The Problem With Recirculating Hoods

Recycling air isn’t cleaning air
Recirculating hoods don’t remove heat or moisture and rely on charcoal filters that need regular replacement.—they just push it back into your kitchen. Over time, this can lead to poor indoor air quality, triggering respiratory issues like asthma or bronchitis, eye irritation.
Even light cooking with LPG releases combustion gases like carbon monoxide, nitrogen dioxide, and unburnt hydrocarbons
In this video, I explain what vented (ducted) and recirculating (ductless) cooker hoods are as well as their pros and cons. Plus, I answer some popular questions I get asked about this cooker hood/extractor topic.

The Smarter, Healthier Choice

Why Ducted Venting Makes Sense
Our vented systems capture-->filter-->expel fumes safely outdoors.With lightweight PVC ducts, venting is now possible in almost every home.
✅ Removes smoke & odour ✅ Keeps kitchen cooler
✅ Protects lungs
✅ Extends hood & cabinet life ✅ Rust-free & HDB-friendly

What the Science Says
Cooking fumes can contain PM2.5, formaldehyde, and benzene — pollutants also found in traffic exhaust.Without proper exhaust, a small kitchen can hit unsafe air levels within minutes.

Watch & Learn
In Berkeley Lab's test kitchen scientist Brett Singer and his team are measuring the pollutants emitted by cooking foods and evaluating how effective various range hoods are in capturing the pollutants.
PM2.5 refers to fine particulate matter that’s 2.5 micrometers or smaller—about 30 times thinner than a human hair. Because of their tiny size, these particles can bypass your body’s natural defenses and penetrate deep into the lungs, even entering the bloodstream.Once inside, PM2.5 can:
🫁 Trigger respiratory issues like asthma and bronchitis
❤️ Increase the risk of heart disease and stroke
🧠 Affect brain development in children and cognitive function in adults
🧬 Contribute to long-term conditions like cancer and premature aging These particles often come from vehicle exhaust, industrial emissions, and even indoor sources like cooking or burning candles.
There's been a lot of talk about a gas stove ban, thanks to a new report that found 13% of asthma cases in kids are caused by gas stoves specifically. Is it all controversy or are there genuine dangers and health impacts you should be worried about?
