FAQ
What's the difference between a Dehumidifier and an Air Cooler?
A Dehumidifier removes excess moisture from the air to tackle damp, mould and condensation, while an Air Cooler adds a light mist of moisture to dry air for a refreshing, cooling effect — they solve opposite humidity problems, so choosing the right one depends on whether your space feels damp or dry.
Can I use a fan and a dehumidifier in the same room?
Yes, running a Fan alongside a Dehumidifier is a great way to circulate air while tackling damp and condensation, helping both appliances work more efficiently together.
What size Air Treatment appliance do I need for my room?
For Dehumidifiers, match the extraction rate (12L, 20L or 30L) to your room size — larger or particularly damp rooms need a higher-capacity model. For Fans and Heaters, room size guidance is included on each product page to help you choose the right power output.
Are Emperial Air Treatment products energy-efficient?
Yes, our range of Dehumidifiers, Fan Heaters, Oil-Filled Radiators and Fans is designed with energy efficiency in mind, helping you manage your home's air quality and temperature without excessive running costs.
Do I need a dehumidifier if I already have a heater?
Heating alone doesn't remove excess moisture from the air, so if you're dealing with damp, mould or condensation, a Dehumidifier tackles the root cause while a Heater provides warmth — many customers use both together.
How do I stop condensation and mould coming back?
Regular use of a Dehumidifier, combined with good ventilation, is the most effective way to keep condensation and mould from returning, especially in bathrooms, bedrooms and poorly ventilated rooms.
