Updated 7 December 2025 Pure Air Guide guide for UK homes

Living in a rented property can present unique challenges, especially when it comes to managing dampness and humidity levels. Dehumidifiers can be a fantastic solution, but using them wisely is essential to avoid any potential conflicts with your landlord.

This guide will explore the best practices for using a dehumidifier in your rental home, highlighting the benefits, potential drawbacks, and practical tips for ensuring you stay on good terms with your landlord.

Understanding Humidity and Dampness in Rental Properties

Many UK homes, particularly older properties, are susceptible to high humidity and dampness due to inadequate insulation and ventilation. Understanding how humidity affects your living space is crucial.

  • Humidity Levels: Ideal indoor humidity levels are between 40% and 60%. Anything above this can lead to condensation and mould growth.
  • Damp Signs: Look for visible signs like mould on walls, peeling paint, or a musty smell.
  • Causes: Common causes include poor ventilation, drying laundry indoors, and cooking without proper extraction.

Choosing the Right Dehumidifier

When selecting a dehumidifier for your rented home, consider the following factors:

  • Size: Choose a unit suitable for the size of your room. Smaller units are typically adequate for bedrooms and bathrooms, while larger models may be needed for living areas.
  • Type: There are two main types of dehumidifiers: refrigerant and desiccant. Refrigerant models are suitable for warmer temperatures, while desiccant models work better in cooler conditions.
  • Noise Level: Consider the noise level of the dehumidifier, especially if you plan to use it in a bedroom or quiet space.

Using Your Dehumidifier Effectively

To maximise the effectiveness of your dehumidifier, follow these practical tips:

  • Placement: Position the dehumidifier in a central location away from walls and furniture to allow for proper airflow.
  • Settings: Adjust the humidity settings based on the room’s conditions. A lower setting may be necessary in particularly damp rooms.
  • Regular Maintenance: Keep the filter clean and empty the water tank regularly to ensure optimal performance.

Communicating with Your Landlord

Good communication with your landlord can prevent misunderstandings. Here are some strategies:

  • Discuss Your Needs: If you experience damp issues, inform your landlord. A good landlord will appreciate your proactive approach.
  • Document Issues: Keep records of any damp problems and your efforts to resolve them with the dehumidifier.
  • Ask for Permission: While dehumidifiers are generally acceptable, it’s wise to ask your landlord before making any significant changes to the property.
