See How ATMOS® Wall Works:

ATMOS® WALL circulates fresh, filtered air throughout the property and transforms the stagnant and stale atmosphere into a fresh, healthy and condensation free environment.
Here's how it works:
  • Our professional installers position ATMOS® WALL in your designated space.
  • A neat hole is cut in the exterior of your home and the discreet air vent is placed into position.
  • ATMOS® WALL draws clean air from outside and filters it before pushing it down into the home.
  • Fresh, filtered, clean air gently circulates around your home, reducing the pollutants and irritants that cause illness and allergies.
  • Humidity levels are also controlled to eliminate condensation and mould.
Once installed, you can simply forget it’s there & enjoy the benefits it brings.

ATMOS® Puts You In Control:

The myenvirovent app gives you complete control of your ATMOS® ventilation system at the touch of a button.

  • Filter indicator
  • Adjustable boost functionality
  • Hours run meter
  • Adjustable airflow
  • Adjustable heater
  • Control summer mode
  • Enable or disable the heater
  • Use the app with most smartphones
App capability is only available with model ATF-A unless specified. 

The ATMOS® 10-Year Warranty*

Any repairs needed within the warranty period will be completed free of charge. All we ask is that you change the filter every 12 months. This period may be shorter depending on the environmental conditions. The unit needs to be serviced after 5 years.

Energy Saving Benefits

Minimum Energy Consumption

ATMOS® WALL is designed with the latest low watt motor technology to ensure minimum energy consumption and long term trouble-free life.

Reduce Heat Loss

To reduce humidity and condensation during the heating season, significant energy loss occurs by opening windows. ATMOS® WALL provides fresh, filtered air into the home, displacing humid air reducing the need to open windows and mitigating heat loss.

The ATMOS® Supply and Fit 10-Year Warranty

The product is covered by a 10-year supply and fit warranty, subject to the replacement of the filter every year and a service being completed after 5 years. Filters may need to be changed more frequently depending on the environmental conditions.

A Sustainable Choice

Part of our Lifetime Range® of products, ATMOS® WALL has been designed using sustainable components that can easily be recycled. This means we ensure the plastics used in our products never end up on landfill sites.

Health Benefits

With improved building features in our homes, such as cavity wall insulation, double glazing and draught proofing, ‘natural ventilation’ is prohibited. Stale air is trapped causing streaming windows, which ultimately leads to musty smells, dampness and mould growth. These mould spores are known allergens and become airborne at the slightest disturbance. The microscopic spores are then inhaled and can trigger respiratory problems such as asthma, dust allergies and hayfever.

The ATMOS® WALL Unit draws fresh air into the dwelling from outside and filters it before being delivered into the property. Moisture laden air is diluted, displaced and replaced with clean, tempered and filtered air. This eliminates or reduces surface condensation, which causes mould growth, providing a significant improvement in the health of asthma sufferers and general indoor air quality.

Environmentally Friendly

With a 10 year warranty and superior long life filters, the unit achieves the lowest life-cycle costing. All other component replacement is carried out simply and quickly by exchanging the consumable items. The worn out components are then taken back to the factory to be recycled thus reducing the impact on landfill and saving millions of pounds in replacement costs.

Pre-Heater and Hours Run Meter

The integral pre-heater is designed to temper the incoming air during periods of low external temperatures. A sensor monitors incoming air and pulses the heater to ensure temperatures are held to pre-set minimums. Two independent safety cut-out devices shut down the heater in the event of fan failure.The heater facility is controlled independently from the fan by a conveniently positioned enable/disable switch (optional extra). For monitoring of operational life and verification of usage, an integral Hours Run Meter is fitted.

How Does It Do This?

The ATMOS® WALL draws fresh air into the dwelling from outside and filters it before being delivered into the property. Moisture laden air is diluted, displaced and replaced with clean, tempered and fi ltered air.

As the unit deals with condensation, you don’t have to open windows, so you won’t need to turn the heating up to compensate in winter.

ATMOS ® WALL is available in 3 versions. The standard version (ATF) provides fit & forget functionality. Once installed you can leave it to operate autonomously. ATF-W comes with a remote control boost switch to increase the airflow when required and ATF-A provides full controllability through the myenvirovent App.


Your ATMOS® WALL unit can be linked directly to the AirSens® sensor. This means it reacts automatically to changes in air quality, instantly supplying more fresh air into the property to maintain a healthy environment when needed.

High Grade Default Filter

The unit has an ePM10 50% pleated filter as standard. Our medium grade filter captures stone dust and other lightweight airborne particles from entering the home. Optional filters available include ePM2.5 50% - our finest-grade filter captures small airborne particles, substantially reducing allergens and spores and Carbon ePM2.5 50% - finer particle filter including carbon. These are used to prevent odours and for highly polluted areas.
