Purimax vs. DuraFry: Two Oil Extension Approaches, One Clear Winner for Independent Operators
DuraFry brings a consultant to your kitchen. Purimax brings results to your fryer — starting today, no appointment needed.
DuraFry is an interesting company. Founded in 2017 by a chemist and a veteran restaurateur, they built a patented oil treatment powder around real science and a genuine frustration with how poorly most commercial kitchens manage their frying oil. Their story is credible, their product is legitimate, and their consultative approach to oil management is thorough.
But thoroughness has a cost — in time, in process, and in access. DuraFry's model involves on-site technician visits, 4-week trial programs, custom SOP development, and ongoing monitoring. That's a meaningful commitment for an independent restaurant operator trying to cut their oil bill, not hire a consultant.
This comparison looks at DuraFry versus Purimax honestly — where each product's approach makes sense, and where the model itself becomes the barrier.
What Is DuraFry, and How Does Their Model Work?
DuraFry Solutions International is a U.S.-based company founded in 2017 by Bill Trent (chemist) and Michael Aoun (restaurateur). Their patented product — Dura-Fry powder — is a food-safe, FDA-approved oil treatment powder that works by removing polar compounds and degradation byproducts from frying oil. They also make an "OptiPad" filter pad that embeds the powder directly into filtration media, eliminating the manual powder addition step.
DuraFry's published results are compelling. Their model targets reducing oil changes from 100+ per year to approximately 26 — extending soy oil life to 12–14 days and beef tallow to 22 days. They use TPM (Total Polar Materials) testing via the Testo 270 instrument to measure oil quality quantitatively rather than relying on visual or smell assessment.
But here's where the model gets complicated for independent operators:
Initial contact and survey
You complete a baseline survey to establish your current oil management practices and frying setup before any trial begins.
Technician visit — on your oil change day
A DuraFry technician arrives at your kitchen on the date of your regular oil change to benchmark TPM levels and train your crew on application and measurement protocols.
2–5 day technician presence
The DuraFry tech stays at your location for 2 to 5 days to guide oil management practices during the initial rollout period.
4-week data collection
Your team collects data for four weeks while DuraFry monitors results remotely and prepares a savings analysis with tailored SOPs.
Results review and SOP delivery
DuraFry provides a final savings report and customized standard operating procedures for your kitchen's ongoing oil management.
What Is Purimax, and Why Is the Access Model Different?
Purimax is a commercial frying oil extension powder built on advanced synthetic adsorption science — formulated to target the full spectrum of commercial oil degradation: free fatty acids, polar compounds, oxidative byproducts, and polymerization products. The science behind the product is substantive. The difference from DuraFry is in how you get it and how you use it.
You order Purimax at purimax.com. It ships from our warehouse in Spanish Fork, Utah. It arrives at your restaurant. You apply it to your hot frying oil. Your oil lasts longer, your food fries more consistently, and your oil purchasing cost drops by 30–50%. No technician visit. No 4-week baseline. No survey to complete before you can start.
That simplicity isn't a lack of science — it's a design choice. The right oil treatment for the vast majority of commercial restaurant operators is one that works reliably, applies simply, and doesn't require a consultant program to implement. Purimax is built on that principle.

Which Model Fits Your Operation?
| Operator Type | Best Fit | Reason |
|---|---|---|
| Large chain with ops team and data infrastructure | DuraFry or Purimax — evaluate both | DuraFry's consultative model adds value when you have the bandwidth to use it |
| Independent restaurant (owner-operated) | Purimax | No bandwidth for 30-day trial; need results now, not after a program |
| 2–10 location regional chain | Purimax | Consistent, self-applied treatment across all locations without scheduling technician visits |
| Ghost kitchen or delivery concept | Purimax | Lean operations can't absorb a consultant engagement — direct ordering fits the model |
| Franchise operator (individual franchisee) | Purimax | Corporate may not have approved DuraFry at your specific location; Purimax available direct |
Frequently Asked Questions
Does Purimax offer any kind of trial or guarantee?
Yes. Visit purimax.com for current trial and satisfaction options. Unlike DuraFry's program which requires a technician visit and 4-week baseline before beginning, Purimax trial options let you evaluate the product in your kitchen on your schedule.
DuraFry uses TPM testing to verify results. Does Purimax recommend this?
TPM (Total Polar Materials) testing is a legitimate and highly accurate method of measuring oil quality — and yes, we encourage operators who want quantitative data to use a TPM meter like the Testo 270. That said, most operators can evaluate Purimax's performance through the practical indicators they already use: how often they're changing oil, food color and flavor consistency, and smoke and foam behavior during service.
Can I use Purimax without changing my current filtration routine?
Yes. Purimax integrates into whatever oil management routine you currently have. If you filter daily, Purimax works alongside that practice. If you don't currently filter, Purimax still delivers oil life extension as a standalone treatment. Adding filtration to a Purimax program will enhance your results further.
How do I order Purimax?
Go to purimax.com. Order what you need. It ships from our warehouse in Spanish Fork, Utah, directly to your restaurant. No distributor, no consultant, no program to enroll in.
