (own website implied); no retail channel mentioned.
Traction & metrics
- ~200% growth in repeat customers (Molekule Air).
- 3x increase in YoY filter subscription revenue since launch.
- Customer reviews: 1,004 reviews for Molekule Air (4.5 stars); 42 reviews for Molekule Air Mini (5 stars).
- Launch year of first product: 2017.
- No absolute revenue, units sold, or customer count figures disclosed.
Unit economics
- Hardware ASP: $799 (Molekule Air).
- Filter subscription: $129/yr.
- No CAC, gross margin, LTV, or payback period data in deck.
Competition / moat
- Incumbents: HEPA (invented 1940s, Manhattan Project) and Carbon filters - framed as outdated and ineffective.
- Moat: Patented PECO process + proprietary manufacturing; 20 years academic R&D; peer-reviewed science; third-party lab validation.
- No direct competitor companies named.
Team & funding ask / use of funds
Recommended financial model
- Archetype + why: DTC hardware + recurring subscription (consumables) model. Molekule sells a high-ASP device once and earns recurring filter revenue annually - classic razor/blade. The emerging connected-device subscription adds a potential SaaS-like layer. Model should capture both streams and their interplay.
- Forecast horizon & granularity: 5 years (Y1–Y5); monthly for Year 1 (inventory/cash flow sensitivity), quarterly thereafter.
- Key drivers & assumptions:
| Driver | Value / Source |
|---|---|
| Flagship ASP - Molekule Air | $799 |
| Filter subscription price | $129/yr per device |
| Repeat customer growth rate | ~200% YoY - proxy for retention/re-order; treat as cohort re-purchase rate |
| Filter subscription revenue YoY growth | 3x since launch |
| Air Mini ASP | ~$399–$499; typical 50% discount vs. flagship for mini SKU |
| Gross margin - hardware | 40–50%; premium DTC hardware benchmark |
| Gross margin - filter subscription | 60–70%; consumable with lower COGS vs. device |
| CAC (DTC blended) | $150–$250; mid-range DTC health/wellness benchmark |
| Filter attach rate (Year 1 post-purchase) | 60%; customers who opt into annual subscription |
| Filter churn rate (annual) | 20%; consumable subscription benchmark |
| Connected-device subscription price | $4.99–$9.99/mo; smart-home app subscription comps |
| Connected-device attach rate | 25% of installed base in Y2+ |
| Commercial ASP (future) | $2,000–$5,000/unit; B2B uplift vs. consumer |
| Units sold Y1 (base) | 10,000 units; early DTC premium hardware ramp |
| Units growth rate Y2–Y5 | 50–80% YoY base case; declining as base grows |
- Scenarios (Base / Bull / Bear - which variables flex):
- Bear: Low unit growth (30% YoY), filter attach 40%, high CAC ($300), hardware margins compress to 35%.
- Base: 60% unit growth, filter attach 60%, CAC $200, hardware margins 45%.
- Bull: 100% unit growth, filter attach 75%, CAC $150, commercial channel contributes by Y3, connected subscription launches Y2.
- Required sheets / outputs:
- Assumptions - all drivers in one tab, color-coded inputs.
- Unit Sales & Cohort Build - new units by period; cumulative installed base by cohort.
- Revenue - hardware revenue, filter subscription revenue (cohort × attach × churn), connected subscription revenue.
- P&L (Income Statement) - revenue, COGS by stream, gross profit, S&M (CAC × new units), R&D (assumed), G&A, EBITDA.
- Cash Flow - operating cash, capex (tooling/inventory), working capital (inventory days, payables).
- Balance Sheet - inventory, AR, AP, cash.
- Unit Economics Summary - LTV (device + filter stream NPV), CAC, LTV/CAC ratio, payback period.
- Scenario Toggle - dropdown to switch Base/Bull/Bear, auto-updates P&L and cash.
- Dashboard - KPI cards: installed base, ARR (subscription), blended gross margin, CAC payback, cash runway.

Created by ex-finance professionals
Hey, I’m Alex and I created Finamodel.
Over my years in the finance industry I kept building the same models over and over again. Same structure, same assumptions, different logo. So I started building frameworks to turn them into clean, reusable templates.
Every model here is one I’d actually use for a client, and I personally vet each one before it goes up.
I’m not an expert in every industry, but I’ve built enough models to know what belongs in one. And when something is completely foreign to me, I reach out to my network for experts to work on our models with us.
Having a template library on hand cuts a first build from hours to minutes.
Need help finding your model? You’ll find me in the Finamodel app!
