Filter for Bathroom Fan

[Ferdinand]

Our fan for the downstairs bathroom exhausts to the integral garage (done by previous owner). It is a normal bog standard 100mm. I can understand the decision, since it would be a complex 10-12m run of ductwork to get to the real outside.

However, the white suite seems to collect a lot of dust, such that we would need to clean the tops of things daily or more. The suspicion is that something in the air pressure is causing dust to come back through when the fan is not running.

So I am looking for a filter to fit to stop blowback, before considering more extreme measures such as fitting the ducting and a mother-of-all-fans.

Can anyone recommend something?

Thanks

Follow up note after 6 momths.

 

I fitted the fan called the Airflow Icon, where the aperture opens like the petals of a flowers of a flower, and it fixed the problem 95%.

 

Has been reliable, and I am now fitting them for tenants s an anti-draught while not running device,

 

I bought mine from Amazon at slightly less than the price quoted above.
