Welcome back to everyone who spent the day at Dyson HQ talking about allergies - hope you had a fun, interesting and useful day .
Please can you use this thread to post your feedback about the day - including anything new you learnt about allergies and how you can control them, your dust busting tips, how you are finding your new Dyson Allergy vac, what feedback you had from the Dyson microbiologists on the dust sample you took with you, and anything else you think other Mumsnetters with allergies in their family may find useful.
If you didn't attend the day but have questions for our new allergy-specialist Mumsnetters or for Dyson, please feel free to post them here too and we'll do our best to get them answered.
Thanks, MNHQ
