After an air purifier. Would a stage 4 HEPA filter type remove both pollen and bushfire smell/smoke?
Update: In the end have ordered an InovaAir. Owned and made in Australia. Company is 17years old. A few good options, but not available for at least 1-2weeks due to the unprecedented number of people wanting their purifiers. Although the Melbourne store indicated 4-5weeks, and website does actually say at least 4weeks. Still worth having even if we don't have it now for the smoke as we are all allergy sufferers and have been meaning to get an air purifier.

Melbourne store also advised that the Xiaomi Air purifier(assume the model 3) was a cheaper alternative. Even that is at least 1-2weeks away and doesn't have a carbon filter.
It should. A HEPA filter is supposed to filter 99.97% of air particles down to 0.3 microns. Carbon filter and ionisation tech get rid of the smells. But in my experience purifiers only work well in bedrooms with door closed. In large living rooms the smell could be gone but my particle counter would still detect high count.
