Updated 2 April 2026 Pure Air Guide guide for UK homes

Cooking is a daily activity in many households, but it can often lead to lingering smells and damp odours. These unwanted scents not only affect the comfort of your home but can also lead to issues like mould and condensation if not addressed properly.

This checklist will guide you through practical steps to improve your kitchen air quality, reduce cooking smells, and prevent dampness. With a few changes and the right tools, you can create a fresher environment in your kitchen.

Ventilation

Good ventilation is key to reducing cooking smells and preventing damp. Here are some actions you can take:

  • Install an extractor fan: A quality extractor fan helps to remove moisture and odours from the kitchen. Ensure it is vented outside, rather than recirculating air.
  • Open windows: Whenever possible, open windows while cooking to allow fresh air to circulate. This can help dissipate cooking smells more quickly.
  • Use trickle vents: If you have double-glazed windows, consider using trickle vents to allow a small amount of fresh air in without compromising security.

Clean Regularly

Regular cleaning of your kitchen surfaces and appliances is essential to prevent the build-up of smells and moisture. Consider the following:

  • Wipe surfaces: Clean countertops and stovetops after each use to remove food particles that can cause odours.
  • Clean the oven and hob: Grease and food residues in the oven can contribute to unpleasant smells. Regularly clean these areas to keep them fresh.
  • Maintain the fridge: Check for expired food and clean spills promptly. A clean fridge helps to prevent odours from spreading.

Use Air Purifiers

Air purifiers can be effective in reducing cooking smells and improving overall air quality. Here are some tips:

  • Choose the right type: Look for air purifiers with HEPA filters, as they can trap particles and allergens, improving air quality.
  • Consider odour filters: Some air purifiers come with activated carbon filters that are particularly effective at absorbing cooking smells.
  • Check the Clean Air Delivery Rate (CADR): Higher CADR ratings indicate better performance in removing specific pollutants. Choose a unit suitable for your kitchen size.

Control Humidity

Managing humidity levels in your kitchen can help prevent mould and damp smells:

  • Use a dehumidifier: If you notice condensation on windows or walls, a dehumidifier can help to reduce moisture levels.
  • Monitor humidity levels: Use a hygrometer to measure humidity levels in your kitchen. Aim for levels between 40-60% for optimal comfort.
  • Keep the kitchen dry: After cooking, wipe up any spills or water to prevent dampness.

Natural Remedies

If you prefer natural solutions for combating kitchen odours, consider these options:

  • Vinegar: Place bowls of vinegar around the kitchen to absorb smells. It neutralises odours effectively.
  • Baking soda: Similar to vinegar, baking soda can absorb unwanted smells. Keep an open box in your fridge or on your kitchen counter.
  • Citrus peels: Fresh citrus peels can add a pleasant scent and help mask cooking odours. Place them in a bowl or simmer them on the stove.

Cooking Techniques

Some cooking methods can lead to stronger smells than others. Here are some techniques to consider:

  • Use lids: Cover pots and pans while cooking to contain smells and moisture.
  • Cook with windows open: If weather permits, open a window while cooking to allow smells to escape.
  • Try less odorous methods: Grilling or roasting can produce stronger smells compared to steaming or boiling. Consider alternative cooking methods when possible.

Check for Leaks and Damp

Inspect your kitchen regularly for signs of damp or leaks, as these can contribute to unpleasant smells:

  • Look for water stains: Check ceilings, walls, and around pipes for signs of dampness.
  • Inspect appliances: Ensure that appliances like dishwashers and fridges are not leaking water.
  • Address issues promptly: If you notice any leaks or damp, address them quickly to prevent further damage and smells.

Final Thoughts

Dealing with cooking smells and kitchen odours requires a combination of good practices and appropriate tools. Regular ventilation, cleaning, and the use of air purifiers and dehumidifiers can significantly improve the air quality in your kitchen. Additionally, natural remedies and mindful cooking techniques can help create a more pleasant cooking environment.

By following this checklist, you can take actionable steps to combat unwanted smells and maintain a fresher, healthier kitchen.

Frequently asked questions

How can I prevent mould from developing in my kitchen?

To prevent mould, ensure good ventilation, keep humidity levels between 40-60%, and clean up spills quickly. Using a dehumidifier can also help manage moisture.

Are air purifiers effective against cooking odours?

Yes, air purifiers with HEPA and activated carbon filters can effectively reduce cooking odours and improve air quality by trapping particles and absorbing smells.

How often should I clean my kitchen to prevent smells?

Aim to clean your kitchen surfaces daily. Deep cleaning appliances and areas prone to grease build-up should be done weekly or bi-weekly, depending on usage.

Can natural remedies really help with kitchen odours?

Yes, natural remedies like vinegar, baking soda, and citrus peels can effectively absorb and neutralise kitchen odours, making them a great addition to your cleaning routine.

What humidity level is ideal for the kitchen?

The ideal humidity level for a kitchen is between 40-60%. This range helps to prevent mould growth and keeps the air comfortable.

Should I use a fan while cooking?

Using a fan can help improve air circulation and reduce cooking smells. However, make sure it does not blow grease or smoke around the kitchen.
