3.Effective Aluminum & Carbon Filter A high efficiency filter technology is a must in any condo kitchen hood to maintain a clean and fresh kitchen as greasy fumes will linger no matter how great the hood’s suction power is. Normal recirculation hoods are unable to totally filter airborne grease, as they tend to drift back to the kitchen via the hood’s outlet. Fotile resolves this issue with its fresh-air filter which comes with a carbon filter that is 2.4 times higher in density, allowing it to better filter airborne grease particles. Additionally there is also over 60% of activated carbon content which translates to higher absorption of airborne grease. The hood is also designed with a double-sided layered aluminium filter structure that reduces lingering grease on the carbon filter, thus ensuring a cleaner environment while extending the hood’s lifespan.
