I have an Aller Air purfier and I need to replace the filter and I'm not sure which one to get. Can you please help with this?|
A: As a general rule of thumb, AllerAir models have 3 layers of filtration in their units, a thick bed of activated carbon, a HEPA wrap/drum, and a prefilter with the prefilter needing to be replaced the most frequently of the three. The filter style can vary some among specific models.
Contact customer service and they should be able to walk you through which filters need to be changed. CS@ACHOOALLERGY.COM or call toll free, 1-800-339-7123.
