Frequently asked questions

Ariosa DOT is a decentralised mechanical ventilation with heat recovery (MVHR) unit designed to continuously provide fresh, filtered air while extracting stale indoor air. It helps improve indoor air quality, reduce condensation and minimise the risk of mould growth.

The unit continuously extracts stale air from inside the room and replaces it with fresh outdoor air. During this process, heat is recovered from the outgoing air and transferred to the incoming air, helping to maintain indoor comfort and reduce heat loss.

Yes. By continuously removing excess moisture and improving air circulation, Ariosa DOT helps reduce the conditions that allow condensation and mould to develop.

No — the Ariosa DOT is designed to complement these devices, not replace them. It continuously exchanges stale air for fresh, filtered air and helps reduce condensation and moisture, while an air purifier targets airborne particles and a dehumidifier extracts excess moisture. Used together, they offer a more complete approach to healthy indoor air.

Yes. Ariosa DOT is designed for both new-build and retrofit applications and can be installed in existing properties without the need for extensive ductwork.

Ariosa DOT is ideal for individual rooms such as bedrooms, living rooms, home offices and similar spaces. For larger properties or whole-house ventilation requirements, alternative solutions may be more appropriate.

No. Ariosa DOT is a decentralised ventilation system, meaning it operates independently within a room and does not require a complex network of ducts throughout the property.

No. Ariosa DOT is designed for quiet operation, making it suitable for living spaces, bedrooms and home offices where acoustic comfort is important.

Yes. Ariosa DOT uses heat recovery technology to transfer thermal energy from outgoing stale air to incoming fresh air, helping to improve energy efficiency and indoor comfort.

Yes. The unit incorporates filters that help remove dust, pollen and airborne particles from the incoming air stream, contributing to improved indoor air quality.

Yes. Ariosa DOT can be controlled using a dedicated mobile application, allowing users to monitor and adjust system settings with ease.

Routine maintenance is minimal and typically involves periodic filter inspection and replacement to ensure optimum performance and air quality.

Filter replacement frequency will depend on usage and environmental conditions. As a general guide, filters should be inspected regularly and replaced in accordance with the user manual recommendations.

By continuously introducing filtered fresh air and reducing airborne particles within the home, Ariosa DOT may help create a more comfortable indoor environment for allergy sufferers.

We recommend installation by a suitably qualified professional to ensure optimal performance and compliance with relevant building regulations.
