As we continue to navigate through the challenges posed by COVID-19, we’d like to share an update on how Vyair UK Ltd is responding.
In response to the Prime Minister’s announcement, Vyair UK will temporarily closed until further notice. We will continue to closely monitor developments related to the virus and update you as our plans evolve and change.
In the interim, our offices will be temporarily closed, however our online and telephone business will remain open.
Our website vyair.com is still operating and our Amazon shop is also available to purchase items from, emails will be monitored as normal and we will be able to send orders out as normal, however depending on courier availability there may be some delays with order deliveries, which we will work very hard to avoid.
Our technical department and telephone sales department is also still available however due to the need to have the telephone working remotely we may not be able to answers calls as swiftly as we would like. We apologise for the inconvenience and appreciate your patience and continued support.
We will be extending our returns policy to allow customers 90 days to apply for a refund or exchange.
Stay tuned for news on our reopening.

Elements contain preservative solution, therefore the permeate from the first hour of operation should be discarded. If the operating conditions in this document are not followed, no warranty of the element is honoured
Keep elements moist at all times after initial wetting. Permeate water obtained from first hour of operation should be discarded in order to flush the protective solution in the elements. CSM elements should be immersed in a protective solution during storage, shipping or system shutdowns to prevent biological growth and frost damage.
The standard storage solution contains one (1) weight percent sodium bisulfite or sodium metabisulfite (food grade). For short term storage of one week, one (1) weight percent sodium metabisulfite solution is adequate for inhibiting biological growth.
