I've raised £1200 to pay for anti-COVID air filter units for Kingshill School, Ware

This Christmas we are kicking off quite a big fundraiser – after your amazing generosity over the last term, we realise this is a lot to ask. Please read on for further information.
The school is trying to raise £1,200 to fully kit out all classrooms with HEPA (high efficiency particulate air) filter units and to buy replacement filters to keep them running effectively.
The Department for Education has recently changed its guidance on air quality in educational settings and recommended the use of filters, to improve ventilation in classrooms and help prevent the spread of COVID-19.
Unfortunately, the models offered on the Government’s recommended ‘marketplace’ are very expensive (£400-£1200) and therefore out of reach for Kingshill. However, equally effective HEPA filters can be bought for ~£180-200 each. These are the units we want to buy.
We realise this is an expensive time of year for everyone and you have all contributed so much already. If you are unable to contribute, please could you share this fundraiser with your friends and family?
If your employer also runs any charitable schemes (match funding, community project donations etc) that you believe this might qualify for, please could you also consider sharing this fundraiser with them?
Anything you can do to help us get the school kitted out for the Spring term would be very much appreciated.
Thank you so much. Please enjoy the Christmas performances and have a wonderful festive season.
