The Internet Accidentally Started a Debate About Frying Oil
Muhammad Tayyab HassanNobody opens TikTok hoping to watch a frying oil filtration machine.
Yet, over the last few months, VITO Middle East videos have generated more than 50 million views and thousands of comments.
And judging by those comments, we accidentally started one of the internet's favorite debates:
"Should frying oil be filtered?"
What surprised us wasn't that people had opinions. It was how many misconceptions kept appearing over and over again.
Some people thought filtration magically turns old oil into new oil. Others thought we were encouraging restaurants to use degraded oil forever. Some compared it to changing a car's oil filter without changing the oil. And some were convinced that a $1 strainer could do exactly the same thing.
So we thought we'd do something unusual:
Let's answer the most common questions we've received. Not with marketing claims. Not with buzzwords.
Just with science and practical kitchen experience.
Misconception #1: "You're just cleaning old oil."
Yes.
And no.
Filtration removes food particles, carbon, crumbs, batter residue, and other contaminants from the oil. What it does not do is reverse oxidation or magically make degraded oil new again.
The purpose of filtration is to start with fresh oil and regularly remove the particles that are left behind after each batch.
Why?
Because those particles don't stop cooking when the food leaves the fryer. They continue burning in the oil, accelerating oxidation and degradation.
By removing them regularly, the oil degrades more slowly. That's the entire concept. Not restoring old oil. Not avoiding oil changes.
Simply preventing unnecessary degradation by keeping particles out of the frying process.
Misconception #2: "You can't filter chemistry."
Correct.
And we never claimed you could.
Oxidation, hydrolysis, polymerization, free fatty acid formation, TPM increase, and other chemical changes happen naturally during frying.
A filter cannot reverse those reactions. What it can do is remove the contaminants that accelerate them.
That distinction is important.
Misconception #3: "If the oil is degraded, it should be changed."
Absolutely.
This is probably the comment we agree with the most. If oil has reached its degradation limit, it MUST be replaced.
Filtration is not a substitute for oil replacement.
It is a tool that helps slow degradation before the oil reaches that point.
Misconception #4: "The oil is already oxidized."
Technically, every frying oil starts oxidizing from the first time it is heated.
The question isn't whether oxidation occurs. The question is how quickly it occurs. Removing carbonized food particles helps reduce additional oxidation and thermal breakdown.
That's why professional kitchens filter oil and monitor oil quality.
Misconception #5: "A strainer does the same thing."
A strainer is useful. Every kitchen should use one. But strainers primarily remove larger debris.
Professional filtration systems are designed to remove much smaller suspended particles that remain in circulation throughout the fryer.
Different tools. Different particle sizes. Different results.
Misconception #6: "Filtered oil is still unhealthy."
This statement can be true.
Oil quality is not determined by appearance alone. Clear oil can still be degraded.
That's why we and official food controllers recommend using objective oil testing methods such as digital frying oil quality testers, which measure TPM values.
Filtration removes contaminants. Testing determines when oil must be replaced. These are complementary processes, not competing ones.
But if you just filter the oil without objectively testing the quality, your filtered oil can still be unhealthy.
That's why professional kitchens use both.

Misconception #7: "What about free radicals?"
Another excellent question.
Free radicals and oxidation products are generated by heat exposure. Filtration does not remove free radicals once they have formed.
What it does do is remove carbonized particles that contribute to the reactions that create more degradation compounds.
Again:
The goal is slowing the process, not reversing it.
Misconception #8: "Just change the oil."
This is where things become interesting.
Professional kitchens have never changed oil after every batch. They manage oil. They monitor oil. They filter oil. And eventually they replace oil.
In fact, best frying results are achieved after the oil has been used a few times and not when it’s completely new.
The debate is not whether oil should be replaced.
The debate is whether good oil should be allowed to degrade faster than necessary when proper oil management can help maintain quality, reduce waste, and lower environmental impact.
Misconception #9: "Built-in fryer filtration is better."
Built-in filtration systems are excellent.
Many kitchens use them successfully, and we fully support regular oil filtration regardless of the method.
However, not all filtration systems work the same way.
Many built-in systems rely primarily on gravity-driven filtration, where oil is drained through a filter medium before being returned to the fryer.
VITO uses a pressure-assisted filtration process, continuously passing oil through a high-quality cellulose filter and removing particles up to approximately 5 microns. (1/10 of a human hair)
This allows very fine suspended particles to be removed before they continue burning in the oil and accelerating degradation. The result is not a replacement for built-in filtration, but an additional layer of oil management.
In fact, many kitchens use both systems together: built-in filtration for routine fryer maintenance and VITO for fine-particle removal during daily operation.
Different kitchens have different requirements, but the goal remains the same:
Cleaner oil, slower degradation, less waste, and better oil management.
The Biggest Misunderstanding
The biggest misunderstanding we encountered across millions of views was surprisingly simple:
Many people assumed filtration was being presented as a way to avoid changing oil.
It isn't.
Professional oil management has always involved multiple tools:
- Filtration
- Oil quality monitoring
- Proper fryer cleaning
- Scheduled oil replacement
None of these replace the others. They work together.
Final Thought
The internet gave us thousands of comments.
Some are supportive. Some are skeptical. Some are hilarious.
But one thing became clear:
People care about food quality. And they should. So if there's one thing we'd like people to remember, it's this:
Filtration does not make old oil new.
It removes the contaminants that accelerate oil degradation.
That's it. No magic. No miracle machine.
Just better oil management.
