Scorching heat and humidity are just two of the nightmares we face during summer—especially if we live in areas with little ventilation or shade. Add to that the heat from cooking, possibly without air conditioning, and you’ve got the perfect recipe for an overheated kitchen full of persistent odors.

In this article, I’d like to share some expert advice, as a technician specialized in kitchen hoods, to help you enjoy your kitchen more comfortably during the summer months.

What Happens in the Kitchen During Summer?

In summer, when we cook, we often find ourselves in one of two situations:

Kitchen with air conditioning: We keep the windows closed to preserve the cool air and avoid wasting energy. The downside? Odors tend to linger longer without air circulation.
Kitchen without air conditioning: We open the windows to let air in and help clear out odors and fumes - but end up letting in heat and humidity instead.

To make things worse, high temperatures turn the cooktop into a mini heat generator: water evaporates faster, cooking fats release smoke more quickly, and the humid air acts like a "natural hood," trapping odors and vapors in the room.

The result? The kitchen overheats, unpleasant smells linger, and air quality quickly declines.

That’s why your kitchen hood becomes a real lifesaver in summer, helping promote air circulation and keeping your environment more livable.

Ecco che la cappa diventa il nostro salvavita in estate anche per aiutarci nel ricircolo dell’aria.

Why the Kitchen Hood Is Even More Important in Summer

I’ve emphasized many times in my articles how the hood plays a key role—not only in eliminating odors, but in keeping the kitchen environment healthy and comfortable.

During summer, this small appliance becomes even more crucial, offering benefits that affect the whole space:

No lingering fumes in the house: The hood prevents greasy vapors - which are more persistent in hot weather - from staying suspended in the air and settling on furniture and fabrics.
Reduces strain on the air conditioner: The hood helps remove warm, humid air, allowing the A/C to work more efficiently and reducing the need to open windows (which would cause thermal shock and higher energy use).
Limits condensation and mold: With the air conditioner on, surfaces - especially tiles and metal - become cooler. When hot vapors hit them, they condense. The hood extracts these vapors at the source, preventing them from condensing on cold walls. It also reduces indoor humidity, lowering the risk of mold growth.

Now that you understand just how important it is to use your hood in summer, here are some practical tips on how to use it the right way.

7 Practical Tips and Good Habits for Cooking in Summer

Turn it on early: Start the hood 5 minutes before cooking to let its surface adjust to the upcoming steam and heat, minimizing condensation.
Leave it on a bit longer: After cooking, let it run for 5–10 minutes to clear out lingering odors and vapors.
Adjust the speed: Use maximum speed only for heavy cooking (e.g. frying, grilling meat). For lighter dishes, use lower settings to avoid wasting energy. Let’s save where we can - starting with smarter energy use!
Use LED lighting: LED bulbs generate far less heat than halogen, which converts only 20% of energy into light. LED not only saves energy, but also reduces heat output.
Smart cooking: Use lids, pressure cookers, and ovens to limit steam generation during hot days.
Cold dishes: If you don’t feel like cooking (and want to avoid unwanted odors), cold recipes are the perfect solution. Think: caprese salad, bresaola with arugula and parmesan, tartare, or hummus - tasty, healthy meals with no need for heat!
Clean your filters more often: To keep your hood efficient, clean the filters more frequently in summer. You’ll find more details in the next section.

Summer Maintenance: What You Need to Do

In summer, maintaining your kitchen hood filters is even more important - and should be done more frequently than in other seasons. That’s because heat causes the grease trapped in the metal mesh filters to become more fluid, increasing the risk that it drips into pots and compromises food hygiene during cooking.

Also, if you have a recirculating hood, summer heat and humidity cause activated carbon filters to become saturated more quickly, reducing their odor-absorbing power.

Here’s how to take care of your hood in summer:

Clean the grease filters every two weeks to prevent saturation and the risk of grease dripping into food.
Replace activated carbon filters at the start of the season to ensure they’re ready for summer. Remember: they must be intact and not saturated to maintain proper extraction performance. If you use long-life filters, regenerate them at the start of the season!
Frequently clean the hood casing: Wipe down the hood’s outer surface and the area around the filters to prevent grime from becoming baked on—if it heats up later, it could fall back onto your cooktop.

If your grease filters are heavily worn or encrusted, or if your carbon filters are saturated, don’t forget: at Filtro Cappa, we supply any type of replacement part for kitchen hoods—even older models that are hard to find parts for.

Esperienza eccellente. Bisogna inviare la foto dell’etichetta del prodotto e così i pezzi di ricambio esatti vengono verificati dal venditore. Risposta attenta e rapida. Risparmio garantito rispetto ai rivenditori fisici di zona: circa 30€ a pezzo nel mio caso. Consigliatissimo!

Prima esperienza di acquisto del filtro cappa metallico, ottima in facilità di ordine e tempi di consegna, non pensavo di trovare ancora il ricambio in quanto la cappa Faber ha 23 anni, sono estremamente soddisfatto, non escludo di acquistarne un altro da tenere di scorta quando torna disponibile sul sito

Ho trovato il filtro della mia vecchia cappa seguendo i consigli via chat che mi sono stati dati in quanto il vecchio modello non è più in produzione. La spedizione è stata velocissima e il filtro è perfetto. Grazie

Sostituzione motore ventola di aspirazione tutto ok. Il motore è arrivato imballato perfettamente confezionato onde evitare di essere sballottato e danneggiato. Montato sulla cappa airone angolare tutto ok. Rivenditore preciso e puntuale molto affidabile.
